When you cannot receive mail.
WHY IT MATTERS
For many businesses, losing email is worse than losing the website.
Enquiries stop arriving and you do not know.
WHAT CAN CAUSE IT
A domain problem A hosting problem A full mailbox A blacklisting A configuration change
THE FULL MAILBOX PROBLEM
Mail is rejected and senders receive a failure.
Silent from your side.
Monitor mailbox usage.
WHAT TO ARRANGE
An alternative contact method customers know about A phone number and WhatsApp on your site Someone who can tell customers if email fails
WHAT TO KEEP INDEPENDENT
At least one email address not on your own domain, for account recovery and emergencies.
WHAT TO MONITOR
That mail is arriving. A day with no email is a warning.
WHAT TO BACK UP
Mailbox contents, if important.
Mail on a server is not backed up unless you back it up.
WHAT TO TEST
Sending to and from your addresses, periodically.
