What Ham Email is built on, and who to thank for it.
Ham Email is assembled from open-source work by a great many people. Each component below is used under its own license, and those licenses continue to apply.
Gravatar supplies sender photos when you have them switched on. QSL World provides the callsign address, the free tier of the writing assistant and callsign lookups. Your mail provider and your AI provider, if you add a key, are your own. Service names and logos belong to their owners and are used to identify those services, not to imply any endorsement.
Most of all, Ham Email exists because of the people who keep the bands alive and who still write to each other afterwards. This one is for you.
