MarsSeed [1] filed a deletion request for python-mailjet [2]: Orphaned package, some Python wrapper for a specific non-mainstream email service provider. Last release on PyPI is from 2020 and is only tested with up to Python 3.6. The code is not really developed much nowadays, as seen on devs' GitHub. I think it's better to delete this quite abandoned library package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-mailjet/
