Use case
Validate recipients, inspect sender domains, check content and links, and avoid technical mistakes before outbound campaigns.
Cold outbound usually fails from a combination of risky recipients, weak domains, suspicious content, and overconfident sending volume.
Use WillItInbox as a QA layer before a sequence, not as a promise that cold mail will land everywhere.
Run bulk validation and suppress invalid or disposable recipients.
Route risky recipients through lower-volume or manual review paths.
Send your actual sequence email to a test inbox and fix findings first.
Workflow
Every use case should define what gets tested, who owns the fix, when to retest, and which WillItInbox surface captures the evidence. That keeps deliverability from becoming a last-minute opinion fight.
Outputs
The result should not only be a score. It should identify the highest-risk findings, the owner, the expected fix, the retest trigger, and the accepted risk if a warning remains.
Track SPF, DKIM, DMARC, MX, TLS, PTR, blocklist drift, ramp guidance, and provider reputation evidence in /domains.
Use /dmarc to label sources, find unknown senders, and move toward enforcement safely.
Use /placement for diagnostic seed testing when placement needs a sample beyond technical scoring.

FAQ
The layers are similar, but priorities differ. SaaS teams protect product reliability, agencies need client-ready evidence, newsletters need pre-send hygiene, and developers need API-safe automation.
