In their own words
EmailQA
EmailQA helps teams review HTML emails by generating previews and collecting comments pinned to specific locations. Users can paste HTML or upload an.html file to create a shareable preview link. Emails render in Gmail, Outlook, and Apple Mail on real devices, with screenshots in light and dark modes. Reviewers can view and comment through a shared link without making an account. Teams can upload newer versions while retaining earlier feedback and comparing changes. Listed integrations include Mailchimp, Klaviyo, HubSpot, Constant Contact, ActiveCampaign, Campaign Monitor, ConvertKit, AWeber, Drip, and Figma. Email service provider connections use OAuth and read-only access; EmailQA says it reads templates without changing campaigns or accessing subscriber data. Slack can notify teams about comments, and users can reply in Slack threads. The REST API supports HTML uploads, real-device render requests, screenshots, and render-result webhooks; it is included in Business. The free plan is for individuals, Pro for teams and professionals, and Business for agencies and automation. Free is free; paid plans start at $20 a month. A 14-day trial is available.
