## The answer, as recorded

> Here's what I'd actually recommend, in order:
> 
> **1. Instantly** - my default pick for a startup founder doing their own outbound. Unlimited sending accounts on the lower-tier plans (~$37-47/mo), warmup built in across every inbox, a unified inbox for replies, and a 160M+ contact B2B database included so you're not paying separately for leads. The "unlimited mailboxes" part matters more than it sounds: cold email at any volume means spreading sends across many inboxes, and per-mailbox pricing is what kills budgets.
> 
> **2. Smartlead** - pick this over Instantly if you're running outbound for *clients* (agency model) or you care most about per-mailbox economics at scale. Basic starts ~$39/mo, unlimited warmup included, and its rotation/deliverability infrastructure has the strongest reputation among heavy senders. Weaker UI and a thinner native lead database than Instantly.
> 
> **3. Saleshandy** - the value play. ~$34/mo entry, unlimited sending accounts, 850M+ contact database, AI sequences and a light built-in CRM. Worth a look if you want data + sending in one bill and Instantly's pricing is still a stretch.
> 
> **4. Apollo.io** - choose this if your real bottleneck is *finding* people, n

Answer Watch records what one AI answer engine said on one date, nothing more. 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.
