I'm sorry for the delayed response to this! At this time, we do not have an SMS marketing option but we do have some great blogs on how to integrate it into your email marketing! We also have our Text to Join feature which allows your customers to sign-up to your lists through text. If you have any additional questions, please don't hesitate to reach back out.
Email is producing slowly diminishing returns because people hate it due to all the spam. We really do need to start slowly replacing email with SMS. The millennial generation and anyone younger, which is a huge part of our market (and that of many retailers!) uses phones and text, not email. Without an SMS option, the effectiveness of email alone is going to continue to diminish.
Can you tell us if there is an SMS option on the horizon? Is is something Constant Contact is working on? If not, we can find another company. But I've been with you for so long and trust you so completely that I would prefer to use CC if this will be coming in the future.
We completely understand why SMS marketing would be an important tool to use, and we are currently working on possibly implementing that into our product. We do have many integrations as well that do SMS marketing that you can find in your account as well under the integrations tab. We do appreciate your feedback, and I am more than happy to submit it over to our engineers for review. Thank you!
