How to write the best flash sale email subject lines

The subject line is the first thing a recipient sees when they receive an email. Whether they open the email or not really depends on whether a subject line catches their attention.

The best flash sale subject lines have the following features:

1. A sense of urgency

People can be averse to missing out on good deals. You can highlight the time-limited nature of the sale to create a sense of urgency and encourage them to open the email and take advantage of the offer before it’s gone.

You can create a sense of urgency using words and phrases like:

• Sale starts (soon/today/now)
• Limited time offer
• Don’t miss this
• Now
• Fast
• Save today
• Act now

In fact, Omnisend’s post-Black Friday research showed that “Sale starts…” and “Last chance” had the highest effect on open rates.

2. The value proposition 

A flash sale email subject line should convey the value or benefit recipients will gain by opening your email. 

Whether it’s a significant discount, exclusive products, or early access, your subject line should let the reader know what’s in it for them. 

Emphasizing the value proposition can grab recipients’ attention and make them curious to learn more by opening the email.

3. Emojis

Emojis can add a visual element that breaks the monotony of text and stands out.

They can convey emotions, emphasize urgency (⏰), highlight offers (💸), or add a playful tone.

You can use emojis in your flash sales email subject lines to grab attention and add a touch of personality.

Pro tip: Use emojis to emphasize something in a positive context.

4. Flash sale details

Providing some details about the flash sale can encourage interested customers to open your email.

Specific details about the flash sale, such as the discount percentage, duration, or unique selling points should be included to generate interest.

Pro tip: Don’t give recipients too much information. Provide limited (but adequate) information that generates curiosity to open an email and find out more.

5. Pique curiosity

Get your subscribers curious about the content in your email by providing open-ended details in your flash sale subject lines.

Tease them with a question or promise something interesting that compels them to read the email.

Make it funny. Flash sale subject lines that make subscribers laugh make them curious to see what’s inside.

You could also say something unusual, such as a cliffhanger that tempts readers to open the email.

How to create the best flash sale email

Flash sales are a great way to clear out inventory but you need to take care of several aspects to drive sales conversions. 

Let’s take a look at the key components to focus on for crafting the perfect flash sales email that drives customers to take action:

• Subject line: Keep it concise, typically under 50 characters. Include important information about the email, like the flash sale offer, the product, or the timeframe
• Headline: You can use a bold headline to announce the offer and encourage further reading
• Email design: Visual appeal can enhance readability and engagement — use eye-catching design elements, such as high-quality images, bold colors, and clear typography, and keep the layout clean and easy to read across various devices
• Email copy: Provide more details about the flash sale, such as which products or services are included and any limitations in time frame, quantity, or location

• Terms and conditions: Provide clear terms and conditions for any offers to manage customer expectations

Best practices for flash sale emails

Here are some best practices you can follow to ensure that your flash sale emails engage recipients and drive sales.

Timing and frequency

Don’t wait until the last minute. Instead, announce your flash sales a few days in advance to create excitement.

Consider sending your main sale email during peak open times, which often fall mid-week (Tuesday, Wednesday, Thursday) in the afternoon.

Flash sales thrive on a sense of urgency. Avoid running frequent flash sales to customers to ensure it holds more value when you do. Aim for a strategic cadence, perhaps monthly or quarterly, to maintain the “limited-time offer” appeal.

Segmentation and personalization

Targeting different customer segments with different messaging can enhance relevance and engagement.

You can segment your email list based on demographics, purchase history, and interests. Then, you can tailor your flash sale message to suit specific customer segments.

Customize the flash sales email subject lines, product recommendations, and offers for each segment to boost open rates and conversions.

Follow-up reminder

You can send a reminder email shortly before the flash sale ends to encourage last-minute purchases. Include a countdown timer to give a visual cue of the limited time remaining.

A/B testing

Using A/B testing for your flash sale campaigns can allow you to optimize the various elements, such as subject line and offer, for maximum impact.

Consider experimenting with different subject lines, email layouts, and offers to see what works best with your audience. 

Next steps

You already put a lot of effort into organizing your flash sales. Don’t allow ineffective flash sale email subject lines to make them a flop.

By following the tips and best practices outlined in this post, you can create high-performing flash sale email campaigns that capture attention and boost sales. 

Put these tips into action and take advantage of the power of flash sales in your email marketing strategy.
