What this is
A guide to resolving the “multiple SPF records” error.
Why it matters
Having more than one SPF record causes validation failures.
What to do
Locate all SPF records in your DNS
Combine them into a single record
Include all sending platforms in one line
Remove duplicate SPF records
Save changes
Example fix
Before:
v=spf1 include:_spf.google.com ~all
v=spf1 include:sendgrid.net ~all
After:
v=spf1 include:_spf.google.com include:sendgrid.net ~all
Expert insight
You can only have ONE SPF record per domain. Everything must be combined.
