FAQ
Does this confirm the email inbox exists?
No. Format validation cannot guarantee deliverability. Use verification emails or provider checks for that.
Should I use strict RFC validation?
Strict RFC rules allow unusual addresses. Many products prefer a pragmatic validator for real-world addresses.
