Export mail from a domain

Download up to 31 days per mailbox as a ZIP with mbox, PDF notice, and metadata.

Domain admins (and roles that can manage mail on the domain) export mailbox archives from Domains → your domain → Export. Use this for legal holds, offboarding, or a durable backup for a date range.

Export screen with a 31-day range and Download per mailbox

Limits that matter

  • At most 31 consecutive calendar days per mailbox per download
  • Need older mail? Run another export with the next window
  • About 10 exports per user per rolling hour (server rate limit). If you hit it, wait and retry
  • Pick the range first, then download per mailbox from the searchable list

What is in the ZIP

Each download is a ZIP that typically includes:

  • Mail in .mbox form
  • A short PDF notice about the export
  • JSON / analytics metadata for the range

Exact contents can grow with the product; treat the ZIP as the full archive for that mailbox and window.

Steps

  1. Profile → Domains → open the domain
  2. Open Export
  3. Set Date range (31 days max)
  4. Find the mailbox → Download
  5. Keep the file somewhere safe; Postra does not keep a separate “past exports” locker in the UI

Who should not use this for day-to-day

Saving one conversation for yourself: message menu → Export as PDF. That stays on your device and does not need domain admin rights.

Before you close an account

Export anything critical first. Longer retention windows apply on Professional and above; Starter still lets you export before closure. See Close or restore your account.
