Call to action
Opt-out instructions

ACME: Flash sale! 30% off all items today only.
Shop now: acme.co/sale
Reply STOP to opt out

URL Shortening

Use branded short links when possible
Track clicks for attribution
Avoid suspicious-looking URLs
Test links before sending

Timing

Guideline	Reason
Send during business hours	Respect quiet times
Avoid early morning/late night	Prevent annoyance
Consider time zones	Send at local optimal time
Don’t send on holidays	Lower engagement

Optimal send times:

Tuesday-Thursday typically perform best
10am-12pm and 2pm-4pm local time
Avoid Monday mornings and Friday afternoons

Compliance Requirements

SMS has strict regulatory requirements. Non-compliance can result in significant fines.

TCPA (US)

The Telephone Consumer Protection Act requires:

Express written consent before sending marketing SMS
Clear disclosure of message frequency
Easy opt-out mechanism
Immediate honor of STOP requests
No messages to numbers on DNC lists

Collect Consent

Get explicit opt-in with clear disclosure

Document Consent

Record timestamp, method, and language shown

Confirm Opt-In

Maintain Records

Keep consent records for compliance audits

Required Disclosures

When collecting SMS consent, disclose:

Message frequency (e.g., “up to 4 msgs/month”)
Message and data rates may apply
How to opt out (reply STOP)
Link to privacy policy

Example opt-in language:

By entering your phone number, you agree to receive
marketing text messages from ACME (up to 4 per month).
Message and data rates may apply. Reply STOP to cancel.

Opt-Out Handling

RevBridge AI automatically:

Recognizes STOP, UNSUBSCRIBE, CANCEL, QUIT
Immediately suppresses the number
Sends confirmation of opt-out
Prevents future messages

Never message someone who has opted out. This violates TCPA and can result in

500-

1,500 per message in fines.
