The problem is on Mailjet side which set Content-Type as mulitpart/mixed instead of multipart/related

Using Content-ID and cid for embedded email images in Thunderbird

You can see it in your own mail

Content-Type: multipart/mixed; boundary="=-+zpCN5rjhXag2yK+qwRs"
Reasons:
  • Probably link only (1):
  • Low length (0.5):
  • Has code block (-0.5):
  • Low reputation (0.5):
