In their own words
Email Accessibility
Email Accessibility checks email content against WCAG 2.2. Users send an email to a unique address and receive a report identifying accessibility issues. The service says its AI scanner checks more than 80 WCAG 2.2 criteria with 95%+ accuracy. Reports map findings to WCAG guidance and include severity levels, code examples, and suggested fixes. AI also extracts text from images and suggests alt text. Compatibility checks cover Gmail, Outlook, Apple Mail, and other major email clients.
The service accepts HTML from tools including Klaviyo, Mailchimp, Salesforce, Braze, Campaign Monitor, and Constant Contact. Supported inputs include HTML email files, builder exports, inline CSS, embedded stylesheets, images, attachments, and multipart MIME emails. It runs on the web. Free provides one monthly audit; Pro costs $10 a month, billed monthly, and includes ten monthly emails, with extra emails at $0.70 each. Enterprise pricing is available by contacting the maker. Content is retained for 60 days by default, with account settings configurable from 1 to 365 days. API access is listed as coming soon for Pro, and API endpoints are in development.
