On your site (https://reacher.email) it shows "Open-Source" next to the MIT logo. To any reasonable person, that means "it's licensed under the MIT license". Instead, it's licensed under the AGPL. It would be good if you changed it to remove the implication that it was MIT licensed.
Good catch; the author (amaury) is using my service Saasify (https://saasify.sh) to auto-generate the entire SaaS website so this was just an oversight.
I don't even think the OSI classifies AGPL as an Open Source license, does it. Open Source is Free Software, but that's because it can be relicensed to anything as long as its attribution requirements are held to. Free Software licenses are restrictive (to preserve the access of the user to the software they use.)
