1. Apollo recommended
   Apollo.io - The default pick for most startups.
2. Apollo.io recommended
   Apollo.io - The default pick for most startups.
3. Instantly recommended
   Instantly - If your motion is high-volume cold email rather than full multichannel engagement.
4. per-seat recommended
   ~$47-$358/mo flat rather than per-seat, which matters a lot when you have 2-3 reps.
5. Smartlead recommended
   Smartlead - Same category as Instantly but more infrastructure-flavored: many mailboxes, shared warmup network, deliverability tooling, unified inbox.
6. Clay recommended
   Clay - Not a sales engagement platform in the classic sense, but it's where a lot of the best outbound teams now start.
7. Amplemarket recommended
   Amplemarket - The best all-in-one if you want multichannel plus AI agents without assembling a stack.
8. G2 recommended
   4.6/5 on G2 across 570+ reviews.

   Klenty or Mixmax - Worth a look if you have under ~10 reps and want something dead simple.

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them for a startup: **1. Apollo.io** - The default pick for most startups. It bundles a ~210M-contact B2B database *with* the sequencer, dialer, and email automation in one bill, so you're not paying separately for data and engagement. Free tier to start, then roughly $49-$149/user/mo. For anyone under ~$5M ARR this is usually the right answer, and you can be sending sequences the same afternoon. **2. Instantly** - If your motion is high-volume cold email rather than full multichannel engagement. Cheapest way to get real sending volume with mailbox rotation and warmup built in; ~$47-$358/mo flat rather than per-seat, which matters a lot when you have 2-3 reps. **3. Smartlead** - Same category as Instantly but more infrastructure-flavored: many mailboxes, shared warmup network, deliverability tooling, unified inbox. Pick this over Instantly if you're running multiple domains/brands or doing agency-style volume and sender reputation is your main constraint. **4. Clay** - Not a sales engagement platform in the classic sense, but it's where a lot of the best outbound teams now start. Waterfall enrichment, Claygent research agents, and a natural-language workflow builder let you build genuinely personalized lists. It added a native email Sequencer in late 2025, though it's limited (about 4 steps, ~24 emails/account/day) and has no calling or social. Pair it with Apollo or Smartlead for the actual sending. Pricing got steep after the 2026 overhaul: free tier, then $185/mo (Launch) and $495/mo (Growth). **5. Amplemarket** - The best all-in-one if you want multichannel plus AI agents without assembling a stack. 200M+ contacts, sub-3% bounce rates, intent signals, seven channels, and the Duo copilot with Signal/Research/Sequence agents. 4.6/5 on G2 across 570+ reviews. More expensive and more opinionated than Apollo, but less glue work. **6. Klenty or Mixmax** - Worth a look if you have under ~10 reps and want something dead simple. Both sit under ~$75/user, have low or free tiers, and set up in under an hour. Mixmax especially if your team lives in Gmail. **7. Salesloft / Outreach** - I'd skip these at startup stage. They're genuinely better at conversation intelligence, forecasting, and managing structured orgs, but they run ~$125-$165/user/mo and ~$100-$140+/user/mo respectively, require 6-12 month commitments, and the feature gap vs. Apollo is smaller than the price gap suggests. Graduate to them when you have 20+ reps and a sales ops person to own the config. **My actual advice:** start on Apollo's free tier, add Clay once you know which signals and personalization actually convert, and move sending to Smartlead or Instantly if volume becomes the bottleneck. Don't buy an enterprise platform before you've found a repeatable message.
