## The answer, as recorded

Asked on 2026-10-19 through Claude (Anthropic) with web search (model claude-opus-5).

> 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) -
