Your SMS and email programs are stronger together. Unite them on the right platform to unlock higher engagement, conversions, and ROI than either can achieve alone.

Chances are, your audience is engaging with you on both email and SMS—additional data from our January 2026 Consumer Pulse shows that 93% of SMS subscribers also get emails. And while they expect different experiences on each channel, there’s significant value in coordinated messaging.

When brands strategically orchestrate their SMS and email programs, they see better engagement and conversions. In fact, our 2026 Marketer Pulse revealed that the more coordinated a brand's messaging program is, the more likely they were to see performance improvements since last year. 57% of consumers say they’re more likely to make a purchase when receiving the same promotion on multiple channels—though 73% want those follow-ups to add something new rather than repeating the same message.

But it’s not easy if you lack the resources, bandwidth, and tools to do it well.

Key Takeaways

SMS and email marketing are most effective when combined strategically on a single platform, not treated as separate channels. A coordinated approach drives higher engagement, conversion rates, and customer lifetime value.

Read on to discover:

• How combining email and SMS programs creates a complete view of each customer for better targeting and personalization
• The complementary roles email and SMS fill—and how to leverage their unique strengths
• How a coordinated approach extends your reach and improves engagement with multiple touchpoints
• How orchestration leads to a better customer experience and higher ROI

What is orchestration?

Orchestration is the purposeful coordination of marketing touchpoints across multiple channels—in this case, email and SMS within a single strategy. When done right, it helps brands reduce costs by sending subscribers messages on the right channel at the right moment, ensuring each touchpoint is relevant and engaging. This leads to better engagement, more revenue, and higher conversion rates.

Not everyone will want to subscribe to both channels—so figuring out how to speak to dual subscribers is important for creating seamless customer relationships.

What are the key differences between SMS and email marketing?

To unite SMS and email effectively, it’s helpful to understand the strengths of each channel.

SMS marketing is ideal for short messages and immediate impact

65% of text message subscribers say they usually see text messages from brands within 5 minutes of receiving a notification, making it perfect for time-sensitive messages like:

• Flash sales
• Price drops
• Low-stock notifications and back-in-stock alerts
• Order updates

SMS also gives shoppers a direct line to communicate with your brand if you enable two-way texting. One thing to keep in mind: sending messages too often can lead to fatigue and unsubscribes, so limit SMS marketing to 1–2 times per week.

Before you send promotional messages, both SMS and email require explicit consent from recipients under regulations like GDPR and TCPA. Transactional messages like order confirmations don't require explicit consent if they're related to a previous customer action.

Email marketing lends itself to longer, non-urgent content

Email gives you more room to go into detail about offers, product features, your brand story, and more. When we asked consumers which messages they want by email in our 2025 Consumer Trends Report, they leaned toward non-urgent content like:

• Loyalty or rewards updates
• Sales announcements
• New product launches
• Alerts for items I want
• Product recommendations
• Sneak peeks and behind-the-scenes content
• Helpful tips or educational content
• Reminders about items I viewed in my cart

The tradeoff: 63% of email subscribers say they open brand emails within an hour—but that's when they notice them. So the channel is best suited for content that isn't time-sensitive.

SMS vs. email marketing performance comparison

The cost of email and SMS marketing varies significantly depending on the tools you use, the volume of messages you send, and the features you need. When evaluating the effectiveness of your marketing efforts, it’s important to analyze performance across email and SMS campaigns, cross-channel campaigns, and other marketing channels.

How do SMS and email marketing work together?

When you bring SMS and email together on a unified platform, the channels complement each other to create a more effective marketing program.

1. They provide unified data across channels for better personalization when combined

Many shoppers have had multiple email addresses over time—whether to organize their inbox or to separate marketing messages from personal communication. In fact, most consumers maintain more than one email, and a significant portion even create dedicated addresses just for brand sign-ups. This behavior can make it difficult for marketers to maintain a consistent view of the customer.

Phone numbers, on the other hand, tend to remain much more stable. The majority of shoppers rely on a single mobile number, often keeping it for years. By connecting email and SMS programs, marketers can anchor customer profiles to this more persistent identifier—allowing them to unify data across channels. That way, even if a shopper updates or rotates their email address, their engagement history and preferences can remain intact through their phone number.

Unified subscriber data enables personalization that wouldn't be possible with siloed channels—letting you create more sophisticated segments, deliver more relevant content on each channel, and develop journeys that meet customers where they are.

2. They fulfill complementary roles in the customer journey

Consumers are open to receiving the same promotion across channels, but they want each message to feel like part of one continuous story—not a copy-paste. Think of it like a friend texting you the highlights of an event, then emailing you the full schedule. Each channel adds something the other can't.

For a product launch, use text to announce and drive instant traffic, then use email to tell the full story with more visuals—like suncare brand Supergoop! does in their campaigns.

For a cart abandonment flow, start with a text shortly after a subscriber leaves your site, then follow up with a more detailed email that addresses common purchase objections.

When Supergoop! switched to Attentive Email to consolidate with their existing SMS program, they achieved:

• 67% revenue-per-send growth from top-performing triggered messages
• 52% increase in unique open rates YoY for triggered messages
• 35% increase in click-to-conversion rate across key triggered messages

Attentive Email delivers a highly efficient solution for message management. Its unified platform streamlines communication efforts, while providing advanced control over multi-channel content. -Kim Nguyen, Senior Director, DTC & CRM, Supergoop!

3. They extend your reach and improve engagement when coordinated

By using both channels, you establish more opportunities to connect with subscribers based on their individual preferences and behaviors. Some check email more during the day and texts in the evening. Identifying these patterns lets you reach shoppers when they're most likely to engage.

Since multi-channel messaging increases likelihood to purchase, it's worth encouraging shoppers to subscribe to both by:

• Making subscription options clear in pop-ups, landing pages, and footers
• Communicating the value of each channel
• Offering an incentive to subscribe to both
• Promoting each channel to single-channel subscribers

4. They drive higher conversion rates and improve ROI together

Subscribers who receive both SMS and email are 2.4x more likely to buy than those who receive SMS alone. With both channels on the same platform, you can prevent duplicate messages to subscribers who've already converted, create sequential journeys, and prioritize the channel each subscriber is most likely to engage on.

L'Occitane puts this into practice with their session abandonment journey: a text 15 minutes after a site visit, followed by a more detailed email an hour later if the subscriber hasn't returned. The result: a 382% increase in conversions.

Customer journey mapping for SMS and email marketing

Customer journey mapping helps you visualize the entire path customers take—from awareness to conversion—and pinpoint the best moments to reach them on each channel. For example, you might launch a promotional email to introduce a new product, then follow up with SMS messages offering exclusive discounts or timely reminders.

Effective mapping relies on customer data and analytics to tailor your campaigns to specific needs at each stage, creating communications that build trust and drive engagement over time.
