Fake users break your product
VerifyKit ensures every email is real before it reaches your database.
Disposable emails
Temporary inboxes used to bypass your signup. Gone in minutes, your data is polluted forever.
Bot signups
Bots create accounts using throwaway and unreachable addresses, inflating your user count with garbage.

No verification
Without OTP or verification, anyone can claim any email. No proof the user is who they say.
