Melissa's Predictive Accept-All Validation uses proprietary algorithms to analyse historical mailbox activity, domain intelligence and email metadata to predict the likelihood of successful delivery for accept-all email addresses.

Identify Accept-All Mailboxes – Detect domains that accept every email address, regardless of whether the mailbox actually exists.
Predict Deliverability – Each accept-all email receives a Deliverability Confidence Score (DCS) to help prioritise contacts with the highest likelihood of successful delivery.

Syntax Checking and Domain Correction

State of the art fuzzy matching automatically detects and corrects common email syntax errors, domain typos and outdated email providers before validation.

Correcting errors like "gamail.com" to "gmail.com" ensures every email address is verified using the correct domain.

General Syntax Checking - Enforces universally accepted email syntax rules and standardises the email address.
Domain Corrections - Corrects the most common misspelling and typos for popular domain names.
Domain Changes - Corrects outdated domain names belonging to an organisation to their new domain name.
