The “Extraction Blacklists” tab allows you to tell Apptoto what email addresses and phone numbers to avoid extracting from appointments.
This can be useful if an email address or phone number often shows up in your appointments (e.g., your phone number or email address).
You can also blacklist an entire domain of email addresses by adding @yourcompany.com to the blacklist.
They also prevent Apptoto from sending messages to those email addresses and phone numbers. So if you add an email address or phone number to one of these lists, and then manually add that same email address or phone number to an appointment, Apptoto will not send messages to it.
These lists do not prevent Apptoto from sending notifications (on the ‘Tools’ > ‘Notifications’ tab).
