1. Jelly has a way to follow conversations and get notifications about replies and comments. So everyone can follow the convos they care about via Jelly notification emails sent to their personal team email.
2. For teams on our higher tier Royal Jelly plan, we have an IMAP feature that can sync mail sent out of Jelly back into your Gmail. It says "Coming soon" on our price table, but it's a working feature in alpha right now, and we already have some customers using it. We'd be happy to help any team get that set up if they need.
Being able to try a service "risk free" seems really important. To start replying to emails in a new service and then lose them if it doesn't work out doesn't sound like a reasonable option.
We (Good Enough) would rather help an unhappy customer exit cleanly, than keep you stuck using software you don't like.
If this is the only thing stopping you from using the service, get in touch with us and hopefully we can reassure you about how committed we are to helping you leave Jelly with all your data intact, if it turns out to be the best thing for you.
