Follow the steps to create a customized SPF record for your domain

Let's get started!

Please provide the domain for which you'd like to generate an SPF record

Email Security

What is SPF and why is it important?

SPF (Sender Policy Framework) is an email authentication method that defines which mail servers are allowed to send emails on behalf of your domain.

When an email is received, the recipient's server checks your SPF record to verify whether the sending IP or service is authorized. If it's not listed, the email may be marked as spam or rejected.

Without a properly configured SPF record, your domain is vulnerable to:

Email spoofing and impersonation

Poor inbox placement

Higher bounce and spam complaint rates

Next Steps

What to do after generating your SPF record

After generating your SPF record, follow these steps to activate it correctly

Step One

Add the SPF record to DNS

Copy the generated TXT record and add it to your domain's DNS settings.

Important:

Only one SPF record per domain

If you already have an SPF record, merge the values instead of creating a second one.

Step Two

Choose the right policy

Your SPF record usually ends with:

~

~all Recommended

Emails from unlisted servers are accepted but marked. This is the safest option while testing.

-

-all

Emails from unlisted servers are rejected outright. Maximum protection.

Step Three

Test and monitor

Send test emails and verify:

Authentication passes

No legitimate emails blocked

Final Step

Combine SPF with DKIM & DMARC

SPF alone provides basic protection, but combining it with DKIM and DMARC creates a full email authentication system.

DKIM

Verifies message integrity

DMARC

Enforces policy & provides reporting

Together, these protocols significantly improve deliverability and protect your domain from abuse.

FAQs

Frequently Asked Questions

What is an SPF record and why do I need one?

An SPF (Sender Policy Framework) record is a DNS TXT record that specifies which mail servers are authorized to send email on behalf of your domain. It helps prevent spammers from spoofing your domain and improves email deliverability.

What is the difference between -all, ~all, and ?all?

-all (fail) is the strictest policy that rejects unauthorized mail. ~all (softfail) marks unauthorized mail but doesn't reject it, good for testing. ?all (neutral) neither passes nor fails unauthorized mail.

What is the 10 DNS lookup limit?

SPF records are limited to 10 DNS lookups. Each 'include', 'a', 'mx', and 'redirect' mechanism counts toward this limit. Exceeding it can cause SPF validation to fail, so consolidate where possible.

Can I have multiple SPF records?

No. You can only have one SPF record per domain. If you need to authorize multiple services, combine all mechanisms into a single record. Multiple SPF records will cause validation failures.

How do I add the SPF record to my DNS?

Log into your DNS provider, add a new TXT record with hostname '@' (or leave blank) and paste the generated SPF record as the value. If you already have an SPF record, merge the new mechanisms into the existing one.
