When sending group messages (Broadcasts) from your Salesmsg number, carriers may block your texts if they look like spam. To avoid this, make sure to:

  • Get permission from people before texting them

  • Say who you are and what company you're with in your first message

  • Always include a clear way to unsubscribe (like “Reply STOP to opt-out”)

Following these simple steps helps your messages get delivered and keeps you compliant.


Texting Tips to Keep Your Messages Flowing Smoothly

Stay In the Know
We highly recommend checking out the Messaging Principles and Basic Practices guide - it lays out the foundation for safe, compliant messaging.


What You Can Do Right Now

To stay compliant and keep your messages delivering smoothly, here are a few quick tips:

  • Always get permission before texting someone, *especially for marketing or non-essential messages.

  • Text during normal hours. Avoid late-night or early-morning messages unless it’s truly urgent.

  • Respect do-not-call and do-not-disturb lists. These exist for a reason - don't text those numbers.

  • Know your purpose. Be ready to explain what you’re using SMS for by choosing a category from this list: SMS Use Cases


Keep It Short & Sweet

  • A standard SMS = 160 characters or less.

  • Go over that? It still sends, but it’ll cost extra credits, so shorter is cheaper.

  • Use Salesmsg’s built-in link shortener to save space and avoid problems.

    • 🚫 Avoid 3rd party tools like Bit.ly, TinyURL, etc. - they’re often flagged as spam and could block your message.

    • ✅ Using the built-in shortener = fewer characters + better deliverability. Win-win!


Boosting Broadcast Performance

Want to personalize your mass messages with names, companies, or other custom info? You can, using:

  • Internal merge fields

  • Integration fields

  • HubSpot lists

But heads up - the more personalization you add, the slower your send time.

If speed or deliverability is your top priority, try:

  • Sending simpler messages without merge fields

  • Using one personalization feature at a time


Frequently Asked Questions

My messages are getting filtered. What can I do?

Be ready to clearly explain what you're using SMS for (your "use case"). This helps carriers understand that your messages are legit.

How do I know if my message was blocked or filtered?

Check the "Failed Reason" column in your Broadcast Analytics page. It’ll show exactly why a message didn’t go through.
