Hey @brit,
Great question!
At present, MMS responses to SMS/MMS you’ve sent aren’t supported through our Klaviyo conversations. Great attempt at using our Zendesk integration to mitigate this! Unfortunately, alongside Zendesk, our Gorgias integration would have similar troubles receiving MMS responses.
One workaround I’m aware of in order to receive an MMS response is being provided a link/URL of the media source. Because the link/URL would be responding as a normal SMS, you’ll be able to receive it under conversations and navigate to the link/URL to see the full media. Depending on what it is you were trying to achieve, in some cases, I’ve seen users set up some comprehensive SMS keywords which instructs users to upload their media to a hosting provider and respond with the sharable URL.
Thinking further on this, you can potentially setup an SMS keywords that providers your users a hosting link in order for your recipients to upload their media which would be directly accessible to you too.
I hope this helps!
