Disify vs MailCheck.ai
Disify
A free, keyless REST API that checks an email's syntax, DNS/MX records, whether its domain is disposable or on an allow-list, and whether its mailbox is a role address, returning a single JSON verdict. No signup is required for the core lookup, with paid business accounts available for higher volume.
MailCheck.ai
MailCheck.ai has rebranded to UserCheck, but its original keyless lookup endpoint keeps working unchanged: pass an address and get back disposable, free-provider, MX, and domain-age signals in one JSON response, aimed at blocking throwaway signups. The rebranded product adds a free-to-start paid tier for higher-volume, authenticated use.
