Independence Day: The Email Subject Lines that Do and Don’t Work

X

Fourth of July is perhaps the most important holiday in the U.S., so many brands might think they can leverage the pride, awe and other emotions associated with this holiday to craft email campaigns that drive sales. Our research reveals, however, that emotionally charged email subject lines don’t necessarily lead to fireworks for consumers, so to speak.

Regardless, the holiday remains a great reason to reach out to consumers via email, but brands should do so carefully.

To help marketers curate the most effective subject lines and write content with the right voice for their Fourth of July-themed emails, Yesmail, in partnership with Persado, analyzed over 17,500 unique subject lines from emails sent 15 days before the Fourth of July from 2013, 2014 and 2015.

Findings

With the number of holiday-themed campaigns increasing year-over-year, the right subject lines can help brands stand out from the noise and encourage subscribers to open. From Mother’s Day to peak marketing events like Black Friday and Christmas, a subject line with the right tone, keyword positioning, and emotional language can be just the trick brands need to turn an unsuccessful email campaign into one with ample return on investment.

Growth of Themed Subject Lines

The data demonstrates that the number of Independence Day-themed subject lines that marketers sent grew by 36 percent from 2013 to 2014 and by 12 percent from 2014 to 2015. This is despite the fact that open rates for themed campaigns were lower than for non-themed ones over the same period.

What’s more, themed emails during Independence Day do not always hit the mark. Over the past three years, non- themed emails had an average open rate of 10.6 percent while the open rate for Fourth of July-themed emails averaged 9.3 percent, a 13.8 percent difference. The most likely reason for this significant differential is that Independence Day is not a major shopping holiday. Beyond fireworks and barbecue supplies, consumers do not have much of a shopping list so subscribers may not be relying on email for sales information and deals.

Keyword Positioning

The position of the keywords in a holiday-themed email subject line (in this case, ‘Fourth of July’ or ‘Independence Day’) can significantly influence the success of the campaign. According to our data, using a phrase related to Fourth of July at the beginning of a subject line is more effective than incorporating it later on in the subject line. The former strategy earned an open rate of 9.5 percent on average, while the latter earned an open rate of 8.6 percent on average.

Emotional Language

Beyond themed-campaigns and mention of a keyword itself, emotional language in a subject line can impact open rates. Brands have many emotions to choose from such as encouragement, fascination and urgency. Making the right choice can boost a campaign’s open rate.

In 2013, 2014 and 2015, half of Fourth of July email subject lines conveyed at least one emotion. Of those emails, subject lines that did not convey emotions had a higher open rate (9.57 percent) than those that did (9.25 percent). Despite this trend, certain emotional language used in Fourth of July-themed emails fared better than the rest. 

Top 3 Emotions by Year

Emotional language that communicated Encouragement and Exclusivity through a subject line generated the highest open rates among emotive Fourth of July-themed emails from 2013 - 2015. 

Top 3 in 2013:

  3. Fascination
    e.g. “Our favorite 4th of July essential is...”

Based on our data, marketers were able to learn from poor-performing emotional language year-to-year. However, underperforming emotional language like excitement did persist from 2013-2014, and urgency from 2014-2105, for Fourth of July-themed emails.

  2. Urgency
  3. Celebration
    e.g. “Celebrate the 4th of July in Style with American Flag Swimwear!”

Implications

While we often find that brands can better engage customers by eliciting emotion through their email subject lines, the Fourth of July has been a useful reminder that marketers must identify the right context and consider the unique undertone of every holiday.

Marketers should not necessarily shy away from emotional language when creating Fourth of July-themed subject lines, but rather must be very particular about the emotions they choose to incorporate, especially considering that the top performing-emotional language for the Fourth of July had more overlap year-over-year than the bottom-performing emotional language.

Likewise, this Independence Day, marketers should be intentional about introducing the holiday into the beginning of the subject line rather than at the middle or end. This subject line structure will help brands increase open rates and engage subscribers during the Fourth of July holiday.
