SPF Record Generator
Build a valid SPF TXT record for Microsoft 365, Google Workspace, your own mail server and sending services – with a lookup counter.
Build a correct SPF record by ticking the services that send email for your domain – Microsoft 365, Google Workspace, Zoho, SendGrid, Mailgun, Amazon SES, Brevo, Mailchimp – and adding your own servers. The generator keeps the record valid, counts DNS lookups and warns before you go over the limit.
How to publish it
- Tick every service that sends as your domain, including invoicing, CRM and website contact forms.
- Copy the record and create (or replace) a single TXT record at
@in your DNS. - Wait for the TTL, then confirm with the SPF, DKIM & DMARC Checker.
常见问题
Can a domain have two SPF records?
No. Two v=spf1 TXT records make SPF fail with permerror. Merge everything into one record.
