## The answer, as recorded

Asked on 2026-10-09 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually recommend, roughly in the order I'd try them:
> 
> **1. Smartlead** - my default pick for most startups. Unlimited mailbox connections and unlimited warmup on every plan, with pricing from ~$32-39/mo. The deliverability controls (rotation, per-inbox send caps, spam-test integration) are the best in the category, and it has a real API plus white-labeling if you ever do outreach for clients. Least likely to punish you as volume grows.
> 
> **2. Instantly** - the easiest to get running on day one. Similar unlimited-inbox model from ~$37/mo, better UI than Smartlead, and the bundled lead database + Inbox Placement tests mean you can go from zero to sending without buying three other tools. If you're a non-technical founder doing outreach yourself, start here.
> 
> **3. Lemlist** - the one to pick if your motion is multichannel (email + LinkedIn + calls) or highly personalized low-volume outreach to a few hundred good-fit accounts. Caveat: it's per-seat (~$69/mo email, ~$109/user/mo multichannel) with capped mailboxes per seat, so it gets expensive fast for volume plays.
> 
> **4. Apollo.io** - worth considering if you don't yet have a lead source. Data + sequencing in one subs
