The challenge with Valentine’s Day promotions is to create subject lines that are compelling enough to drive action without being overly aggressive. The right balance can significantly boost your campaign’s success.

Follow these tips to get better results: 

  1. Focus on value, not just the sale: Highlight the benefit or value of your offer, not just the discount.
  2. Create a sense of urgency: Use time-sensitive language to encourage quick action, but avoid sounding desperate.
  3. Be clear and direct: Let your subscribers know exactly what to expect but keep it concise.
  4. Personalize when possible: Personalizing the email and the subject line to the recipient can increase open rates.
  5. Use engaging language: Instead of the standard “sale” language, try more engaging phrases that spark curiosity.

General Subject Lines for All Companies

You can use ideas like the ones below, regardless of your business type.

Use words that hint at sales or lower prices, such as discounts, savings, or specials. 

  • Cupid’s Arrow Points to Savings!
  • Show Love: Shop Our Valentine’s Selection!
  • Love is in the Air… and So Are Discounts!
  • Valentine’s Day Treat: Buy One, Get One Half Off!
  • Valentine’s Day Exclusive: Save on Romantic Gifts!
  • Hurry! Valentine’s Day Offers End Soon!

Come up with Unexpected Angles

Integrating unexpected angles in your Valentine’s Day email subject lines can make your messages more noticeable. This approach involves presenting unconventional ideas or perspectives to spark interest. 

Valentine’s is associated with romantic love, chocolates, and roses. So, if you turn these ideas on their head, you can create something refreshingly original. This strategy works because it disrupts the expected narrative and captures attention through surprise. 

For example, you could focus on celebrating self-love and independence instead of romantic relationships like this: “This Valentine’s, It’s All About You: Celebrate Yourself.” 

Another option is to shift the spotlight to other types of love, such as platonic. In this case, a subject line like “Who Needs Cupid? Celebrate Friendship This Valentine’s!” could work nicely.

How To Make Your Valentine’s Subject Lines Stand Out

Distinctive subject lines have a higher chance of catching the reader’s eye and compelling them to open the email. 

During Valentine’s Day, when typical phrases and offers are overused, a subject line that breaks the mold could boost your open rates. It also differentiates your message and reflects your brand’s creativity. 


Ask Questions

Questions demand mental engagement — when someone reads a question, they instinctively start thinking of an answer. This psychological trigger can increase the likelihood that the recipient will open your email because the recipient wants to find the answer or learn more inside the email.

Here are some examples of question-based subject lines for Valentine’s Day:

  • Looking for the Perfect Valentine’s Gift?
  • How Will You Say ‘I Love You’ This Year?
  • Who’s Your Valentine’s Day Hero?
  • What’s the Secret to a Perfect Valentine’s Date?
  • Want to Make Valentine’s Day Unforgettable?
  • Need Last-Minute Valentine’s Ideas?

Use Emojis

Emojis add personality, emotion, and visual appeal to your subject lines. They convey emotions and ideas instantly and make your message more relatable. They also lend a modern and friendly tone to your communication, which is ideal for a holiday that celebrates emotions and personal connections.

Here are some emojis appropriate for Valentine’s Day subject lines:

  1. ❤️ – Heart
  2. 😍 – Heart eyes
  3. 💕 – Two hearts
  4. 🌹 – Rose
  5. 💌 – Love letter
  6. 💝 – Heart with ribbon
  7. 🥰 – Smiling face with hearts
  8. 💘 – Heart with arrow
  9. 🍫 – Chocolate bar
  10. 🥂 – Clinking glasses
  11. 🎁 – Gift
  12. 🎈 – Balloon

Use Numbers

Numbers stand out visually. So, they make your subject lines more noticeable. They also offer a sense of specificity and clarity that can be compelling for recipients. 

Finally, numbers help make your subject line more digestible, which can mean the difference between opening or ignoring your email. 

You can use numbers to highlight discounts, create a sense of urgency, or add relevance.

Other Techniques to Differentiate Your Subject Lines

With some creativity and a keen understanding of what captures your audience’s attention, you can find plenty of effective ways to make your subject lines different.

Here are a few more ideas: 

  1. Humor: A light-hearted, humorous subject line can be a breath of fresh air amidst more serious content. For example, “Love is in the air – Don’t Forget Your Mask” 
  2. Storytelling: Weave a short, intriguing narrative in your subject line to capture the reader’s curiosity. For example, “When Cupid Met Our Collection” 
  3. Personalization: Use customer data to personalize subject lines and make each email feel individually tailored. For example, “John, We Found Your Perfect Valentine’s Match”

Power Words for Your Valentine’s Day Email Subject Lines

Power words are impactful and emotionally-charged words that trigger a psychological or emotional response. They’re persuasive and can significantly increase the effectiveness of your subject line. 

For Valentine’s Day, these words can tap into the themes of love, desire, excitement, and exclusivity. Using these words is one way to make your emails stand out. 

How to Find and Choose Power Words

Follow these steps to find and use the right power words in your subject lines: 

  1. Identify the purpose: Start by determining the main goal of your email. Is it to inform, persuade, invite, or announce something special for Valentine’s Day?
  2. Use a thesaurus: A thesaurus is a great tool for finding synonyms that might be more impactful. Look up common words related to love and Valentine’s Day and note their synonyms.
  3. Analyze trends: BuzzSumo, Google Trends, and social media hashtags are useful for analyzing popular content and the words used in your industry.
  4. Relevance is key: Choose words that align with the core message of your email and your brand’s tone.
  5. Integrate power words: Seamlessly incorporate your chosen power words into the subject line. Make sure they feel natural and not forced.

Understanding Your Audience: The Key to Email Engagement

No matter how catchy your subject line is, without the right email marketing practices, you can’t expect results. That’s why we recommend balancing your focus on words and your audience. 


Segment Your Email List for Targeted Messaging

Email segmentation is the process of dividing your email list into smaller, more focused groups based on specific criteria. These criteria can include demographics, purchasing behavior, engagement history, and even personal interests. 

When you categorize your audience into distinct segments, you can send more targeted messages to each group. 

Segmented campaigns often see higher open rates, click-through rates, and ROI compared to one-size-fits-all campaigns. Well-segmented lists also improve deliverability because they establish a track record of positive engagements and reduce spam complaints

Let’s check out a few examples of how to tailor subject lines to various audience segments: 

Audience SegmentSubject LineStrategy
Engaged or newly marriedFirst Valentine’s as Mr & Mrs: Make it unforgettableFocus on celebrating their new journey together and offer romantic and memorable experiences.
Long-distance relationshipsLove knows no distance: celebrate Valentine’s Day together, apartFocus on virtual dates or gifts that bridge the distance and acknowledge their unique situation.
Repeat customersA Valentine’s thank you: exclusive early access just for youAcknowledge their loyalty with exclusive offers or early access to special collections.
First-time buyersLoved your first purchase? Here’s a Valentine’s treat for your nextEncourage repeat purchases with special deals or discounts on their next buy.
Younger audienceValentine’s day on a budget: trendy gifts under $20Focus on trendy, affordable gifts appealing to younger customers’ preferences and budgets.
Older audienceElegant Valentine’s Day: Timeless gifts for your loved oneOffer classic and sophisticated gift options that resonate with an older demographic.

Use Audience Data to Personalize Your Content

Effective email marketing, especially for emotionally charged occasions like Valentine’s Day, goes far beyond addressing recipients by their names. Your content should make each recipient feel like the email speaks directly to them. 

How can you achieve this? 

By collecting and analyzing customer data. Correlate past purchase history and engagement with previous emails to see which content resonates with which audience. Use this information to segment your audience based on their behavior and preferences.

We also recommend encouraging customers to provide information about their preferences, interests, and lifestyle through surveys or feedback forms.

Then, you can use this data to personalize your content. Incorporate dynamic content in your emails that automatically adjusts based on the recipient’s profile. For example, showing gift suggestions based on their recent views or purchases.
