In September 2015, I was acknowledged by MailChimp for discovering bugs in their new 2015 Templates which helped the company to rectify these issues. I am a Mailchimp Partner Program member and MailChimp incorporates my HTML/CSS code which correctly renders in Outlook for client emails.

The quality of work Mariusz produces is exceptional. His templates are issue-free and render correctly across all browsers and platforms. If he does encounter design issues he’s careful to document and communicate them to me.
