How to Download Atellar
Atellar is available for download 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 bundles the versions for each platform in separate files, and each one should be imported into the corresponding tool.
With separate files for each sending platform and an editable PSD, Atellar fits email marketing workflows that change tools over time. Two limitations are worth noting: Outlook does not display background images, and the Gmail app does not apply responsive behavior. Outside those cases, the layout keeps the same structure on desktop and mobile, which speeds up production of each new campaign.
