How to Download Sentinel
Sentinel is available for download right here at Ultrapack. The step-by-step guide for using this file is in the How to install tab, next to the description. The package includes the versions for each email platform, the PSD, and the documentation.
Sentinel brings the StampReady, Mailchimp, Campaign Monitor, and HTML versions together in a single package, so you don’t have to rebuild the layout every time you switch sending services. Two limitations of the email clients themselves are worth keeping in mind: Outlook does not display background images, and the Gmail app does not apply the responsive layout. Aside from that, the template keeps a stable structure in the main desktop and mobile readers.
