How to Build a Powerful SMS Subscriber List for your Business


Do you want to grow your subscriber list to scale up your business?

But which marketing platform can quickly boost your subscriber list? –  is an important question.

With a whopping 98% open rate, SMS is the best channel to optimize your subscribers.

SMS is a game-changer for eCommerce.

SMS marketing is the fastest-growing digital marketing channel. Unlike other channels, SMS is the most cost-effective and time-saving and can easily support and integrate with other marketing channels.

The average response time for any text is 90 seconds.

SMS marketing helps businesses of all sizes to send promotional messages to increase sales. But It’s important to understand that for SMS marketing campaigns consumer opt-in is required before sharing any messages.

Another interesting fact about SMS is that the opt-out rate of subscribers is under 5% which is far better when compared to the 15% of email subscribers that you lose every year if you only send out one email a week.

With SMS, you can easily convert your text messaging into an entire SMS marketing strategy from signup to conversion and long-lasting customer relationships.

Top brands like Reebok, CNN, Tommy Hilfiger, Chili’s, Kohl’s, and many other known brands all use SMS marketing to reach their customers.

Another popular brand is Redbox that uses SMS marketing to engage its customers, personalize its service, and promote DVD rentals. Its “The 10 Days of deals” SMS campaign generated nearly 1.5 million text messages, resulting in more than 200,000 new Redbox Text Club Members.

How to set your SMS subscriber list up for success?

For this, you will need to take into account how to manage all your customer contacts and messages.

Let’s walk through each step to understand clearly:

1. Relevant messages should be shared 

It is essential to maintain a good brand reputation for those who want to join your subscriber list. You can build a good image of a brand by practicing compliance and implement this market principle that If the user asks for one thing they don’t share the other irrelevant things.

For Instance, if your customer agreed to take your survey, don’t start sending them your newsletter or if your customer asked for product promotions, don’t send them updates on your ongoing events.

Also, users have to give you permission to send promotional messages to them. You can’t send a message without their direct consent even if you have got their number from any online data otherwise it will downturn brand reputation.


2. Selection between shortcode and long code

Both the codes have different ways to build your SMS subscriber list.

Shortcode is a 5 to the 6-digit phone number that is completely automated and is good for reaching an unlimited number of people but you cannot have a two-way conversation with the customers who text in.

Long code is a standard 10-digit phone number that is best for a two-way conversation with users to several thousand contacts such as any company phone number is a long code, and using that can make texting easier for everyone.

Unlike Long code, shortcodes are expensive and tricky. 

Long codes can feel more personal, but they also can only send one text per second.

So choosing appropriate code is vital.

3. Utilize SMS features to streamline your messaging
