Have an email validator tool built into concierge so if someone uses a invalid/spam email they do not have the option to book a meeting.

I use a couple right now that are super valuable:
https://mailtester.ninja/
millionverifier.com

They give 3 results:
1. Valid
2. Uncertain (if they have email security etc.)
3. Invalid

The “invalid” are always invalid, so it would be very valuable to have the option “If Invalid do not show calendar”.

Seems like we could just build our own and not have to use a 3rd party.
