Email Signature Builder — HTML and plain text — OnePassApps

Create a contact signature, copy formatted HTML or plain text, and follow desktop Gmail, Outlook and Apple Mail setup examples.

Email Signature Builder helps you compose a small contact signature and transfer it into your mail client's settings. Edit the example details, choose a layout and check the rendered preview. The app produces formatted content, HTML source and plain text; it does not connect to your mailbox or send messages on your behalf.

What you can do

  • Choose a classic or accent-line layout and enter contact details, multiline addresses and closing text.
  • Copy the formatted signature, its HTML source or a plain-text version for different mail-client needs.
  • Download standalone HTML or TXT when clipboard access is unavailable, with desktop mail-client setup examples.

Limitations

  • Contact fields stay in tab memory and disappear on navigation or reload. There are no remote images, tracking pixels, mailbox connections or automatic installation.
  • Mail clients may rewrite HTML or apply their own styles. The examples help with setup but do not promise identical rendering in every client or message thread.

Is Email Signature Builder free, and do I need an account?

Yes, it is free. Email Signature Builder runs in your browser with no account or payment details, and it never uses OnePassApps credits.
