We use 5x7 postcards for recall and reactivation.
It has a lot of space for text, but OD Recall manager doesn't allow a big enough text box.
Is the postcard a sheet that can be customized someplace? I haven't been able to find it.

Re: Customizing Recall Postcards
There are a few adjustments you can make for postcards under Setup -> Appointments -> Recall. In the Postcards per Sheet field, entering "1" will fit the postcard to a 5x7 size. You can also adjust the margins for the postcard in this window.
