HTML Email Builder

About This Tool

I've this HTML email builder because I don't think marketers should write table-based HTML by hand. Email rendering across clients is one of the hardest problems in web development - Outlook won't support modern CSS, Gmail strips class names, and Yahoo Mail has its own quirks. This tool can't eliminate all those challenges, but it handles the heavy lifting so you don't have to.

HTML email (from HTML email) uses a subset of HTML for formatting messages. Unlike web pages, emails must use table-based layouts and inline CSS for maximum compatibility across clients. This builder generates email-safe HTML automatically.

For email rendering issues, the community at Stack Overflow - html-email tag is incredibly helpful. Discussions on Hacker News often cover the latest in email development techniques.
