Forms and onboarding
Check whether an email address and its domain look usable before a signup or onboarding record enters your workflow.
FormatDock Pro Reference
Email and domain checks for cleaner contact data
FormatDock Pro helps you check email addresses and domains before using them in signups, outreach, imports, or contact workflows.
Start with three Pro endpoints for email analysis, domain checks, and batch validation.
Best Fit
Where the first Pro release helps most
These checks are most useful when a bad email address or weak domain setup can cause problems in a signup flow, CRM import, or review queue.
Existing contact data
Review older records when you need a compact technical check instead of manually chaining DNS lookups.
List-sized work
Use the batch route when single-email checks are too awkward for a cleanup pass before sync or outreach.
Headline Pro endpoints
The first public paid routes
These three routes cover the main tasks most teams want first: checking one email, checking one domain, or validating a list in one pass.
Analyze one email address
Check syntax, disposable or role-like patterns, and the destination domain's mail posture in one request.
https://api.formatdock.com/v1/tools/email/analyze
- Best when one mailbox needs a faster yes, no, or review decision.
- Useful for signups, contact intake, CRM cleanup, and lead screening.
Inspect one domain's mail setup
Resolve MX, SPF, DMARC, MTA-STS, TLS-RPT, and BIMI signals without stitching together your own DNS checks.
https://api.formatdock.com/v1/tools/domain/analyze
- Best when one domain needs a compact technical posture check.
- Useful for intake review, technical checks, and mail-domain inspection.
Batch-validate email lists
Validate and classify a newline-separated email list when single-email checks are too slow or awkward.
https://api.formatdock.com/v1/tools/email/batch-validate
- Best when the job is import-sized rather than single-record.
- Useful for cleanup passes before a CRM sync or list review.
Boundaries
What these checks do and do not cover
FormatDock Pro is designed to surface useful technical signals around mailbox and domain quality. It is not positioned as a guarantee of deliverability, identity, or compliance.
No guaranteed inbox placement
Clean posture signals are not a promise that a real message will be delivered or welcomed.
Not a fraud or identity product
These endpoints help with operational checks and hygiene, not full identity assurance or abuse scoring.
No legal or compliance advice
The results are technical and reference-oriented. They should not be presented as compliance or legal advice.
