Writing a good subject line for email marketing is more difficult than crafting the email itself. A compelling subject line gets your email opened; a poorly constructed subject line can get your email immediately spam-filtered, or worse yet – deleted upon receipt.

To reduce these infractions, we put extraneous efforts in writing the perfect subject line, but it doesn’t have to be that painful.

Here are our top three tips on crafting the perfect subject line to increase your open rate for your next e-marketing campaign:

Clearly state what’s in the email

Email subjects tell what’s inside the email; the body of the email is what’s going to sell it. Make sure it is relevant, valuable, and that the subject line message is clear to your audience.

Use descriptive words to clearly explain what is in the body of the email.

Pro Tip: Be visually different by trying square brackets, using capitalization, phone numbers or quotes.

Keep it short

Descriptive subject lines don’t have to be lengthy. By using the right words, you, too, can follow the aforementioned suggestion by clearly stating the email’s value.

More importantly, your recipient will likely open your email on a mobile device therefore, only visibly showing 4-7 words across the screen, at best. Not only is it wise to keep it short, but it is technologically sound.

Pro Tip: A good rule of thumb is to keep the subject line to less than 50 characters.

Ask a question

Asking a question in your email subject line inadvertently creates a call to action [CTA], the end user is more likely to seek the answer within the email, or inadvertently respond to the question without eliciting a response.

Pro Tip: Asking a question creates a sense of urgency. Try using it in your next e-marketing campaign.

Time spent on thinking of a good subject line is time wasted. Test subject lines when you can to see what resonates with your audience.
