8 tips for effective SMS marketing campaigns

Text messaging is one of the most effective ways to reach customers. More businesses than ever are using SMS text message marketing campaigns as part of their digital marketing efforts, and for good reason: no other channel delivers messages with the same speed, visibility, and response.

Common SMS marketing use cases include:

• Appointment and event reminders
• Time-sensitive offers and deals
• Promotional campaigns
• Order confirmations and shipping updates
• Loyalty program alerts
• Two-way customer service conversations

Why text messages?

A well-targeted email campaign achieves an average open rate of around 21 percent. SMS open rates consistently reach 90 to 98 percent, with 80 percent of messages read within five minutes of delivery. That kind of immediacy does not exist in any other marketing channel.

The numbers across the board back this up:

• SMS has a 98 percent open rate, compared to around 20 percent for email
• The average response rate for SMS campaigns is 45 percent, versus roughly 6 percent for email
• Conversion rates for well-optimized SMS programs range from 21 to 30 percent
• SMS marketing ROI ranges from $21 to $71 for every $1 spent, with abandoned cart and flash sale campaigns often hitting the upper end
• 82 percent of businesses agree SMS marketing is an effective way to drive revenue

Text messages are direct, short, and immediate. Unlike emails that can sit unread for hours, a text is hard to ignore. Here are eight tips for running effective SMS marketing campaigns that get results.

1. Get permission and allow easy opt-out

To send a marketing text message, you must have explicit prior written consent from the recipient. This is not just best practice; it is a legal requirement under the Telephone Consumer Protection Act (TCPA) and the rules enforced by US mobile carriers.

You can collect consent when a customer signs up for your service, joins a loyalty program, attends an event, or opts in through a web form. Make the value clear upfront: tell subscribers exactly what they will receive and how often. For example, Subway built one of the most recognizable SMS programs by offering subscribers exclusive weekly coupons in exchange for their opt-in.

Equally important: make opting out easy. The standard opt-out keyword is STOP, and you must honor it immediately. As of 2025, the FCC requires one-to-one consent, meaning a single opt-in cannot be shared across multiple brands or affiliates. Each business program requires its own explicit consent.

Not sure how to approach SMS opt-in best practices? Double opt-in, while not required, adds an extra layer of protection and helps ensure your list contains genuinely engaged subscribers.

2. Segment your audience

The most effective SMS campaigns use audience segmentation to send targeted messages to specific groups rather than blasting the same message to everyone.

Depending on the data you have, you can create segments by:

• Purchase history and product preferences
• Geographic location and timezone
• Customer lifecycle stage (new lead, active customer, lapsed customer)
• Engagement behavior (who opened your last campaign, who clicked, who did not)
• Demographics such as age group or job title

Segmentation is especially valuable when you consider that 73 percent of customers unsubscribe after receiving too many irrelevant messages. Sending the right message to the right group keeps your list healthy and your engagement rates high.

We also recommend A/B testing different channels alongside each other. Send the same campaign via email to one group and SMS to another, then compare open rates, click rates, and conversions. Each channel will deliver different results, and the data will tell you where to invest.

3. Personalize the message

It is easy to find services that send thousands of text messages to a list of phone numbers. But what makes SMS marketing significantly more effective is when each message is personalized for the individual recipient.

Basic personalization starts with addressing recipients by first name. Effective SMS personalization goes further:

• Behavioral triggers: Send messages based on specific customer actions, such as abandoning a cart, browsing a product category, or completing a purchase. Example: "Hi Sarah, you left something behind. Your cart is saved and ships free until midnight."
• Purchase history: Reference past purchases to make relevant offers feel earned rather than generic. Example: "Hey Chris, based on your last order, you might love our new lineup. 20% off with code RETURN20."
• Location-based: Use geographic data to send locally relevant offers or store-specific messages.
• Milestone recognition: Acknowledge birthdays, anniversaries, or loyalty milestones. Customers who receive birthday texts convert at significantly higher rates than those who receive generic promotional messages.

About 63 percent of marketers report higher conversions due to SMS personalization, and 49 percent of consumers say they are comfortable sharing data specifically to receive more personalized texts. With DailyStory, personalization tokens pull from your customer profiles automatically, so every message feels individual without requiring manual customization.

4. Time your delivery

Once you have crafted the right message, think carefully about when your recipient will receive it and whether they can act on it in that moment.

General timing guidelines based on industry benchmarks:

• Best days: Tuesday through Thursday consistently outperform other days for SMS engagement
• Best hours: Between 10 a.m. and 5 p.m. local time for the recipient. Mid-morning (10 to 11 a.m.) and early afternoon (noon to 2 p.m.) tend to produce the strongest click rates
• Avoid: Early mornings before 9 a.m., evenings after 8 p.m. (the TCPA prohibits marketing texts outside 8 a.m. to 9 p.m. local time), and Mondays, which typically see lower response rates across all marketing channels
• Match timing to the offer: A lunch promotion should go out at 10:30 a.m., not at 2 p.m. A flash sale should launch at the start of the day, with a reminder a few hours before it ends

Always schedule messages for the recipient's local timezone, not your own. Most SMS marketing platforms, including DailyStory, handle timezone-aware delivery automatically when timezone data is available in your customer profiles.

5. Track open rates, clicks, and conversions

Just as you would with an email campaign, you need to track the performance of your SMS messages to understand what is working and what is not. See our full guide on how to measure the success of your SMS marketing campaigns.

Key SMS metrics to track:

• Delivery rate: A healthy delivery rate is 95 percent or above. Rates below that usually point to list quality issues such as invalid numbers or poor list hygiene
• Open rate: Industry-wide, SMS open rates run 90 to 98 percent. If you are seeing significantly lower figures, your message content or sender name may be a factor
• Click-through rate (CTR): Industry average CTR for SMS is around 10 to 20 percent. Campaigns below 15 percent have room for improvement through better CTAs or more targeted segmentation
• Conversion rate: Well-optimized SMS programs achieve 21 to 30 percent conversion rates. Abandoned cart SMS in particular sees conversion rates of 24 to 39 percent
• Opt-out rate: A healthy list should see opt-out rates well below 1 percent per send. Rising opt-out rates are a signal that message frequency, relevance, or targeting needs adjustment

Use this data to A/B test different message versions, CTAs, and send times. Testing different elements can boost conversion rates by up to 20 percent. Review your analytics after every campaign and apply what you learn to the next one.

6. Understand SMS costs and character limits

While SMS is not expensive, there is a per-message fee for every text you send. Understanding how costs are calculated helps you optimize your budget, especially when sending at scale.

The original SMS specification limits messages to 160 characters using the standard GSM-7 character set. Telecommunication carriers still enforce this limit and charge per segment:

• Messages up to 160 characters: counted as one message
• Messages over 160 characters: split into multiple segments (typically 153 characters per segment), each billed separately
• Messages containing emojis, special quotation marks, or other Unicode characters: reduced to around 70 characters per segment, as Unicode uses more data per character
• US SMS pricing typically starts at approximately $0.015 per message segment

The practical advice: draft messages in plain text, count your characters before sending, and use a shortened URL for any links to preserve your character budget. Read more about how text message costs are calculated.

7. Include a clear call to action

Every text message you send should have one clear, specific call to action (CTA). With limited characters to work with, your CTA needs to be direct and frictionless. The easier you make it for a recipient to take action, the higher your conversion rate will be.

Effective SMS CTAs pair a strong action verb with a specific instruction and, where relevant, a sense of urgency:

• Show this text: "Show this text at checkout for 15% off your order today only."
• Click here: "Claim your 20% off coupon: [link]. Expires Sunday."
• Reply to enter: "Reply BLACK FRIDAY to claim your exclusive deal before midnight."
• Text-to-vote: "Text YES or NO. Your input shapes our next product."
• Buy now: "Text BUY and we will confirm your order and schedule delivery."

Coupling your CTA with genuine urgency, such as an expiry date or limited quantity, consistently improves click and response rates. Keep the message clear, short, and focused on a single action. See real SMS marketing examples for inspiration.

8. Think omnichannel

SMS is a powerful channel, but it works best as part of a coordinated omnichannel marketing strategy. Your customers interact with your brand across multiple touchpoints, and consistent, complementary messaging across those touchpoints outperforms any single channel on its own.

Practical omnichannel approaches include:

• SMS and email together: Use email for longer-form content and nurturing. Use SMS for time-sensitive nudges, reminders, or offers that require immediate action. The two channels reinforce each other
• Behavioral triggers across channels: If a customer abandons a cart, an immediate SMS reminder followed by an email with more detail is more effective than either message alone
• Two-way conversational SMS: 71 percent of customers now prefer the ability to text a business back. Enable two-way messaging so customers can ask questions, confirm appointments, or respond to surveys. Brands using two-way messaging report 85 percent faster response times and 60 percent higher customer satisfaction
• Watch for RCS: Rich Communication Services (RCS) is the next evolution of SMS, adding images, carousels, and interactive buttons to a text-like experience. With Apple adopting RCS in 2024 and an estimated 2.1 billion active RCS users expected by 2026, it is worth understanding how your SMS strategy will evolve as adoption grows

Use a platform such as DailyStory to build a connected strategy across SMS, email, push notifications, retargeting, and more. Reaching customers consistently across every channel they use is what turns one-time buyers into loyal advocates.
