Investigating Email Processing Delays (AU Region)

What to do

• Check whether you use SMTP2GO Email sending (SMTP service). Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 10h 45m it lasted.

  Anything that failed between 2026-03-31 23:08 UTC and 2026-04-01 09:53 UTC may need a replay.

• Subscribe to SMTP2GO's feed to hear about the next one first. RSS feed
