Workgroup module availability and license

[kstabel]

Hello OpenCloud community,

I have a question about the upcoming opencloud collaboration suite (email, etc).
There is mention about it here: https://opencloud.eu/en/news/opencloud-calendar-and-contact-management-available-community

I would like to know if the email client will be available as open source.
The article mentions business users. Will this be a paid license?

Email and a few other small things are currently keeping me on nextcloud. I could work around it with external site links, etc, but integration would be nice.

Thank you for your time.

This must be a difficult question i guess?
