Most people have sent out at least one cold email — that's when you're not acquainted with the recipient — over the course of their careers. And if you haven't, don't get so comfortable. You probably will at some point, whether it's for business, networking, or applying to a new job.

Sending out a cold email can feel like you're sending your request or inquiry into a virtual black hole, especially when you don't receive a response.

There are several factors that can be credited to your email's success or failure. An online course called "Crack Cold Emailing to Increase Sales and Grow Your Business" teaches you how to compose a great cold email and, in doing so, up your chances of hearing back from the recipient.

In 59 lectures, this course covers everything from crafting a compelling subject line to following up to how to handle not receiving a response at all. It is taught by Scott Britton, a software entrepreneur whose startup Troops.ai was named one of the hottest startups in New York City this year. And we highly doubt Britton got to where he is today without sending out a cold email or two along the way. 

Usually the course goes for $195, but you can save 95% thanks to Udemy's site-wide $10 sale.
