O2K Email Signature Builder

Builds a lightweight, table-based HTML signature with hosted images, so mail filters see text plus linked images instead of heavy embedded attachments.

Banner

Upload the banner to your own website (same domain as your email) and paste its public link here. Copy signature keeps the hosted link, so the banner shows inside the email like a normal signature — it never becomes an attachment. Copy HTML gives the same markup as source for Outlook desktop's signature box.

Preview only:

Choose the banner file to preview it here and check its file size. It is not embedded in the signature.

Social links

Links show as round clickable icons. Leave this empty to use the icons hosted on this site — they stay inside the signature when pasted instead of turning into attachments. Set this only if you host the icon files yourself: https://<your-site>/icons/

    A clean signature lowers the score, but most "lands in spam" cases come from domain authentication. Ask whoever manages office-2000.com DNS to confirm these three records:
    
        
    SPF TXT on root
    Lists every server allowed to send as your domain, e.g. v=spf1 include:spf.protection.outlook.com -all for Microsoft 365.
    
        
    DKIM CNAME / TXT
    Turn on DKIM signing in your mail admin console and publish the selector records it gives you.
    
        
    DMARC TXT on _dmarc
    Start with v=DMARC1; p=none; rua=mailto:dmarc@office-2000.com, then move to quarantine once reports look clean.
    
        
    Test a real email by sending it to the address shown at mail-tester.com, which reports SPF, DKIM, DMARC and content scores together.
