When it comes to email marketing campaigns, making sure that yours are opened is serious business. With 47% of subscribers opening emails purely because of the subject lines, this is a crucial area to focus on when creating your email campaigns. Consumers receive an average of 99 emails every day from different companies, so there's fierce competition to get noticed.

Check out these 5 tips to learn how to write subject lines that truly stand out in the inbox. 

Start off with numbers or action verbs to pique readers’ interest and get them excited to open up. Numbers are persuasive and easy to read, while action verbs can inspire people to, well, take action. Whichever direction you choose, make your emails look more prominent by writing your subject lines in title case. Just Like This.

Over 71% of people open marketing emails on their mobile devices, so create subject lines that won’t get cut off. Use 40 characters or less to make sure your message is seen.

Hosting an event or sale? Encourage people to open your email by creating a sense of urgency in the subject line. Tapping into the all-too-human “fear of missing out” will give them more of a push to click right away and not put it off until it’s too late. Plus, you could boost your open rate by 22%. 

Stay away from using all-caps in the subject line. It looks suspicious, and can make it seem like you’re YELLING. And don’t go near typical spammy trigger words like ‘prize’, ‘money’ and ‘$’. 

As carefully crafted as your subject lines may be, don’t forget to personally try them out. Always send a free test campaign to your email address and ask yourself: Does the subject line make you want to open the email? Does it give you a good sense of what to expect in the email itself? Test driving this content before you actually send your campaign to your subscribers will help you perfect your message ahead of time.
