Thank you for reaching out to us through the Community. That's a great question! As of now, we do not currently have a limit of how many images you can insert within your email campaigns, but typically we suggest that the general rule of thumb is to ensure that your email campaigns do not exceed more than three scrolls. If you need to scroll more than three times in the newsletter then maybe it will be best to reduce some of the content. In our previous Legacy editor there is a limit of 100 blocks that you could insert within the editor, but there is no known limit for our current editor. I hope this helps. Let us know if you need assistance with anything else.
