## The answer, as recorded

Asked on 2026-10-15 through Claude (Anthropic) with web search (model claude-opus-5).

> Heads up on the research: a lot of what ranks for this query is vendor-owned comparison pages (Instantly and Apollo both publish "X vs Y" posts that they win) or thin AI-generated affiliate content. I've weighted toward things that are consistent across sources and match how these tools actually work.
> 
> ## What I'd actually recommend
> 
> **1. Instantly - the default pick for most startups.** Starts around $37-47/month, unlimited connected mailboxes on every plan, and the best managed warmup + inbox rotation in the category. It also bundles a B2B lead database (~40M contacts), so a solo founder can go from zero to sending without stitching three tools together. If you're pre-Series A and doing outreach yourself, start here.

> 
> **2. Smartlead - if you're technical or running outreach for multiple brands.** $39/month base, $94 for Pro, also unlimited mailboxes, and critically **no per-seat pricing** - a five-person team pays what one person pays. API-first with white-labeling, custom tracking domains, and granular send scheduling

Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
