Since we know that you have a lot on your plate as an SDR, we took it upon ourselves to discover how you can write better subject lines<\/a> for your cold emails.<\/p>\n\n\n\n We studied 2,344 unique subject lines from the thousands of cold email campaigns that comprised over 255,000 emails sent using Klenty<\/a>. Here, we\u2019ll share our study\u2019s findings and examples to inspire you to craft subject lines that boost your open rates.<\/p>\n\n\n\n We found that sales emails that had numbers in the subject lines had an average open rate of 20%. On the other hand, emails with subject lines didn\u2019t have an average open rate of 12%. <\/p>\n\n\n According to the Nielsen Norman Group, numbers catch the digital readers’ eyes. Why? Because we love data. Data points are usually represented in numerals. So, when people scan different subject lines in their inbox, a number is proven to get their attention.<\/p>\n\n\n\n Here are a few examples:<\/strong><\/p>\n\n\n\n Emails that included currency values in its subject lines had an average open rate of 29%, while the subject lines that didn\u2019t had 13% average open rate.<\/p>\n\n\n While having currency values in subject lines boosts open rates as per our study, you have to be careful as using a currency sign alone could potentially trigger spam filters. <\/p>\n\n\n\n Here are a few examples:<\/strong><\/p>\n\n\n\n As with including numbers, we found that emails with question marks in subject lines had an average open rate of 20%, while emails with subject lines without question marks had an open rate of 12%. <\/p>\n\n\n Questions immediately arouse curiosity in your prospects’ minds, prompting them to open your email. Remember that the question you ask in the subject line must be relevant to the prospect.\u00a0<\/p>\n\n\n\n Here are a few examples:<\/strong><\/p>\n\n\n\n Using emojis also had results similar to numbers and question marks. Those emails with emojis in subject lines had an average open rate of 20%, while emails with subject lines without emojis have an average open rate of 12%. <\/p>\n\n\n While using emojis in subject lines can indeed be attention-grabbing, use your discretion while deciding to use these as not all prospects might appreciate these little icons. A Nielsen Norman Group study says<\/a> that emojis in subject lines could potentially diminish your email\u2019s (and possibly your organization\u2019s) value in your prospect’s eyes. So, use an emoji only if you\u2019re sure it would truly add value to your subject line.<\/p>\n\n\n\n Here are a few emoji subject lines examples:<\/strong><\/p>\n\n\n\n Personalizing the subject line using the prospect\u2019s name is perhaps the most common<\/a> way of personalization as it is the easiest data to collect. And it is effective in boosting open rates<\/a> for a reason: People naturally become curious when they see their names in unexpected places, like a cold email that lands in their inbox, so they tend to open the email.<\/p>\n\n\n Our analysis found that by personalizing the subject line with the prospect\u2019s name, the average open rate goes up to 39%. On the other hand, emails that do not contain the prospect\u2019s name (but might still contain other kinds of personalization) have an open rate of just 10%.<\/p>\n\n\n\n Pro tip: <\/strong>Go beyond first-name personalization to see the best results. Consider other factors like your prospect\u2019s location, pain point, the tool they use, favorite ball game, etc., while crafting your subject line. <\/p>\n\n\n\n Here are a few examples:<\/strong><\/p>\n\n\n\n Here’s a surprising data point we found. * drum roll * <\/em><\/p>\n\n\n\n Emails with one-word subject lines have an open rate of 34.47%!<\/p>\n\n\n\n According to Marketo<\/a>, the optimum subject line length is 7 words. But, one-word subject lines can still be effective with prospects. Here\u2019s<\/a> an example of a firm reporting an increase in their website traffic by 83% by using a one-word subject line, which managed to garner an above-average clickthrough rate.<\/p>\n\n\n While a subject line with only one word can make the prospects curious, it runs the risk of triggering spam filters<\/a>. Coming up with a one-word subject line that could get your prospects to open your cold email but doesn\u2019t trigger any spam filters could be a fun challenge!<\/p>\n\n\n\n Here are a few one-word subject lines<\/strong> examples:<\/strong><\/p>\n\n\n\n The above findings will help you develop innovative approaches to subject lines and boost the open rates of your cold email campaigns. But, keep in mind that no trend in sales is set in stone and will work forever. So, take our data-backed findings and test them using A\/B testing<\/a> or other tools to see which of these works best for you.<\/p>\n","protected":false},"excerpt":{"rendered":" Have you wondered how many things should go in the right direction for your prospect to open a cold email?
