Quick Tips To Write Subject lines that generate Sales

How would you feel if your hard work to write a good subject line is a flop? I bet it will frustrate you. As a matter of fact, I have experienced such situation before and it’s really frustrating when nobody clicked on the link after spending so much energy to come up with an interesting title.

But such kind of situation is not uncommon. Most email marketers are experiencing the same thing. Are you ready? Let’s do this!

1. Create urgency

One of the best ways to get people to take action is by creating a sense of urgency. You can do this by adding words like “now,” “today” or “limited time offer.”

2. Use numbers

People love numbers. So, if you want to convince your subscribers to click on your subject line, use numbers in it. For example, “25% off today only!”

3. Tease them

Another way to get people to take action is by teasing them. You can do this by giving them a glimpse of what’s inside the email. For example, “You don’t want to miss this!”

4. Use positive adjectives

When writing your subject line, use positive adjectives that will make people feel good about what they’re going to get. For example, “amazing,” “incredible” and “unforgettable.”

5. Make use of word hacks

Word hacks are common phrases that most people use in their daily lives. If you incorporate these words in your subject line, it will make your email more relatable to them. For example, “dinner’s on me,” “yesterday’s news” and “new year new you.”
