Crafting the perfect newsletter requires a lot of effort. You spend a lot of time over an ideal email copy, embedding the correct links, designing it properly, and strategically placing your call-to-action to nudge your subscribers to take action.
But it can all go down the drain if the email is not even opened. Research shows 33% of email recipients decide to open an email based on its subject line. Another 69% of respondents confessed they would report an email as spam after solely reading the subject line.
It is, therefore, essential to include well-thought subject lines in all your emails. A great example of catchy subject lines is newsletters from Glitter Guide. The company sends lifestyle-related newsletters to its subscribers.
Considering there is a new trend to talk about every day, Glitter Guide identifies a need for freshness in all content related to it. So, it connects the newsletter headlines with the latest news to ensure its readers find the newsletter relatable and click-worthy.
Similarly, you must study your audience well and test what works for them. But a universal fact is that most inboxes where your newsletter lands are already overflowing with emails. So, you must ensure your headline stands out among them.
A great subject line comprises numbers or data, a unique rationale, attention-seeking information, and a promise. To create a catchy headline for your newsletter, you must balance creativity with customer knowledge to get optimum results.
If all this sounds like too much work, technology has got you covered. Email subject line testers are tools that come with various features and use advanced tech to help you quickly write the best headlines. These tools consider multiple aspects of a headline that impact your audience.
They measure the usage of emotional words, keep words that trigger spam filters at bay, and suggest the perfect headline length. GeekFlare explores eight incredible tools:

Tips to remember to write converting email headlines
So, as you have realized the importance of a perfect email subject line and how it is essential to get a higher open rate, let us take a look at how you can create one quickly:
#1. Include an actual person’s name in the subject line
It instantly makes the email content more personal. You do not want your subscribers to think they are receiving emails from a bot. There is a human being sending out those newsletters, after all. So make sure you keep that informal connection steady by using the person’s name in the headline — similar to what Licious did in an email to me—a subscriber.
#2. Use power words
Absolutely! Words like “inspire,” “only for you,” and “faster” are powerful as they instantly grab the attention of the email recipient and create a sense of urgency for them. Of course, the use of power words depends on the context of your email. So if you think you can do away with them, keep your email headings short and simple. Otherwise, you can also use high-conversion words as shown below:
#3. Test your subject lines before sending
Use any of the above tools we mentioned previously to optimize your email subject lines for conversion. You might get some right and also write poor email headings at times. These testers will ensure that only quality subject lines are used in your newsletters.
#4. A/B test your subject lines while sending
You could come up with a thousand email headings, but to ensure your subscribers like them enough to open your email, you must A/B test them. Email service providers like ActiveCampaign, SendGrid, and MailChimp can guide you through the split testing process.
#5. Do not forget about emojis
Research shows 92% of online consumers use emojis every day. With over 10 billion emojis sent daily, this is not surprising at all. So why not use them in moderation in your email subject lines? Copy-paste relevant emojis from sites like GetEmoji.com and use them in your content.
Of course, do not go overboard with the number of emojis used. Treat them as garnish and only add them when it makes sense or when they support your message. The idea is to get noticed, not send mixed signals to your email recipients.
Over to you
Regardless of your industry, writing quality email subject lines is essential. Thankfully, there are tools to help you sort out and improve your open rates significantly. Your email subject lines have the potential to increase user engagement and shareability rates — bank on them, work hard on them.
