VSys One has a built-in word processor and mail merge engine which you can use to send printed letters and e-mails to your volunteers. VSys merges your templates with each volunteer's data, and then keeps a record of all communications sent so you can go back and reference it later or re-send letters as needed.
Every letter has a Letter type and is created using a Letter template. You can also post "empty" letters (not created in VSys), for example using VSys to print the mailing labels for your newsletter and then track who was sent the newsletter.
Letters can be printed, e-mailed, or viewed on the kiosk.
