51 Proven Subject Lines to Try in Your Next Email Campaign

Content marketing is all about creating a two-way conversation. Whether that conversation takes place in a social media inbox, in the comments of your blog or YouTube video, or through email – your priority as a small business owner is to attract, engage, and convert your target audience. 

But attracting attention in a crowded online marketplace is challenging! In email marketing, the best way to capture that spotlight is with an eye-catching subject line. So I’ve curated 51 of my best subject line ideas, tried and true from my own experience running campaigns for myself and my clients.

(I don’t blame you if you want to just scroll down for the master list! Get an even more digestible version of it, right here. But if you’d prefer a little context, keep reading…)

Why You Need Email Marketing

When someone gives you their email address, they’re entrusting you with space in their private email inbox. IMHO, earning an email address can be twice as difficult as earning a “follow” on your social media account – but I’d also argue that it’s 10x more valuable!

You see, you don’t own your social media pages.

All major social media platforms are operated by private companies that put their own bottom line waaaay ahead of yours. Platforms like TikTok, Twitter, and Facebook are under constant government scrutiny. You can get locked out of your account at any time (read this blog from my mentor and client Andrea Gribble about how to get out of “Facebook Jail”). 

And just because someone follows your page or account is no guarantee that they’ll see most – if any – of your posts, due to the platforms’ algorithms. 

That’s the harsh reality. But are you ready for some good news? 

Email marketing can be your secret weapon – because you own your email list!

Unless someone opts out from receiving messages from you, you’re able to reach them with valuable content that helps them, educates them, inspires them – and yes, sells your products or services to them.

A Note About Open Rates and Click Rates

Once your email hits an inbox, the next hurdle you need to cross is getting them to open it. That’s called your “open rate” and you should aim for 20% or higher.

Next, you want to keep them engaged enough to read the email and click something in it, such as a link to your website or offer. That’s known as your “click rate” and your target is 5-10%. Learning to write an effective email that sparks engagement and clicks will be its own article!
