Spam Remediation Best Practices

If carriers decide your messages look like spam, they can filter them, flag your phone numbers, and in serious cases your SMS provider can suspend your account. Using good templates and enough phone numbers is the best way to prevent this, and acting fast when you see spam alerts keeps the problem from growing.

Why do I need at least 5 phone numbers?

Lead Sherpa rotates through your numbers as it sends, so no single number sends too many messages in a short time. That's why every market needs at least 5 numbers. We recommend 10.

How many templates should I have?

Keep 15 to 20 templates in every category you use, and never fewer than 10. Refresh them at least once a month, and avoid the words in Blocked Words/Phrases.

How do I know if my numbers are being flagged?

Many failed messages in a row usually mean your numbers have been flagged as spam. Lead Sherpa also shows a notification when this happens. Review your templates and wait a while before sending again.

Getting a lot of failures or alerts? Stop sending

If you're not sure what's happening, stop sending messages right away. Check the error codes in your Twilio or Telnyx message logs (Twilio: Monitor tab; Telnyx: Reporting or Debugging in the left menu). For questions about errors, filtering, or your account status, contact Twilio or Telnyx support directly.
