Minimal risk: Some top marketers expect to burn through $10,000 of advertising budget before even knowing if they can make a campaign profitable. (Nope, that’s not an exaggeration. But I’d usually aim for a few hundred dollars—not thousands.) With email marketing, the costs are much, much lower. A simple email marketing software like AWeber is very affordable even if your business isn’t a huge success, yet. And even if you go with something advanced like Infusionsoft, you’re still far away from the kinds of investments many other marketing tactics require. Sure, email marketing and advertising aren’t directly comparable (advertising is mainly used to reach new prospects). But you get the point.
Sample review: “See what happens to your emails after you press send…you’ll know exactly when they opened your email and whether or not they clicked on your link. BananaTag will even tell you whether they’re on their desktop or mobile device. And best of all, your email appears NO different to your contacts. All of the tracking is done seamlessly without any change in the user experience.” — BuzzBlogger
