The question asked, verbatim: best cold email software for startups

Brands named, in the order the engine gave

1. Instantly recommended
   Instantly (~$37-47/mo) - My default pick for a startup founder doing their own outreach.
2. Smartlead recommended
   Smartlead (~$32.50-39/mo) - Pick this over Instantly if you care most about deliverability controls and multi-client separation.
3. Lemlist recommended
   Lemlist (~$69/mo email, ~$109/user/mo multichannel) - Worth the premium only if your motion is genuinely multichannel.
4. Reply.io recommended
   Reply.io (~$49/user/mo) - Once you've hired SDRs and want AI-assisted sequencing plus real CRM-shaped workflows rather than a pure sending tool.
5. Apollo.io recommended
   Apollo.io - Not the best sender, but if you don't yet have a lead source, getting data + sequencing in one subscription beats stitching together a data vendor and a sender.
6. ZeroBounce mentioned
   Budget for domains and a verifier (ZeroBounce, MillionVerifier) alongside whichever you choose.

The answer, as recorded

Here's what I'd actually recommend, in order: **1. Instantly** (~$37-47/mo) - My default pick for a startup founder doing their own outreach. Unlimited email accounts on most plans, built-in warmup, a decent lead database, and a unibox that makes replies manageable. Pricing is based on contacts + sends, so it scales gently from "me sending 50/day" to a small SDR team. Best overall package if you're starting from zero. **2. Smartlead** (~$32.50-39/mo) - Pick this over Instantly if you care most about deliverability controls and multi-client separation. It's the agency favorite for a reason: white-labeling, sub-accounts, strong inbox-rotation and sending-pattern controls. Slightly rougher UI, slightly better plumbing. Cheapest serious entry point. **3. Lemlist** (~$69/mo email, ~$109/user/mo multichannel) - Worth the premium only if your motion is genuinely multichannel. It runs LinkedIn as an actual sequence step, which Instantly and Smartlead can't - so if you'd otherwise buy a second tool for LinkedIn, Lemlist is the cheaper total. Also the deepest personalization (images, dynamic landing pages), which matters for high-ACV, low-volume outreach. **4. Reply.io** (~$49/user/mo) - Once you've hired SDRs and want AI-assisted sequencing plus real CRM-shaped workflows rather than a pure sending tool. Overkill pre-PMF. **5. Apollo.io** - Not the best sender, but if you don't yet have a lead source, getting data + sequencing in one subscription beats stitching together a data vendor and a sender. Many startups start here and migrate sending to Instantly or Smartlead later. **Two things that matter more than the tool:** your sending infrastructure (separate domains from your primary, proper SPF/DKIM/DMARC, genuine warmup) and list quality. All five tools lose to a well-warmed setup on a mediocre platform. Budget for domains and a verifier (ZeroBounce, MillionVerifier) alongside whichever you choose. One caveat on sourcing: several top search results for this query are AI-generated listicles pushing products I can't verify exist (e.g. "Waalax," "Aplemarket"). I've only named tools with an established track record.
