Send Check

One email to many people is many emails. Check how each group will read it before you send.

Try an example:

1 · Your email

2 · Who's on the list

Split the list by facts you already have: how long they've been customers, last visit, plan, payment history.

CSV or Excel (.xlsx). Drop a file here, , or add segments by hand below. Claude sees only column summaries; names, emails, and phone numbers are never sent.
Checks your email against every group on the list.
1. Write your email.
2. Add who it's for: one person, or a whole list.
3. Press Check draft.
