Getting started shouldn't be daunting. Generally, you'll know right away whether you like a user interface (UI) or not, and most of the contenders we reviewed offer free trials so you can poke around before dropping any cash. Luckily, most of these services have modern-looking graphics and uncluttered layouts. These are not the complex business software UIs of yesterday. Be careful, though, as some free trials require a credit card. This means you need to be sure to cancel your trial before you're billed if you're not happy with the service.
Another way to extend the clicks on your email beyond its shelf life is to prompt your audience to forward the offer. The folks at Litmus found that the most forwarded emails were 13X more likely than the typical email to include “Share With Your Network” calls-to-action. By including forward-to-a-friend (or social sharing links, as we discussed above), you put it in recipients' minds to share.
