Improve Email Reputation

It would be nice to have a feature which automatically detects whether an email address that was entered for the contact onto the system is valid or not (whether manually or from other lead sources that are coming into lion desk) I always spell the email address out with the contact to make sure I got it correct, however from online leads; prospect usually enter their email addresses incorrectly by mistake or there are spams. If email address is incorrect, it would be nice to have an auto text set up asking the contact to text their email address. (this would definitely improve email reputation, increase deliverability to make sure future emails are not sent to spam folder) Also if there is no email address on file for that prospect, auto text for the contact to send their email address. If there is no phone number on file, auto email to be sent for the contact to send their email address.
