Sales engagement software runs the sequence: the emails, calls and LinkedIn touches a rep works through to reach a prospect. Our catalogue holds ten platforms doing that job with an editorial rating of 4.0 or better, and comparing them turned up something more useful than a ranking.
Five of the ten publish a price. Five won’t. Apollo.io starts at $49 a month with a free tier, while Outreach, Salesloft and Nooks ask you to book a demo instead.
That split isn’t a detail about their websites. It’s the clearest signal in the category of who each one is built for.
The published-price half
Apollo.io rates highest here at 4.5: a prospecting database of more than 230 million contacts with sequencing built on top. It’s also the only platform here with both a free plan and a published price, $0 through $119, read off its own pricing page. Start here if you want to start without a sales call.
Lavender at 4.3 is the cheapest entry at $29 and the odd one out, because it sends nothing. It coaches a rep while they write, scoring tone, length and personalisation in the compose window. Pair it with a sequencer rather than choosing between them.
Instantly AI at 4.2 and $37 solves a different problem again: sending infrastructure. Multiple inboxes, warm-up, deliverability. It’s the plumbing under cold outbound, not the sequence builder on top of it.
Reply.io at 4.1 has the cheapest paid entry of any platform here, $20, and the biggest gap between its name and its product. It now leads with Jason, an AI sales development agent that runs outreach and books meetings against a prospect database it describes as exceeding a billion records. You’re buying an agent, not a sequencer.
Klenty at 4.1 starts at $45 and is the most conventional platform here. Email, calls, LinkedIn tasks and SMS run in one multi-channel sequence, with account-based playbooks over the top. Built in California, product team in Chennai.
Regie.ai at 4.1 is the most expensive published price at $180. It calls RegieOne an AI sales engagement platform. That’s a long way from the content generator it launched as, by way of agents in 2024.
The demo-gated half
Outreach at 4.2 is the enterprise standard: multichannel sequences, deal management, conversation intelligence and forecasting in one platform. It publishes no price. Our own listing records $100 a month, and that figure no longer appears anywhere on its pricing page, which asks for a demo instead.
Salesloft at 4.1 is the other half of that duopoly, and the site of the biggest change in this category. In December 2025 Salesloft completed a merger with Clari, after raising $245 million and reaching a $1.1 billion valuation on its own. Sequencing and revenue forecasting now sit in one company, and it publishes no price either.
Nooks at 4.1 began as a parallel dialer, letting a rep call up to ten prospects at once in a virtual bullpen. It grew into a wider assistant covering dialling, coaching and research. If your bottleneck is connect rate rather than email volume, it’s the one to look at. No published price.
JustCall at 4.0 rounds out the list at $29, bundling voice, SMS and WhatsApp with power and predictive dialling built for prospecting rather than for support queues.
What the pricing split tells you
Read the two halves side by side and the pattern holds. Everything with a published price is bought by a rep, a founder or a small team, and it’s designed to be started without talking to anyone. Everything demo-gated is bought by a VP with a seat count, a procurement process and an annual commitment.
Neither is worse. But the demo-gated platforms don’t hide the price because it’s low. When the two best-known names both refuse to publish a number, get a quote before you get attached.
The ratings say something too. Nothing here clears 4.5 except Apollo.io, and the spread from 4.0 to 4.5 is narrow enough that fit matters more than rank. A dialer and a writing coach both appear on this list, and they aren’t competing for the same budget.
Which one fits
- No budget approval yet: Apollo.io. Free tier, published price, data and sequencing together.
- Weak rep writing: Lavender at $29, alongside whatever sends.
- Deliverability trouble: Instantly AI at $37.
- Agent rather than tool: Reply.io and Jason, from $20.
- Connect rate as the bottleneck: Nooks or JustCall.
- Enterprise procurement: Outreach or Salesloft. Budget for the demo cycle.
Common questions
Is sales engagement software the same as an AI SDR?
No, though the line is blurring. Sales engagement software gives a rep a sequence to work, while an AI SDR runs the outreach itself, and Reply.io and Regie.ai now sit on both sides of it. We pulled the distinction apart in our guide to AI SDR tools.
Why won’t Outreach and Salesloft publish a price?
It’s because both sell annual contracts priced per seat, usually with a platform fee and a minimum. A single number would misrepresent what a fifty-rep deal costs. The practical effect is that you can’t compare them against Apollo.io or Klenty without a sales call.
Does a free plan mean anything here?
Two platforms on this list offer one: Apollo.io and Lavender. In both cases it’s usable by a single rep rather than a trial with a clock on it. Everywhere else, free means a demo.
What changed in this category recently?
Consolidation. Salesloft and Clari merged in December 2025, putting sequencing and revenue forecasting under one roof. Expect the rest of the category to pair execution with forecasting rather than sell either alone.
