Incident Report
Summary AI Generated
MailerLite experienced a major 7.5-hour outage affecting all core services including email sending, landing pages, websites, API integrations, subscriber management, and automations due to issues with their upstream provider. The incident caused significant delays in email processing and automations as the system worked through backlogs during recovery. All services were gradually restored, with email sending and automations returning to normal processing times first, followed by landing pages, and finally websites.
We are currently investigating reports of MailerLite connectivity issues. Our engineering team is looking into the root cause and we will provide an update as soon as more information is available.

We are implementing fixes and monitoring the results. While the system recovers, we are working through a heavy backlog of sendings and automations, so please expect delays in these areas until the queue clears.
