couple of ideas:

A)

• write a cron job that runs every hour to check that an email account is valid or invalid by sending an email to test@example.com
• if the email account is invalid, remove that email account from all campaigns
• if that campaign is active and has just that erronous account and is active, move it to paused
• update the email accounts ui to show working/valid email accounts at the top and invalid ones at the bottom
• on the selector for create/edit campaign only show valid email accounts

B)

open to any other implementations as well
