Blocked accounts


New Email
I have a couple of accounts on and I use it for business.
I've read about several blocked accounts.
I would like to know in what cases blocks an account.
Thank you.


Customer Service
We don't know for sure but usually it's for at least one of the following reasons which they view as a red flag:

sending more email than usual- If you normally send roughly 10 emails a day and all of a sudden send out 100, they may block you.

sending too many emails to invalid email addresses

logging in from improbable locations in a short amount of time (logging in from the US and then a short time later logging in from Africa etc)
