On Valentine’s Day, people worldwide open their hearts and wallets to mark this special date. 

According to a report, Valentine’s Day individual spending will go up from $175 in 2022 to an estimated $192 in 2024, meaning more sales opportunities for you as an eCommerce and online retailer. 

Email is the communication channel of choice for most businesses. However, with the volume of promotional emails flooding inboxes during this period, you’ve got to put your creative ink to work, crafting relevant Valentine’s Day email subject lines that stand out.

This way, you increase email open rates and stand a chance to get your share in the Valentine’s sales gold mine. 

Crafting Valentine’s Day email subject lines that stand out isn’t rocket science, nor should it be a shadow box. This post covers tips for creating engaging and romantic Valentine’s Day email subject lines, examples from big brands, and more.

Ready? Let’s begin.


Subject Lines: A Deal Breaker in Email Marketing or Not?

You’ve heard it repeatedly – “Don’t judge a book by its cover.” Well, in email marketing, the reverse is the case. Here’s why. 

Promotional email examples with concise subject lines

The image above is a typical representation of individual inboxes—crowded and filled with promotional, transactional, and other types of emails from competing brands.

The easiest way to get lost in this ocean of emails is to use a bland subject line that evokes no emotion or curiosity. It is worth noting that 47% of email subscribers based their decision to open emails on the subject line alone, and nearly 7-in-10 marked emails as spam based on subject lines as well. 

So, in a sea of messages vying for attention, your subject line is your audience’s first contact with your email content. Crafting creative and compelling email subject lines could determine if your email is being opened, examined, or lost in the mix. 

As marketers, we recognize that timing is everything, and Valentine’s Day isn’t an exception. This day of love usually provokes a surge in consumer spending, making it a strategic opportunity to leverage.

Now, the following are some reasons why crafting effective subject lines is crucial for email marketing.

First impression matters

The subject line is the first thing recipients see in their inbox. Engaging subject lines can create a captivating first impression, encouraging customers to open the email. According to research conducted by Litmus, 34% of people decide whether to open an email based on the subject line alone.

Boosting open rates

Engaging subject lines can significantly influence higher open rates. Adestra, an email marketing automation software, reports that personalized subject lines increase open rates by 26%.

Tailoring your subject lines to a Valentine’s Day theme can tap into the emotional connection of the season, prompting more users to open your emails.

Standing out from the inbox crowd

During Valentine’s Day, inboxes are usually flooded with promotional emails like we established earlier. Your subject line needs to stand out from the crowd.

With 69% of email recipients reporting email as junk mail based entirely on the subject line, crafting a unique and relevant subject line ensures your message is noticed in the crowd and not marked as spam.

We’ve been able to shed light on the critical role subject lines play in email marketing, especially during seasons of celebration like Valentine’s Day. Now, let’s delve into practical strategies for crafting compelling Valentine’s Day email subject lines to captivate your audience and drive engagement.

Best Practices to Create Valentine’s Day Email Subject Lines that Stand Out

Crafting compelling subject lines in your Valentine’s Day email campaigns requires a critical balance of creativity and relevance. To ensure your messages stand out in crowded inboxes and drive engagement, here are some recommendations:

1. Embrace emojis and wordplay

Incorporate emojis, puns, and wordplay into your email subject line. An example is:

“Love at first bite: Sweet deals for your sweetheart❤️” 

This subject line provides a playful twist while conveying the Valentine’s Day theme and exclusive Valentine’s offer. Remember that emojis add a touch of emotion and ease the intensity of plain text, capturing the needed attention in a pool of emails.

To know more, read our blog on the best ways to include emojis in your email subject lines.

2. Personalize the experience

Use dynamic tags to insert the recipient’s name or location, creating a personalized mail experience and a sense of individuality for each recipient. 

Beyond inserting subscribers’ names in the subject lines, another excellent way to personalize the experience is by crafting different subject lines for specific email list segments. This significantly boosts engagement rates as different subscribers get emails that resonate personally with them based on where they are in their customer journey

EngageBay lets you personalize all aspects of your email—subject lines, preview text, and email content.

All you need to do is go to the marketing dashboard, choose Create new broadcasts or sequences, click on Personalization, and see a drop-down menu with various personalized fields and tada! You’re all set to click send.

3. Provoke curiosity

In the spirit of keeping it real, you’ll agree: whenever you see an email with a subject line that provokes curiosity in your inbox, you wear your investigation hat and don’t get it off until you see what the email is about, right? So, it makes sense to create subject lines that incite your recipients’ interest and make them eager to open the mail to find out more. 

Here’s a subject line you can steal:

“Sarah, knock me off with this Valentine’s secret 💝.”

This subject line works for two main reasons. One, you are wondering why you have to knock off whoever the sender is and why they even want to be knocked out in the first place. Second, you’ll want to discover what this invisible knockoff punch is all about.

4. The shorter, the better

The phrase ‘less is more’ is double true regarding subject lines. A report from Invesp shows that email open rates and subject line word count don’t see eye-to-eye. In simple terms, the more words you have in your subject line, the lower the open rate.

The exception is subject lines with less than five words (even though they still do significantly better than subject lines with longer words). So, it’s best to keep subject lines between 6 and 10 words for maximum results.

With the limited spaces available for email subject lines, conveying your message concisely is essential while still capturing attention. Here’s something to steal:

“Sweet deals inside: Goes away at midnight 🎁.”

This subject line is eight words long (within the ideal length) and offers a sense of urgency.

Applying these tips is a step toward creating Valentine’s Day email subject lines that stand out. 

Now, let us consider some real-world examples (from my inbox) by brands that have successfully captured recipients’ hearts and driven engagement with their subject lines.

This email shows that irrespective of your business or what you sell, you can always customize your Valentine’s Day offer to make sales. Second, it’s personalized with my name. Aside from this, it is concise (8 words) and evokes the feeling of self-love.

2. Spread the love with a Valentine’s Card

Dos and Don’ts for Valentine’s Day Subject Lines

We compiled some dos and don’ts to keep you on track in creating your Valentine’s Day email subject line. 


1. Always conduct A/B testing on your subject lines

Optimize your Valentine’s Day email campaign by conducting A/B testing on different subject lines. Analyze the overall performance of every subject line to understand what resonates well with your audience. This process helps refine your subject line for better results.

Steps to implementing A/B testing on your subject lines

Here are key steps to getting started:

Segment your list

Start by segmenting your email list into two or more groups. This allows you to test different subject lines and their impact on important metrics like open rate, click-through rates, and conversion rates.

Test the variables

It is vital to note that crafting Valentine’s Day email subject lines doesn’t require much to make significant differences. Hence, the golden rule is testing one variable at a time.

Experiment with different factors like word combinations, emojis, personalization elements, and subject line lengths.


  • Test 1: Subject line with emoji vs subject line without emoji
  • Test 2: Short and sweet subject line vs a longer and well-detailed subject line

This strategic approach provides data-driven insights into what works for your target audience.

Interpret the results

Once you have completed your A/B Testing, it is time to decode the results. Note that you must focus on critical metrics like open rates. With careful observation, you select the subject line that outperforms the other.

For instance, if the subject line with emojis outperforms the others, consider incorporating emojis in future Valentine’s Day email subject lines.

Also, it is vital to consider subtle differences beyond the primary metrics; for instance, does a subject line cause more click-through rates or a better conversion rate? Understanding the holistic impact ensures a complete optimization strategy.

Continue to refine what works

A/B Testing, or split testing, is an invaluable tool to refine your email subject lines and boost overall campaign performance. Also, it is not a one-time affair. As your audience options evolve, so should your subject lines.

Regularly revisit and refresh your A/B Testing strategy to stay updated with your audience preference and secure the clicks.

2. Segment and personalize

In email marketing, where personal connection is essential, segmentation and personalization are your best tools to create emails that resonate with individual subscribers.

Segmenting your email list is like creating a unique experience for each subscriber. You can tailor your Valentine’s Day email subject lines to resonate with their categories by segmenting your subscribers based on demographics, purchase records, or open rates. 

For instance, if your business offers different Valentine’s packages and caters to a wide swath of people, sending emails with the same subject lines will be counterintuitive. In this instance, you can send an email with a subject line that says: “Blossoms of love for you forever love” for flower lovers while crafting something entirely different for the other segment.  

Using email marketing software with dynamic tags that let you insert recipients’ names, locations, and personalized discounts into the subject line is a must. 

Imagine receiving an email with a subject line that reads:

“John, unlock your exclusive 15% off Valentine’s Day treats.”

It does not only create attention but also establishes a connection with the recipient.

Studies have shown that personalized email subject lines yield a 26% higher open rate than generic ones, which shows the importance of personalized emails. When your subscribers feel your message is crafted specially for them, they’re likelier to open and engage your content.

Segmentation and personalization are not just buzzwords in email marketing; they are your secret ingredients to a successful Valentine’s Day marketing campaign. 

3. Connect with your recipients’ emotions

Connect with them deeper by tapping their emotions with love, affection, and romance. Craft subject lines that resonate with the sentimental nature of Valentine’s Day, inspiring great emotional responses from your recipients.

4. Create a feel of exclusivity

Make your subscribers feel special with unique offers. Phrases like “Exclusive Valentine’s Day Offer” or “Limited-time Only: Valentine’s Day Edition” can create an experience of urgency and make your recipients feel happy to get a unique offer.

5. Use action-oriented language

Encourage recipients to act immediately by incorporating compelling verbs into your subject lines. Words like “discover,” “unveil,” or “surprise” create a sense of excitement, inspiring engagement and thereby increasing open rates and click-throughs.

6. Put keywords to good use

Keywords are a good way to increase your brand’s visibility. There are several ways to implement this. For example, If your business caters to a particular geography, including it in your email subject line would make sense. 

So, instead of saying, “Dinner for two at the price of price one,” it would resonate better with people in a specific location if you say, for instance, “Miami sunset dinner for two: Promo code inside.” Now, it clicks for those in Miami that this offer is actually for them.

If your restaurant is a franchise with multiple locations, using a subject line like this requires segmenting your email list so each person gets an email personalized to their location.

In general, research relevant keywords related to Valentine’s season, love, and gifting and naturally integrate them into subject lines. While doing this, ensure your subject line is clear and concise. 

Now that we have considered the Do’s, let’s look at the Don’ts!


1. Too many emojis is a deal breaker

While emojis improve your subject lines’ appearance, striking a balance is vital. Avoid the usage of too many or irrelevant emojis, as this can be very unprofessional or may even look like junk mail. Choose emojis that complement the message without overwhelming the recipient.

2. Don’t lie to or mislead recipients

Maintain credibility by avoiding clickbait subject lines. Misleading your recipients will eventually hurt your brand and email reputation in the long run. Ensure your subject lines reflect the content of your emails to build and maintain credibility and long-term relationships with your audience.

3. Avoid generic terms while crafting email subject lines

During festive seasons, users’ inboxes are usually filled with buzzwords and generic offers like “Best Valentine’s Day offers” or “Don’t miss out–you’d want to avoid those. Craft precise, personalized subject lines that captivate your audience and distinguish your brand from competitors.

Now that we have explored the do’s and the don’ts, we’ll explore some vital elements of crafting Valentine’s Day subject lines that speak for themselves in your recipient inbox.
