Email Design from OpenTable

I very much like the new¹ confirmation email design from Open Table. This design is clean:

• It clearly presents the most important information (when and where your reservation is) and provides clear callouts to add to your calendar, share, change your reservation or cancel.
• The design also scales from small screens to large screens with some light responsive techniques.

After the important information there is quite a bit of advertising, but because it is after the relevant information it doesn’t detract from the overall experience.
