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.
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.
