About this TXT Lookup tool
TXT records carry email authentication policies and ownership-verification strings. CheckHub fetches every TXT record and labels SPF, DKIM, DMARC, and common provider tokens for you.
How to use the TXT Lookup
- Step 1. Enter a domain.
- Step 2. Read each TXT record with its detected purpose (SPF, DKIM, DMARC, or verification).
Frequently asked questions
- How many TXT records can a domain have?
- A domain can have many TXT records but only one SPF and one DMARC record at the apex. Multiple SPF records cause mail authentication to fail.
