Personalization increases the likelihood of your email being opened by 26%. Why? Your readers want to feel like you care about them individually. You can utilize merge tags in your email subject line to include the subscribers first name, or include their past purchase history.
Take this example from Panera. Not only is this subject line utilizing the subscriber’s name, but it’s also offering them a way to save money with a rewards program.
If you’re looking for more engagement within your actual email, asking your readers a question in the subject line is a great way to receive action. These emails can ask your customer feedback which not only provides you valuable information but shows your customers that you care about their overall experience. You can also use questions to provide news or updates about your company. Questions will grab your reader’s attention and direct them back to your brand.
If you have an Alexa, this email is a great way to learn about any new updates. By asking a question in the subject line, it’s straight the point and offers a bit of mystery.
Solve problems with "How to"
Add value to your subscriber’s inbox by providing them the answers to their questions. ‘How to’ email subjects lines work because it’s setting up expectations about the email’s content, and hopefully, is a topic that’s important enough to your subscribers for them to click.
This example from Clean Plates illustrates how subscribers can live a more healthy lifestyle—which appeals to a wide variety of audiences.
Add a sense of urgency
Subscribers often have FOMO—fear of missing out—on a deal that’s not going to be around forever. Creating a sense of urgency in your subject line helps entice the reader to open your message because they won’t want to miss out on what you’re offering.
Thrive Market utilizes buzzwords ‘last’, ‘final’, and ‘mega savings’ to really drive home the fact that a sale is happening and it’s ending soon. With these words, subscribers are most likely to click on the email to discover what deals they could be missing out on.
Optimize with character counts
With shorter user attention spans, even your character count can make a difference in your open rates. Seven words seems to be the sweet spot.
Emojis are a great way to have a little fun with your subject line and grab your subscriber’s attention with a creative flair. Choose a relevant emoji that relates to your content, but ensure you test it carefully across different operating systems. For example, emoji’s do not appear the same on iPhones and Androids.
The double palm trees in this email from Joss & Main draw a reader’s attention immediately to the subject line. It’s creative, eye-catching, and on theme with an outdoor seating sale.
