By default, our system resizes large images down to 800 pixels high or wide (whichever is first) and adjusts the quality to 70%. However, this can be disabled if required.
As per email design best practices, using large images in emails (or creating an image-only email) is not recommended - as they increase the size of the email and may cause it to land in the spam folder if the message contains little to no non-image text. Furthermore, users with screen-reader software, a vision impairment or those who use a smart assistant (think Siri, Google Assistant, etc) to read emails out aloud will ignore your email.
