Acquiring a new shul member is estimated to cost 5-7 times more than retaining an existing one. Yet most synagogues invest heavily in programming and outreach while doing almost nothing systematic to keep current members connected between the High Holidays. Email is your most cost-effective tool for year-round member engagement and retention. Here’s how to use it strategically.
Why Members Leave (And How Email Helps)
Exit surveys from synagogues consistently show the same reasons members lapse:
- “We felt disconnected from the community”
- “We didn’t know about events and programs until it was too late”
- “No one noticed when we stopped coming”
- “The shul never communicated with us unless they wanted money”
A well-run email program directly addresses every one of these. Consistent communication makes members feel connected even when they’re not in the building. Timely event announcements ensure members know about programming while there’s still time to participate. Engagement touchpoints replace the silence between appeals.
The Member Email Journey: From New Member to Lifelong Mainstay
Phase 1: New Member Onboarding (Months 1-3)
The first 90 days are critical. A new family is still deciding whether this is their community. Your email program should actively welcome them and introduce them to what your shul offers.
Email 1 (Day 1-2 after joining): Personal welcome from the Rav. Not a form letter — a genuine, warm message that references why they joined if you know, and extends an invitation to connect. Include the Rav’s direct contact information.
Email 2 (Week 1): “Getting to know us” — a practical guide to the shul. Davening times, where to find the schedule, how to join the Shabbos morning Kiddush group, who to contact for different needs. Make it easy to participate.
Email 3 (Week 3): Invitation to a low-barrier entry event — a shiur, a Shabbos Kiddush, a community learning program. Something that requires minimal commitment but creates a social connection.
Email 4 (Month 2): Introduction to community resources — the gemach, the chavrusah matching program, the women’s learning group, the youth program. Not a sales pitch — a genuine “here’s what your community has for you.”
Email 5 (Month 3): Check-in. From the membership coordinator or Rav: “It’s been three months since you joined. How are you settling in? Is there anything we can help with?” Personal. Brief. Genuine.
Phase 2: Ongoing Engagement (Months 4-24)
After the onboarding sequence, shift to your regular member communication cadence:
- Weekly newsletter: Zmanim, Dvar Torah, announcements, one call to action. The backbone of your email program.
- Monthly community update: Longer-form content — a feature on a new program, a spotlight on a community member, news from the Rav. Build community feeling.
- Event invitations: Sent 3 weeks and 1 week before each event. Not everything to everyone — segment by interest where possible.
- Personal milestones: Automated birthday or anniversary emails from the Rav are powerful. “Wishing you a heartfelt mazal tov on your anniversary — may this year be filled with bracha.” Low effort, high impact.
Phase 3: Lapsed Member Re-Engagement
Members who haven’t engaged in 6+ months — haven’t opened emails, haven’t attended events, haven’t donated — need a different approach than your regular list.
Re-engagement sequence (3 emails, 2 weeks apart):
- “We miss you” — a personal note from the Rav or gabbai, no ask, just genuine outreach
- “Here’s what’s new at [Shul name]” — highlight recent developments, new shiurim, changes to programming
- “Is there anything we can do better?” — a genuine request for feedback. This email often generates more responses than any other.
Members who don’t engage with the re-engagement sequence should be moved to a low-frequency track (major holidays only) rather than removed entirely — they may re-engage when their life situation changes.
Segmentation Strategies for Shul Email
Not every member should receive every email. Smart segmentation improves engagement and reduces fatigue:
- By gender: Men’s and women’s programming announcements go to the relevant audiences only
- By age/family stage: Youth programming to families with children; senior programming to older members
- By donation history: Major donors receive more personalized communication from the Rav directly
- By engagement level: Highly engaged members can receive more frequent communication; lapsed members receive less
- By neighborhood: For large kehillos with geographically dispersed members
The Annual Member Communication Calendar
Plan your full-year email calendar in advance:
- Elul–Tishrei: High Holiday schedule, seating, campaign, sukkos programming
- Cheshvan: Post-Yom Tov programming restart, new shiurim announcements
- Kislev: Chanukah programming, Chanukah campaign
- Tevet–Shvat: Winter programming, Tu B’Shvat content
- Adar: Purim programming, Matanos L’Evyonim campaign, Purim party
- Nissan: Pesach schedule, Maos Chitim campaign, pre-Pesach content
- Iyar–Sivan: Lag B’Omer, Shavuos, end-of-year programming
- Summer: Camp recommendations, summer shiurim, back-to-Elul preview
Metrics That Matter for Shul Retention Email
Track these KPIs to understand if your email program is working:
- Newsletter open rate: Target 40-55% (community emails significantly outperform commercial)
- Event registration rate: What percentage of event email recipients actually register
- Membership renewal rate: Track year-over-year to correlate email engagement with retention
- Reactivation rate: What percentage of lapsed members re-engage after your re-engagement sequence
Technical Considerations: Filter Compatibility
For Orthodox communities, ensuring your emails reach filtered inboxes is essential. KosherEmail’s platform is designed to deliver to members using NetFree, Rimon, and other kosher filtering services — so your welcome email, your weekly newsletter, and your membership renewal notice all arrive intact for every member.
