Looking to migrate from Front to Spark Teams

Hey there!

Like the title says, I'm looking into the possibility of migrating my company's domain from Front into Spark Teams.

Front is super expensive and they will stop syncing email statuses (read/archived/etc) with Google, which means our Gmail accounts will be a mess.

The key feature we use in Front is the conversations inside emails, which you can also do with Spark Teams. However, I'm wondering how to migrate the history of conversations too.

In Front, you can ask for an export (but it doesn't include conversations from not shared inboxes). I guess we could get them via API.

Is there any "import" feature in Spark Teams? Or an API we could use to load them manually?

Thanks!
