When people read 90 percent of all texts within three minutes, SMS Marketing is one of the best ways to connect with your audience. And not only is there a high likelihood that your message will be seen, but SMS messages also receive click rates of 36 percent.

Choosing an SMS platform can become complicated. Many platforms boast dozens of features and not all are created equal. 

It’s important to choose a platform that helps you meet your business goals by having the ability to track return on investment (ROI), personalize messages, and segment your audiences.

Plus, by using a unified marketing platform that puts email and SMS under the same roof, you can more effectively build out your automations and more accurately measure the performance of your campaigns.

What is an SMS marketing platform?

An SMS marketing platform (sometimes referred to as an SMS marketing service) is a tool used to create and send text messages to a specified list of phone numbers.

You can use text messages to send anything from flash sale notifications to shipping confirmation emails, back in stock notification texts, abandoned cart texts, and much more.

Most also allow you to send campaigns as well as automated text messages that trigger based on a shopper’s actions, such as signing up for text alerts or requesting more information about a product.
