From Deltachat matrix group:
- r10s/dc: you can export your secret keys at "Settings/Advanced/Manage Keys" and try to import them to Claws mail (i am not using Claws, but that way it works for me on Thunderbird)

That's it! Thanks! Claws mail is not the easier mail client, but it's very powerful and I can do it setting and using an action:

GnuPG/Import Key From Mail: gpg --import %p
Note: to use an action, first you have to create this action in Claws mail, and then you have it available in an Action's submenu
