Use case

For agencies auditing client deliverability.

Run consistent email deliverability audits, validate client lists, monitor domains, inspect DMARC reports, and produce clearer fix lists.

A repeatable client audit stack

Agencies need consistent evidence, not one-off screenshots. WillItInbox lets teams test messages, validate lists, inspect domains, and explain fixes in a common language.

  • Run real-message tests from each client sending system.
  • Validate sample or full lists before campaign launches.
  • Monitor domain and DMARC health after implementation.

Client-facing outcomes

The highest-value deliverability work is making invisible failures obvious and prioritized.

Technical report

Show SPF, DKIM, DMARC, DNS, header, content, and link findings.

List risk

Quantify invalid, risky, catch-all, disposable, role, and unknown recipients.

Domain health

Track whether fixes hold after DNS and ESP changes.
