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.
At worst, you might think I’m a bit weird for caring so much about sound quality. Or you might think I’m really weird if you knew that my loudspeakers are computer calibrated to my room. Or you might question my priorities if you knew I set up my office, so that my desk is nearly in the middle of it… mainly to be able to enjoy music better. But we’re all weird in some ways (and I’ll let you think this is the weirdest thing about me).
When you're using email as a marketing tool, you're working on a pretty personal basis. This isn't ‘drive-by' stuff -you're directly targeting customers from their inboxes. There's a huge amount of potential which comes with this kind of marketing... but you'll only reap that potential if you REALLY understand both the marketplace you're operating from, and the audience you're talking to.
