With new apps, endless updates, and a never-ending stream of information on marketing your business, one tool continues to stand out: email marketing.

Even in 2024, email marketing continues to be an essential part of any strategy for businesses looking to connect with their audience.

Need convincing? Let's explore the pivotal stats shaping the email marketing landscape this coming year. 

General Stats 

Worldwide Email Users Are Expected to Increase to 4.6 Billion by 2025

As it stands, there will be over 4.3 billion people who use email in 2023

This stat is only expected to increase in the coming years, with email connectivity increasing to 4.6 billion by 2025.

347.3 Billion Emails are Sent and Received Every Day  

This number is projected to increase to 361.6 billion in 2024

Experts used to think that email would fall by the wayside as apps like WhatsApp and Slack emerged onto the scene, but with worldwide internet accessibility increasing overall, we are seeing quite the opposite. 

Open Rate Stats 

Personalized Emails Have An 82% Higher Open Rate Than Generic Emails 

Personalization used to be a tactic that seemed more optional than essential, but the stats show that in order to stay competitive, businesses need to lean into personalizing their emails.

Welcome Emails Have An Open Rate of 91.43%

If you don’t have welcome emails set up yet, then stop what you’re doing and get started. These emails grab attention with the highest open rate and deliver a high payoff with an average click-through rate 4 times higher than your regular marketing email at 26.9%.

The Average Open Rate For Email Campaigns is 21.33%

This varies depending on your industry and target audience, but a “good” email open rate should fall between 17-28%

The industries with the highest open rates are government, religious, hobbies and marketing. 

Engagement Stats 

60% of Consumers Have Completed a Purchase Through Marketing Emails 

A great email marketing campaign captures attention and drives action. The latest stats show consumers spend 138% more when influenced by effective email marketing strategies.

77% of Marketers Have Seen An Increase In Email Engagement Over The Last 12 Months

Remember, this isn’t a guarantee with email marketing campaigns. You still need to use best practices like segmentation, strong subject lines, eye-catching images, clear and concise copy and a strong call to action. You aren’t the only one hitting your target’s inbox, so make sure you stand out. 

64% of People Decide Whether To Open Or Delete Emails Based On Subject Lines

Grab your recipient's attention with a catchy subject line, or it will end up in the trash — or worse, they’ll report it as spam.

Mondays And Tuesdays Are The Best Days To Send Marketing Emails 

The highest open rate of emails is on Mondays, but the highest click-through rate happens on Tuesdays. 

The Best Time To Send An Email Is Between 9 am and 11 am

If you’re not a morning person, the best alternative is between 1 pm and 2 pm.

Marketing Emails Have A ROI of $36 For Every $1 Spent

The return on investment for email marketing is higher than any other channel. 

Stats like these are great, but if you don’t understand how to use them, how will you improve your next marketing campaign? That’s why tracking your success is so important.

6 Ways To Optimize Your Campaigns

Set up Automated Email Campaigns 

These perform the best because they are timely, relevant and personalized to your subscribers. 

Email Triggers: 


Welcome emails are set up so people will receive an email right after they hit subscribe. It’s common to offer new subscribers small coupon codes because they have a higher chance of converting — you already know they want to know more about your product! 

New Customer

Send a thank you message to people who made a purchase. It's a nice gesture, and you can offer things like customer service to encourage a positive buying experience. 

Abandoned Cart

Your product has already tempted these potential customers, which is why open rates for abandoned cart emails are over 48%! Why not send them a reminder? 

Browse History 

Like abandoned carts, these emails are sent to people who viewed products on your site but weren’t ready to check out. It’s a bit of an aggressive approach IMO — like a digital pushy salesperson — but they can lead to a purchase! 

Customer Winbacks

These emails are sent to people who have shopped with you but haven’t engaged in a while. Typically, selling to someone who has already purchased from you is easier. Companies often offer discount codes to return or let them know about a sale on a product they’ve already purchased. 

Segment And Personalize Your Email Lists 

It’s the same rule for social media followers and email subscribers. Quality over quantity. Not everyone on your list will be interested in the same generic content. Segmented and targeted emails generate 58% of all revenue

Make sure you add people’s names and segment based on things like location - ex “windchill special for my Winnipeg followers!” 

Pro-Tip: Consumers are tuned in and hold lofty expectations regarding personalization. Make the extra effort to ensure your personalization techniques meet the mark—and then double-check to be absolutely certain. 

It’s important to use the segmenting tools along with your personalization efforts to avoid annoying your customer with things like:  

  • Expired offers 
  • Wrong location offers 
  • Already purchase promotions 
  • Recommendations that don’t match their interests 

Optimize For Mobile And Desktop 

You want to make sure your potential customers are having an easy experience. Optimized emails don’t give any reason for people to click out of your content. 

Avoid Sending Too Many Emails 

Engagement drops with each additional newsletter sent per week.

Create Dark Mode Compatible Emails 

35% of email opens were tracked using dark mode in 2022. Making emails dark mode-friendly is allows a more comfortable reading experience, cutting down on blue light and screen glare. 

Optimize for dark mode by using transparent PNGs, adding translucent outlines to dark text PNGs, and always test emails before hitting send. 

Make sure your emails look good in both light and dark modes, keeping things accessible and aligned with what your subscribers prefer for a smooth experience.

Add Interactive Elements 

Interactive emails boost engagement and conversions by creating a more personalized experience. 

Using elements like countdown timers, GIFs, ratings, quizzes, surveys, videos, and polls encourages active participation, leading to higher open rates and engagement. With increased attention and engagement, interactive emails drive higher click-through rates, leading to increased conversions.

We love an email marketing campaign because it offers a direct and personalized way to engage with your audience, build relationships, and drive conversions. 

With the power of well-crafted email campaigns, businesses like yours can effectively reach their target market and achieve their marketing goals.
