Best email subject line styles

1. Action subject lines:

A subject line that requires action will draw people’s attention. Passive and dull subject lines would bore people. People like energy, people like something that will be worth their time. You should leverage that while writing your email subject lines.

Examples: If your shoe company is running a discount and you write something like

“Shoe sales discount!” as your subject line, it will not give much open rate as an active sentence like

“Get a 15% discount on any shoe you buy!”

Although, it is not advisable to use too much action on your subject lines in order not to give the wrong message. You don’t want to sound like you’re forcing your subscribers to do something for you.

2. Exclusive information subject lines:

Always use subject lines that make your subscribers feel special. Let them feel they are not treated as others. Be sure to be authentic, nobody wants to be lied to.

Examples of these subject lines include; “For our esteemed customers”, ” Discount only for you!”, “Exclusive information”, ” private invitation”, etc.

Be cautious while using this type of subject line. Too much zeal would sound too salesy and could be misconstrued as spam. People don’t like spammy messages in their inboxes.

“Free product offer for the next 10 days!”, “Free coupons for you if you buy now!” etc.
