Whether you're a business owner with a team of two or a team of 200, one of the things that never seems to change is the need to send out cold emails. From sales emails to press pitches to intro emails, cold emailing seems to simply be a necessary evil for entrepreneurs.

Yet, despite the importance of cold emails, very few entrepreneurs I've met and spoken with are using apps and tools to optimize this otherwise boring process. That's exactly why I compiled this list of five resources to help you become an emailing expert in no time. Here they are.

1. Bananatag

Ever wonder whether or not your cold email was opened, sent to spam or ignored altogether? With tools like Bananatag, an app that tracks your emails after you send them out, you'll be able to have your answer immediately.

On a personal level, I use Bananatag to make sure my most important messages were opened by the person I'm targeting. If the emails were opened but no response was given, I'll follow up a couple days later to spark things up again.

Bananatag allows you to track up to five emails per day for free. If you'd like to track more, you'll need to upgrade.

2. Canned Responses on Gmail

If you aren't using Canned Responses in Gmail, you're missing out on a huge time saver. Canned Responses is a free Gmail feature that lets you quickly create email templates you can plug into your text editor. This will enable you to spend less time copying and pasting or writing standalone emails altogether.

To activate Canned Responses, simply log into your Gmail account, click Settings and then go to the Labs tab on the right-hand corner of the web page. From there, scroll down to Canned Responses, click Enable, save your changes and you're good to go.

3. Hunter Chrome Extension

Generally speaking, when it comes to cold emails, the more you send out the more likely you are to snag a deal, so speed is key. Additionally, digging up the emails of targets you're trying to find is a time-consuming endeavor, which is why the Hunter chrome extension is such a useful tool. With Hunter, you can automatically scrape up emails from any website of your choice, easily copy and paste the email address and send your email out.

4. Neil Patel's Guide on Writing Headlines

To get your cold emails read, they must first get opened--problem is, getting them opened isn't easy. This is why writing clickable, intriguing subject lines for your emails is so crucial to successful cold emailing. Luckily, marketing mogul and fellow Inc.com columnist, Neil Patel has written a comprehensive guide on how to write captivating headlines your targets will want to open. 

One tip that has worked wonders for me and resulted in my highest response rates is leveraging social proofing in my email subject lines. For instance, one such headline from a sales campaign I sent to blockchain public relations agencies was this: "Quick Question From an Entrepreneur, Successful Blockchain Writer & Fellow Crypto Nerd". 

Think critically about what credentials you can leverage, then find a way to cleverly insert it into your email headlines.

5. Boomerang

Boomerang is an email app that allows you to pre-schedule your emails to be sent sometime in the future. I love this tool because I often find myself sending cold emails out at odd times of the day in my pajamas, spoon of cereal in hand. Sending an email to a busy person at 3am doesn't only seem creepy, it's much less likely for the target to open and respond to than an email that's sent at a more optimal time. With Boomerang, you can send emails at any time of the day, no matter how crazy your schedule is. 

No matter what kind of business you run or are a part of, getting the most out of your cold emails will lead to more sales, connections and ultimately a longer lifespan for your company. To take your emailing game to the next level, start by downloading and using the tools laid out in this article. Best of luck.
