How To Write High Open Rate Subject Lines

Draw Attention to Your Inbox
Make sure your key information stands out. Your email's subject line should be interesting enough to make someone want to read it all. Keep it short and use surprise, curiosity, or even emojis to grab attention.

Know Your Audience
If your email is for a specific city or group, make sure it goes to the right people. Use email segmentation to sort your audience into different lists. This way, you can send messages that matter to each group.

Sell Directly
Use a direct approach carefully. Sometimes a strong sell in the subject line is okay, especially if it’s about a specific product. It can encourage people to make a purchase.

Use Emojis
Emails with emojis in the subject line are opened more often. Try using emojis (without overdoing it) to increase engagement.

Announcements
Put the most important info in the subject line of announcement emails. Even if people don't open the email, they’ll still get the key details. They might come back to it later if they remember the subject line.

Write Like a Real Person
People like a personal touch in emails. Use a conversational tone to be friendly and approachable. Write like you’re talking to a friend to connect better with your audience.

Ask Questions
Ask a question in your subject line to get people interested. Questions can make people curious and more likely to open your email.

Avoid Spam Words
Stay away from words and punctuation that might make your email look like spam. Don’t use all caps, lots of exclamation points, or phrases like “Buy now” or “Free.” These can send your email to the spam folder.

Include a Deadline
Create urgency by including a deadline in your subject line. For promotions, send multiple emails: one to announce and others to remind about the deadline. This can motivate people to act quickly.

Show Value
Show value right in your subject line. Think about what your subscribers need and hint at a solution. This can make them curious and eager to open your email.

Use Humor
Make your subject lines funny to stand out. A joke or clever wordplay can make people smile and click open. Just make sure it fits your business vibe.
