Frequently Asked Questions
What is a free email signature generator?
A free email signature generator is a tool that lets you create a professional HTML email signature without needing a designer or developer. You enter your details, choose a layout, and get clean HTML code ready to paste into your email client — at no cost and with no account required.
What should I include in a professional email signature?
A professional email signature should include your full name, job title, company name, phone number, and a link to your website. A headshot or company logo adds credibility. Keep it to 4–6 lines — anything longer creates clutter and increases the chance of rendering issues on mobile.

Note: iOS Mail strips most HTML formatting. For the best result on iPhone, use a plain-text version of your signature or use a third-party mail app like Spark or Outlook for iOS, which support HTML signatures.
Why is my email signature not displaying correctly in Outlook?
Outlook uses Microsoft Word’s rendering engine for HTML emails, which strips many standard CSS properties. Common fixes: avoid background-image, use width attributes directly on <table> and <img> tags, and never use float or flexbox. This generator’s HTML is pre-optimized for Outlook compatibility.
Does a large email signature affect deliverability?
Yes. Oversized signatures with externally hosted images, tracking pixels, or excessive HTML can increase your spam score. Inbox providers like Gmail and Outlook weigh message size and HTML complexity when filtering. This generator produces lightweight, clean HTML that avoids those triggers.
Can I use this email signature generator for my whole team?
Yes. Generate a signature for each team member using the same template to maintain consistent branding. For organizations needing centralized signature management, a team plan lets you update all signatures from one place and push changes automatically.
Is this email signature generator really free?
Yes. Generate, customize, and copy your HTML email signature at no cost, with no account required. No credit card, no trial period, no hidden upgrade to unlock the HTML export.
