DropMail vs MailCheck.ai
DropMail
A GraphQL API for spinning up ephemeral inboxes and reading their incoming mail over HTTP or a live WebSocket subscription. It now requires a free self-service `af_` token for every request after retiring support for arbitrary legacy tokens.
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.
