Email marketing campaigns are among the most popular ways to reach prospects and customers. According to a report by Ipsos commissioned by Habeus, 67% of businesses employ email communications, a number which is expected to remain stable over the next five years.
In my own marketing writing business, I’ve seen a significant uptick in requests for content for email campaigns. Many of these campaigns are used for nurturing good leads who are not yet ready to buy. Other companies, realizing that the easiest sales are usually to existing customers, use email campaigns to remain top of mind with and upsell to customers.
Naturally, with this growing investment in email marketing and tight overall marketing dollars, marketing departments want to get the greatest bang for their buck with their email marketing campaigns. Indeed, when one of my clients, a large technology company in the Boston area first hired me, one of her questions was about my knowledge of email marketing content best practices. That got me thinking, what a great idea for a blog…
My next few posts will therefore present a series of best practices for improving the copy you create for emails used in email marketing campaigns.
My first posts in this series focus on THE most important content component of your email campaign: your subject line. Clearly, no one will see the rest of your message if your subject line is ineffective. According to a recent report by PinPoint, 8 out of 10 people will skim/read your email subject line while less than 2 in 10 will read the rest and take action. Moreoever, at least 40% of a reader’s decision to open or take action is based on the email subject and “From” line, while 69% of recipients decide whether to report email as spam based on the subject line.
This post and the next will discuss 10 best practices for subject lines.
1. Follow the 50/50 rule
When writing emails, many marketers save the subject line for last and devote minimal time to it. Big mistake. Because of the importance of subject lines, most experts recommend that you spend 50% of your time on the subject line and intro of your email, and 50% on everything else, including the design.
2. Set the right goals
Marketers often think that the purpose of subject lines is simply to get people to open your email. But if that’s all you want to do, your best bet would be to write a subject line that says something like “Increase Your Sex Appeal 1,000%.” Clearly that won’t do for most business emails.
Indeed, many years ago, an editor at PC Magazine put a picture of a sexy (clothed) woman on the cover of an issue about Laptop Computers with the express purpose of boosting newsstand sales—while he may have met that objective, he set off a firestorm of criticism and outrage. Was this worth the extra newsstand interest? Not really.
So clearly, the goal of a B2B email subject line isn’t just to get people to open the email.
Rather, you want to persuade readers to open the email and to take some appropriate action. For example, with B2B lead generation or nurturing email campaigns your immediate goal may be to get people to attend a webinar, download a whitepaper, listen to a podcast, go through a demo and so on. And your ultimate purpose is to take the customer to the next step in the buying process.
To meet those goals, your subject line needs to generate: Recognition, Interest, and Action.
· Recognition—When people receive an email that they don’t recognize, they are likely to ignore it, delete it, or report it as spam. Therefore, as a permission-based email marketer, your subject line has to inform people that the email comes from someone to whom they gave permission and is something they’re comfortable receiving.
· Interest—Here’s where your subject line has to get people to open the email.
· Action—The ultimate goal of your email is to get people to take an action, whether that’s a click, a download, a reply, a purchase….
3. Find the Right Length
Conventional wisdom has it that when it comes to subject line length, shorter is better, and that ideally subject lines should be no longer than 35-50 characters.
One reason for that rule of thumb is that email clients once limited the length of subject lines. If the subject line was longer, it would be cut off. Today, most email clients allow users to show up to 100 characters and to control how they view an email subject line when they configure their email. Thus, previous tight limits no longer apply.
Given that it is now possible to use longer subject lines, Alchemy Worx analyzed subject lines for more than 200 million emails. They found that the relationship between subject line length and results is not as simple as was previously thought.
The research found that:
· Subject lines of less than 60 characters are best for optimizing open rates.
· However, click-to-open rates (CTOR) are optimized with subject lines of over 70 characters. The CTOR rate is the ratio of unique clicks to unique opens. It is a measure of how effective your message is in motivating the recipient to click once they have opened the message. Thus, it is an indication of the relevance of your message.
Alchemy Worx theorizes that the reason for these results is that the most common way to maximize open rates is to use ambiguous or potentially misleading subject lines—a technique often used by spammers. Shorter subject lines are more likely to be ambiguous or misleading than longer ones.
Getting more people for whom the message is relevant to open the email requires a subject line that is specific and detailed, which usually requires more words or characters.
4. Decide What to Say
Mail Chimp analyzed more than 40 million emails looking for those with the highest and lowest open rates. It then pulled 20 from each pile and compared them side by side. The highest open rates ranged from 60% to 87% and the lowest performer s fell in the 1% to 14% range.
You can access MailChip’s list here.
Pinpoint performed a similar study. You can see examples here.
Mail Chimps conclusion: The best subject tell the reader what the email is about without being salesy or pushy. The worst ones read like headlines from advertisements.
Similarly, a recent survey of consumers by Return Path found that the most effective subject lines for catching attention were those that ”clearly state the offer.”
One interesting aside: Newsletters, which presumably are permission based vehicles that provide value for customers, are among the highest pulling types of emails in these lists.
5. Make it Interesting
Although subject lines must tell readers clearly what the email’s about, they don’t have to be boring—although I’ve seen many boring subject lines that have pulled amazingly well. Proven copywriting techniques commonly used by technology companies include the following:
· Emphasize benefits. This is among the most common type of subject lines for technology campaigns. It’s effective because it clearly explains to the reader “What’s In It for Me.”
· Tell readers “How to” “Best Practices” “X Steps to…”.These offer the promise of valuable information that can presumably help the reader do their job better, improve sales or reduce costs. Again, these subject lines are effective for their huge “what’s in it for me” factor.
· The news subject line. This works well if the customer has signed up for information about new products or services from your company.
· Subject lines that use urgency to create anxiety. In technology email campaigns, you’ll often see these in emails where the offer is a Webinar or teleseminar—which by nature is a limited time offer because the event takes place at a certain time. These subject lines are also very common in B2C communications. For example, both HP and Dell constantly send me limited time offers.
Mequoda Daily recently created a whitepaper called “The 13 Best Email Subject Lines” that talks about additional types of subject lines. When reviewing these subject lines, however, consider which are appropriate for B2B communications. Some subject lines that are perfectly acceptable for B2C communications sound spammy when used for B2B.
In my next post, you’ll find 5 more best practices regarding subject lines.
