If you don't capture your audience's attention in the subject line, they'll just hit delete without even opening the email. So choose a subject line that offers them a compelling reason to click. Here are seven types of appeals that can be very effective.
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. FOMO
3. Curiosity
4. Appeal to laziness
5. Appeal to vanity
7. Addressing pain points
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.”
