Mail MergeSign in

Send one personalized email per row of your CSV — over your own SMTP.

A self-serve mail merge for plain-text email. Upload a CSV, compose with merge fields, preview and test-send, then fire a batch through your own SMTP server — with live progress and a record of exactly what was sent.

Credential delivery
Send each person their own login, token, or access details — one row, one email, no shared inbox.
Per-row documents
Attach a different file to each recipient — payslips, certificates, invoices — matched from a column in your CSV.

What you get

  • Your own SMTP, verified before any send
  • Merge-field autocomplete for subject and body
  • Row-by-row preview with empty-value warnings
  • Whole-batch test-send to one address
  • A confirmation gate before every live send
  • Live per-recipient progress and a downloadable record
  • A CLI and MCP server for agents and scripts

Bring your own SMTP. Credentials are encrypted at rest. No shared sending infrastructure, no tracking pixels, no lock-in.
