Is there a limit to how many SMS messages I can send at 1 time?

Technically there is really no limit, however these are long code numbers and mobile carriers are a little more cautious letting someone send thousands of SMS messages at 1 time for SPAM reasons.

With our platform, we have many safety measures built in to help avoid any potential issues.

1. You have the capability to assign multiple numbers to an account and then rotate through those numbers simply by ticking a checkbox! This provides a good safety measure in that to mitigate potential problems, it’s best to distribute the load of your SMS traffic, so that SMS messages with identical or similar contents are sent from as many different outgoing phone numbers as possible.

2. You have the capability to spin the text of your messages so that your message content varies with each outgoing message.

3. You can throttle the sending rate of your messages so that your messages get sent at a slower rate. Per carrier restriction, the fastest(default setting) you can send SMS on 1 long code is 1 SMS/second. However, you can slow that down to exercise extra caution. The slowest setting will send at rate of 10 SMS per minute or 1 SMS every 6 seconds.
