How we rank (ranking v1, updated Nov 15, 2026)
Ranks are Milo's editorial judgment (v1, Nov 15, 2026), based on each tool's official documentation, product pages and public pricing pages, all checked on that date. Each tool is scored on four questions: (1) Does it finish the job end to end for a non-expert? (2) How good and reliable is the result? (3) How cheap is it to get started? (4) How mature and widely used is it? Hands-on tests and reader reports will be added weekly, and ranks will move when they show something new. Sponsors cannot buy or change a rank. Pricing tier is shown only when we confirmed it on the tool's official pricing page; 'freemium' means a free plan plus paid plans, 'paid' means no free plan (a trial or starter credits may exist).
Use cases for this job
CC
Research every lead and draft a personal email for each
A consultant had Claude Code turn a plain-language target profile into Clay searches, research each contact individually, and hand back a finished draft in his own voice for every lead.
Target: [INDUSTRY, SIZE, LOCATION, ROLE]. For each matching contact, research their company and recent public activity, then draft a 4-sentence email in my voice (examples: [PASTE 2 EMAILS]) that references one specific, true detail. Put everything in a table for me to review.
A GTM founder scraped, enriched, personalized and launched an outbound campaign by prompting Claude Code with a GTM CLI in a few exchanges, cutting setup from hours to about forty minutes. The first 180 emails produced eight positive opportunities, he reports.
Build an outbound list for this ideal customer: [ICP]. Find 200 matching companies and the right decision maker at each, verify emails, and write a short personalized first line for each based on something true and recent about the company. Output a CSV. Don't send anything.
