Overview

Emailyy is a free, browser-based suite of email utilities designed for creating, checking, formatting, and testing email content. It bundles five practical tools into one simple site: an Email Signature Generator, Email Subject Line Tester, Email HTML Preview, Email Word Counter, and Email Header Analyzer. The platform requires no signup, no credit card, and no software installation, making it useful for quick email production and troubleshooting tasks.

Key Features

• Email Signature Generator: Build a professional HTML email signature with fields for name, job title, company, phone, email, website, address, photo/logo URL, LinkedIn URL, accent color, and font. It includes a live preview, copy-signature, and copy-HTML options for Gmail, Outlook, Apple Mail, and other clients.
• Email Subject Line Tester: Check subject line length, character count, readability, and approximate appearance in desktop and mobile inbox layouts. Supports optional preheader text and sender name.
• Email HTML Preview: Paste HTML email code and preview it in desktop, tablet, or mobile widths. Scripts are blocked, remote images can be blocked, and the page states nothing is sent to a server.
• Email Word Counter: Count words, characters, sentences, and paragraphs in email copy with live updates.
• Email Header Analyzer: Paste a raw email header to inspect delivery information, timestamps, mail servers, authentication results, and routing. It reads the pasted text only and does not connect to an email account.
• No-friction access: All tools are free, browser-based, and usable without registration or installation.

Target Users

• Email marketers who need to test subject lines and preview campaigns before sending.
• Sales, support, and operations teams that want consistent professional email signatures.
• Developers and designers who need a quick sandboxed HTML email preview.
• Freelancers, small businesses, and creators who write emails regularly and want lightweight formatting and counting tools.
• Anyone troubleshooting email headers or checking basic delivery and authentication information.

Unique Selling Points

• All-in-one free email toolbox: Covers signatures, subject lines, HTML previews, word counts, and header analysis in one place.
• No signup or payment: Open a tool and start using it immediately, with no subscriptions, credits, or paid upgrades.
• Browser-based simplicity: No downloads or installs required.
• Privacy-conscious previews: The HTML preview runs in the browser, blocks scripts, and can block remote images; the header analyzer does not connect to your mailbox.
• Practical inbox previews: Subject line tester shows approximate desktop and mobile layouts, helping users avoid overly long or poorly formatted subjects.
