Postgun

Use case

A different attachment for every recipient

Invoices, event tickets, payslips, grade reports: any time each person needs their own file. Postgun reads your list, finds each recipient's file by a filename pattern you choose, and sends it through your Mailgun account.

How to do it

  1. 01

    Import the list

    CSV or Excel. Include a column that appears in each file's name, such as an invoice number or ticket ID.

  2. 02

    Upload the files

    Upload the files individually or as a ZIP.

  3. 03

    Match files to rows

    Set a pattern like {{invoice}}.pdf. You can also attach shared files that everyone receives, such as terms and conditions.

  4. 04

    Send

    Send a test first, then start. Pause, resume or cancel at any time, and retry failed recipients later.

Example

emailcompanyinvoiceattached file
[email protected]AcmeINV-2041INV-2041.pdf
[email protected]GlobexINV-2042INV-2042.pdf

Filename pattern: {{invoice}}.pdf

Questions

Can I combine personal and shared attachments?
Yes. Shared files go to everyone, and the pattern-matched file is added per recipient.
Are attachments sent from my own domain?
Yes. Everything goes through your Mailgun account and sending domain.
