The answer, as recorded

Here's what I'd actually recommend, in order: ## The sending platform **1. Instantly** - the default pick for most startups. ~$47/mo ($37.60 annual) on Growth, unlimited mailboxes and warmup on every tier, and the sending rotation/warmup just works without babysitting. It also bundles a lead database (SuperSearch) if you don't have a list yet, though that's a separate add-on cost. Best ratio of "cheap" to "doesn't get you blacklisted." **2. Smartlead** - $39/mo base, also unlimited mailboxes. Pick this over Instantly if you're technical or plan to run outreach for clients: the API is better, webhooks are more complete, and white-labeling is first-class. Slightly rougher UI, more knobs. **3. Lemlist** - $69/user/mo, and it's priced per *seat*, which hurts as you add reps. Worth it only if multichannel (email + LinkedIn + calls in one sequence) and heavy personalization are the core of your motion rather than volume. Note the $69 tier caps you at 3 mailboxes, which is a real constraint vs. the other two. **4. Apollo** - ~$49/user/mo. The reason to choose it is that prospecting data and sending live in one tool, so you skip a whole integration. Trade-off: the data is noisier than dedicated providers and the sending engine is the weakest of this group. Good for very early stage when simplicity beats quality. **5. Woodpecker** - the conservative choice. Deliverability-first, low volume, simple. If you're selling to a small, high-value list where one burned domain is a disaster, this is the safer tool. ## What actually matters more than the tool Pick any of the top three and your results will be decided by the infrastructure underneath, not the software: - **Buy separate sending domains** (variants of your main domain - never send cold mail from your primary). Instantly and Smartlead both resell preconfigured Google/Microsoft mailboxes, which is worth the markup to skip the DNS work. - **Google Workspace or Microsoft 365 mailboxes** beat cheap SMTP for inbox placement. Budget ~3-5 mailboxes per domain, ~20-30 sends/day each. - **A verification step** - Million Verifier or ZeroBounce - before every send. Bounce rate is the single biggest driver of domain reputation. ## My pick Start with **Instantly** + real Google Workspace mailboxes on 2-3 secondary domains + a verifier. That's ~$150-250/mo all-in and covers you to a few hundred sends a day. Move to Smartlead if you outgrow the API, or Lemlist if you discover your deals need multichannel touch rather than more volume. One caveat worth stating plainly: several of the "best of 2026" listicles ranking these tools are affiliate-driven (including one published by Instantly itself comparing Instantly to its competitors), so treat the ordering in those as marketing. The pricing figures and mailbox limits above are the parts I'd trust.
