From Volunteers, choose Email volunteers. Send to selected profiles or choose a group: All Volunteers, Volunteers with upcoming assignments, or Volunteers with no upcoming assignments. You can also choose Email Volunteer from one profile.
Review the candidate and unique-email counts plus any exclusions. Archived profiles are excluded from broad audiences; a deliberately selected archived profile requires explicit confirmation. Sends to 100 or more unique recipients require the large-audience checkbox.
Add a subject, message, and optional approved attachments, then send. If the audience changes before send, review the refreshed preview. Use History to open the preserved message and recipient record.
