Questions about the DNS lookup
What does a DNS lookup show?
The records a domain publishes: A and AAAA for its addresses, CNAME for aliases, MX for mail, NS for name servers, TXT for text such as SPF, CAA for certificate rules and SOA for the zone itself.
Why do my new records not show yet?
Resolvers keep old answers until their TTL runs out. A changed record can take from a few minutes to a day to show everywhere.
Which records does a cold email domain need?
MX records for replies, an SPF record, a DKIM key and a DMARC record. The Domain health tab checks all four at once.
