The step that prevents email disasters.
WHY THIS MATTERS
DNS records do not travel with your website.
Change nameservers without recording them and mail stops immediately.
WHAT TO RECORD
A records for the domain, www and every subdomain MX records, with priorities
TXT records: SPF, DKIM, DMARC, and any verification records
CNAME records Any other record present
HOW TO RECORD THEM
Export the zone if your provider allows it.
Otherwise, screenshot or copy every record from the DNS panel.
THE VERIFICATION RECORDS
Search Console, business profiles, payment gateways, email services.
These are the ones most often lost, and the loss is silent until verification lapses weeks later.
WHAT TO NOTE ABOUT MAIL
Where mail currently goes. If it is elsewhere, those records must be recreated exactly.
BEFORE YOU CHANGE ANYTHING
Have this record in a document you can reach.
Ten minutes now prevents hours later.
