Email Marketing Best Practices:
What to know in 2024

What you need to know to get your message in the inbox and stay out of the hot box.

Email marketing can be challenging, but we’ve made it easier by highlighting key best practices for 2024. Follow these essential strategies to optimize your campaigns, enhance deliverability, and engage your audience effectively.

Check, Recheck, and Check Again

We're all 1,000% better at catching errors in our emails after we hit send. Read your email out loud, test your emails for spam, test your emails in your inboxes, test your links, use a grammar plugin to check for spelling or grammar mistakes, check that you have the right list attached, and then do it all over again before hitting the send button.

No Link Redirects

Before adding a link to your email, you want to be sure to use the finalized or resolved URL. It's easiest to copy and paste the URL into a browser window (even better an incognito browser window) and let the browser resolve to the final destination first. Grab the resolved URL and use that for your email.

Focus On One Idea per Email

Focus on one idea, one thing, one topic, one problem, or one solution. Having multiple ideas reduces effectiveness and you'll lose your reader's attention.

Offer Upgrades to Active Customers Only

The most common mistake is to blast all subscribers with upgrade emails, even ones who have yet to try your product. 

Instead, focus on conversion first and only send upgrade emails to activate users already receiving value from your product. 

Sending upgrade emails to irrelevant users can hurt your brand.

Use Your Preheader

A preheader is the preview text for an email that sits right under the subject line before you've opened the email. Typically, you would put the first line of copy in the email, such as the email's header. Leaving this blank is losing out on valuable real estate at best. At worst, sometimes the preheader will be automatically filled with the first piece of copy the email provider thinks should go there... which is sometimes the code used to build the email in the back end (very bad and spammy look to a reader).

Tell Relatable Stories

Telling relatable stories impacts the reader and makes perfect email content. It's a perfect way to humanize your brand and earn trust. 

The most compelling stories come from life experiences. Look internally to share how you or your team use your service or product or look through past support tickets or customer interviews.

Design for Mobile First

Mobile has surpassed desktop for users opening their emails, so it's no surprise that you'll need to design your emails for mobile first. Buttons and links should be about the size of your thumb or between 44-48px squared. Fonts should be 16-22px. Any fixed widths should be 320px wide (the width of a phone screen) and adjust to 600-680px wide for desktops.

Avoid Spam Words in Your Emails

Certain words or phrases can land your email in the spam folder. 

It's best to avoid all of the following

Be Transparent and Consistent

Let your customers know when and how often to expect an email communication from you when signing up. If the customer expects a once-a-month communication but receives an email twice a week, chances are they might be irritated and want to opt out, report it as spam, or worse, you'll lose their trust.

Run A/B Testing

A/B testing is a strategic process that compares two versions of the same email against each other using a smaller list subsection to determine the better engagement performer. After the winner of the two versions is determined, the winning version is sent to the remainder of the list, yielding better engagement rates overall.

Segment Your List

The more segmented your lists are, the more personalized they are and the more relevant your content is. People are far less likely to unsubscribe from your list if they're always interested in what you have to say.

Avoid Using No-Reply

Ensure your emails are sent from a real email address. Using no-reply will decrease your sender's reputation since spam filters typically don't like them. It will also make the reader feel undervalued and give your brand a cold feeling.

Design for Dark Mode

Dark mode is becoming increasingly popular, and people choose dark mode for a few reasons: 

Regardless of the reason, dark mode is here to stay, and you should respect the user's preference by creating your emails with a fallback dark mode in your design. If you don't design it, the email service provider will do it for you, and it's not pretty. 

Here's a few things you can do: 

Practice Good List Hygiene

Removing inactive users from your main list has many benefits: 

An email list of 10,000 highly engaged subscribers can outperform an email list of 100,000 unengaged subscribers.

Keep these subscribers for your bigger marketing campaigns instead, such as Black Friday or Mother's Day. It's much harder to get new subscribers than it is to keep them, so give your subscribers what they want.

Never Purchase an Email List

Most emails in purchased lists are typically invalid, inactive, or a spam trap from the email service provider (ESP).

If the email address is a spam trap:

If the email address is valid and active

If the email address is inactive

Always Stay Compliant

The best practices above will help you reach more inboxes and keep people engaged with your content. But more importantly, you should always adhere to all the laws and regulations for email marketing, or any marketing, for that matter.
