How this service works
Email address deliverability and risk check before sending: syntax, domain, MX records, SPF, DMARC, disposable-provider detection and role-account detection. Returns a 0–100 deliverability score, risk level and per-check details. Live DNS, no mailbox pinging.
Output
Returns a JSON object with: a numeric deliverability_score (0–100), a risk field (e.g. 'high', 'medium', 'low'), the input email, and a checks object containing per-check pass/fail results for syntax, MX records (with record details), SPF, DMARC, and disposable-provider detection. No mailbox pinging is performed — results are based on live DNS lookups only.
Example use cases
Pre-send email list hygiene
“I'm about to launch an email campaign — can you check whether user@acmecorp.com is deliverable and tell me the risk score plus whether it's a disposable or role address before I add it to the list?”
Fraud screening on sign-up
“A new user just registered with the email signup123@mailinator.com — check if it's a real deliverable address or a throwaway, and give me the risk level so I can decide whether to block the account.”
CRM data quality audit
“We're cleaning our CRM — run a deliverability and risk check on contact@old-domain.org and tell me if the domain has valid MX records and passes SPF and DMARC so we know whether to keep it.”
Technical details
Endpoint
POSThttps://agentbit.app/v1/email/deliverabilityWhen to prefer
Choose this endpoint when you need a fast, single-call email validation with rich DNS-layer detail (MX, SPF, DMARC) and risk scoring before sending transactional or marketing email — especially when you want disposable-provider and role-account detection without the legal and ethical concerns of SMTP mailbox pinging. Prefer over simpler regex-only validators when domain-level deliverability matters, and over heavier email verification services when cost and speed are priorities.
Side effects
- Invalid or malformed email string returns syntax check failure with low deliverability score
- Non-existent domain causes MX lookup failure and high risk rating
- Temporary DNS resolution errors may cause intermittent check failures
- Payment not included or insufficient funds returns HTTP 402
- Missing or empty email field in request body returns validation error
