MX Record vs TXT Record: What Is the Difference?
A practical explanation of the difference between MX and TXT records, and why one controls inbound mail routing while the other usually carries policy or verification data.
MX and TXT records both show up in email troubleshooting, which is probably why people mix them together.
They still do very different jobs.
MX record
MX tells the world where inbound mail for the domain should go.
That is routing.
TXT record
TXT usually carries policy or verification data.
In mail workflows that often means:
- SPF
- DMARC
- verification tokens
That is metadata, not inbound routing.
Why this matters

If the domain is failing SPF/DMARC or ownership verification, TXT becomes more important.
