We had the same problem some months ago with Mailgun. They blocked our account after many years using them without apparent reason or prior notice and took them 2 days to unblock it, leaving our thousands of clients stranded without receiving any of our transactional emails.

Lesson learnt, always keep a backup for crucial services and move away from Mailgun

We just moved to Mailgun because SendGrid did something similar to us! Fortunately we only used SMTP so it was a straightforward change, but having a backup for something like Twilio Video would be quite an effort.
