Easier said than done- especially during the holidays when all businesses send emails and our inboxes are overwhelmed with hundreds of messages.

From this article, you will learn how to craft that “effective and actionable” subject line as well as what subject lines performed best during the holidays last year.

We have analyzed the most common words, discounts, and emojis that contributed to the best open rates. Carry on reading and learn from the best ones.

1. Insights Into Holiday Email Subject Lines From 2018

We analyzed over 6000 campaigns sent to clients bases with more than 6000 subscribers between Nov 27, 2018, and Jan 5, 2019. This time period was chosen on purpose to cover the entire holiday season that started just after the Black Friday/Cyber Monday weekend.

For the best Black Friday/Cyber Monday subject lines, carry on reading here.

What we found in campaigns coming after Black Friday/Cyber Monday stood well apart from the shopping weekend.

First of all, merchants sent multiple campaigns. During the six weeks that we were analyzing, merchants sent significantly more emails than usually do. Some of them were sending campaigns related to dates and occasions, but the vast majority of senders did that randomly.

The most popular words in those subject lines were the following:

It was quite surprising that during this time only 3.75% of subject lines had “holidays” mentioned in the subject lines. “Christmas” was way more popular.

As you can see the most popular word was “OFF”, which indicated discounts. Overall, 27% of all subject lines had a discount mentioned. It means that even the biggest sales of the year were over, merchants carried on offering deals and discounts for their customers.

The most popular discounts during this period were 25% and 30%. See the list of the most popular discounts that were offered by merchants during the 2018 holiday season:

25% and 30% discounts were the most popular. Exceedingly few merchants offered generous 50% discounts. On the other hand, a 10% discount was seldom as well.

What was interesting that discounts with “$” signs were used less than 20 times in all 6000 campaigns.

2. Top Five Emojis In Holiday Email Subject Lines

Emojis are getting more and more popular in email subject lines. Last year 18% of holiday email subject lines had one or more emojis inside. Emojis add that little punch of color and fun to draw your customer’s eye and make your email stand out from the crowd.

If emojis fit your brand identity, consider using them in your subject lines as well. Here is why:

1. Emojis help you stand out in a crowded inbox
2. Emojis increase your open rate
3. These little icons save space in the subject line
4. They help convey an emotion
5. A/B testing with and without emojis won’t cost you a thing.

During the holiday season last year, some particular emojis stood out from the rest. Obviously, the ones most related to the holiday season:

4. The Five Main Principles To Crafting Your Holiday Email Subject Line

You can only learn what subject lines work best for your business by testing different variations.

However, some best practices can facilitate your initial ideas for subject lines. By following them you will increase your chance to be noticed and get emails opened. Also, you will reduce the chance of ending up in the SPAM folder, which is critical to any email campaign.

So let’s see what good subject line practices are:

#1 Concise subject lines

As you can see from the email subject lines listed above, you don’t need fancy words in your subject lines. Try to be short and straight to the point.

Subject lines should be visible for both – mobile and desktop – users, so the sweet spot is 5-7 words or 45-55 characters.

Subject lines of this length are optimal for all gadgets that people use for reading emails.

#2 Key information goes first

Long email subject lines are always at risk of being cut off on mobile devices. To avoid this, focus on your key proposal and put it in front.

If this time you have a sale, start your email subject line with “Sale”. If it’s for Black Friday or New arrivals, put that in the front.

#3 Urgency and FOMO matter

If people leave something “for later”, it often means “never”. That’s just how we are.

That’s why you should create urgency and push your customers to act now and don’t postpone it for later.

You can create that by using limited-time offers: “24-hours offer”, “Only today”, “Sale ends tonight”, etc.

Another good practice is including FOMO (fear of missing out) elements, like “Don’t miss”, “Have you already seen…”, etc.

#4 Use actionable verbs

All marketers know: strong and measured call-to-action is king in online business. Use this rule in your email subject lines. Short and punchy words like “get”, “buy”, “discover”, “learn” encourage people to click on and take action.

However, don’t overdose them because they might trigger spam filters.

I wouldn’t suggest using them together with spammy words like “free”, “100%”, or in spammy combinations with letter capitalization, exclamation marks, etc.

#5 Include numbers

50% of top holiday subject lines listed above include numbers. As you can see, merchants use them a lot.

There are a few reasons why numbers are useful in the email subject lines:

1. They stand out from the text
2. They provide specific information about a sale or discount and set up customer expectations

Numbers are definitely something worth trying for upcoming holiday email campaigns.
