SPF Record Generator

Create a correct SPF record for your domain: specify allowed IPs and services.

Create an SPF record for a domain

The generator builds a correct SPF record from your data: specify the IPs of your own mail servers, add includes for services (e.g. _spf.google.com for Google Workspace or spf.protection.outlook.com for Microsoft 365) and choose a policy for the rest of the world. Copy the ready string in one click.

Add the resulting record to the domain DNS as a TXT record for the root (@). Remember the key rules: there must be only one SPF record, at most 10 DNS lookups (each include counts), and start with the soft ~all policy, moving to -all after verifying all your mail passes.

FAQ

How to create an SPF record?
Specify your mail server IPs and services (e.g. include:_spf.google.com for Gmail), choose a policy for the rest — the generator builds a ready string.
Where to add the SPF record?
In your domain DNS control panel as a TXT record for the domain root (@). The value is the generated string starting with v=spf1.
What to put in include?
Domains of mail services that send your mail: _spf.google.com (Google), spf.protection.outlook.com (Microsoft), etc. Your provider gives them.
How long does a change take?
After adding the TXT record, changes propagate in DNS from a few minutes to 24-48 hours due to caching.
