Personally contacting volunteers more than doubled RSVP and attendance rates over sending just emails. Personally contacting volunteers increased RSVP rates by 168% and attendance rates by 177% over just sending emails asking people to come. Our findings indicate that giving volunteers a call and leaving a voicemail, giving them a call plus sending them a text, and just sending them a text are all superior means of communication over just sending an email if you want people to RSVP and then show up to your team activity!
