Please provide an Email alternative to send a Code or verification/activate not SMS only.
Like in the email option, I can choose NOT to have my email published but use an alternative email. It would help if you can ask for a number to publish, and on verification and activation ask for a number to send the verification code. This way I will not have my cell number published on the ad, as I do not want responses to the ad flooding my cell number.

Hi,
Thanks for writing.
We already have this feature. We request the phone number to confirm it however providing it as a contact number is optional.
Thanks,
Jim
