A/B testing parts of an EMAIL (eg. a button or image)

My idea is: A/B testing for parts of email (not for the entire Email).

I think these groups of people would benefit from this idea:

Enterprise customers coming from other marketing automation platforms where this feature exists.

Why I think they would benefit from this idea: Feature parity - Easy migration to Mautic.

Are you willing to work on this idea?: Potentially yes.

What skills and resources do you need to explore this further?
No clue on if this is hard to buid, achievable or what the needed work would be.
