Tips to Boost Email Engagement and Increase Open Rates

Emails are a great way to connect with your customers and subscribers, but let’s face it—low open rates, barely-there click-throughs, and those dreaded unsubscribes can be frustrating. If you’re dealing with this, you’re definitely not alone. The good news? You can turn things around.

This guide is here to help you boost your email engagement with simple, actionable tips. By the end, you’ll have a better strategy for creating emails your customers won’t be able to ignore.

Why Email Engagement Matters

Email engagement measures how your audience interacts with your emails—whether they’re opening them, clicking links, or replying. High engagement rates show your emails are resonating, and email service providers (ESPs) use this as a signal to keep delivering your emails to inboxes instead of junk folders.

But if your open or click rates are low—or you’re seeing more unsubscribes and bounces—it’s time to rethink your strategy. The good news? With tools like AI-powered email assistants and solid analytics, boosting engagement isn’t just doable—it’s trackable too.

Understanding Engagement Metrics (and Apple's MPP Update)

An open rate of 20-30% used to be considered pretty solid for most industries, with click-through rates (CTR) usually sitting around 2-5%. However, since Apple rolled out Mail Privacy Protection (MPP) in 2021, open rates have become less reliable. Why? MPP marks emails as “opened” even if the user hasn’t actually done so.

So, instead of relying on open rates, it’s time to focus on metrics that really matter—like CTR, bounce rates, and replies.

Wondering how to boost these engagement metrics? Let’s break it down.

Strategies for Boosting Email Engagement

1. Make Your Emails Personal and Relevant

Think about what you’d want to see in your own inbox. Generic, one-size-fits-all emails are easy to ignore, but ones that feel tailored to your interests or needs? Those grab attention.

Break your audience into smaller groups based on things like behavior, location, interests, or purchase history. For instance, if you’re an e-commerce brand, send loyal customers special discounts, and new shoppers welcome offers that match their interests.

Make it personal by adding their first name to the subject line, suggesting products based on what they’ve browsed, or showing deals that match their location or age group.

Share helpful, engaging content—like tips, guides, or exclusive insights—that builds trust and makes your emails worth opening.

By staying abreast of the latest news and trends, you can create timely content that resonates with your audience. Newsjacking, or the practice of aligning your content with current events, can significantly boost your engagement rates.

2. Keep It Clean - Email List Hygiene

A clean email list is the key to better engagement and a solid sender reputation. Here’s how to stay on top of it:

Cut out those who haven’t engaged in a while by setting a “sunset policy”—like removing anyone who hasn’t opened an email in six months. This boosts your open rates and helps avoid spam complaints.

Never buy email lists. Not only is it risky, but it can hurt your sender reputation and lead to more bounces. Stick to growing your list the right way—through opt-ins.

Regularly check for outdated or incorrect email addresses. Tools like email validation software make this super easy.

Your subscribers’ inboxes are packed, so how do you stand out? Simple—offer value.

3. Make Sure Your Emails Are Authenticated

Email authentication helps providers trust that you’re a legit sender, so your messages don’t get flagged as spam. Here’s what to use:

Make sure your emails are sent from approved servers.

Confirms your emails haven’t been tampered with along the way.

Combines SPF and DKIM for extra protection while using DMARC to tell receiving mail servers how to handle messages that fail authentication. DMARC also generates detailed reports to help identify authentication issues and detect malicious activity, building trust with email providers.

4. Keep an Eye on Blacklists

ESPs pay close attention to sender reputations, and a bad domain or IP reputation can get you blacklisted.

How to Check for Blacklists

  • Tools like MXToolbox make it easy to check if your domain or IP has been flagged. Being on a blacklist can seriously hurt your email deliverability.

What to Do If You’re Blacklisted

  • Step up your sending practices and reach out to blacklist admins to get removed.

5. Craft Great Headlines & Previews

Your subject line and preview text are the first things people notice—make them count!

Stick to subject lines under 50 characters that grab attention and spark curiosity.

“How to Save 30 Minutes Every Morning ☕” is way more appealing than “Time Management Tips.”

Try out different subject line versions to see what resonates best with your audience.

6. Make It Simple to Opt-In and Out

A smooth experience goes a long way.

Make your sign-up option easy to find and encourage users to join with perks like discounts or free resources.

Nobody likes feeling spammed. Adding an unsubscribe button not only keeps you compliant with regulations like CAN-SPAM but also shows you respect your subscribers’ choices.

Before you hit “send,” ask yourself, “Would I forward this to a friend?” If the answer’s no, it's time for edits.

7. Use Insights from User Behavior

Pay attention to how people engage with your content so you can make it even better. Analytics tools can help you figure out what’s working and what’s not:

A high bounce rate might mean it’s time to clean up your email list.

See which links are getting the most clicks and tweak your future campaigns to match.

If more people are unsubscribing than usual, it’s worth rethinking your content, how often you’re sending emails, or who you’re targeting.

8. Put Value First

Your subscribers’ inboxes are packed, so how do you stand out? Simple—offer value!

  • Share helpful guides, discounts, or industry tips to show you’re more than just another sales email.

  • Make them feel special with early access to products or services, creating a little FOMO to boost engagement.

9. Be Human, Not Annoying

Sending emails too often is a quick way to lose subscribers. Test your timing and stick to a schedule that gets good engagement without overwhelming your audience.

Add some storytelling or humor to let your brand’s personality shine through. Your emails should feel more like a friendly conversation than a sales pitch.

Here’s a simple rule: before you hit “send,” ask yourself, “Would I forward this to a friend?” If the answer’s no, it’s time for edits.

Email isn’t just a tool—it’s your connection to your audience. Focus on personalization, keeping your lists clean, and sharing content that matters, and you can take your email campaigns from “meh” to amazing.

Start by reviewing your current email strategy. Test different approaches, track your results, and tweak your plan as you go. With a bit of effort and the right techniques, you’ll grow a loyal audience that actually looks forward to hearing from you.

And don’t forget—the secret to standing out is offering real value. Be the email your subscribers love to open, not the one they ignore.
