If you setup AMP email / Get approved.
Will your subscribers still need to "approve pictures from sender" or will images be automatically loaded?
Just trying to understand, if it's worth the hassle.
For Gmail, the "Dynamic email" feature will only be enabled if the image setting is set to "Always allow external images". If the setting is set to "Always ask" (which would be the case in your question), then AMP emails will fall back to static HTML/plain text emails.
You can see a short blurb about this fact in the description of the image setting in Gmail. Also see the HIDING_IMAGES fallback reason at https://developers.google.com/gmail/ampemail/debugging-dynamic-email.
