Zoom branded invites for Google customer environment - only plain text shows in gmail

Hi ​@Mike Kaniff,

Thank you for joining Zoom Community! If the invite preview looks branded in Zoom but the email your customer receives is plain text, that usually means the recipient’s mail system/client is delivering the text-only version (or stripping HTML), not that Zoom failed to apply branding.

For Google Workspace customers, check these common causes:

1. Recipient is viewing the “plain text” part of a multipart email

• Many invite emails are sent as multipart (HTML + plain text). If Gmail decides to display the text part (or an intermediate gateway strips HTML), branding won’t appear.

2. An email security gateway is stripping HTML

• Even if they use Google Workspace, they may also have a third-party security layer (Proofpoint, Mimecast, Barracuda, etc.) that converts inbound mail to plain text.

3. Gmail settings / client behavior

• Some clients/extensions force plain text display, or the user may be using a client that prefers text-only.

What to do next (quick isolation steps)

1. Have the customer open the same invite in Gmail web and use “Show original”
   • Confirm whether the message contains an HTML part. If “Show original” indicates only text/plain, then something upstream is removing HTML.
      
2. Send the same branded invite to:
   • a personal Gmail address (outside their domain), and
   • an address on a different domain (if possible) If those show branding, the issue is almost certainly on the customer’s mail handling side (policy/gateway/client).
      
3. Ask their Google Workspace admin to check:
   • Gmail compliance/routing rules that modify messages
   • Any inbound gateway that rewrites or converts messages
