Beyond that, avoid using all caps, too many exclamation marks, and hyperbolic phrases ("ACT NOW BEFORE TIME RUNS OUT!!!!"). Poorly formatted HTML in your emails can also hurt how they’re handled. Every spam filter is different, so an email might pass through one filter but get flagged by another. For more comprehensive info on how spam filters work and how to avoid them, check out this guide by MailChimp.

People tend to think of evaluation as something you do at the end of a campaign. In fairness, doing a full evaluation at the end is a massively important part of any campaign strategy. But it’s also helpful to evaluate as you're going along. Lots of brands make the mistake of closing their ears to ongoing issues and save any feedback for the end of campaign evaluation.


Think about mobile. If a campaign doesn't show up on mobile devices, it's not going to perform very well. Everything you send should be mobile-friendly. Check out ReturnPath's "Email in Motion" infographic for some data that might affect the way you design your emails. One of the highlights: According to the study, 63 percent of Americans and 41 percent of Europeans would either close or delete an email that's not optimized for mobile. Might be time to start using a responsive template.
The takeaway here is that if you are to use personalization as an email strategy, do so in a meaningful way. It takes little knowledge or relationship to place someone’s name in your greeting. It shows far greater care to send personalized email that is specific to a recipient’s needs and history. Again, an example from my inbox, this email from Rdio dispenses with the formalities and simply provides an update on music I actually listen to.
“I love the quality I received from the solo ad I purchased from Elad. I ordered just 50 clicks and received 70, not only that, 56 of the clicks were from USA. It’s like buying a 100% tier 1 ad. I got 2 sales right away and 17 opt ins, and 2 more sales on back end. Never had this much success with a 300 or even 600 solo ad but a 50 click test run blew me away! Definitely going bigger next time and my repeated business is a must!!! Great Job.”
Technology has a significant impact on consumers’ expectations, and those expectations impact how subscribers engage with your email marketing. Brands need to continually demonstrate that they know their customer, which can make it a challenge to stay on top of the evolving context of marketing. An email strategy can make all the difference between building a relationship with your customers and sinking without trace.
