Why are email subject lines so important?
According to OptinMonster, 47% of email recipients open your email solely based on the subject line.
And yet email marketing is still one of the most effective ways to reach out to customers and prospects.
But sending emails without a good subject line is a sure way to get them ignored or deleted.
Email subject lines are often the difference between getting opened and being deleted. To increase your response rate, you should optimize your subject lines.

How to write an email subject line with these 7 tips
Relevant, personalized, anticipated
In Seth Godin’s Permission Marketing book, he coined the 3 tenets of successful email marketing.
1. The email should be relevant to your readers.
Frase doesn’t send website conversion emails to customers who use our content creation and writing tool.
2. Personalize the start of the email body with “Dear Firstname,” however, many email marketing solutions allow you to insert the subscriber’s first name into the subject line.
Campaign Monitor reported that emails with personalized subject lines get a 26% boost in open rates.
When was the last time you waited impatiently to receive an email?
Not very often.
3. Anticipation is based on a hook, a tease to reel you in and make you want to read more.
If you want to build anticipation in emails, you need to make something interesting as bait to catch your reader’s attention and intrigue them into finding out what’s inside.
That’s why a good subject line is crucial.
Questions make good subject lines because people want to know the answer.
People love to find out the answers to questions, and that’s why asking questions in your email subject line is so powerful.
Provide something valuable in exchange for the time invested in opening your email newsletter.
When you create urgency in your subject line, the open rates increase.
Use this technique sparingly, though, as sending too many emails with urgent subject lines could be perceived as desperate.
Considering 21.33% is the average open rate for email newsletters across all industries, using curiosity can bolster your email campaign metrics.
Humans are curious by nature, and we’re wired to seek out new ideas, new products, and services.

Cart Abandonment Subject Lines
What is a cart abandonment email?

Customer Retention Subject Lines
If you have customers who haven’t opened your emails in a while, it might be worth trying a different approach.
