Hello!
We at Sendent build integrations that connect your favorite mail clients with Nextcloud. Today we’re happy to share that Sendent for Mac Mail is now available for beta testing!
If you’re a dedicated Apple Mail user on macOS, you can now upload files directly to your Nextcloud server without leaving your inbox. Instead of bulky attachments, Sendent uploads your files to Nextcloud while sending and conveniently shares your files with the recipients.
A fair heads-up; Apple’s Mail extension platform is (far) more restrictive than what we’re used to with Outlook, so this version is leaner on features. The good news: after the beta period, Sendent for Mac Mail will remain free with its current feature set.
Join the beta via TestFlight:
