Email & SMS Marketing Best Practices to Drive Engagement and Sales

In today’s hyper-connected world, your prospects don’t just expect communication—they expect relevant, timely, and personalized messages that show up exactly where they are. That’s where email and SMS marketing shine.

Done right, these channels can dramatically boost engagement, improve customer retention, and increase sales. But without a strategy, they can just as easily become noise—or worse, spam.

Here are the best practices you need to create high-converting email and SMS campaigns that get results.

1. Segment Your Audience for Relevance

Not every subscriber should receive the same message. Segmentation allows you to tailor your content based on factors like:

• Purchase history

• Demographics

• Engagement level

• Funnel stage

• Website behavior

By sending more targeted messages, you increase open rates, click-through rates, and overall campaign performance.

2. Craft Clear, Compelling Messaging

Your subject lines, headers, and CTAs need to work together to draw your audience in and prompt action.

For email:

• Use short, curiosity-driven subject lines (aim for under 50 characters)

• Make the body copy skimmable—use bullet points and short paragraphs

• Include a single, clear CTA button

For SMS:

• Get straight to the point—160 characters or less

• Use personalization when possible (e.g., “Hi Sarah!”)

• Always include an opt-out option (compliance isn’t optional!)

• 

3. Optimize Send Timing for Maximum Impact

Timing matters just as much as content. Your audience is more likely to engage when messages arrive at the right moment.

Best practices:

• Test send times by audience segment

• For B2C, evenings and weekends may perform better

• For B2B, mid-morning or early afternoon on weekdays often works best

Use automation to trigger emails and texts based on user behavior (like cart abandonment or lead magnet downloads)

4. Balance Frequency and Value

Email and SMS are personal inboxes—overuse them, and you’ll quickly lose trust. But underuse them, and you miss opportunities to connect.

Guidelines:

• Focus on providing value with every message (education, offers, updates)

• Don’t send daily messages unless the audience explicitly signed up for that frequency

• For SMS, 2–4 messages per month is often ideal

• Allow subscribers to set their own preferences

The key is consistency with purpose, not just presence.

5. Design for Mobile First

Most emails and nearly all SMS messages are read on mobile devices. If your design doesn’t render well on a phone, your message could be ignored or deleted.

Tips for mobile-friendly email design:

• Use a single-column layout

• Keep font sizes readable (at least 14px)

• Make CTAs thumb-tappable

• Keep image sizes optimized for fast loading

Test your campaigns on multiple devices before hitting “send.”

6. Use A/B Testing to Improve Results

Data should drive your strategy. A/B testing allows you to test variables like:

• Subject lines

• CTA copy

• Send times

• Message length

• Visuals or emojis

Track key metrics (open rates, click-through rates, conversions) and make iterative improvements based on performance.

7. Stay Compliant with Regulations

No matter how great your message is, if it violates privacy regulations, it could cost you more than just a lost subscriber.

Be sure to comply with:

• CAN-SPAM Act (U.S.): Requires clear opt-out instructions, sender info, and truthful subject lines

• TCPA (for SMS): Requires express written consent before sending messages

• GDPR (EU): Requires consent and gives users control over data

Always include clear privacy policies and honor opt-out requests promptly.

8. Automate Intelligently

Automation saves time—but it should never feel robotic. Use workflows to create smart, behavior-based messaging that adapts to how each lead interacts with your brand.

Examples:

• Welcome email sequences

• Post-purchase follow-ups

• Abandoned cart SMS reminders

• Re-engagement emails for inactive users

The goal is to keep the conversation going—without lifting a finger after setup.
