What Makes a Good Email Subject Line?

What makes a good email subject line?

As the number of emails we receive daily continues to increase, it's more important than ever to write email subject lines that entice recipients to open and respond. Here are seven tips on how to craft a winning email subject line:

1. Keep it brief.

Keep your subject line between 3-7 words, as shorter subject lines tend to perform better than longer ones.

2. Personalize it.

Add the recipient's name or company name to your subject line to make it more personal and grab their attention.

3. Make it interesting.

Use a catchy phrase or question that will spark the recipient's interest and encourage them to open your email.

4. Offer value.

Tell the recipient exactly how your email will benefit them or solve a problem they are currently facing.

5. Create urgency.

Use a deadline or limited time offer in your subject line to create a sense of urgency and encourage people to act quickly.

6. Avoid clickbait.

Avoid using clickbait-style subject lines that may be misleading or over-promising. This can damage your credibility and result in low open rates.

7. Include keywords.

Include specific keywords in your subject line to make sure it stands out in the recipient's inbox and increase the chances of it being opened.
