Service Alert: Microsoft Email Delivery Delays — November 12-13, 2026

Microsoft is currently experiencing a widespread outage affecting Outlook, Exchange Online, and other Microsoft 365 services. As a result, emails sent to recipients using these services may be delayed until Microsoft resolves the issue.

If your mailing list includes a significant number of Microsoft email users, you may notice temporarily lower open and click rates while deliveries are delayed.

There is no need to resend your campaign. Direct Mail will automatically retry temporarily delayed deliveries until Microsoft's servers are accepting mail again. No action is required on your part.

For updates, visit Microsoft's Service Status page or Microsoft 365 Status on X. We'll also update this notice as more information becomes available.

Using the "Editing an address" trigger

This help article is for an old version of Direct Mail.

An autoresponder can be triggered when information about a subscriber changes. This could include changes like:

  • email address changed
  • name changed
  • data in a custom column changes

You could use this trigger for a variety of scenarios. For example, if you keep customer information in Direct Mail, you could trigger an email when something about that customer changes (like their mailing address, billing status, etc.). Changes made via Direct Mail or via our API (version 2) will trigger this type of autoresponder.

To use this autoresponder trigger, you will need to configure three settings:

  1. You will select which of your address groups to monitor for changes
  2. You will select which column to watch for changes (like first name, email, custom 1, etc.)
  3. You will select what kind of change triggers the autoresponder (e.g. "custom 1" equals "paid", or "custom 2" is not blank, etc.)

Members of your mailing list that have unsubscribed or hard bounced are automatically skipped.
