Wondering if it would be possible to build new reminder notification options. Right now, if we want to send automatic reminders to our one-time volunteers, all our on-going volunteers also have to receive the reminder emails--there isn't a way to make a distinction between on-going and one-time volunteers. It would be great if we could have the option to set up automatic emails for one-time volunteers. 

We get a lot of complaints from on-going volunteers, and they also told us they start to ignore all the emails they receive from the site. But, they don't want to turn off their notifications completely, just in case. 

Thank you!
