@valerycolong This mail adapter has been designed specifically to allow adding any 3rd party mail providers like Sendgrid. This should not require any changes in the adapter code, other than in the file src/ApiPayloadConverter.js. With the changes in this PR we cannot accept to merge it. If you want to refactor and only make the changes in the file mentioned earlier (and the README for documentation), then we'll be happy to review. The benefit of submitting a PR for Sendgrid to our repository would be that you don't have to maintain a custom fork, which, given the vast changes in this PR, could become quite complex quite quickly when we'll make changes in the base repository in the future.
