I recently had my MailChimp account suspended. One of my sites is in the ‘make money online’ space. It’s a completely legitimate website, but apparently if your emails contain keywords they don’t like, they will suspend you. I would not recommend using them. Contacting support I just get form responses that are completely unhelpful. There’s no phone support- just account termination. Really bad experience. Luckily, this is a very new site- but imagine if you have thousands of emails and they just shut you down without ANY recourse.
It's important to take advantage of the window of opportunity when your company or brand is at the top of your prospects' minds. You can really get a pulse of what future engagement will look like by what people do when you email then within 24 hours of their subscribing to your newsletter, signing up for an offer, and so on. Plus, it's a great opportunity for branding and setting expectations.
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.
