How Long Should an Email Be?

We analyzed emails from the top marketing experts to find out how long your email should be.

Nearly every business with an email marketing strategy wonders how to write the perfect email. They question the length of their emails. (Short or long?) They wonder how they can get more people to open their emails. 

And there isn’t a simple answer to these questions — until now.


With the help of AWeber’s data scientist, we analyzed 1,000 emails from 100 of today’s top marketers. Our goal? Gather email marketing statistics that will answer how long an email should be.

The 100 experts we analyzed are the best of the best. Their email strategies engage thousands and drive millions in revenue. Many of them see unheard of results (like 80% open rates and 30% click-through rates).

The average email length

Of the 1,000 emails we analyzed, we found that emails have 434.48 words on average. 434 words takes approximately 3.3 minutes to read.

Why some pros go with shorter emails

However, more than 50% of the emails we analyzed contained 300 words or less (a 2.3 minute read time). With people receiving more emails than ever before, it makes sense that experts are sending shorter emails. Email marketers need to stand out to captivate their readers. Short emails might be a good strategy for doing so.

Henneke Duistermaat is the founder of Enchanting Marketing and one of the 100 top marketers whose emails we analyzed. She often sends emails with less than 300 words.

“Have you ever heard someone complaining they’re not getting enough email? Everyone’s inbox is overflowing. We’re all time-starved. So, we love succinct messages that help us make a quick decision: whether to reply or not, whether to click through or not”

Why some pros send long-form emails

Yet, 24.1% of the emails we analyzed contained 601 words or more. And 11.4% of them had more than 901 words, a read time of approximately 6.9 minutes.

These experts stand out by sending long emails packed with valuable content, like Ann Handley. Handley is the Chief Content Officer at Marketing Profs, a marketing education company, and one of the top 100 marketers we included in our research. 

She sends her newsletter TotalAnnarchy via AWeber every other Sunday. On average, her newsletters contain 1,838.5 words, which takes roughly 14 minutes to read.

“It’s not that long-form emails are effective. Rather, what’s effective is emails that have value for the people on your list. I don’t set out every other Sunday with a goal of writing the longest email I possibly can. But I do have a goal of writing an authentic, valuable, fun letter to each and every subscriber on my list. I put my heart and soul into it, and that’s why people respond.”

Matt Kepnes, author and founder of travel blog Nomadic Matt, is also on our list of top marketers. He sends long-form emails as well. On average, they contain 802 words. Instead of linking off to posts on his blog, he includes entire articles within his emails. These messages see high open and click-through rates.

“People will read longer emails if the topic is important enough.”

How to choose your email length

So how do you decide whether to send short or long emails? 

It depends on your unique business goals, according to Andy Crestodina, a top email marketer and the founder of website consulting company Orbit Media.

“If your goal is simply awareness, long or short is less important. If subscribers see it, like it, smile, you met the goal! If your goal is traffic, then give the recipient the minimum amount of information needed to decide to click. The CTR (click-through rate) is everything and more text just means more noise in their inbox.”

A/B Split Test

Our recommendation is to test. Your email length strategy should be based on data. So perform an A/B split test to see what length email performs best with your subscribers. 

Email length guidelines

So where do you start? The one common theme we got from all our marketing experts is your email needs to provide value to your readers. If you can say the same thing with less words, then do so.

You shouldn’t be too concerned about making sure your emails fall within a certain word count. Bottom line is if your emails contain valuable content or offers, your subscribers are going to want to read your email despite the length.

You may also find the length of your email varies by the type of emails you’re sending. Here are three types of emails and some guidelines you can follow:

Email newsletter

Your email newsletter length could end up be your longest. Why? Because you have a lot of content to share. But don’t overshare, your goal with a newsletter should be driving traffic to your website or landing page.  

The key to a good newsletter length is to keep each section brief. Check out this example of our weekly newsletter. Overall the email is long, but each section only has 2 paragraphs each. To read more of the content, you need to click to our website.

Promotional email

I would recommend keeping your promotional email’s short. Use images and a strong headline to help communicate your offer. Get to your offer quickly.

Here’s a great example from Grubhub. This email only contains 3 sentences. They’re trying to drive an action based on the image, exclusive offer, and call to action.

Welcome email

Your welcome email could be short or long format, it really depends on how much information you want to share with your new subscribers.

Here are two examples that show both a shorter version and longer version, that both work.
