I was recently tweeted a great question and wanted to respond with slightly more than 140 characters. I figured @BenchmarkEmail deserved a complete response. So first and foremost, thanks for the
great question!

Content is a challenge for marketers today, largely due to our ability to target individuals via email so succinctly. But having the ability to identify these customers and not having
anything unique to say to them can have negative ramifications all the way around. So when you are planning your content, what types should you consider that will keep your subscribers wanting
more?
Realistically, what is going to resonate will be different from brand to brand, and even subscriber to subscriber -- but there are a few general areas we can focus on that will give a
broad audience something to dig into:
Visual Content
Email is a very visual channel -- but once upon a time, the inclusion of extensive visual elements in your email
program was frowned upon. The issues were typically related to file size, deliverability and ultimately loss of message due to image suppression. Today, however, the concerns are fewer and email
creative is really starting to stand out. “They” say a picture is worth a thousand words, and in email those words couldn’t ring truer. A compelling and relevant image can really
draw your subscriber in. It could be as simple as featuring a photo with a family. to relate to those subscribers who have kids.
Motion in Email
As with visual
content, we have made some significant advances for including motion (and interactivity) in email today. This has more to do with the inbox providers allowing a wider breadth of code to render in the
inbox environment than any coding advancements that have been made. Regardless, it is possible -- and effective. Including animated gifs, video, surveys and tap- to-interact content has demonstrated
lifts in email engagement of 40% or more for many brands (but clearly this is very dependent on the brand, the email and the content).
People Love Lists
Test after
test after test that I have seen demonstrates that lists work. People love lists. So consider the top three best ideas of the month, the top 10 most-posted pieces of content, and the top four
best-selling items of the month. It isn’t a tactic you should leverage daily as a content strategy, but sprinkled throughout the mix of other tactics, it can prove very engaging.
Community Content
Emails that include your customers via quotes, tweets, testimonials and images is content that gets attention. Showing the real-life use of products
provides a less marketer-centric, more customer-centric view, one focused on connecting with other like-minded subscribers.
I could go on and on about content that engages, but my final piece
of advice is that you have to be mindful of your content length. Too much of a good thing can turn bad really quickly. Knowing when to say when (while not a content type) is a content rule that will
help engage subscribers as well.
@Benchmark email, I hope this answers your question!
