Identify email hosting
Find out where mailboxes are hosted and which provider manages them. Moving a website does not automatically move email accounts.
Review DNS records
Website, email and verification records can coexist at the domain. Record the current setup before an authorised person changes it.
Test after a change
Check website access, inbound email, outbound email and form notifications. Use real inbox checks; a website saying “sent” is not proof of receipt.
Keep the previous details
Retain a record of the old settings until the move is accepted. Agree who can reverse a change if the test fails.
