1. Desire for value
Coupons are especially effective, seeing higher open, click and purchase rates than emails without. That’s why major retailers regularly refer to coupon codes offering specific percentages off. Standard retailers frequently offer savings that range from 5% to 20% off, though clothing retailers will typically offer an even wider range of 10% to 60%, depending on what point in the season they’re at. Subject lines that let people know how much they can save are effective in attracting attention and getting your customers to click through to purchase.
Understandably, though, that’s not suitable for all businesses and overusing them can make your communication seem overly salesy, even spammy. So don't rely too much on this approach unless you're the type of retailer that automatically factors 30-50% discounts into pricing like department stores and Gap brands do.
Even if you are not inclined to cut prices, you can appeal to value by describing to your products’ quality. So you don’t have to say “Our jeans cost less than theirs” but can say “You’ll wear our jeans twice as long as other ones; they’re that durable.” In more general terms, you can say that they don’t need to break their budget to look good, eat well, or have a good time.
2. FOMOFear of missing out. To achieve that, you have to work in a sense of urgency. Possible applications include emails from mutual funds warning you that the deadline for this year's IRA contribution is approaching or an eyeglass seller saying “This year’s flex spending account: use it or lose it.” It can also work in conjunction with the desire for value when promoting a particular bonus or sale offered for just that day, say “Order before midnight when your 25% off turns into pumpkin.”
3. Curiosity
The thrill of discovery that we sometimes experience stems from the wish we have to find the answer to the questions we have. Channeling that can be a powerful motivator for someone to open your email. This can be combined with FOMO or the incentive to save money with a “mystery offer” or that only reveals how much the customer will save after clicking through to the site. It can also work with a “mystery gift.” Even without a monetary incentive, you can work off curiosity with something like “See our 5 best-selling pieces” or “How to wear the color of the season.”
4. Appeal to laziness
People may not be proud of being lazy, but they do appreciate not having to exert themselves. Subject lines can target that when you refer to easy, one-click checkout, effortless outfit ideas, recipes that require just 4 ingredients, cleaning hacks, etc. that can even be used to market training for a particular skill like “Learn coding on your lunch breaks.”
5. Appeal to vanity
We’re all vain about something, and that’s not necessarily limited to our looks. If you know what your customers are proud of, you can appeal to that in your subject. For example, women who pride themselves on looking young may respond to “Warning: once you use this, you may get carded at the liquor store.” Fashionistas may respond to something like “exclusive styles for those who know fashion.” For pet owners, you can have a message like “You can always spot the best loved pets by seeing our logo on their collars.” In more general terms, you can always refer to an offer to your “VIP customers” to give their vanity a boost.
6. Humor
Even if you’re in a bad mood, seeing something funny can lighten it, even if it just coaxes a smile out of you, even more so if you laugh out loud. That’s the attraction of humor, and you can use it for email subject lines, drawing on the humor of breaking expectations. For example, an email seeking to market for Father’s Day shoppers can say, “Don’t get him another boring tie.” One aimed at graduates could say, “Remember how you complained about school? Prepare for something worse.”
7. Addressing pain points Drawing on what you know about your customer or contextual knowledge of what they would be experiencing or anticipating, you can use those in your subject lines. When marketers were sending out messages under lockdown, they had to consider what people would want under those circumstances to be comfortable and avoid boredom at home.
There are many seasonal opportunities to address pain points. For example, when a heatwave is in the forecast, your subject line can be “Keep your cool in these shorts.” or “All you need is air-conditioning and this ___” for drinks, warm weather clothes and accessories, or a summer line of beauty products. When cold weather hits, you can say, “Don’t go out in the cold; we deliver!”
Even when there is no particular occasion on the calendar, you can utilize empathy with a light touch by, say, emailing on a Monday with “Need a lift to carry you through the next 5 days? We have it here.” Or in situations in which weekend plans have to be shifted, “Weekend fun starts here.”
