Responello

Outlook guide

How to add a button to your Outlook signature.

Copy the finished button from Responello and paste it into the Outlook signature editor, a single email or your automatic reply. Pick your Outlook version below.

Install it in your email program

Choose where you use the button and which email program you use. The steps and the animation follow your choice.

Where will you use it?
  1. In Responello, click Copy button.
  2. Open Settings › Accounts › Signatures.
  3. Select Add signature, give it a name and paste the button into the editor.
  4. Choose it for new messages and replies, save, and send yourself a test email.

With a Microsoft 365 or Outlook.com account, signatures are usually stored in your mailbox and shared across Outlook apps. If the button is missing in another Outlook app, paste it there too.

Official help: Add a signature in Outlook on the web

Choose your Outlook version

Outlook on the web and the new Outlook for Windows use the same signature settings. Classic Outlook for Windows and Outlook for Mac have their own signature window.

  • With a Microsoft 365 or Outlook.com account, signatures are usually shared across Outlook apps.
  • If the button is missing in another Outlook app, paste it there too.
  • Automatic replies need a Microsoft 365, Exchange or Outlook.com account.

Test before you rely on it

Send a message to another account and open it in the Outlook version your recipients use. Open the button, submit the request form or complete the confirmation, and check that the notification arrives in your connected channel. Opening the button alone does not send an alert.

  • Check colours and spacing in the delivered email.
  • Expect square corners in classic Outlook for Windows.
  • Replace the button wherever you use it after changing its design.

Practical notes

  1. The preview in the classic Outlook signature window can differ from the sent email.

  2. Enable the plain-text fallback link if recipients may read emails in plain text.

Put a button where the moment matters.

Create a button, choose where the signal should arrive, and test the complete confirmation flow.
