Mail merge, without the spreadsheet ritual.

Write a letter once. Upload a recipient list. MergeDesk fills in the names, generates a PDF for each person, and sends it through the mailbox you already use.

Sign in

A campaign, in three steps

  1. 1. Details. Subject, sender, and the template.
  2. 2. Recipients. A CSV. MergeDesk checks the columns before anything is sent.
  3. 3. Review. Start, pause, and see who received it.

What it actually does

Built for teams that send personal letters at volume: renewals, statements, invitations, notices.

Campaigns from a CSV

Each row is a recipient. Columns become merge fields in the subject, the body, and any attached PDF.

Templates you can reuse

Write the letter once, keep it, and start the next campaign from it instead of copying last month’s file.

A PDF per recipient

Attach a PDF template and each person receives a document filled with their own details.

The mailbox you already have

Send through Microsoft Graph, SMTP, or Mailgun. The from-address stays one your organisation controls.

Progress you can pause

Watch a campaign while it sends. Pause it if something looks wrong. Retry the ones that failed.
