EmailKit is an email verification platform that checks whether email addresses are valid and can receive messages. It helps businesses clean their email lists, reduce bounce rates, and protect their sender reputation.
When you submit an email address to EmailKit, we perform a series of checks without sending an actual email:
Syntax check — We verify the email is properly formatted (has an @ sign, valid characters, etc.)
DNS lookup — We check that the domain (the part after @) exists and has valid DNS records
MX record check — We verify that the domain has mail exchange (MX) servers configured to receive email
SMTP verification — We connect to the mail server and check whether the specific mailbox exists, without delivering a message
Additional checks — We detect disposable email providers, role-based addresses (info@, admin@), and catch-all domains
This entire process happens in seconds and returns a clear status: deliverable, undeliverable, risky, or unknown.
