A toolbox for checking and cleaning email — MX, SPF/DMARC, validation and more. Instant, free, no signup.
Check a domain's mail servers (MX records + priority), detect the provider, and grade MX health.
Look up a domain's SPF and DMARC records, see the DMARC policy, and spot misconfigurations.
Verify a single email address in real time — syntax, MX, SMTP probe, catch-all and typo suggestion.
Quickly check whether an email address looks valid and deliverable, free and without signup.
Detect temporary, throwaway and burner email addresses before they reach your CRM.
Estimate how much you save by cleaning your list: ESP costs, recovered deliverability and bounce reduction.
Need to clean a whole list? Upload a CSV to the bulk email cleaner or wire verification into your app with the email verification API.
