When it comes to email marketing, the first thing you need to get right is the subject line. If you can’t get your subscribers to open your emails, it really doesn’t matter how good the actual email content is.

It’s easy to spend a lot of time crafting a great message and then just slap a subject line on it at the end. Spend some time writing them and see what type of headline gets you good open rates. Here are five tips to get you started.

Keep It Short

You want your readers to see the entire subject line before they click it. You also want to make it easy for people to scan through their emails. Try to get your point across in 50 characters or less. Pay attention to how your subject lines look on your own devices.

Another great idea is to keep a swipe file of subject lines that grabbed your attention. Even if the emails are on a very different topic, you can adapt them for your own needs.

Avoid “Spammy” Words

Stay away from using any words we all associate with spam emails. Words like “sale”, “discount”, “coupon”, “free”, “limited time offer” and even “reminder” are over used and even if they don’t trigger a spam filter and actually make it to your reader’s inbox, chances are high they’ll get ignored.

Instead, start by using the emails you’re saving in your swipe file and then go back and see what subject lines got the best open rates. Try to analyze why they worked well for your market. Not everything will work well in every niche. Find the types of subject lines that get your readers to open your emails and tweak from there.

Personalize It

While personalizing emails with someone’s first name has been overused in some markets, it still works well for many of us. Give it try and see if it works for you. Don’t overdo it, but use it when you really need them to open the email.

Depending on what data you collect when your readers sign up, you can personalize other things like their location for example. Seeing the name of your state or even city in an email subject line is sure to get your attention.

Pique Their Curiosity

We are all curious and it’s hard to ignore subject lines that sound intriguing or only tell part of the story. Using “…” at the end of your subject line will also work.

The idea here is simple. You want them to click and open the email to find out what the heck you’re talking about or how the story ends.

Frankly, the best tip when it comes to crafting compelling subject lines is to keep a swipe file of examples that got you to open the email.Use that as your guide for crafting your own subject lines.
