100% free
It’s an SPF record generator that lets you create a working SPF record with a few clicks at most.
Just click on the email service providers you will send emails with, and the record will pop up in the field on the right.
Then, it’s up to you to add the SPF record to your domain’s DNS settings.(We’ll help you with that, too. Promise…)
Instead, it stands for Sender Policy Framework.
In simple terms, it allows you to specify what servers can send email on behalf of your domain.
Here’s how it works:
Say you only use Gmail to send emails. In that case, you’d only have Gmail’s server in your SPF record.
It would look something like this:
v=spf1 include:_spf.google.com ~all
Receiving servers check your SPF record whenever an incoming email claims to be coming from your domain. If the email does not come from an authorized server it will fail authentication.
In the example above, it means that if emails claim your domain as the sender but they’re not coming from this particular Google server, they will fail SPF authentication.
The email may then get sent to the spam folder or not get delivered at all.
Click on the email services you use to send emails and your SPF record will appear on the right.

SPF generator FAQ
How many times can I use the SPF generator?
You can use it as many times as you need.
Can I add multiple providers to my SPF record?
Yes, just click all the email service providers you send email with.
Do you have generators for other email authentication protocols?
Yes, we have a DMARC generator too.
What happens to an email if it fails SPF authentication?
You can decide what happens to them by setting up a valid DMARC record. Receiving servers will typically follow the policy you set in your DMARC record. DMARC's three main policies are None (email gets a pass), Quarantine (email gets sent to spam), and Reject (email won't get delivered at all).
What happens if I send from a service not included in my SPF record?
Your emails will fail authentication and likely get sent to spam or not get delivered at all.
