We have scheduled maintenance on Thursday, July 23rd, 2026 from 7:00 PM to 2:00 AM CEST.
During this window, the following will be affected: • Address book functionality will be unavailable during the maintenance window. • Sending and scheduling of emails and campaigns will not be possible during the maintenance window. • Some accounts may still be able to send emails during the first couple of hours of the window, though this cannot be guaranteed for all accounts.
After maintenance completes, queued emails will be automatically retried — please expect possible delivery delays or send failures. Campaigns scheduled during this window will not be automatically resent.
We recommend completing all email and campaign sends/scheduling before 7:00 PM CEST on July 23rd. We’re carrying out this maintenance to improve the reliability and performance of our platform. We apologize for any inconvenience and thank you for your patience. Posted on
