SPF record setup guides by provider

Provider-specific SPF setup guides — the exact include to add, its DNS lookup cost, and how to keep the combined record under the 10-lookup limit.

Include: include:spf.protection.outlook.com · ~1 lookup(s).

Include: include:_spf.google.com · ~3–4 lookup(s).

Include: include:secureserver.net · ~3 lookup(s).

Include: include:sendgrid.net · ~1 lookup(s).

Include: include:servers.mcsv.net · ~1 lookup(s).

Include: include:_spf.salesforce.com · ~1 lookup(s).

Include: include:amazonses.com · ~1 lookup(s).

Include: include:spf.protection.outlook.com · ~1 lookup(s).

Include: include:_spf.mx.cloudflare.net · ~1 lookup(s).

Adding several of these to one domain is the classic route to a too-many-lookups permerror. If you stack providers, plan to flatten or use a macro.

Frequently asked questions

How do I set up an SPF record for my provider?

Add your provider’s include to your single SPF record and end it with ~all or -all. Pick your provider above for the exact value and lookup cost.

What if I use several providers at once?

Combine every include into one record, then check the total lookup count. If it exceeds 10, flatten the record or move to a single-lookup macro.
