14 Catchy Words That Start With “B” to Improve Subject Lines


“Boundless” suggests endless possibilities. When you use “boundless” in a subject line, it conjures up images of growth and expansion. It sparks the reader’s curiosity. What are you offering or recommending in your email to make them boundless? “Boundless” is a bold, bodacious word to include in an email subject line, and a bit of alliteration doesn’t hurt either.

Boost is one of my favorite, catchy words starting with “B”. You can use it in many contexts and signal the recipient that your email includes something which may improve his current situation. The word “boost” is optimistic and carries a positive energy load. Last but not least, it’s only 5 characters, which is especially important when keeping the subject line concise.

The word ‘believe’ has been widely used as clickbait in titles such as ‘You won’t believe…’. It works, but it has become cliched and may not align well with your brand. If that’s the case, why not try a slightly more subtle version in your email subject line? ‘Can you believe…’, ‘We believe…’ and ‘We couldn’t believe…’ are all good examples of using the word ‘believe’ to draw the reader into some kind of commitment to open the email and decide whether they agree or not.

“Best-selling” is a catchy word that works effectively in an email subject line for business. It attracts one’s attention to know more about the latest trends and whether they would want to avail it.

Stephen Keighery, Home Buyer Louisiana


“Buzzworthy” is a b-word that is sure to grab attention. If something is buzzworthy, that means it has the power to attract interest and attention. When people associate your product or brand with the word “buzzworthy,” they’ll view you as a commodity.

Rachel Blank, Allara


Bliss—the word itself inspires warm thoughts and an inspiring call to action. Check this out: “12 Ways to Lead a Life of Bliss,” “Blissful Triumph: How to Achieve Your Goals, “Electronic Bliss: Write Better Emails.” See? The word bliss is powerful as it is catchy. In the right context, this beautiful word can be a more attractive option than similar words like joy, pleasure, and happiness. “Bliss” is a great catchy word to use in email subject lines to convey emotion and build intrigue for the content in the message.

The word breathtaking is catchy and automatically puts a positive connotation on your email subject line. To take someone’s breath away means that, for a moment, they had no words and couldn’t even believe what they have heard or seen. The word breathtaking is mostly used to describe something amazing and is rarely (if ever) associated with anything negative. “Breathtaking” automatically makes you think of words like astonishing, magnificent and thrilling so you’d be hard pressed to find a better “B” word that embodies so much good.

“Breaking,” which is usually followed by “news,” has been a word that’s caught the eye of readers for generations. When readers see the word “breaking,” they already know what to expect next: something new, compelling, and often surprising. It’s a surprising word in and of itself–that something is breaking, or going wrong–which only adds to the element of surprise and noteworthiness. But obviously, since not all breaking news is bad, you shouldn’t expect that it will inspire anything in your readers but their attention to what’s coming next.

You probably worked really hard to ensure that your product, offer or pitch is the absolute best. Why not let your recipient know that? People are always looking for the top of the line, they don’t want to settle until they know that they found the best out of what’s out there. That’s why using the word “Best” in your email subject line might help catch your recipient’s eye and make them want to know more about what you have to offer. Make sure to save it for those truly top-notch offers and pitches, as nothing frustrates customers more than overpromising and under-delivering.

Betchya offers a challenge most people can’t refuse. Also spelled as betcha, betchya is the slang contraction of “bet you,” and expresses confidence or certainty that something is the case or will happen. Writing “Betchya’d love the new version of your favorite…,” or “Betchya don’t want to miss out on this limited-time discount” in an email subject line throws down the gauntlet, challenging readers to click open that email to find out precisely what you’re offering. By combining a dare with a hint of intrigue in your subject lines, you can bet on seeing a significant increase in your email open rates.

Simple, yet effective, burn conjures up strong emotions in the reader. Whether you’re telling them to “Burn up your to-do list”, “Burn calories” or “Burn bridges”, it can also be the set up for a false negative statement that then turns positive and cheerful. Like fire itself, it’s unpredictable and therefore irresistible.

Claire Trevien, Isoline Communications


‘Bizarre’ is a word that arouses curiosity. Subject lines featuring this word can leverage higher open rates if they make the reader curious to know more. For example, you could write headlines such as, ‘10 bizarre places you’d never believe exist’, or ‘The most bizarre reasons people got fired from work.’

Georgi Todorov, thrivemyway


The word ‘Be’ is a very powerful word which can be relentlessly used in email subject lines. Consider these examples: ‘Be bold and start your online business today’; ‘Be the start in your community’; ‘Be straightforward to safeguard your emotional wellbeing’.

Nauman Lodhi, Sorcim Technologies


Bonanza is a catchy word that can be used in the email subject line to grab attention. Whether you’re writing emails to customers as a part of your marketing strategy or dropping an email to the team to fetch attention, this word will certainly force the receiver to open the email once. The word means getting something desirable in a huge amount or a situation that creates a sudden increase in wealth/profits.  People link this word with discounts and offers and we all know how lucrative discounts are. April bonanza for employee of the month. Christmas bonanza for loyal customers. In both the examples, the word is enough to create a sensation among the receiver.
