When printing mailing labels or envelopes, it makes sense to exclude those who have an E-mail address if you're using E-mail when possible and only mailing hard copies if necessary.

You can use an expression in the Filter that will only include those without the '@' character in the E-mail address field, which effectively excludes any with an E-mail address.

For instance if you're in Reports / Customer Mailing labels....

Click on Reservation Filtering..., then the "Advanced Condition Expression..." button, and enter this expression exactly:

 Find(Cust:Cust_Email,"@") = 0

Note that this will be combined with any other reservation filtering selected.

Click Save / OK... and make sure "Use reservations, with optional filtering" is selected (this won't work for customers without reservations).

Now the list should only include people without any E-mail address.

Similarly, to do the filtering when printing reservation receipts.... once you get to Print Reservation Receipts (either through Reports or from right-clicking on a tab view, Print or E-mail for All shown, etc..)... then click "Filtering..." and enter an Advanced Condition Expression as shown above.
