Email Template Builder

Turns HTML email templates into plain text versions and validates both formats before sending. You'd reach for this when you need to maintain both rich and fallback email versions without manually writing the plain text variant every time. It handles the annoying parts of email preparation like stripping HTML tags intelligently and checking that links, formatting, and basic structure survive the conversion. Honest take: it's one of those unglamorous tools that saves you from repeatedly solving the same problem, especially if you're building transactional emails or newsletters where deliverability matters and some recipients still prefer plain text.
