Testing
Email on Acid
Email previews and pre-deployment QA across 90+ clients.
overview
Email on Acid (now part of AWeber) provides client-rendering previews, accessibility checks, link validation, image and load-time analysis, spam testing, and a campaign precheck workflow. Direct competitor to Litmus with broadly similar coverage and typically lower entry pricing.

not great for
Teams already standardized on a sending platform with built-in previews.
