SPF flattening service for the 10 lookup limit
Add senders from the dashboard,
never edit SPF again
Publish one include that points at Suped. As your sender list changes, Suped flattens everything into two lookups so the 10-lookup ceiling stops being your problem.
What is SPF flattening?
SPF record flattening takes a record full of includes, resolves those includes into IP ranges, and serves the result without forcing mailbox providers to chase every nested DNS lookup.
Hosted SPF is how Suped delivers it. You publish one include to Suped, then manage every sender from the dashboard while Suped keeps the flattened record current behind that include. If you want the mechanics behind common failures, review the SPF lookup limit and SPF TXT formatting guide.
- Resolve nested includes into sender IP ranges
- Serve the result through one hosted SPF include
- Stay below the 10 lookup limit as new tools are added
- Refresh sender IP ranges when providers rotate them
- Move future sender changes out of DNS
Automated SPF flattening that stays current
Add every new sender from one dashboard
SPF flattening service, delivered through hosted SPF
Manual SPF record flattening only helps until the next sender changes its IPs. Suped pairs flattening with hosted SPF so the record stays current without another DNS edit.
