Please remember to configure all of the emails that Spree has provided to your needs.
Spree comes shipped with <a href="http://zurb.com/ink/" target="_blank"> Ink </a>
prepackaged, but you can use your own version. Ink is not placed in the asset pipeline.

<p>
Also take note that Gmail does not support <code><style></code> tags.
Therefore, you will need a gem that will be able to remove your <code><style></code>
tags and place them inline. Gmail only supports inline styles. We use
<a href="https://github.com/fphilipe/premailer-rails" target="_blank">Premailer for Rails</a> by default.
