Optimum character length for email marketing subject lines is a thing of some contention. Recent studies by MailerMailer and Informz found that shorter subject lines clearly had the best open rates. However, MailChimp’s 2012 study of more than 12 billion emails suggested that there was no strong correlation between subject line length and open rates, and that quality and not quantity was the key.

Are longer or shorter subject lines best?

Are longer or shorter subject lines best?

What is clear is that optimum subject line lengths vary depending on a host of factors including your industry, your target audience and, not surprisingly, the type of information you are trying to convey.

Here’s where things get a little simpler...

Most mobile devices are only able to display between 20 and 30 characters in their subject line.

If mCommerce is your target, or if you know that the majority of your clients are likely to read your email on the move, then these are the limits you should try to work to.

How to make the most of your

30 characters

The truth is, this depends on how your recipient reacts to your message. For those who don’t open your email (and there will often be more people who don’t than who do), they will still have glanced at your subject line, albeit momentarily, before deciding to ignore it.

Think of it as an exercise in brand awareness; they might not want to hear from you today, but it doesn’t hurt to remind them of who you are and what you stand for. Meanwhile, for those who are hesitating, the purpose of your subject line is to persuade them to read on.

Understand the purpose of a subject lineA subject line is a sales pitch, but what is it selling? Your company? Your exclusive offer? The email itself?

Example: You are sending out your company’s newsletter. You write in your subject line: ‘[Company name’s] newsletter for May.’ Or ‘Latest news from [Company name]’. WRONG. Your recipients probably receive hundreds of newsletters each year; why would they want to open yours? Think about the elements of your newsletter that your customers are most likely to want to read, and sell your email accordingly. For instance: ‘Our top five design tips for 2014’.

The length of time it takes for a recipient to decide whether or not to open your email.

Three seconds:

In other words, decide what you want to say, break it down in order of significance, tailor your choices to your recipient’s preferences and be sure only to convey the most important elements of your message.

Clear communicationWhen it comes to writing a killer subject line with such a restricted character count, it is often best to brainstorm the important elements of what you are trying to convey. Then, you can decide what to run with and what to ditch.
