Every brand has a daily sending limit to each mobile network. Here's what determines yours and how to grow it.

Every business registered to send text messages in the U.S. has a daily sending limit — the maximum number of messages they can deliver to each mobile network per day. Once you hit the limit, messages are rejected until it resets.

Where your limit starts

•Newly registered businesses begin at the entry-level limit

•This is usually enough for a few thousand messages per day across all major carriers

•It's a solid starting point for most small businesses

How to grow your limit

There's a verification process — sometimes called brand vetting — where an independent third party reviews your business (length of time operating, compliance history, industry, etc.) and assigns you a trust score. A higher score means a higher daily limit.

Standard vetting: Automated, usually fast (hours to a few days). Score can go up or down.

Enhanced vetting: Manual, deeper review. Takes 2–3 months. Can unlock the highest tiers.

How you'll know if you need to grow

You'll see rejection error 4780 in your dashboard when you hit the daily cap. If that's happening regularly, you've outgrown your starting tier.

What we do for you

  • Monitor your daily volume against your current limit

  • Alert you at 60%, 80%, and 95% of your cap

  • Help you initiate vetting when it makes sense

  • Submit the paperwork on your behalf

How to avoid hitting your cap

  • Spread marketing sends across multiple days instead of blasting everything at once

  • Consider whether different use cases should be on different brands (for companies with multiple subsidiaries)

  • Start the vetting process before you need it, not after

Important note about shared caps

All of your campaigns under a single brand share the same daily cap with each carrier. If you send 2FA, marketing, and appointment reminders, they all count against the same bucket. Plan accordingly.
