Scheduled maintenance - Email sending affected, 5 min
We are scheduling a maintenance window of 5 minutes on the 21st of September, 2026 at 7 am UTC. This maintenance will stop all email sendings (single email endpoint, bulk endpoint, SMTP). All emails sent during this period will be queued and sent afterwards, you might experience a slight delay. A maintenance event webhook will be triggered at that time, so you're notified closer to the date. We thank you for your patience whilst we do this operation.
