Design, Code, Email Delivery tests
I specialize in creating Mobile Responsive Newsletters, Templates for MailChimp, SalesForce, Pardot, Klaviyo, Active Campaigns, Campaign Monitor, Constant Contact, Aweber, iContact, and numerous others.
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.
