15 Best email marketing strategies to increase engagement and sales

The best email marketing strategies help you reach the right people with the right message at the right time. A thoughtful approach can turn new subscribers into loyal customers and keep existing ones coming back.

In this guide, you’ll learn 15 types of email marketing strategies for growing your email list, creating relevant campaigns, improving engagement, and measuring results so every email supports your marketing goals.

Build a high-quality email list

An email list is a collection of people who have given you permission to contact them through email. A high-quality email list is made up of subscribers who genuinely want to hear from your brand and are more likely to open your emails, click your links, and become customers.

These strategies will help you attract the right audience instead of simply collecting more email addresses.

1. Create sign-up forms people actually want to use

The easiest way to grow your email list is with simple sign-up forms that clearly explain what people will receive and why it’s worth subscribing.

Keep your forms short and only ask for information you’ll actually use. An email address is essential, while a first name can help you create more personalized communication later. Depending on your business, you might also collect preferences such as product interests or location to send more relevant emails.

Your website is usually the best place to collect subscribers. Add embedded sign-up forms to your homepage, blog posts, and checkout page, and use a pop-up with a compelling offer such as a first-order discount, exclusive content, or early access to new products.

Important note

Always collect email addresses with permission and follow the privacy laws that apply where you do business, such as CAN-SPAM in the United States or GDPR in the European Union. Include a clear unsubscribe link in every marketing email and make it just as easy to leave your list as it is to join. This builds trust, reduces spam complaints, and protects your sender reputation.

2. Segment subscribers from the start

Grouping subscribers based on shared characteristics helps you send relevant content to the right people instead of the same email to everyone. For example, an online store could send exclusive promotions to existing customers, welcome offers to new subscribers, and educational content to people who have not made their first purchase yet.

Start with simple segments that match your business and target audience. You can group subscribers by how they joined your list, the products or topics they’re interested in, their location, or where they are in the customer lifecycle. As your email marketing program grows, you can refine your segments using user behavior and past purchases.

3. Focus on quality over quantity

Subscribers are more likely to stay engaged when every message offers something useful, whether that’s helpful tips, product updates, or exclusive promotions. Sending too many emails can overwhelm your audience and increase unsubscribe rates.

For most B2C businesses, one email per week or two to four emails per month is a good starting point. If you have frequent product launches or seasonal campaigns, you can send emails more often as long as each one provides clear value.

It’s also good practice to let subscribers choose how often they want to hear from you. The Slow Label’s subscribers can choose between receiving all news and updates or only hearing from the brand during launches and restocks. Giving people control over email frequency sets clear expectations and can encourage them to stay subscribed longer.

Send the right email at every stage of the customer journey

Every subscriber goes through a customer journey, from discovering your brand to making a purchase and becoming a loyal customer. Email automation helps you use email marketing effectively by sending the right message at each stage, keeping your communication relevant, and giving subscribers a reason to stay engaged.

4. Welcome new subscribers with a strong first impression

A welcome email marks the beginning of the customer journey and is your first opportunity to build trust with a new subscriber. It sets expectations for future communication and encourages people to stay engaged with your brand.

Set up your welcome email to send automatically as soon as someone joins your email list. Sending it immediately confirms their subscription and delivers value while your brand is still top of mind.

Include whatever you promised in your sign-up form, whether that’s a discount code, exclusive content, or another incentive. Tort, for example, welcomes new subscribers with a friendly message along with the promised promo code.

5. Use promotional campaigns strategically

Balance promotional messages with valuable content, so subscribers have a reason to stay engaged between sales. Use sales and special offers with purpose, and focus on showing why your products are worth buying.

Time promotional messages around product launches, seasonal events, or exclusive promotions when subscribers are most likely to take action. Keep each email marketing campaign focused on a single offer with a clear call to action. This makes it easier for subscribers to understand your message and decide what to do next.

6. Recover lost sales with triggered emails

Triggered emails are sent automatically when someone takes a specific action. One of the most effective examples is an abandoned cart reminder, which encourages shoppers to return and complete their purchase after leaving your checkout without buying.

Send the first reminder within a few hours of cart abandonment while the products are still fresh in the shopper’s mind. If needed, follow up with one or two more reminders over the next few days. Sending too many emails can feel intrusive, so keep the sequence short and stop once the customer completes their purchase.

VLDL Shop makes returning to the checkout effortless by displaying the abandoned items in the email alongside a prominent button that takes shoppers straight back to their cart. The fewer steps customers need to take, the more likely they are to complete their order.

7. Strengthen customer loyalty after the purchase

The customer journey doesn’t end after a sale. Post-purchase follow-ups help customers get the most out of their order and encourage repeat purchases.

Send a thank you email after every purchase, then follow up with content that matches the product or customer. This could include care instructions, product recommendations based on purchase history, or a request for a review once the order has arrived.

8. Re-engage inactive subscribers before removing them

Keeping your email list up to date includes removing inactive subscribers. Before doing that, send a re-engagement campaign to put your brand back on their radar.

A good time to trigger this email marketing campaign is after 60 to 90 days of inactivity, though the timing depends on how often you normally send marketing emails. Remind subscribers what they’re missing, share relevant content or new products, or offer an incentive to come back.

Create relevant, personalized email campaigns

Relevant emails are more likely to capture attention than generic ones. These email campaign strategies will help you create personalized content that matches your audience’s interests and actions.

9. Personalize emails with customer data

Personalized content goes beyond adding a subscriber’s first name. Use customer data to tailor your emails based on browsing activity, wishlist items, preferred product categories, or how people interact with previous emails. These insights help you send targeted messages and relevant communication that match each subscriber’s interests.

Only collect and use data that subscribers have agreed to share. Be transparent about how you use their information, follow applicable privacy laws, and give people an easy way to update their preferences or withdraw consent. Respecting customer privacy builds trust and supports long-term customer relationships.

10. Create emails that solve customer problems

Think about why someone joined your email list in the first place. New subscribers may be looking for product information, while existing customers often appreciate practical advice, inspiration, or recommendations that help solve common pain points and get more from their purchase.

A print-on-demand store that specializes in apparel, for example, could send care instructions after a purchase, share styling ideas for different seasons, or recommend matching products based on previous orders.

Creating relevant content around those needs keeps your emails useful and strengthens customer relationships over time.

Write emails people actually open and click

Even the best email marketing campaign can fall flat if people never open it or click through. The next strategies focus on the elements you can control, from writing stronger subject lines to creating clear, action-focused emails that are easy to read on any device.

11. Craft compelling subject lines

Your subject line is the first thing subscribers see in your email, so it should capture their attention immediately. A good email subject line is short, specific, and focuses on one clear benefit. When appropriate, personalize subject lines with a subscriber’s name, location, or interests, but only if it feels natural and relevant.

Avoid clickbait or misleading claims. Keep your subject lines under 60 characters so they display properly on most devices, and limit punctuation to three marks or fewer to avoid making your emails look spammy.

Here are a couple of good examples:

• Your favorite hoodie is back in stock

• Three skincare tips for dry winter skin

• Save 20% on your next weekend getaway

• Five shortcuts to speed up your workflow

12. Write concise emails with clear calls to action

A concise email is easier to read and makes the next step obvious. Focus on one message and one action instead of trying to promote multiple offers at once. This reduces distractions and can improve click-through rates.

Your call to action should clearly tell subscribers what to do next and match the purpose of the email. For example, use Shop the collection for a product launch, Read the article for educational content, Complete your order for an abandoned cart reminder, or Leave a review after a purchase.

Place the button or link where subscribers can easily find it, especially on mobile devices, where people tend to scan emails quickly.

Optimize your email marketing efforts

The best email marketing strategies evolve over time. Regularly optimizing your email marketing efforts helps you improve performance, adapt to changing customer behavior, and get more from every campaign.

13. Protect your sender reputation

Your sender reputation affects whether your emails reach subscribers’ inboxes or end up in the spam folder. A good reputation takes time to build but can be damaged by poor email practices.

Protect your sender reputation by following these best practices:

• Verify your sending domain: Authentication methods such as SPF, DKIM, and DMARC help email providers recognize your messages as legitimate.

• Remove invalid email addresses: Regularly clean your email list to reduce bounces and avoid sending emails to inactive or nonexistent accounts.

• Check for broken links: Test every button and link before sending an email. Broken links create a poor experience and can reduce trust.

• Honor unsubscribe requests: Process opt-out requests promptly instead of continuing to send marketing emails to people who no longer want them.

14. Monitor key metrics and keep testing

One of the keys to a successful email marketing strategy is regular testing and improvement. Tracking your results helps you understand what works and where your email marketing campaign strategy needs improvement.

While performance varies by industry, these benchmarks from Mailchimp can help you evaluate your email campaigns:

• Average open rate: 35.63%

• Average click-through rate: 2.62%

• Average unsubscribe rate: 0.22%

• Average hard bounce rate (due to permanent issue): 0.21%

• Average soft bounce rate (due to temporary issue): 0.70%

If your results consistently fall below these averages, test one change at a time instead of overhauling your entire strategy. A/B testing compares two versions of the same email by changing a single element, such as the subject line, call to action, send time, or layout, to see which version performs better.

Small improvements over time can lead to more effective email marketing campaigns and stronger results in future efforts.

15. Choose a reliable email marketing platform

Managing email campaigns manually becomes more difficult as your subscriber list grows. A reliable email marketing platform can simplify many of the strategies covered in this guide, including email automation, A/B testing, campaign performance analysis, and tools that help protect your sender reputation.

Most email service providers also include user-friendly tools for list segmentation and marketing automation, making it easier to deliver the right message at the right time. Popular options include Mailchimp, Klaviyo, HubSpot, and Kit. Compare their features, pricing, and integrations to find the platform that best fits your business and marketing channels.
