I used to be able to pull customer email addresses by their birthday month. This was to send out our birthday coupons. This feature seems to no longer exist in CheckIn Pro. I was able to go to Customers>Find>Search Field: Birthdays = [month], Search field 2: Emails = *
We send these monthly, at the end of the month for the next month. This is a super important feature for us that we will need to utilize again next week.
