Email is a powerful tool for the modern marketer, but it’s easy to lose sight of its importance when juggling responsibilities. Before you know it, your meticulously-crafted emails can end up in junk folders all over the globe without ever being opened.

What’s worse, recipients may mark your emails as spam. When this happens, your mass marketing campaign may struggle against spam filters of major email providers.

Open rates may plummet, and all that time and effort will go to waste. Not to mention, you may end up with a poor return on investment (ROI).
