Suped

SPF flattening service for the 10 lookup limit

Use Suped as your SPF flattening product: one hosted SPF include, every sender flattened, IP ranges kept current, and new senders added without touching DNS again.

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.

  • 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

Suped serves every IP range your senders use, flattened into one include. Add new senders from the dashboard, the record updates itself.

Automated SPF flattening that stays current

SPF flattening service
SPF has a hard cap of 10 DNS lookups. Cross it and receivers can treat legitimate mail as failed authentication. Suped flattens every sender behind one hosted include and refreshes sender IP ranges automatically, so the lookup ceiling stops being a weekly DNS firefight.

Add every new sender from one dashboard

Hosted SPF delivery
Marketing adds a new ESP, support changes helpdesks, finance adds a transactional tool. With Suped, those are sender management changes in the dashboard, not TXT edits in a DNS provider.

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.

What an SPF flattening product should do

SPF flattening is not a static copy and paste job. A real product needs live sender management, validation, and hosted delivery so your record does not drift out of date.

v=spf1 include:abc.spf...
One hosted include
Publish one SPF include to Suped. Every future sender lives behind that include instead of inside your DNS zone.

Hosted SPF stays under the cap
Lookup count stays low
Suped resolves nested includes and serves the flattened result through hosted SPF, keeping SPF evaluation below the hard limit.

IP ranges stay current
When a sender changes its outgoing IP ranges, Suped refreshes the flattened result behind the hosted include.
Desired SPF
v=spf1 include:sender.example ~all
Syntax checked before save
Validated before save
Desired SPF records are checked before they are flattened, so bad syntax is caught before mailbox providers see it.
