This seems pretty straightforward. It’s about matching email metrics to your marketing objectives (remember them?) If it’s all gone well, your email conversion rates and financial metrics should track closely with your marketing objectives and customer journey. But, if it’s not doing that, don’t throw your hands up in despair! Look into the data, see what’s happened, work out why, and extrapolate some lessons for future campaigns.
Bloggers are the most obvious example of focusing on this email marketing strategy almost exclusively. SaaS (Software as a Service) businesses are another group that typically heavily emphasize content emails. Of course, bloggers, SaaS businesses, and everyone else can send content emails while also using the other email marketing strategies. And you should do it, too.
The downside of just making offers is that they’re not useful on their own. People on your list won’t receive any value from you unless they buy what you’re promoting, so they have little reason to stay subscribed. That’s why this email marketing strategy doesn’t work alone. And it’s why many e-commerce sites struggle to keep people interested. There are a few exceptions (e.g., Groupon) that rely entirely on making offers—but then the reason people joined the list was specifically to receive those offers.
