Five tactics for email subject lines that hit 90% open rates: keep them to 2-5 words, write a one-sentence preview that teases like a movie trailer, use emojis sparingly, apply title case to the subject line, and use open-loop curiosity to pull readers in.
5 ways to make your customers click your emails so hard they crack the screen. Subject line should be 2 to 5 words. Preview text, just one sentence that builds on the subject line without giving away too much, like a really good movie trailer that teases. Use emojis sparingly. One well-placed emoji can add a ton of visual appeal. Do not overdo it. Too many emojis are gonna make your emails look unprofessional. Capitalize intelligently. Use title case for all of your subject lines to give them that more professional enhanced look. Make sure that your preview text is just normal, regular capitalization. This can actually really change how your emails are perceived. Open loops. Make your audience curious so that they feel compelled enough to open your email to actually close that loop. Using this psychological trick to your advantage can literally make you millions of dollars.
