Volunteers disappear during the silence between their shifts. Communication fills those gaps. This lecture teaches you the communication calendar every volunteer program needs — what messages to send, when to send them, through which channels, and how to make them sustainable without burning out your coordinator.
Communication Philosophy
Three principles guide volunteer communication:
1. Consistency matters more than volume: A volunteer who receives a brief text reminder weekly is more engaged than one who gets a fancy monthly email. Frequency and reliability beat elaborate messages.
2. Different channels serve different purposes: Email for formal announcements and detailed information. Text/SMS for quick reminders and urgent info. Slack for peer connection. In-person for relationship-building. Use the right channel for the message.
3. Communication should be templated and automated where possible: If sending a message requires custom writing every time, it won't happen consistently. Templates and automation ensure good communication even during busy periods.
The Volunteer Communication Calendar
| Timing | Message Type | Channel | Content | Time to Send |
|---|---|---|---|---|
| 1 week before shift | Shift reminder + context | Email or SMS | "Hi Sarah! Excited to have you volunteering on Tuesday 10am-12pm. We're processing donor thank-yous this week. Bring a pen. Park in lot B. Questions? Email me." | 15 min |
| 24 hours before shift | Reminder (optional) | SMS | "See you tomorrow at 10am! Lot B. Any questions?" | 5 min |
| Within 24 hours after shift | Thank you + specific feedback | Email or message | "Great work today! You processed 45 thank-yous with perfect formatting. That's huge." | 10 min |
| Weekly | Organizational update | Email or Slack | Org news, volunteer impact, upcoming opportunities | 20 min |
| Monthly | Recognition spotlight | Email + social | Feature one volunteer: story, photo, impact | 30 min |
| Quarterly | Impact report | Aggregate volunteer impact, outcomes enabled, program updates | 30 min | |
| Annually | Year in review + survey | Email + possible call | Celebration of year, request feedback, ask about next year | 45 min |
| When milestone reached | Milestone recognition | Email + possibly social | 50 hours, 100 hours, 1-year anniversary, etc. | 10 min |

Channel Selection Strategy
Email: Formal, detailed, archived. Use for: shift reminders, impact reports, program announcements, detailed feedback or coaching.
Text/SMS: Immediate, personal, intrusive if overused. Use for: shift reminders (24 hours before), emergencies, quick check-ins. Keep to 2-3 texts per month per volunteer.
Slack/WhatsApp: Community, peer-to-peer. Use for: volunteer group discussions, peer support, casual updates, celebrating wins in real-time. Great for virtual volunteers.
Phone call: Relationship-building, problem-solving. Use for: new volunteer onboarding, exit interviews, addressing conflicts, checking on volunteers who've gone silent.
In-person/group event: Connection, visibility. Use for: quarterly all-hands meetings, annual celebration, volunteer milestone parties.
Social media: Public recognition, recruitment. Use for: sharing volunteer stories, announcing volunteer opportunities, recruiting new volunteers.
Frequency Guidelines (Don't Overdo It)
Volunteers should hear from you, but not so often that they mute notifications.
Minimal (keeping people minimally informed):
- Shift reminder (week before)
- Post-shift thank you
- Monthly organizational email
- Total: 3-4 messages/month per volunteer
Standard (what most programs should aim for):
- Shift reminder (week before)
- 24-hour text reminder (optional)
- Post-shift thank you
- Weekly group update (not individual)
- Monthly spotlight or recognition
- Total: 3-5 messages/month per individual volunteer + 1 group message/week
Engaged (for volunteers who are in leadership or very active):
- Weekly individual check-in (10 min call or message)
- Shift reminders and thank yous
- Weekly group updates
- Monthly one-on-one mentoring call
- Total: 5-10 messages/month + monthly call
Building Automation to Make Communication Sustainable
Sustainability is key. You can't manually send a reminder to every volunteer every week. Automate where possible:
Scheduling emails: Most email platforms (Gmail, Mailchimp, Constant Contact) allow you to schedule emails. Create your weekly update once, schedule it for 8am Tuesday, and it sends automatically.
SMS reminders: Platforms like Twilio, Remind.com, or SimpleTexting integrate with volunteer management software to auto-send shift reminders.
Templated follow-ups: Create message templates in your email that you can customize with a name and details (2 minutes per message instead of 10).
Volunteer management platforms: Platforms like VolunteerHub or Galaxy Volunteers have built-in communication tools that automate reminders and track communication.
Google Forms → Spreadsheet workflow: Volunteers submit a form confirming their shift; Google Sheets auto-populates their confirmation; you add feedback in a column; a template email merges the feedback and sends automatically.
Measuring Communication Effectiveness
- Email open rate: What % of volunteers open your emails? Target: 40%+
- SMS response rate: What % reply when you text? Target: 60%+
- Shift confirmation rate: What % confirm their shift when reminded? Target: 80%+
- Volunteer engagement survey: "How often do you hear from us? Is it about right, too much, or too little?" Target: "about right" from 70%+
- Volunteer retention impact: Do volunteers who receive more frequent communication stay longer? (Usually yes.)
What to Do Next
Create a one-page communication calendar specific to your program. What messages will you send and when? Pick 3 templates from this lecture and customize them for your organization. Start with just the shift reminder and post-shift thank you. Once you nail those two, add the weekly update. Over time, you'll have a full communication rhythm that feels natural to your organization.
