DuoCircle AutoSPF vs. Valimail
If you’ve researched SPF flattening or automatic SPF management, you’ve probably seen Valimail. They’re the original major name in the category, with deeper enterprise products that go beyond SPF into broader DMARC and email-authentication management.
DuoCircle AutoSPF exists specifically because of Valimail. Here’s that story, then the honest comparison.
The origin
In the early years of DuoCircle’s outbound SMTP service, customers were breaking their SPF records due to the structure of AWS-hosted senders: too many include: references, too many DNS lookups, the 10-lookup limit blown and SPF failing for legitimate mail. We needed an SPF flattening solution and approached Valimail about a partnership.
Two or three sales calls in, Valimail quoted $1,000 per month to fix the problem for one of our customers. That customer was paying us $4 per month. The math didn’t work for anyone except Valimail.
So DuoCircle built AutoSPF instead. It now runs for a $16 billion IT services firm and tens of thousands of smaller organizations, all of which would have been priced out of the Valimail solution.
What DuoCircle AutoSPF covers
- Automatic SPF management that keeps you under the 10-DNS-lookup limit by flattening included senders into a single record DuoCircle hosts and updates
- Continuous monitoring of upstream sender changes (e.g., Google Workspace updating its SPF includes) with automatic propagation
- Alerting and reporting when sender changes affect your authentication posture
- Volume-based pricing designed to work for SMB through enterprise
What Valimail covers that AutoSPF doesn’t
- Broader DMARC and email-authentication suite (Valimail Enforce, Valimail Monitor) beyond SPF specifically. AutoSPF is focused; Valimail covers more of the email-authentication stack as one product family.
- Enterprise-tier vendor relationships with named delivery teams and dedicated CSMs at the largest customer tiers.
- Specific ecosystem integrations with major sending platforms that have direct partnerships with Valimail.
Pricing comparison
- Valimail pricing is enterprise-tier for the broader suite. Their free DMARC Monitor product exists, but the SPF and full DMARC enforcement products are gated behind sales conversations and priced for organizations with budget for tier-one vendor commit.
- DuoCircle AutoSPF pricing is on the product site, scales with sender complexity rather than firm size, and is dramatically less expensive than Valimail’s enterprise tiers. The 90/50 framing (about half the cost for the same SPF capability) understates the gap at smaller customer tiers, where AutoSPF can be running for under $5 per month while Valimail wouldn’t engage at any price.
