FAQ
Common questions
What does this free checker do?
It helps you see if an email address looks real and likely to receive mail—useful before you save it in a sign-up form or add it to your list.
Does the person get an email when I check?
No. Nothing is sent to their inbox from this tool. They will not see a notification that you checked their address.
Is the result always 100% accurate?
No tool can promise that for every inbox provider in every situation. We give you our best judgment so you waste fewer bounced messages—but always use common sense.
Can I use this for bulk lists?
This page is meant for occasional checks on addresses you’re allowed to work with. For large lists or automation, use the options your team prefers and follow spam and privacy laws.
