It also offers powerful filters that enable you to narrow down prospects based on industry, company size, job title, or even intent-based data. It comes with LinkedIn integration, so finding and reaching out to the right client is pretty efficient.
Apollo.io also excels in email outreaches. It doesn’t just provide verified emails; it also helps personalize and schedule outreach campaigns. The built-in sequencing tool means that I don’t have to rely on multiple tools for cold emails. And the best part? It tracks everything. I can see when someone opens an email or clicks a link.
While Apollo.io puts you out there and bolsters your outreach, there are also a few downsides. While it offers all that a sales team needs, the pricing is a little tricky. The credit system for email lookups and LinkedIn extensions means that you have to be strategic about the credits. I wish there were more flexible pricing options for mobile number access – it feels a bit steep for independent users.
Another thing that G2 users mentioned was the lack of lead text messaging abilities. With so many sales teams incorporating SMS into outreach strategy, it feels like Apollo.io should have capitalized here as well. And if you are on a lower-tier plan, some restrictions, like the 25-emails-per-day limit, can be frustrating.
Overall, if you are looking for a viable outreach and email marketing solution, then you should choose Apollo.io as it has the best in-house features for you.
What I like about Apollo.io:
- I loved the built-in granular analytics for email outreaches; the reports were accurate and to the point.
- I also liked how Apollo.io helps identify ideal consumer profile (ICP) using various filters like Revenue, Job titles, competitors, etc.
What do G2 Users like about Apollo.io:
“Within only two months already have driven new business. It slotted into my workflow very easily and was an immediately impactful addition. All of the information is very searchable and actionable. I have used this daily, and team members are also eager to use it for their workflows. My company appreciates that it implements well with salesforce and other programs, as we look to deploy at scale across the organization it will make this process easier.”
– Apollo.io Review, Joey L.
What I dislike about Apollo.io:
- I noticed that sometimes, even “verified emails” bounce or are invalid, which indicates that the email information requires some work.
- I found that Apollo.io can be inconsistent in providing data accuracy, particularly with job information and titles, affecting campaign quality.
What do G2 users dislike about Apollo.io:
“It doesn’t handle all use cases for existing contacts/customers – some of the contact collection automation is limited, such as pulling associated contacts to upcoming opportunities that we’d like to use to automate communicating upcoming renewals.”
– Apollo.io Review, Lachlan C.
5. ActiveCampaign
ActiveCampaign is a sales engagement platform that builds personalized email outreach and drip campaigns and improves conversion metrics, all from a unified platform.
It offers a distinct level of control and customization for email marketing, customer segmentation, and CRM automation, which is something I haven’t seen on many platforms.
One thing I absolutely love is how flexible the automation builder is. Whether I am setting a simple welcome sequence or a complex multi-setup workflow, it automates follow-ups and notifications based on past actions.
The automation flowchart makes it easy to visualize where each contact is in the funnel. With integrations into tools like ClickFunnels, Kajabi, and EverWebinar, it becomes a powerhouse for managing customer journeys.
ActiveCampaign also does a solid job of giving me data regarding open rates, click-through rates, and automation performance. The fact that I can preview emails within the automation workflow prevents me from juggling between multiple platforms.
While most people know ActiveCampaign as an email marketing tool, the built-in CRM is surprisingly powerful. It allows for detailed contact tracking, deal pipelines, and automated lead scoring, making managing sales funnels seamless.
However, each tool has its drawbacks, and ActiveCampaign can improve in some ways. The interface, while powerful, can feel a bit clunky, especially for beginners. A ton of functionality is packed into the platform, which can sometimes feel a little overwhelming.
If you are just starting out with ActiveCampaign, expect a learning curve on how to use it properly. Also, customer support can be hit or miss.
Some G2 users feel that ActiveCampaign can work on the branding on forms and emails in the Lite version. It’s a bit restricting if you try to keep everything clean and professional with the lite version. While importing contacts is mostly smooth, I have run into issues where blank fields overwrite existing data, which requires manual editing.
That said, ActiveCampaign is an end-to-end automation and campaign management platform that improves sales engagement and lead management workflows and integrates sales and marketing operations.
What I like about ActiveCampaign:
- I loved the customer support team at ActiveCampaign. They are incredibly fast and prioritize your queries.
- I also appreciated the easy and intuitive email formats that generate cold emails without disrupting the automation workflow.
What do G2 Users like about ActiveCampaign:
“ActiveCampaign is an incredible platform that is very easy to use. It has multiple capabilities for automated journeys and one-off eDMs. I also love that we can save our Outlook emails with supporters on AC so the whole team knows what’s happening.
There is also amazing customer support that we can use whenever we need it (not that we need it often). I use ActiveCampaign every single day at work and will continue to do so!”
– ActiveCampaign Review, Cassie F.
What I dislike about ActiveCampaign:
- I had some difficulty handling multiple automation because I was confused, and I couldn’t pay attention to the effect on the customer.
- The reports feature is a bit difficult to understand until you really learn the platform or attend a tutorial.
What do G2 users dislike about ActiveCampaign:
“I think they are weakest in sales/client follow-up tools. Managing Deals and activities with contacts (making calls, sending emails, etc) is quite cumbersome, and having good visibility of what is happening is difficult.
I also think the way of handling contact lists and unsubscribes is not optimal, and the automations lack some basic functionalities (e.g., updating contact/deal information with dynamic values).
– ActiveCampaign Review, Felipe S.
6. Instantly
Instantly offers a lead generation and marketing platform to personalize engagement, run marketing campaigns, and stay active in sales communication.
Setting up Instantly was very easy. It’s not just about blasting emails; it ensures they land where they’re supposed to, i.e., in inboxes and not spam folders.
Instantly’s backend optimization is proficient in handling email followups and warmups, and I saw a noticeable rate of difference between it and other platforms.
What I love most about Instantly is the built-in analytics. I get a clear view of how my campaigns are performing, who’s opening, who’s clicking, and who’s ghosting me. It’s like having an insights dashboard that actually gives me actionable data.
It also has a very streamlined approach to campaign management and lead attribution. I can easily set up sequences, tweak followups, update or modify content, and automate everything, which saves me a ridiculous amount of time.
Also, the support team is incredibly top-notch—responsive, helpful, and actually understands their own product (which isn’t always the case with SaaS support teams).
However, there were a couple of misses as well. While Instantly does integrate with some tools, I wish they’d expand their integration options. I’d love deeper connections beyond the usual features or transfers with CRM platforms.
Some G2 users were not happy with their tagging system. While it works, they still feel there is an even better way to manage and organize my leads. I also felt that campaign filtering could be a little better as sometimes all I want is to have a clear and uninterrupted view of my campaign metrics.
Overall, Instantly is one of the most adaptive and workable sales engagement tools. It can pivot your deals towards conversion and keep track of new and existing marketing campaigns.
What I like about Instantly:
- I like how responsive and well-organized the UI/UX is, with many easy-to-understand features and self-explanatory components.
- It also made launching an email campaign easy and simple for me because it offers “done-for-you” email accounts, saving me a lot of time.
What do G2 Users like about Instantly:
“Plain and simple, the #1 in the outreach game. I have been studying cold outbound reachouts for the past year, and every single road I took to discover knowledge about this topic led me to Instantly. They have a revolutionary tool that just continuously keeps growing. I also want to mention their customer support, as it truly is one of the most responsive teams out there. I log into my account every single day and am constantly looking for ways to improve, for which they’ve also provided material. Its interface is super easy to use; anyone could use it.”
– Instantly Review, George N.
What I dislike about Instantly:
- I wish I could filter leads within campaigns better for more targeted and quick prospecting and segmentation.
- I could not find a lot of information about when exactly the emails would go out during my early days, which created a little confusion.
What do G2 users dislike about Instantly:
“I wish there were more advanced customization options to tailor the platform to specific needs. Occasionally, I find that some features lack the flexibility I’m looking for. Additionally, enhancing the reporting and analytics section with more detailed insights would help fine-tune my campaigns even further. Also, please update the app. Make it more feature-rich.”
– Instantly Review, Jordan M.
7. Salesloft
Salesloft provides built-in multi-channel marketing features and AI automation to empower sales and marketing teams to manage leads better and improve their revenue.
After spending some time evaluating Salesloft, I have to admit that it has some serious plusses. At its core, Salesloft is an outbound marketing and sales tool that enables your client-facing teams to structure and organize sales accounts. It also helped me manage cadences.
I no longer have to worry about setting follow-ups or updating lead stages. Salesloft keeps everything organized and automates outreach and client nudges. The AI just works in tandem with all the operations. It predicts when my prospects are most likely to engage and even suggests email templates based on past interactions.
I really appreciate how well it integrates with Salesforce. With the sync, it is easier for me to view all my activities in one place and deal with sales queries smartly. The advanced analytics dashboard provides insightful metrics like open rates, click rates, or call conversion to analyze what’s working and what’s not.
Having said that, it is not always up and up. Setting up Salesloft was a little confusing. The interface isn’t always as intuitive as I’d like, and I found myself clicking through several menus just to tweak cadences.
Also, while the AI-driven recommendations are helpful, they aren’t always spot on. Sometimes, the recommendations didn’t make much sense for the sales prospect.
But, having said that, Salesloft caters to various sales teams and provides data-driven and personalized account-based automation to drive quick sales growth.
What I like about Salesloft:
- I loved how it allowed me to start work every day with a clear set of tasks and goals to help me stay updated.
- I found that it seamlessly syncs with Salesforce and provides personalized shortcuts to simplify outreach and improve productivity.
What do G2 Users like about Salesloft:
“I absolutely love cadences and how easy it is to create them for targeted use and consistent messaging. I’m not the most organized person, so ensuring I am making outreaches with proper spacing and messaging is amazing. Being able to listen back to my calls was something I never thought would be so valuable from both an info perspective but also from a coaching perspective. The analytics is just the right amount, showing you how your efforts stack up against your peers. Insight into cadence performance such as number of views, clicks or replies, and prospects showing interest.”
– Salesloft Review, Kevin S.
What I dislike about Salesloft:
- I wish there were more exhaustive design layouts and email templates on Salesloft to personalize emails better.
- I didn’t find it intuitive or user-friendly, especially in the beginning. The setup process took a lot of time.
What do G2 users dislike about Salesloft:
“It has significantly improved our sales process by helping us engage with prospects more efficiently. I like that the platform is straightforward, and the mobile app and browser extension are very helpful in tracking notifications and updates. They also seamlessly integrate with other tools like Gmail, LinkedIn, and ZoomInfo.”
– SalesLoft Review, Clifford T.
8. Clari
Clari is a revenue generation tool that provides a bird s-eye view of active sales pipelines, predictive analytics, and sales patterns and trends to capitalize on won deals.
If you scramble through spreadsheets and second-guess your efforts, Clari is an having an AI-powered sales coach that personalizes interactions. It helped me eliminate the guesswork out of forecasting and crunch numbers in real time, so I know which deals are moving, which ones are stuck, and which ones are likely to close.
One of the things I love most about Clari is that it integrates with Salesforce. It pulls in data automatically, cleans up inconsistencies, and updates CRM effortlessly.
Clari sets sales automation so that I don’t have to spend time mindlessly updating lead stages or engaging in manual CRM activity. That drives my focus to actual selling. The system also proactively nudges me about deal risks and AI-driven sales projections and even suggests next steps based on past interactions.
I also want to highlight Clari’s “forecasting engine” that improves the probability of scoring a deal. It just doesn’t show me what’s happening now- it predicts where my numbers are headed based on historical data and current deal activity.
I can also see my entire revenue funnel at a glance, from the early stages to closed deals. Clari also provides accurate contact information drilled down to the most granular level. And if you work on a leadership team that constantly asks for updated projections, Clari offers a one-view analytical dashboard for you.
Some G2 users mentioned that while the sync with Salesforce is mostly solid, it can sometimes be a bit slow. If you need real-time updates on every little change, it might take a little time.
Also, I wish the reports were a bit more customizable so that they could fit my workflows. And while the AI insights are great, it would be even better if Clari provided more prescriptive recommendations rather than just pointing to tasks.
All in all, Clari is a robust revenue management and sales engagement platform that monitors your lead generation workflows and gives you a prediction for revenue growth.
What I like about Clari:
- I like that I can create and send thousands of emails in bulk every day and that Groove support is always there to answer immediate queries.
- I didn’t have a hard time understanding and learning Clari as it was extremely user-friendly and intuitive.
What do G2 Users like about Clari:
“I like how Clari integrates with Salesforce and makes updating and managing my deals easy. The opportunity grid is particularly useful because it puts all the key information I need right in front of me. I can update fields like close dates and next steps directly in Clari, and it syncs back to Salesforce, which saves me a lot of time. The ability to configure the columns and views to match my workflow is also a big plus. It helps me prioritize my tasks and stay organized.”
– Clari Review, John D.
What I dislike about Clari:
- I struggled a bit to manage the Clari application across all products and got a little lost in the process.
- While the analytics are top-notch, some additional customization or personalization would have helped me better.
What do G2 users dislike about Clari:
“What I find least helpful is that some of the features that are reported don’t actually tell me where that information is coming from. I.e. Where my weighted number is coming from or how it is being calculated would be helpful. I wish I could also apply the same next action to multiple workflows instead of manually entering it in.”
– Clari Review, Jezni W.
9. FlashIntel
FlashIntel is a conversational AI agentic tool that streamlines sales discussions, resolves ad-hoc consumer queries, and extracts valid data points from sales conversations to gauge the potential of the lead. It also helps achieve around 30% customer retention.
One of the standout features for me is Flashinfo, which is their sales intelligence platform that makes prospecting easy. Their data accuracy has ridiculously improved over time, and it allows me to pull accurate lead information for nurturing.
With just a few clicks, I can pull enriched, high-quality, verified information for distinguished decision-makers. It also integrates well with multiple CRMs, though I found that some integrations need a bit of manual tweaking.
One of the key differentiators is also AI-powered lead scoring. FlashIntel helps prioritize leads based on real engagement metrics, which means that I don’t have to waste time chasing low-quality prospects.
Another feature, email automation, and deliverability tracking are also super handy. It’s like having an AI sales assistant working in the background who knows when to send which email and personalizes the response while logging the number of delivered emails.
But FlashIntel lacks a little in terms of providing outdated contact information. Sometimes, I extract inaccurate details about a contact that deteriorate the chances of a lead response or future conversion.
Another aspect that FlashIntel can improve is its pricing. As I glanced at the pricing, I noticed that it appears more suitable for enterprises than small businesses. This may create budget problems for early adopters or small business owners with limited revenue.
Overall, FlashIntel automates consumer queries and sales objections, integrates with CRM, and offers personalized content creation tools to simplify the lead journey.
What I like about Flashintel:
- I am in awe of the auto-dialer, which made my job easier by allowing me to dial 10 numbers in one go.
- The most impressive part for me is how seamlessly it integrated with multiple content management systems (CMS) and improved efficiency.
What do G2 Users like about Flashintel:
“This program is the perfect solution for sales and marketing folks since it contains all of the capabilities that a sales and marketing geek requires. This is the reason why I like this platform a lot and subscribed to it myself. The customer support is also good, which further makes things easier. I integrated it into my CMS, which was a work of a couple of seconds.”
– FlashIntel Review, Maxwell L.
What I dislike about Flashintel:
- I felt like data in the platform needs to be more specific and targeted towards niche marketers.
- I saw a discrepancy in the contact details (like email information) that appeared to be incorrect.
What do G2 users dislike about FlashIntel:
“Inaccurate prospect data poses a substantial issue for me as a marketer. Even verified data can be riddled with errors, which is unsatisfying. They really need to update the data almost twice a week.”
– FlashIntel Review, Jennifer N.
10. Bigin by Zoho CRM
Bigin by Zoho CRM is a start-to-end sales enablement platform that helps your sales team to onboard, nurture and convert leads.
What immediately sold me was drag-and-drop pipeline management. It was smooth and intuitive and let me track my deals without any fuss. I’ve also used other CRMs that are pretty chaotic and require a lot of time, but Bigin contradicts that.
Plus, the Bigin mobile app was outstanding in function. My team was up and running in minutes and started managing and closing sales accounts with ease.
One thing I love, and that is easy, is automated workflows. Setting up stage automation for our sales pipeline saved us a lot of manual work. The system automatically moves leads forward based on specific conditions of lead quality.
Because Bigin integrates so well with other Zoho products, it fits neatly into the existing ecosystem without causing too many headaches.
No matter how agile and sales-friendly Bigin is, it does have some drawbacks. Some G2 users struggled with reporting and analytics features. I wish the report generation process was a bit smoother, but it takes more effort than it should.
Integration with third-party tools is limited. For example, integration does not generate native Facebook leads, which is annoying if you invest in Facebook ads to generate leads.
While the automation is great, it lacks if/else conditional logic to set conditions on email triggers and provide a good customer experience.
Further, the pricing is a bit steep. If you are just starting out, you might feel a little restricted. But upgrading to a higher plan unlocks premium features that automate end-to-end lead nurturing.
Overall, Bigin by Zoho helps build personalized marketing automation pipelines for your sales and marketing teams to improve customer touch base from multiple platforms
What I like about Bigin by Zoho CRM:
- I love the easy to set up and visually appealing user interface, which saves time.
- I also appreciate the seamless integration with other apps that come within the Zoho suite to streamline online operations.
What do G2 Users like about Bigin by Zoho CRM:
“Easy to use and implement for an accountant like me; if you are new to using CRMs like I was, Bigin is the place to begin with. It easily integrates with my Zoho books and has very good features considering small businesses. The app is good, need of customer Support has not arised yet. Tons of videos and notes on the internet on how to implement etc.”
– Bigin by Zoho CRM Review, CA Jatin S.
What I dislike about Bigin by Zoho CRM:
- I feel to access more premium features, I require a plan upgrade that is a little expensive.
- I noticed that Bigin covers the needs of small businesses but is a bit basic for mid- to enterprise-size businesses.
What do G2 users dislike about Bigin by Zoho CRM:
“Most features my team requires are available on the express (lowest tier) subscription. However, certain useful features such as date/time triggered automation and 10+ custom fields on pipeline records are only available in the next tier (premier). You may quickly find yourself paying double in subscription costs to accomodate for business requirements – however still affordable compared to alternatives.”
– Bigin by Zoho Review, Naz H.
Best Sales engagement software: Frequently asked questions (FAQs)
1. What is the difference between a CRM platform and a sales engagement platform?
The main difference between a CRM and a sales engagement is that the former is used to store, capture, and manage leads, while the latter is deployed to run marketing campaigns, multi-channel outreaches, and drive pipeline visibility. With a CRM, you can update lead details, integrate contact with call tracking software, or store inbound leads.
But with SEP, you can re-engage cold leads or have a better view of the lead database to personalize engagement efforts.
2. Which are the best sales enablement platforms?
The best sales engagement platforms include Outreach, Salesloft, and Apollo.io, which are known for their AI-driven automation, multi-channel outreach, and CRM integrations. HubSpot Sales Hub also offers user-friendly options, while Groove offers a sales-enablement native platform to drive more pipeline management and consistently track SDR performance.
3. Is Hubspot a sales engagement platform?
HubSpot is primarily a sales platform, but HubSpot Sales Hub includes sales engagement features like email sequences, call tracking, cadences, multi-channel outreach, and campaign optimization that scale your revenue potential and provide a data-driven way to improve conversions.
4. What are the best free sales engagement platforms?
It includes Apollo.io (freemium plan) for multi-channel outreach, HubSpot Sales Hub (free tier) for basic email tracking and automation, and Mixmax (free version) for email engagement. While they aren’t feature-extensive, they provide features to improve sales cadences for new or small businesses.
5. How does sales engagement software integrate with my existing CRM and tech stack?
Sales engagement software can seamlessly integrate with your existing CRM cloud and tech stack via an application programming interface (API) connector. Most sales engagement platforms offer native integrations with CRMs like HubSpot, Salesforce, Microsoft Dynamics, and Pipedrive. Users should look for a bidirectional sync ( flow of leads via ERP connector and lead tracking via CRM) to attest that the data is transferred smoothly.
6. What AI-driven capabilities does the SEP offer for email and call automation?
The sales engagement platform offers AI-based automation that automates email delivery based on the lead stage in the purchase journey. It also extracts key insights from customer calls and associates the data with CRM accounts for real-time accountability and lead status changes, improving reps’ performance.
7. How does the sales engagement tool handle multi-channel engagement while ensuring compliance?
Most sales engagement tools support emails, SMS, LinkedIn, and chat within a unified interface. These tools comply with the GDPR, HIPAA, TCPA, and CAN-SPAM by providing opt-out management, consent tracking, and dynamic email tracking. These protocols ensure that the data remains safe and compliant.
Cross the (deal) bridge
Having a clear insight into your prospect’s interest level is imperative in a sales journey. Before SEP, CRM software was just a tedious medium for manual tasks and did not open any room for opportunity. Had I witnessed the revolution of a sales engagement platform, I would have experimented with a myriad of sales techniques and sales communication strategies and improved the output of my efforts.
Using these tools, I am convinced that proper SEP software, along with CRM, is the ultimate road to conversion. When you are ready to decide which software to invest in, check my two cents to refine your approach.
Refer to my peer’s analysis of the best AI sales assistants to employ efficient AI selling techniques and optimize productivity in 2025.
