Subject line recommendations
One of the most valuable parts of your email campaign is your subject line. A great subject line will entice your audience to open your email, giving you a better chance of increasing engagement and ROI from your campaign.
When creating your subject line, a blue light bulb icon will appear with our new subject line recommendations, which will help you craft the perfect subject to maximize open rates:
- Limit subject line length to 60 characters – Long subject lines may get cut off when viewed on some mobile devices and email clients. We recommend using a maximum of 9 words and 60 characters.
- Avoid all caps – Your email performance may be negatively impacted if your subject line reads as though you’re yelling. Using caps can be effective if you capitalize just a single word to highlight its importance.
- Use emojis carefully – Emojis are fun and can add personality. However, according to our research, you should use no more than 1 emoji at a time to avoid looking like spam. Use an emoji to supplement words rather than replace them.
- Limit punctuation – Our research shows that it’s best to use a maximum of 3 punctuation marks (in this case exclamation or question marks) per subject line. Too many can make your email look like spam.
With these recommendations, you can feel confident that your subject line is the right length, contains the right punctuation, and has just the right amount of emojis 🤩
