How to Reach People Who Don’t Check Email: Group Messaging Strategies with SMS, RCS, and WhatsApp

Image for How to Reach People Who Don’t Check Email: Group Messaging Strategies with SMS, RCS, and WhatsApp

Email isn’t dead, but it’s not reaching everyone anymore. Nearly 50% of consumers admit they overlook non-urgent emails, and many people only check their inbox for work or receipts. If your engagement rates are dropping or your audience prefers instant communication, it’s time to expand beyond email.

The solution? Mobile messaging platforms like SMS, RCS, and WhatsApp that deliver 98% open rates and reach people where they actually pay attention—on their phones.

The Email Problem: Why Traditional Communication Falls Short

Regular email checking is no longer universal behavior. For organizations, meetup coordinators, and marketing teams, this creates a critical gap: important updates like event reminders, schedule changes, and time-sensitive alerts often go unseen until it’s too late.

The numbers tell the story:

  • Text messages have a 98% open rate vs. 20% for email
  • 90% of SMS messages are read within 3 minutes
  • Mobile users check their phones 96 times per day

If your audience includes busy professionals, students, or mobile-first users, mobile messaging isn’t optional—it’s essential.

Why SMS, RCS, and WhatsApp Outperform Email

SMS: Universal and Instant

Every phone can receive SMS messages, making it the most accessible option for urgent communications and broad reach.

RCS: The SMS Upgrade

Rich Communication Services adds multimedia support, read receipts, and better group management while maintaining SMS’s universal compatibility.

WhatsApp: Feature-Rich and Global

With over 2 billion users worldwide, WhatsApp offers rich media, international reach, and privacy controls that appeal to modern audiences.

Key benefits of mobile messaging:

  • Instant delivery and near-guaranteed visibility
  • Higher engagement and response rates
  • Support for multimedia content and interactive elements
  • Better demographic reach, especially younger users

6 Best Practices for Mobile Group Messaging

1. Build a Compliant Mobile Messaging List

Start by inviting your members, subscribers, or group participants to opt-in for SMS, RCS, or WhatsApp messages. Use existing channels like email invitations, social media, or event sign-ups. Always clearly state what messages they’ll receive and how often, ensuring compliance with TCPA and privacy regulations.

2. Use Dedicated Group Messaging Tools

Platforms like txtman make managing group messages efficient and scalable. Create lists similar to traditional email groups, but for mobile platforms. Segment your audience based on preferences, location, and engagement levels. Leverage automation for scheduled reminders, bulk messaging, and API integrations.

3. Personalize and Localize Your Messages

Personalized messages see 26% higher open rates. Segment your lists (active vs. dormant members), use first names, and localize content for specific regions or events. txtman’s tagging and list management features make personalization straightforward and effective.

4. Leverage Multimedia and Rich Content

RCS and WhatsApp support images, documents, links, and interactive buttons. Use these features strategically:

  • Event invitations with maps and RSVP buttons
  • Product updates with images and direct purchase links
  • Polls and surveys for immediate feedback

5. Schedule Smart Reminder Sequences

Timely reminders can increase event attendance by up to 40%. Create automated sequences:

  • Initial invite (1-2 weeks prior)
  • Pre-event reminder (2-3 days before)
  • Last-minute alert (day of event)
  • Post-event follow-up (thank you + resources)

6. Monitor, Analyze, and Optimize

Track delivery rates, response times, and engagement metrics. txtman provides detailed analytics to help you understand which channels and message formats work best. Use this data to refine your strategy—maybe your audience prefers WhatsApp for updates but SMS for urgent alerts.
