Email Deliverability Score API — Predict Bounce Risk Before Sending
Get a comprehensive deliverability score for any email address. Combines syntax, MX, disposable, role, and typosquat checks into a single confidence metric.
What is Email Deliverability Scoring?
Deliverability scoring combines all email validation checks into a single 0-1 confidence score. The API considers syntax validity, MX record existence, disposable domain status, role account detection, typosquat risks, and free email classification to produce an aggregate metric.
How to Interpret Scores
Scores ≥ 0.9: Highly deliverable. 0.7-0.9: Likely deliverable but verify. 0.5-0.7: Risky — proceed with caution. < 0.5: Almost certainly undeliverable. Each score includes breakdown flags so you can see which checks triggered.
