Rdnext Signature Creator
Professional email signatures. Design, preview and install in one click.
Rdnext Signature Creator turns building an email signature into a few minutes' work. Toggle the blocks you want, add your details and branding, and the preview updates as you type, across desktop, mobile and dark mode.
When it's ready, it installs the signature for you: straight into Gmail or Outlook through secure OAuth, or as clean HTML and plain text to paste anywhere.

Frequently asked.
Which email clients are supported?
Signatures are built to render reliably across major clients, and you can install directly into Gmail and Outlook / Microsoft 365 with one click. For anything else, export the HTML.
Do I need to know HTML?
No. The visual block editor does everything. If you want full control, a raw HTML editor is one tab away.
Can my whole team share the same branding?
Yes. The Team plan adds a shared brand kit, locked styles and bulk deployment across your workspace.
Is my email data safe?
Installs use official, minimal OAuth scopes (Gmail settings and Microsoft Graph mailbox settings). The app only writes your signature and never reads your email.
