Thank you for your submission. We have completed our review of “Virtuous - Responsive Email + StampReady Builder, Mailchimp Editor, 42 Modules x 5 Color Themes” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.

Any ideas why? ( I’ve tested it and it’s working on all specified platforms )

Thanks

I feel like some icons are quite outdated, the preview seems too busy - try to make it more clean, more separation between sections would be nice.
When I open an e-mail and it throws a lot of info at once, I immediately close and delete it.
Also I would remove the ‘read less’ - that’s not needed.
Icons are blurry, not crisp, you should fix that.
