â Best Practices for Writing Messages That Wonât Get Flagged
Carriers automatically block messages that look like spam or scams. These filters look for certain words, phrases, links, or patterns.
Hereâs how to keep your messages compliant:
1. Avoid "Spammy" Language
Donât use phrases like:
âFree money,â âCash prize,â âCongratulationsâyouâve won!â
âUrgent,â âAct fast,â âImmediate response requiredâ
âLose weight fast,â âMiracle cure,â âNo credit checkâ
â Instead, write natural, helpful messages that clearly state their purpose.
2. Use Full, Clear Website Links
Avoid:
Shortened URLs like bit.ly, goo.gl
Links that donât clearly match your brand
â Do:
Use full URLs
Make sure links are trustworthy and relevant
3. Keep Messages Short & Useful
Avoid long, paragraph-style texts
Focus on appointment reminders, helpful updates, or opt-in content
â Tip: If you have a lot to say, send a brief text and direct patients to check their email for full info.
4. Avoid Special Characters or Emojis
Dollar signs ($), emojis, or non-standard characters can trigger filters
â Stick to standard text with clear, plain language.
5. Make Sure Patients Opted In
Before messaging, confirm:
Patients clearly agreed to receive texts
You give them a way to opt out if needed
â This is required by TCPA & CTIA guidelinesâand keeps you trusted.
