What's the Best Messaging Frequency for RCS?

RCS Messaging Frequency: Finding the Sweet Spot

How often should you message customers via RCS? Here's what the data shows.

The Frequency Sweet Spot

Marketing Messages:

• Optimal: 2-4 messages per month per recipient
• Minimum: 1 message per month (to maintain brand recall)
• Maximum: 6 messages per month (before opt-out rates spike)
• Industry average: 3 messages per month

Transactional Messages:

• No strict frequency limit (customer-initiated context)
• Examples: order confirmations, shipping updates, appointment reminders
• Higher frequency is acceptable because customer expects them

Service Messages:

• 1-2 messages per interaction (avoid back-and-forth clutter)
• Examples: support ticket updates, resolution notifications

What Happens with Too Few Messages

Under 1 message per month:

• Customers forget who you are
• Lower brand recall
• Reduced engagement when you do send
• Higher cost per conversion (need to re-acquire attention)

The data:

• 1 message/month: 30-40% open rate
• 1 message/quarter: 15-25% open rate
• 1 message/year: 5-10% open rate

Infrequent messaging hurts engagement because customers forget your brand exists.

What Happens with Too Many Messages

Over 6 messages per month:

• Notification fatigue sets in
• Opt-out rates increase dramatically
• Engagement per message decreases
• Customer complaints rise

The data:

• 2 messages/month: 3-5% opt-out rate
• 4 messages/month: 5-8% opt-out rate
• 8 messages/month: 15-25% opt-out rate
• 12+ messages/month: 30-50% opt-out rate

More isn't better. There's a clear threshold where frequency becomes annoying.

Industry-Specific Recommendations

• 3-5 messages/month optimal
• Cart abandonment: immediate + 24h follow-up

Engagement-Based Frequency

Don't use the same frequency for everyone. Adjust based on engagement:

High Engagement (Opens 70%+ of messages):

• Can send 4-6 messages per month
• These customers want to hear from you
• Test higher frequency carefully

Medium Engagement (Opens 30-60% of messages):

• Standard frequency: 2-4 messages per month
• Monitor for signs of fatigue
• A/B test timing and content

Low Engagement (Opens under 30%):

• Reduce to 1-2 messages per month
• Focus on re-engagement campaigns
• Consider sunsetting if no improvement

Time-of-Day Best Practices

Best times to send:

• 10 AM - 12 PM (mid-morning)
• 2 PM - 4 PM (mid-afternoon)
• 6 PM - 8 PM (evening commute)

Avoid:

• Before 9 AM (too early)
• 12 PM - 1 PM (lunch hour, busy)
• After 9 PM (too late, intrusive)
• 10 PM - 8 AM (regulatory requirement in many regions)

Day of week:

• Tuesday, Wednesday, Thursday perform best
• Monday is busy (people catching up)
• Friday afternoon is low engagement
• Weekends vary by industry

Frequency Management Tactics

Preference centers: Let customers choose how often they want to hear from you:

• Daily deals
• Weekly digest
• Monthly newsletter
• Major announcements only

Smart cadence: Space messages evenly throughout the month rather than batching:

• 4 messages/month = 1 per week
• Better than 4 messages in one week, then nothing for 3 weeks

Throttling: Reduce frequency for customers who:

• Haven't engaged in 60+ days
• Have shown opt-out signals (clicking unsubscribe button)
• Have lower lifetime value
• Are in specific segments (e.g., one-time buyers)

Sunset policies: Automatically reduce or stop messaging customers who:

• Haven't engaged in 90+ days
• Have opted out and then re-engaged (be cautious)
• Have unsubscribed from email (possible signal)

Measuring Frequency Success

Track these metrics:

Per-customer metrics:

• Messages sent per recipient (avg)
• Opt-out rate by frequency
• Engagement rate by frequency
• Revenue per message by frequency

Campaign metrics:

• Opt-out rate per campaign
• Complaint rate per campaign
• Engagement quality score
• Conversion rate

Red flags:

• Opt-out rate >5% in any campaign
• Complaint rate >0.1%
• Sudden drop in engagement
• Increase in "unsubscribe" button clicks

A/B Testing Frequency

Test different frequencies with small segments:

Test 1: 2 vs 4 messages per month

• Send 2 messages to segment A, 4 to segment B
• Measure engagement, opt-out, revenue
• Run for 60-90 days

Test 2: Weekly vs bi-weekly

• Segment A: weekly messages
• Segment B: bi-weekly messages
• Compare performance

Test 3: Burst vs spread

• Segment A: 4 messages in first week of month
• Segment B: 1 message per week
• Compare engagement and opt-out

Use results to optimize frequency for your specific audience.

The Bottom Line

Start with 2-4 marketing messages per month and adjust based on engagement. Monitor opt-out rates closely and reduce frequency if they exceed 5%. Use preference centers to let customers self-select frequency. And remember: quality and relevance matter more than quantity.

The best frequency is the one that delivers value without becoming annoying. Test, measure, and optimize continuously.
