Every booking in Sirvoy includes a log that shows the status of emails sent to the guest, usually Delivered or Delivered & Opened. But sometimes, the email stays marked as Delivered, even when the guest has opened it.

Why an email might not show as opened

• The guest’s email provider doesn’t report opens. Some providers don’t track or share whether an email has been opened. In those cases, even if the guest opens it, Sirvoy won’t receive that update.
• The email didn’t reach the guest’s inbox. Some domains—like @guest.booking.com—may block emails before they reach the inbox. For example, Booking.com might filter out emails with pasted screenshots or hyperlinks. To avoid that, use the Insert image option for screenshots and consider removing links from the message.
