Valimail Instant SPF Enables One Click
Valimail
Instant SPF turns email authentication from DNS plumbing into application software. Instead of asking IT to edit a fragile text record every time marketing adds a new email tool, Valimail has customers point SPF to its service once, then approve senders in the product UI while Valimail returns a tailored SPF response for each check using SPF macros. That matters because standard SPF checks are capped at 10 DNS lookups, and going over that can break authentication.

In practice, the pain comes from companies using many outside senders at once, like Salesforce, HubSpot, Zendesk, and payroll or ticketing tools. Each one often adds SPF includes, so the record becomes hard to maintain and can silently fail when it crosses the lookup cap.
-
This is a product wedge, not just a technical feature. Valimail grew to about 65,000 customers by 2024, and its low average revenue per customer, about $460, shows it is selling a narrow, automated workflow that large suite vendors often treat as a bundled checkbox inside broader email security products.
-
The competitive contrast is concrete. Proofpoint and Mimecast sell much broader email security stacks with ARPC in the $10,000 to $20,000 range, while 40% of Valimail customers still pay for Proofpoint and use Valimail specifically for DMARC and SPF management. That suggests better workflow beats broader bundling for this job.
As mailbox providers keep tightening sender requirements, the winning products will be the ones that make authentication feel like flipping permissions on and off, not editing DNS by hand. That pushes the category toward automated control planes, and gives Valimail room to expand from DMARC setup into day to day sender management and deliverability infrastructure.
