5 Proven Cold Email Subject Lines to Warm Up Your Leads

Writing cold emails is a challenge. If done right, they can be a very important tool for sales prospecting and customer outreach. Do it wrong, and you can get near zero responses and your emails will end up at the bottom of the junk and spam folders. A series of factors make sending cold emails an uncertain endeavor. Many people are unwilling to accept unsolicited communication. And many a time, you do not have all the information you need to engage your recipients.

How can you ensure your cold emails do not end up in the spam folder? Understand that your cold emails should differ from recipient to recipient depending on your driving channel or point of contact, where they are in the sales cycle, and so on. So, organize your email list accordingly. Do not send emails from your personal mail address and use your business domain instead. Also, this might sound trivial, but make sure you’re not using a “no-reply” email address, instead use an active reply-to address and make sure it is checked for replies regularly.

Most importantly, your email subject line, being the most prominent part of the cold email, should be well-crafted. It’s what your recipient sees first and, depending on how it is written, will determine if the mail will be opened and read, moved to junk, or ignored and left unopened. To help you get the best out of your cold email campaigns, here are 5 proven cold email subject lines to help your prospects warm up to you.

  1. “Hey [name], check this out”

This cold email subject line is the written equivalent of hearing your name called in a room full of strangers, only to look and find that it’s just someone else with the same name as you. Hearing our names tug at something in our consciousness and piques our interest in what someone has to say. And this cold email subject line takes advantage of that, appealing to the recipient in a tone that’s all too familiar to open your email.

  1. “A quick question regarding [project/goal]”

How do you feel each time someone asks you for advice about your turf in business? Good, isn’t it? Humans feel good about themselves each time someone presents the opportunity for them to express their expertise. This cold email subject line takes advantage of this human trait. It helps you put the email recipient in the position of the “expert” and offers the opportunity for them to showcase their expertise. Also, you’re adding to the pleasing effect by showing them that you value their opinion and believe that they hold the key to the solution of a problem.

  1. “[Name] recommended that we connect”

This approach works like a referral of sorts. The recipient perceives you as someone worth talking to if you mention an actual connection. Of course, you would need to do your research and find connections you can use, perhaps their colleague or superior officer. Even better if it’s a mutual connection. That way, it looks to the email recipient like you have been referred to them, inducing trust and making it more likely that they will open your email.

  1. “I’m hoping to help with [project/challenge]”

Out with “Always Be Closing”, in with “Always Be Helping”. With this email subject line, you are telling the recipient you have the means to help them solve their problems and are willing to help. Your prospects will appreciate your candor and willingness to help. As always, you need to do your research and find out what challenges your services can help the recipient overcome. Your email is less likely to get clicked if you offer to help solve a non-existent problem.

  1. “Where do I even start?”

This email subject line works because people often respond to something you have to say based on the level of emotion you’re putting into it. If someone sees that you’re excited about something, even if they’re not too happy about it, they will be tempted to reciprocate your excitement. So, when they see this subject line, their minds will go, “Start with what?”. They’ll like to see what has you so excited, and there’s only one way to do that – open your email. However, since this email subject line is abstract, you’ll need to make sure your opening words are specific and captivating enough while maintaining the same level of emotion.
