Incentivize your customers by offering rewards and special offers on joining your SMS club. Ensure your SMS subscribers get the red carpet value by providing instant responses and exclusive deals for building lifelong rapport with your customers.

You can also entice your customers with non-promotional offers in return for subscribing to your SMS club. The non-promotional offers may include free shipping, exclusive or early access to sales, product launches or recommendations, tips & tricks, and more.

#2. Opt-In Using Keyword

In the SMS Marketing language, a keyword is a word or phrase that your customers will text to either your phone number or SMS short-code to join your SMS club. Choose a keyword that is both creative and memorable. The keyword should align with your brand’s overall marketing strategy, and the potential sms subscribers should be able to relate to your brand or product. The method is simple and saves your customers from the hassle of filling up online or paper forms with loads of information. Invite your customers to text you the magic keyword and even offer them a deal or a promotion for texting.

A pizza chain executed a keyword campaign to grow their SMS subscriber list under which they offered free pizza to the first 100,000 people who texted “FREEPIZZA” to their short-code. Campaigns like this can become an outright hit and also help you gain thousands of new SMS subscribers.

#3. Promotion across Social Media

Add a simple check box during website checkout during an online purchase to keep the signing up procedure quick and easy for your customers. The less work your customers have to do, the more likely they are to sign up.

#8. Crisp and Clear Messaging

People refrain from giving out their contact information and permission to contact when they are not aware of what they are signing up for. While approaching your customers for signing up for SMS subscription, clearly outline the frequency with which you will be contacting them, why you are texting them in the first place, and any necessary disclosures like associated data charges or privacy policy.

Do not forget to reassure your prospective subscribers that you will not sell their information to a third party and only use your contact information to send them exclusive discounts, offers, and updates. By keeping things transparent, you will build trust in your customers, grow your retention rate, and more customers will willingly refer you to their friends.

#9. In-Store Marketing

From offices to brick-and-mortar stores, leverage all your sites to promote your SMS opt-ins using old-school promotions like signs, posters, and business cards. You can pair incentives with this tactic as well. While people are in your store, offer them a discount or a free service on their next visit for opting-in during checkout.

People love giving feedback as it makes them feel heard and needed. You can have your customers fill a paper or online form asking for feedback along with explicit permission to opt-in. Do not forget to let your customers know how subscribing will add value and put them front and center.

#10. Use Influencers

Use Influencers

You can reach targeted audiences by collaborating with influencers in your niche. Like many businesses, you can give a custom code to influencers to put out on their social media accounts. The customers text the same keyword and may avail of a discount or a premium deal using the custom code. The custom codes can further track revenue generated from them.

#11. Leverage Email Marketing

Leverage Email Marketing

Email is another cost-effective marketing channel. Convert your email list to SMS subscribers by sending an email marketing campaign highlighting the perks of joining your SMS club. You can also add SMS opt-in as a call-to-action in the email signatures of all employees.

Retain the Existing Subscribers – Best Practices

While the above strategies will help you grow your SMS subscriber list for effective SMS campaigns, you should factor in your existing subscribers, as they are your warmest leads. We should not ignore that it is equally important to retain the existing subscriber list.

Compliance is the key

Based on the Telephone Consumer Protection Act (TCPA) guidelines for SMS marketing, you must have prior consent to send a promotional message. In addition to that, you can only contact via text between 8 a.m. to 9 p.m. in the recipient’s time zone.

You must also include necessary disclaimers in your promotional messages. These disclaimers must inform customers about the expected frequency of messages, applicable data and message rates, privacy policy, option to ask for help, steps to unsubscribe, and terms and conditions.

It is noteworthy that your business will receive fewer complaints on sending appropriate marketing messages to customers and being compliant. It will also lead to higher customer satisfaction. Disregarding these regulations can lead to a loss of trust with customers.

Be Consistent

While sending too many messages may irritate your customers, your customers may forget about you and the purpose of your messages if you send too few messages. In both scenarios, the customers may end up opting out of your SMS club. It is best to keep the frequency and intervals of your messages consistent for best results.

Always Personalize

It should be of interest that customers have a 306 percent higher customer lifetime value if they feel they have a personalized relationship with a brand. Address your subscribers by their names and wish them on their birthdays and festivals to add value to the relationship.

In the case of two-way SMS, ensure that your response is prompt or reply with an automated message.
