Why are emails to new email addresses I just set-up still bouncing?

If emails to new accounts are bouncing, first check that the address is correct and that the account exists.

NB - Our MX caches valid and invalid email addresses for performance reasons. If you tried to send an email to the new account before the account was created, our MX cache will have remembered that the address is invalid and doesn’t exist. Normally the cache will expire in 30-60 minutes so please wait and try emailing again once this time has passed.
