Free browser-based tools for email signatures, subjects and headers

About Emailyy
Emailyy is a set of free, browser-based tools for working with email content and technical email details. It is aimed at marketers, professionals and anyone who writes or checks email and wants a quick answer without creating an account.
The current tools cover an HTML email signature generator with copy-ready output, a subject line tester that shows length and readability, an HTML preview for pasted email code, a word and sentence counter for email copy, and an email header analyzer that reads delivery details, timestamps, mail servers and authentication results.
Each tool handles one specific task and needs no signup, credit card or subscription. Because the tools run in the browser, there is no software to install, and the header analyzer does not require connecting an email account.
