You send a text. The client never gets it. You don't get a bounce notice. Here are the 7 most common reasons insurance agency SMS messages disappear into the void, and exactly how to fix each one.
Most common cause in 2026. US carriers filter all unregistered A2P traffic. Brand and campaign registration required. Fix: register both.
You hit the per second message cap for your campaign tier. Overflow messages get dropped. Fix: upgrade campaign tier or throttle sends.
Words like "loan", "free trial", "claim", certain URLs, or shortened links trigger carrier filters. Fix: plain language, full domain URLs.
| Failure Mode | Symptom | Fix |
|---|---|---|
| Unregistered 10DLC | 100 percent of messages silently filtered | Complete brand and campaign registration |
| Throughput cap hit | First N messages deliver, rest vanish | Upgrade campaign tier or queue throttle |
| Content filter hit | Some messages deliver, others do not | Rewrite templates, remove trigger words and short URLs |
| Opt out ignored | Sending to a STOPped number returns error | Respect STOP. Never text that number again. |
| Carrier block on number | All messages from your sender fail | Contact your CRM provider, request number swap |
| Quiet hours hit | Messages sent at 7am fail to deliver | Enforce 9am to 8pm local send window |
| Landline or VoIP target | Delivery impossible | Phone number validation on form intake |
Use a phone on a different carrier than your own. If you get it, carrier filter. If not, provider problem.
Your CRM has send logs. Look for status codes. "Delivered" vs "Failed" vs "Undelivered".
Log into your provider dashboard. Brand status should be "Verified." Campaign status should be "Approved."
Send the same message content via a different channel. Swap URLs, remove trigger words, retry.
10DLC registration, content review, throughput tuning, and number health monitoring. Stop guessing why your texts are not landing.
