Most subscription sites know that diversifying revenue streams with events is a smart move. But how do you promote events to your subscribers effectively?

Numbered lists can be a great tool. We like this example from Publishing Business Conference for a number of reasons:

• The colored and bolded font gives it a more graphical feel while still ensuring readability across browsers.
• The colored font is also used strategically to make the email easier to read, emphasizing each list entry in blue and then really great selling points within some entries in red (Free kindle!).
• The subject line highlighting #7 and #8 ensures that even the busiest reader will see the most enticing selling points.
