## The answer, as recorded

Asked on 2026-10-21 through Claude (Anthropic) with web search (model claude-opus-5).

> 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, Claygen
