Hello,
We use Freshdesk api /api/v2/tickets/ticketId/reply
To create reply to tickets using the above API. We send an HTML content to freshdesk which includes the following as the first line the body tag.

The FD receipt app works fine if I send an email from Freshdesk directly using Canned Templates.
But does not work when we send an email from our API. Even our after opening the email the tag unread is not removed
