Hi Sam,

Lovely to hear from you. Quick note to confirm the kick-off slot for next Tuesday at 10am — I'll send a calendar invite shortly. Looking forward to it.

Anything else you'd like to cover, just shout.

Install instructions

        
      

      

        

          
          
          
          
        

        

          
    
            
  1. Click Copy HTML above (or Download .html).
    2. 
            
  2. In Gmail web, open the .html file in a browser tab and select all the rendered signature (Ctrl/Cmd + A).
    3. 
            
  3. Copy the rendered selection (Ctrl/Cmd + C).
    4. 
            
  4. Open Gmail → ⚙ Settings → See all settings → General → Signature.
    5. 
            
  5. Create a new signature, paste, and set it as the default for new mail and replies. Save changes.
    6. 
          

        

        

          
    
            
  1. Open the downloaded .html in a browser, select all (Ctrl + A) and copy.
    2. 
            
  2. In Outlook desktop: File → Options → Mail → Signatures → New.
    3. 
            
  3. Paste into the editor, name it, and choose it as default for New + Replies.
    4. 
            
  4. For Outlook web (OWA): ⚙ → View all Outlook settings → Mail → Compose and reply → New signature.
    5. 
          

        

        

          
    
            
  1. In Mail: Mail menu → Settings → Signatures.
    2. 
            
  2. Pick the account, create a new signature, paste anything in.
    3. 
            
  3. Quit Mail. Open ~/Library/Mail/V10/MailData/Signatures/.
    4. 
            
  4. Find the .mailsignature file you just made (sort by date) and replace its body with your downloaded HTML — keep the metadata header at the top.
    5. 
            
  5. Right-click the file → Get Info → tick Locked. Reopen Mail.
    6. 
          

        

        

          
    
            
  1. iOS Mail can't paste rich HTML directly. Easiest path: send yourself the signature in a Gmail email, open it on your phone.
    2. 
            
  2. Long-press the rendered signature → Select All → Copy.
    3. 
            
  3. Settings → Mail → Signature → paste. Then Shake to Undo once — this restores the formatting (iOS quirk).
    4.
