Actual counts may vary as providers update infrastructure. Use the [SPF Checker](/tools/spf-checker/) to verify the exact count for your record after publishing. ## What Happens After You Generate Your SPF Record? **1\. Publish it as a TXT record at your domain apex.** Log into your DNS provider (GoDaddy, Cloudflare, Namecheap, AWS Route 53, etc.), create a new TXT record with `@` as the host, and paste the generated SPF string as the value. **2\. Verify it with our [free SPF checker](/tools/spf-checker/).** After DNS propagation (typically 5-60 minutes), run a check to confirm the record is published correctly and the lookup count is under 10. **3\. Monitor it over time.** As you add new email services, the SPF record needs updating. Each new `include:` adds DNS lookups. When you approach the [10-lookup limit](/spf-too-many-dns-lookups/), use [AutoSPF](/) to flatten or switch to macros. Provider Reference ## DNS Lookup Cost by Provider | Provider | Include mechanism | Lookups | | ------------------- | ---------------------------------- | ------- | | Google Workspace | include:\_spf.google.com | 4 | | Microsoft 365 | include:spf.protection.outlook.com | 2 | | SendGrid | include:sendgrid.net | 5 | | Mailchimp | include:servers.mcsv.net | 1 | | Amazon SES | include:amazonses.com | 2 | | Salesforce | include:\_spf.salesforce.com | 2 | | HubSpot | include:spf.hubspot.com | 2 | | Brevo | include:spf.brevo.com | 2 | | Mailgun | include:mailgun.org | 5 | | Zoho Mail | include:zoho.com | 4 | | Postmark | include:spf.mtasv.net | 1 | | SparkPost | include:sparkpostmail.com | 1 | | Custom IP (ip4/ip6) | ip4:x.x.x.x | 0 | Lookup counts are approximate and may change when providers update their infrastructure. Use the [SPF checker](/tools/spf-checker/) for live counts. ## Generated a record that exceeds 10 lookups? AutoSPF automatically flattens your includes and re-scans every 15 minutes. Enterprise SLAs, SSO/SAML, audit logs, and DNS rollback included.

I appreciate that it keeps a log of changes made, which prevents many mistakes. A client's SPF record would have way too many lookups, but AutoSPF makes that problem go away. The length of the SPF record is typically not the issue; it's the amount of lookups in the record that are. AutoSPF "flattens" the record, automatically expanding the defined lookups to IP addresses or ranges. And it auto-updates the record when the un-flattened lookups change. PJ Peter J. President · Small-Business (50 or fewer emp.) ### "Helped us go beyond capacity" > AutoSPF did exactly as described, it helped us get past our 10 lookup limit. Afterwards, we hit another limit regarding overall capacity and when contacted, they quickly provided us with a new solution to eliminate capacity issues entirely going forward, so now we can add as many SPF records as needed. They also provided us with a personalized support video explaining their new method in its entirety using our instance as the example. VU Verified User Financial Services · Mid-Market (51-1000 emp.)
