According to Omeda, the average open rate for subject lines with 20 characters or less is 29.9%. From there, performance drops significantly.

An email subject line generator helps sharpen your ability to convey a compelling message in fewer words.

Integrates Keywords

An email subject line generator provides suggestions with relevant keywords, which leads to better email searchability. You can also input your necessary keyword in before you generate subject lines, so they are crafted to meet your needs.

Tips To Writing The Best Email Subject Lines

Grab Attention Using Outlandish Words

Outlandish, quirky, and unique words have the power to make your email subject lines stand out in an overloaded inbox. Think about it. Would you rather open a newsletter that reads “June Newsletter” or “Sizzling June Insights Just For You!”?

Personalize The Email Subject Line

Readers are 26% more likely to open emails with personalized subject lines. A subject line like: “John, We’ve Curated These Special Offers Just for You!” adds a personal touch that makes the recipient feel seen and valued.

Start Subject Lines With Action Words

Starting your email subject lines with strong action verbs can inspire your readers to take action themselves. Instead of something like “Sales Report Attached”, use “Uncover Key Insights from Our Sales Report”. The word ‘Uncover’ not only suggests action but also that valuable information awaits the reader.

Keep Subject Lines Short

Sometimes, less is more. Keeping your subject lines short and concise can have a powerful impact. Consider something like “Save Big Today!” It’s straightforward, to the point, and packs a punch—all in just three words.

Match Your Brand’s Style

Your subject line is a reflection of your brand, so make sure it matches your brand’s style and tone. For example, a formal and professional law firm could use a subject line like, “Important Updates on Tax Laws”. If your brand is more casual or playful, like a children’s toy company, you could use a subject line like “Get Ready for Adventure with Our New Explorer Set!”

Indicate Required Action

If you want your readers to do something, let them know clearly. A subject line like “RSVP Today for Our Exclusive Webinar” leaves no room for guesswork. It indicates exactly what action you want your readers to take, increasing the chances that they’ll do exactly that.

Create Urgency and Scarcity

Incorporating a sense of urgency or scarcity in your subject lines can prompt readers to act quickly. For instance, a subject line like “Hurry! Only a Few Seats Left for Our Masterclass” can trigger the fear of missing out and encourage immediate action.

Highlight Exclusive Offers or Benefits

Including exclusive offers or benefits in your email subject lines can entice recipients to open your emails. Whether it’s a special discount, early access to new products, or insider information, emphasizing the exclusivity of what’s inside can increase the perceived value of your emails and motivate recipients to engage with them. For example, “Exclusive VIP Access: Limited-Time Offer Inside!”

Limit Your Punctuation

Studies indicate that limiting subject lines to three punctuation marks is optimal. Excessive punctuation can give emails a spam-like appearance, particularly with numerous special characters.
