If your texts stopped getting delivered, or your calls are showing up as "Spam Likely," your number may have been blocked or flagged. This is one of the harder problems to fix, because most of the decision happens at the phone carriers and the analytics companies that score numbers, not inside Raise More. We can help you investigate and request remediation, but we cannot instantly unblock a number, and some situations require waiting or moving to a new number.
This article walks through how to tell what kind of block you have, why it happened, and what you can actually do about it.
First, figure out which kind of block it is
There are two separate things people call "blocked," and they have different causes and different fixes.
Texts not being delivered (SMS filtering). Your messages send but never arrive, or they arrive for some recipients and not others. This is carrier filtering. A carrier has decided your traffic looks like spam and is dropping it. In delivery reports you will see messages marked as filtered or undelivered rather than delivered. Filtering can be temporary or sustained, depending on what triggered it.
Calls labeled as spam (voice reputation). Your calls still connect, but the recipient's phone screen shows "Spam Likely," "Scam Likely," or a similar warning, and people stop picking up. This is a caller reputation problem. The carrier is delivering the call but warning the recipient.
A number can have one problem, the other, or both at once. Knowing which one you are dealing with decides what you do next.
Why numbers get blocked
For texting, the most common causes are incomplete or incorrect 10DLC registration (the carrier-required registration for business texting), sending high volumes of identical or near-identical messages quickly, content that trips spam filters (links, certain keywords, all caps), and texting people who never opted in. Carriers watch for these patterns and filter the number that produces them.
For calls, the cause is reputation built up over time. High call volume, a lot of very short calls, and complaints or "block this caller" actions from recipients all push a number toward a spam label. Caller-ID attestation (STIR/SHAKEN) also matters: if your number is not properly attested, carriers are more likely to flag it.
Steps to recover
Recovery is mostly about stopping the behavior that caused the block and then asking the carriers to reconsider. There is no button that fixes it instantly.
Confirm what is happening. Check whether it is filtered texts or spam-labeled calls. If you are not sure, contact Raise More support and we can look at the delivery and call data on the provider side.
Stop the behavior that caused it. This is the most important step, and skipping it means any other fix will not hold. For texting: pause large templated blasts, make sure your 10DLC registration is complete and accurate, vary your message content, and confirm everyone you are texting actually opted in. For calls: reduce volume, avoid rapid-fire short calls, and make sure your caller ID is verified.
For calls, register with the Free Caller Registry. This is a free service that lets you report your number as a legitimate caller to the analytics companies that feed spam labels to the carriers. It improves how your number is scored over time. It is not instant, but it is the standard remediation path for voice reputation.
Contact Raise More support. We can investigate what the provider is reporting and, where a remediation request is possible, submit one on the provider side. We will tell you honestly what we can and cannot do for your specific case.
Some of these steps take time. Carrier and analytics-provider scoring updates on their own schedule, often days, sometimes longer. If a number is badly damaged and remediation does not work, the practical option is to retire it and start fresh with a new number, which we can help you set up.
Preventing it from happening again
The same things that cause blocks are the things that prevent them. Keep your 10DLC registration complete and current. Only text people who opted in. Avoid sending large batches of identical messages. Keep message content clean and personal where you can. For calls, keep your caller ID verified and avoid patterns that look automated, like long runs of very short calls. A number that sends compliant, opted-in traffic at a reasonable pace rarely gets blocked in the first place.
When to contact support
Reach out to Raise More support if:
You are not sure whether your problem is text filtering or a voice spam label.
Your texts are being filtered and you have already fixed your registration and sending habits.
Your calls are labeled as spam and registering with the Free Caller Registry has not helped after some time.
You want to retire a damaged number and set up a new one.
When you contact us, tell us the affected number, whether it is texts or calls, and roughly when the problem started. That helps us look in the right place.
FAQ
Can Raise More just unblock my number? No. The block is decided by the carriers and analytics providers, not by us. We can investigate and request remediation on the provider side, but we cannot force a number to be unblocked.
How long does recovery take? It varies. Once you stop the behavior that caused it, carrier and analytics scoring can take days or longer to update. There is no guaranteed timeline.
Will I have to get a new number? Sometimes. If a number is badly damaged and remediation does not work, the most reliable fix is to retire it and use a new one. We can help with that.
Does fixing my 10DLC registration unblock my texts right away? Not necessarily on its own, but it is required, and filtering usually will not clear until your registration is correct and your sending habits have changed.
My calls connect but say "Spam Likely." Is that the same as being blocked? No. That is a voice reputation label, not a filter. The call still goes through, but the warning discourages people from answering. The fix is the Free Caller Registry and changing your calling patterns, not the texting steps above.
