    We will be updating a central piece of SMTP software in Heysender. This will result in a downtime on the incoming SMTP service lasting a few minutes where the SMTP service will not respond to connection requests. Afterwards, the incoming SMTP service will be running but all outgoing e-mail will be caught and saved for later delivery while we update the software.

    The date and time of the update is:

    Tuesday 21st of January 2025 from 20:45 CET to 22:45 CET

    We expect the entire process to take 1-2 hours from start to end. For the first few minutes no incoming SMTP requests will succeed and afterwards there will be a delay of up to 2 hours on outgoing e-mail.

    If you have any questions regarding the update please do not hesitate to get in touch with support.

Issue with logging

    We are currently experiencing e-mails with logging in Heysender. Our hosting partner is updating a key part of their infrastructure which we use to store log files making us unable to handle the logs. We have made a change to the system so we bypass logging of text and HTML versions which solves the issue for now. We will update when all is back to normal.

Issue with webhooks

    Due to a change in the service some webhooks changed format. This has resulted in issues with integrations parsing the webhooks. The change has been rolled back and we're working on fixing the format before we retry the webhooks with the right format.

    If your service responds with 200 OK when a webhook is received we will not retry the webhook. Get in touch with support if you need assistance receiving the webhooks again.
