SMS Best Practices to Reduce Spam Blocks
Use clear consent, recognizable messages, accurate contact lists and delivery reviews to reduce avoidable messaging problems.
Good messaging begins with people expecting to hear from your business. These practices reduce avoidable problems; they do not guarantee delivery or replace the requirements in SMS Program Compliance Guide.
Before sending
- Keep consent records. Record who agreed, when, how and which messages they accepted. Do not use purchased or shared marketing lists.
- Use the approved purpose. A customer agreeing to appointment updates has not automatically agreed to unrelated promotions.
- Review your audience. Correct invalid numbers, avoid duplicate outreach and honor the Opted-Out list and other documented stop requests.
- Confirm the sender. Use your enabled business number and complete the required registration or verification before launching.
Write messages people recognize
- Identify your business and explain the reason for the message.
- Use accurate, relevant information and a clear next step. Avoid misleading urgency or promises.
- Link to a recognizable page you control or have verified. Avoid obscured destinations, misleading redirects and public link shorteners.
- Use templates for consistency, then check inserted contact details and the final text.
- Provide a clear way to stop messages. Do not pressure people to remain subscribed.
Control timing and follow-up
Send at reasonable times for recipients and within the frequency they were told to expect. Review the time zone before scheduling. Follow the volume and sending-rate limits approved for your program; splitting campaigns or rotating numbers is not a way to bypass a restriction.
Review the campaign report after sending. Investigate failures or unconfirmed results before another attempt. A successful request, an available balance or a recipient count is not a delivery receipt. See delivery troubleshooting.
Official and industry guidance
The FCC addresses consent and revocation for covered calls and texts under the TCPA. CTIA publishes voluntary messaging practices for the industry; CTIA is not a government regulator. See the FCC consent-revocation order and CTIA Messaging Principles and Best Practices. Our service also applies its own registration and acceptable-content requirements, explained in the compliance guide.
