Validation engine
JUST checking
an @ symbol.
A valid email format doesn't mean the address is deliverable, useful or safe to accept. IEV checks the address, its domain, its mail infrastructure and known sender intelligence.
Domain & DNS
Check whether the domain exists and whether its DNS configuration supports email delivery.
MX checking
Find the mail exchange servers responsible for receiving messages for the domain.
SMTP verification
Check mailbox-level signals through the receiving mail server without sending an actual email.
Disposable detection
Detect temporary and throwaway email addresses commonly used for unwanted signups and low-quality submissions.
Catch-all detection
Identify domains that accept mail for addresses that may not have an individually verifiable mailbox.
Role detection
Flag shared addresses such as info@, sales@, support@ and admin@.
Typo & gibberish detection
Identify suspicious or malformed addresses and common domain mistakes before they become bad data.
Risk signals
Combine technical validation with sender intelligence to identify addresses that deserve extra attention.

Sender intelligence
Don't just check the mailbox.
Some addresses can pass basic technical checks and still be unwanted. IEV checks the address against a database containing more than 1 million spam, junk, scam and phishing sender records.
This gives your application another signal when deciding whether an address should be accepted, flagged or rejected.
Spam sender detectionIdentify known spam-related sender records.
Scam & phishing signalsCheck against known problematic sender records.
Junk sender intelligenceFilter addresses associated with unwanted traffic.
Shopify-focused protectionUseful for stores receiving public form submissions.
