Hey @rivermile,
Thanks for reaching out!
Yeah, the QR code is actually an image and some email clients have a tendency of blocking images by default. This is something the recipient can resolve by changing the preferences in their email application to accept images by default or those in email from specific senders.
We are planning to include an option to attach tickets to emails as a PDF. I’m not exactly sure where that is in the roadmap, but I see that the feature request has been marked as planned.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
