What is an SMS campaign?

An SMS campaign is a marketing strategy that sends targeted text messages to promote products and services or convey information. It’s cost-effective and allows businesses to reach a broad audience instantly and track the campaign’s success through response rates and conversions.

SMS campaigns have limitations on visuals, with a character count of up to 160. Yet this marketing channel is fast and has proven to be effective.

By segmenting your SMS marketing audience, you can send different messages to different people. Automated text messages that confirm transactions, provide shipping information, and remind about abandoned carts can all be automated. This way, they are sent only to customers who trigger them.

Types of SMS campaigns

A successful SMS marketing strategy begins with choosing the right campaign type. Whether you’re announcing a sale or gathering customer feedback, there’s a messaging campaign for every goal. 

Here are common types of SMS marketing campaigns:

  • Promotional SMS campaigns: These campaigns are designed to drive sales. You can share exclusive deals, discounts, and offers. A promotional SMS, delivered at the right time, can significantly boost engagement and drive conversions.
  • Transactional SMS campaigns: Transactional messaging campaigns provide critical updates like order confirmations, shipping notifications, or payment receipts. These messages enhance customer trust by keeping them informed every step of the way.
  • Reminder campaigns: Reminders are perfect for addressing cart abandonment, renewing subscriptions, or alerting customers about expiring offers. A quick SMS reminder puts your business back on their radar while showing them you value their time.
  • Customer feedback requests: Feedback campaigns invite customers to share their opinions after a purchase or service interaction. They help businesses gather valuable insights and improve customer satisfaction.
  • Welcome SMS campaigns: Welcome messages greet new subscribers or customers. These campaigns create a strong first impression and set the tone for future communication while introducing your brand or services.

  • Personalization
  • Recipient list
  • Scheduling information
  • A CTA (call to action)

Expert tip: Combine SMS campaigns with other marketing channels

You could use SMS campaigns solely to deliver critical and time-sensitive messages at every step of the customer journey.

However, best practice shows that short text messages are incredibly effective when combined with other communication channels, like email and Facebook retargeting.

For example, SMS campaigns to non-openers. Firstly, you launch your email campaign, and the next day your text campaign sends an SMS to subscribers who didn’t open your email — which you can do step-by-step with Omnisend.

SMS is a great tool for sending time-sensitive messages, as they’re usually opened quicker than an email if sent at the right time.

Simultaneously, you may also launch Facebook retargeting to the same audience. This way, you’ll get more touchpoints with your customers, and it will be easier to convince them to shop with you — particularly with holiday campaigns.

“We may have a ‘free shipping today only’ email that goes out. Some customers won’t get that email until the following day when the sale ends. We can use SMS as an alternative to reach those customers.”

Best practices for creating effective SMS campaigns

Creating an SMS campaign involves more than just sending messages. Applying best practices transforms a good strategy into a great one. Follow these proven practices to launch successful SMS campaigns:

SMS opt-in and consent

Before launching your first SMS campaign, ensure you receive the customer’s consent. Like email permissions, the law requires that your contacts opt in for promotional content via SMS.

You can collect opt-ins in a few different ways:

  • By adding an extra field for phone numbers in your signup forms
  • By asking for a customer’s phone number at the checkout
  • Using “Text to Join,” where people text a keyword to your number

In compliance with the TCPA (Telephone Consumer Protection Act), consent must be clear, voluntary, and not conditional on a purchase. Also, include an easy way for recipients to unsubscribe from your messages.

Personalize your messages

A well-crafted, personalized SMS communicates to customers that you value and appreciate their needs and preferences. Adding a personal touch, like addressing them by name, referencing past purchases, or highlighting their preferences, makes the reader feel more connected to your brand. 

This approach builds trust and boosts engagement. People are far more likely to respond to messages that feel relevant to them.

For example, instead of sending a generic message like “Stock is updated. Shop now: (Link),” consider a personalized alternative like “Hi (Customer Name), your favorite sneakers are back in stock! Enjoy a 10% discount: (Link).”

See the difference?

The personalized message makes the customer feel recognized and appreciated, while the generic one comes off as impersonal.

Personalized messages do more than deliver information — they build relationships. These meaningful connections are what turn one-time customers into loyal ones.

Use clear and compelling CTAs

A great SMS grabs attention, but a strong CTA drives results.

Ensure your CTA is direct, easy to understand, and aligns with your goal. Communicate the actions you want customers to take, such as clicking a link, claiming a discount, or confirming an appointment. 

For example, a phrase like “Shop the sale before it ends: (Link)” creates urgency and clarifies what actions to take. Compare this to vague instructions like “Check out our website,” which lack context or motivation.

For even better results, pair your CTA with a benefit or incentive. Highlight the value of taking action with messages such as “Use code SAVE20 at checkout to get 20% off your order today: (Link)” or “Buy 1, Get 1 Free — Offer ends tonight: (Link).”

By emphasizing the benefits, you make it harder for your audience to resist. Clear, compelling CTAs encourage them to act quickly.

For example, Oh Beauty’s SMS combines all of these best practices to encourage customers to act immediately:

Time your messages thoughtfully

Timing can make or break the success of your SMS campaigns. Even the most engaging message can fall flat if it isn’t well-timed.

To maximize engagement, schedule your texts for mid-morning or early evening, when people are most likely to be receptive. These are moments when most individuals have settled into their routine and are more likely to check their phones.

Avoid sending messages too early, too late, or during holidays unless they’re critical. Nobody likes their dinner interrupted or their peace disturbed by non-urgent texts.

If you’re unsure when your audience is most active, test different times and review the engagement data. Top SMS campaign management tools can help schedule messages at the best times for each segment of your audience.

Keep it short and focused

When it comes to SMS, less is more. With a character limit and a busy audience, it’s important to keep your messages brief and to the point. 

The goal is to capture attention quickly, so focus on one main idea per message. Trying to cram too much information into one text can confuse your audience or cause them to lose interest.

For instance, instead of saying, “We have an amazing sale on our entire store right now! Get 20% off everything, and don’t forget about our new arrivals section with tons of great deals, too.” Opt for a concise alternative like, “20% off everything — today only! Shop now: (Link).”

Short, focused messages fit within SMS limitations, increasing the chances that your audience will read and engage.

This SMS from CASETiFY is a prime example of a short, engaging message paired with a clear CTA:

Is an SMS campaign template needed?

As SMS campaigns can be only text, the only template you might use is how you write.

Here are five curated text messages that you can take inspiration from:

  • Hi! It’s (Brand Name). Your 10% off code is: (Code) Shop now: (Link) Text us at (Phone number) if you have any questions!
  • (Brand Name): Our best offer just got even better. Buy a Hardcore Bundle and save an additional 20% on top of the usual 25%. Seriously. Click the link below to access now (Link)
  • TWO HOURS LEFT to get 40% off your entire order at (Brand Name)! Use code: (Code) at checkout. Sale ends TONIGHT Dec. 1, 11:59pm EST! (Link)
  • (Brand Name) DEALS! Today, all swim is BUY ONE GET ONE FREE! Code: (Code) expires tonight at midnight. (Brand name) will be offering a new deal every Friday in December, so stay tuned! Shop at: (Link) Unsubscribe: (Link)
  • (Brand Name): Here are some great gifts for you to give or to keep! All on sale are ready to ship. (Link) Unsubscribe (Link)
