Mailgun have been experiencing intermittent issues with their API. This means that some emails have been unable to send and have remained queued. This will only have affected a small subset Vero customers using our internal systems or the Mailgun integration.
Mailgun have implemented a fix which should ensure all future emails will send without issue and we are currently re-queueing all affected emails. This will result in some emails having been delayed.
If you have any questions about your campaigns please don't hesitate to email firstname.lastname@example.org
