Tips To Write Appealing Subject Lines

Nowadays, people are overloaded with emails. In order to make sure your email gets noticed, you need to craft a subject line that’s appealing. Here are some tips to help you write subject lines that will get people to open your emails:

1. Keep it short and sweet.

People are busy, so they don’t want to see subject lines with multiple sentences or long phrases. Keep your first line short and sweet without 1-2 words, because if you’re able to catch your reader’s attention at the beginning.

2. Personalize it.

Make sure that you personalize your subject line as much as possible. If you want to make a direct appeal, use a name in the subject line. If you’re interested in a topic and would like for someone to share their thoughts with you on it, make that your subject line. Personalization is the best way to grab people’s attention because it makes them feel important, so they are more likely to open your email.

3. Be specific.

When crafting subject lines, be as specific as possible because this will allow you to clearly define what your email is about and what the reader should expect when they open it. The more clear you are, the less likely your reader will have questions that could lead them to not open your email at all.

4. Use a sense of urgency or intrigue.

Including a sense of urgency or intrigue in your subject line is another great way to make sure your email gets opened. Urgency can be created by using phrases such as “important,” “critical,” or “time-sensitive.” Intrigue can be created by making a statement that intrigues the reader, such as “how does this affect you?” or “what do you think of this?”


This is not the first time I have written about email subject lines that work. And, it won’t be the last. The reason for this is simple – there are so many different ways to write a compelling subject line and they all depend on what you want your reader’s response to be when they open up your message in their inbox.
