Personally, I really like sending emails from Dev. At the moment and for the next few months, I expect that we will only have 1 user in our database, so the risk is low, but know this does break best practices. The case i would make it that when i develop, i spend a lot of time also looking at the interface and my inbox to make sure everything is working. More so, when building emails, they are absolutely horrible to style. I must have sent about 200 emails to my self while styling the templates.
Usually though, I re-enable them locally, then diable them before pushing.
