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.
Calculators: A calculator offers customers a lot of value with minimal effort on their part and instant gratification. Even a simple price calculator (e.g., “How much does it cost to buy a house?”) can have impressive results: companies report lead conversion increases of more than 25%, plus a nice boost from social traffic. Offering a calculator as a call-to-action is a sign of your intent to solve a customer’s problem and add value, boosting your brand image for customers who aren’t ready to commit.
For example, you may analyse the journeys on your website and identify that people who visit a page is more likely to purchase than those who do not visit that page. With behavioural data pointing towards the potential for this page, it would be worth testing whether offering a bespoke content message or discount offer to users when they arrive at that page drives conversions. It could be that your customers have left items in their baskets and not completed their purchase, like this example here from Nordstrom:

Be clear about what people can get and how to get it. This is the backbone of this email marketing strategy. Tell people about the benefits they can get. Write a separate email about each major benefit, if you want. Make sure those benefits come out clearly. But also keep it conversational. Don’t just list a bunch of benefits and expect people to buy. Also, remember to be clear about what they need to do to get those benefits. Tell them to “click here” or “apply for a consultation.” Don’t force people to think about how to move forward. It’s not that they couldn’t figure it out. It’s just unnecessary (and therefor annoying) when you could make it easy for them.
For example, a young company experiences growth and considers purchasing an employee health insurance plan but knows little about options. A health insurance company offers an online quiz with questions such as what state the company resides and what employee health benefits laws apply based on the number of employees, what to look for in health insurance offerings, etc.
Two particularly important groups for our purposes are customers with a one-time purchase and customers who have purchased multiple times. A customer is sometimes not considered to be loyal or repeat customer until they have purchased two to five times, in which case the single purchase segment is more akin to a warm prospect than a loyal customer.

Alternatively, at least, an eye-catching design. It’s worth letting a proper designer have a go at prettifying your emails. Customers are often opening emails on the go, so you need to work hard to grab their attention. Making your emails nice to look at is a brilliant way to hold their eye. Netflix put time and effort into making their emails stand out, personally and visually – and it pays off for them!
