Only used to show you where the record goes. Nothing is looked up or stored.

Which services send email for this domain?

Tick every provider that sends mail using your domain in the From address, including your CRM, help desk and invoicing tools.

Comma separated. Use the include value your provider gives you, without the "include:" prefix.

Comma separated. Each one becomes an ip4: mechanism. A CIDR range such as 198.51.100.0/24 is allowed.

Stop checking your DNS by hand. We'll watch it for you.

A silent SPF or DKIM change can quietly send your emails to spam for weeks before anyone notices. Drop your email and we'll alert you the moment something looks off, so you fix it in minutes, not after a deliverability cliff.

Continuous DNS checks
SPF, DKIM, DMARC, MX, NS and major DNSBLs - re-checked automatically.
Email alerts on changes
A clear email the day a record is added, removed or modified - no dashboards to babysit.
Plain-English fixes
Every alert tells you what changed, why it matters, and the exact record to set to fix it.

This free SPF record generator builds a valid SPF TXT record for your domain in seconds. Tick the services that send email on your behalf, such as Google Workspace, Microsoft 365, SendGrid or Amazon SES, add any of your own server IP addresses, choose a fail policy, and copy the finished record. The generator assembles the include mechanisms in the right syntax, counts your DNS lookups against the limit of 10 that receivers enforce, and reminds you that a domain may only publish one SPF record.

Frequently Asked Questions

What should my SPF record include?

Include every service that sends email using your domain in the From address: your mailbox provider, your email marketing platform, and any CRM, help desk or billing tool that sends on your behalf. Each service contributes one include mechanism, and your own mail servers are added as ip4 addresses or an mx mechanism. End the record with -all so unauthorized servers fail, keep total DNS lookups at 10 or fewer, and publish exactly one SPF record at your root domain.
