Finding the right balance when communicating with volunteers through email can be challenging. To manage your email frequency and timing, consider relevance, frequency, and timing. Only send emails that are relevant and useful to your volunteer, and segment your email list according to their roles, interests, or preferences. Avoid sending too many emails that may clutter your volunteer's inbox or reduce their attention. Establish a regular schedule or a newsletter for your email communication and stick to it. When sending an extra email, explain why and how it differs from your usual communication. Additionally, choose the best time to send your email based on your volunteer's availability and responsiveness. Avoid sending emails at odd hours or on weekends or holidays, unless it is urgent or necessary. By testing different times and days, you can determine what works best for your volunteer and improve your communication with them in order to build a stronger and more productive relationship.
