How to change your email signature

Short answer
Open your mail client's Signature settings, pick the signature to edit, replace the text or paste a new one, and save. Path depends on your client. Pick your tab below.
Which version do you use?
  1. 1

    Open the signatures panel

    New Outlook / Web: gear icon, Accounts, Signatures. Classic Outlook: File, Options, Mail, Signatures...
  2. 2

    Pick the signature

    Select the one you want to edit from the list.
  3. 3

    Edit or repaste

    Change text directly, or select all and paste a fresh one. Design one free in Wren.
  4. 4

    Save

    Click Save (Web/New) or OK twice (Classic).

Menu names occasionally move — look for Settings → Signature.

Same signature, everywhere you send from

Desktop and mobile signatures don't sync between clients, so updates are per-device. Practical pattern: designed signature on Outlook or Gmail desktop, short text on your phone.

Company signature? Ask your admin first

If your org uses a server-side signature manager, personal changes may appear alongside, not instead of, the company footer.

Common reasons a change doesn't stick

Almost always: forgot to click Save Changes; edited one signature but a different one is set as default; or changes wrote to a different Outlook profile.

One version of truth for a team

Doing it per person doesn't scale for a rebrand. Wren is built for teams: design once, everyone installs the same signature in two minutes, and banners update everywhere without reinstalls.

Common questions

›Why does my signature look different when I send it vs. edit it?
The editor renders your HTML the way that client interprets it. Gmail forces a system font in the box but sends what you pasted. Test to yourself and compare.
›Recipients still see the old signature on replies.
Most clients don't strip signatures from earlier messages in the thread. The old one stays where it was originally sent.
›Can I change signatures for my whole company at once?
Not from a personal client. You need an admin-managed tool (Exchange transport rule, Google Workspace App Script, Wren for teams).
›How often should I change my signature?
Only when the underlying info changes. Rotating a banner is what teams change monthly, usually via a signature tool.
›'Signature' vs. 'signature block'?
Same thing. Both mean the multi-line contact info at the bottom of every email.
