SMS Campaign Sending Limits and A2P Registration

How A2P rules and smrtPhone limits affect your SMS campaigns

If your SMS marketing campaign in Invelo didn’t send successfully, the most likely reason is that the phone number on your smrtPhone account isn’t registered for A2P 10DLC (Application-to-Person 10-Digit Long Code).

Because all texting runs through smrtPhone, your sending limits are determined by the registration status and plan you have with smrtPhone—not Invelo.


Texting Limits in smrtPhone

Here’s how smrtPhone defines the daily limits:

  • Without A2P registration: Up to 200 texts per phone number, per day
  • With A2P registration:
    • Low Volume plan: Up to 6,000 texts/day across all registered numbers (note: T-Mobile caps this at 2,000)
    • Standard plan: Up to 200,000 texts/day, depending on your Trust Score

To confirm whether your A2P campaign is active, check the Trust Center inside smrtPhone. If you’re unsure about your plan or limits, contact smrtPhone Support directly for clarification.


Next Steps to Get Your Campaign Running

  1. Complete your A2P 10DLC registration in smrtPhone.
  2. Once registration is confirmed, we can help you clone and relaunch your SMS campaign so it sends successfully.
  3. As a best practice, add the filter “Primary phone number is known” to ensure your campaign only sends SMS to records with a valid phone number.


Understanding Compliance: Why A2P Registration Matters

It’s natural to feel that the A2P process is complex, especially when it comes to consent requirements. To clarify:

  • These rules don’t come from Invelo or smrtPhone specifically.
  • They are part of federal TCPA (Telephone Consumer Protection Act) regulations, which apply to all texting platforms.

What This Means for You

  • Only text leads who have explicitly opted in.
  • For prospects who haven’t consented, use email or direct mail instead.
  • Update your intake process to gather consent (e.g., through a web form with an opt-in checkbox).

🚨 Ignoring these rules can lead to hefty fines—applied per text message. While some investors choose to take the risk, the potential costs are significant.


Key Takeaway

Invelo and smrtPhone work seamlessly together for campaigns and communication. However, compliance with A2P 10DLC and TCPA regulations is mandatory across all platforms.

By registering your phone number for A2P, verifying consent from your leads, and applying best practices in your campaigns, you’ll be set up for safe, scalable SMS marketing that protects your business in the long run.
