Why do U.S. customers have to register their brand and messages?

The major U.S. carriers (e.g., AT&T, T-Mobile/Sprint, etc.) are requiring that brands and campaigns (message samples) be registered in an effort to reduce spam and possibly increase throughput.

The Campaign Registry is the independent agency these major carriers have contract as their reputation authority of business messaging on 10dlc.

What is the best way to reliably send urgent alerts to my network?

Ensuring that each and every one of your time-critical bulk messages reach their intended recipients is essential. However, the increasingly strict anti-SPAM policies of carriers are blocking good messages along with the bad. Below, we offer our two best tips to ensure all your important bulk SMS messages are successfully delivered.

1. Personalize SMS – By personalizing your outgoing bulk messages with recipients’ names or other unique content, you minimize the appearance of duplicate content, thereby reducing the risk of any messages being blocked by the receiving carrier for violating their policies. You can accomplish this using the mail merge feature of our Bulk SMS product.

2. Avoid Sending URLs, Email Addresses, or Phone Numbers – When possible, avoid using including any of these in your bulk SMS blasts. Carriers view them as suspicious and are more likely to block message deliveries.
