Do you want to become an expert in email deliverability, DNS, bounces, white listing, DKIM, SPF?
Or do you want to sell your product?
It boils down to that. Spend your time doing what you are GREAT at and what you WANT to do. Are you great at email deliverability? Do you want to spend your time becoming an expert on that? Probably not.
I know how to change the oil in my car. I know how to mow my lawn. I know how to clean toilets. I don't do any of those things because they are a huge waste of my time that is better spent elsewhere. Same thing goes here.
