Email Notifications if there is a jump in delivered emails
I use Mailgun for transactional emails for a ton of domains. There was 1 domain that recently caused an issue where a ton of spam submissions started being sent through one of the forms on a website. The account lock could have easily been avoided if there was some type of email notification system in place.
This issue with 1 domain caused Mailgun to block our account, and then triggered a series of requirements to get the account unblocked:
1 - Reset your Mailgun account password that you use to login to the control panel. This one is fine and easy.
2 - Enable 2 Factor Authentication for users. This is another item that is relatively easy to get setup.
3 - Reset your Mailgun API key.
4 - Reset your SMTP credentials for each domain on the account.
Requirements 3 & 4 are extremely time-consuming, especially when you are managing a ton of domains.
So - it would be extremely helpful to have some type of email notification system in place where IF there is a domain in your account that starts to show a significant increase in deliveries (like 5,000% in my example), then send the account owner an email so they can look into the issue.
