If you’ve looked at the analytics section in your account settings and noticed that your messages have a high bounce rate, you’re most likely engaging in what the cell phone carriers view as spam messaging behavior. Phone providers use dynamic spam filters to flag numbers that they determine to be sending spam messages. Your number can then be blocked by the carriers, which prevents your messages from delivering for an unspecified amount of time.
While the carriers aren’t forthcoming about what specifically will cause your messages to bounce, we’ve determined that sending out certain content in back to back Broadcasts or in a large number of individual messages can result in this occurring. We suggest avoiding use of the following:
- Recycled Content - Sending the exact same message in several back to back Broadcasts or consistently over a long period of time.
- Special Characters - The overuse of special characters such as $%@&!?.
- Excessive Capitalization - Sending messages with words in ALL CAPS.
- Phone Numbers - Including several consecutive numbers, such as a phone number. The number that you are texting from will appear on your contact’s phone when they receive your message. If your TextUs number is different than your office/desk line, calls will be forwarded to you.
- URLs or Email Addresses - URLs and email addresses can be sent in individual texts but they should not be included in Broadcast Messages or a large number of individual messages.
Here’s an example of what to NOT include in your message:
If you’ve been sending a high volume of messages that include any of the above, we recommend removing that content from your messaging. You’ll begin to see your deliverability rate increase and your bounce rate decrease! If you continue to experience high bounce rates after doing so, please contact us at email@example.com so we can investigate further.
