7 Email Best Practices to Boost Your Open Rates and Drive Engagement

Let’s face it—email marketing can be tough. You spend time crafting the perfect message, only for it to sit in your audience’s inbox, gathering digital dust. Sound familiar? The truth is, your email could be a goldmine of value, but if it’s not getting opened, none of that matters. That’s why boosting your open rates is the name of the game.

Whether you’re sending out newsletters, product updates, or event invitations, higher open rates directly translate to more eyes on your content, more clicks, and, ultimately, more engagement. In this guide, we’ll walk you through 7 best practices to help you craft emails that practically beg to be opened.

Let’s get started!

1. Crafting Irresistible Subject Lines

The subject line is the first thing your recipient sees—and we all know first impressions count! It’s the gateway to your email, and if you don’t hook them here, it’s game over.

So, what makes a subject line irresistible? It needs to be short, engaging, and personal. According to studies, subject lines between 40 and 60 characters tend to get the best open rates. But it’s not just about length—it’s about tone. People want to feel like you’re talking directly to them.

Here are a few strategies you can try:

  • Personalise your subject lines: Using a recipient’s first name can grab attention. For example, “Tom, check out this limited offer just for you!”
  • Create urgency: Words like “Today only” or “Don’t miss out” create a sense of urgency that encourages immediate action.
  • Spark curiosity: “You won’t believe what we have in store…” leaves just enough mystery to tempt the reader to open.

Oh, and avoid those dreaded spammy words like “free” or “guaranteed.” No one wants to feel like they’re about to open junk mail.

2. Building Trust with Your Sender Name and Address

Imagine receiving an email from “[email protected].” Would you open it? Thought not. People are more likely to open an email if they trust the sender.

Make sure your sender name is recognisable and consistent. This means using either your company name or a familiar individual within your team. And while you’re at it, use a real email address that accepts replies. Emails from “do-not-reply” addresses feel impersonal, and people like to know they can interact with you.

A tip here: try using a combination of your company name and a person’s name, such as “Sarah from Energy Cell.” It adds a human touch, which makes people feel like they’re hearing from a friend rather than just another faceless business.

3. Timing is Everything: When to Send Emails

You can have the best subject line in the world, but if you’re sending it at the wrong time, it might still get lost in the shuffle.

Timing plays a crucial role in your email open rates. But here’s the catch—it’s not one-size-fits-all. Your audience might be more active at specific times, so you’ll want to experiment with your send times. That said, some general trends can give you a head start:

  • Weekday mornings: Tuesday, Wednesday, and Thursday between 9 AM and 11 AM tend to yield higher open rates across many industries.
  • Avoid Mondays and Fridays: Mondays are chaotic, and by Friday, people are clocking out mentally, so your emails could get overlooked.
  • Test, test, test: Try different times and see what works for your audience. You might find that your subscribers are night owls, and sending them later in the evening gets better engagement.

The key here is to know your audience’s habits and meet them where they are.

4. Segmenting Your Audience for Better Results

Not all your subscribers are created equal, and they shouldn’t all receive the same email. This is where segmentation comes into play, and it’s an absolute game-changer for your open rates.

By dividing your email list into specific groups—based on behaviour, demographics, or purchase history—you can deliver more relevant content. The more tailored your emails, the more likely people are to open them. It’s the difference between “We have a great offer” and “Tom, here’s a special offer based on your recent purchase.”

Here are some ways to segment your list:

  • By engagement level: Send re-engagement campaigns to inactive users and exclusive offers to your most loyal customers.
  • By demographics: Age, location, or profession can all be factors that affect what kind of content resonates with your audience.
  • By behaviour: Tailor your emails based on recent purchases or website activity.

When your emails feel personal and relevant, open rates naturally climb.

5. Optimising Email Content and Formatting

Now that they’ve opened your email let’s keep them engaged. Your email’s design and content should be easy to read and visually appealing. People are busy, and long blocks of text are an instant turn-off.

Some tips for optimising your content:

  • Keep it scannable: Use bullet points, short paragraphs, and headings to break up text.
  • Make it mobile-friendly: More than half of emails are opened on mobile devices, so make sure your design looks great on small screens.
  • Use strong CTAs: Whether it’s “Shop Now,” “Learn More,” or “Sign Up,” your call to action needs to stand out and be crystal clear.

Also, don’t underestimate the power of your email preview text—that’s the snippet that appears next to or under the subject line in an inbox. Use it wisely to offer a sneak peek of the email’s value.

6. Keeping Your Email List Clean

A clean email list equals better open rates, plain and simple. Keeping inactive or unengaged subscribers on your list can hurt your deliverability and skew your metrics.

Here’s how to keep your list healthy:

  • Regularly prune inactive users: Every few months, remove people who haven’t opened your emails in a while. It’s better to have a smaller, engaged list than a large, inactive one.
  • Use re-engagement campaigns: Before removing users, try sending them a targeted email to re-engage them.
  • Offer easy opt-outs: Make it simple for people to unsubscribe if they’re no longer interested. Keeping disinterested users only hurts your engagement.

7. Ensuring Deliverability and Avoiding Spam Filters

Finally, the best email in the world won’t help your business if it ends up in the spam folder. So, how do you stay out of the dreaded spam box?

Here are a few deliverability tips:

  • Avoid spammy language: Words like “Buy now” or “Limited time offer” can trigger spam filters.
  • Authenticate your emails: Use tools like DKIM, SPF, and DMARC to authenticate your emails and boost your reputation with email providers.
  • Test before sending: Use tools to check your emails for spammy elements and preview how they’ll look in different inboxes.

Following these steps will keep your emails in the inbox where they belong.
