People should be able to connect their put their email into Gerev and any incoming emails will be added to their data.

Slack : 10 million users
Notion : 10 million users
Confluence : 25 million users
Email : 4.4 BILLION users

Ideally, this should be able to access emails sent before joining Gerev too. I think this could be done through the user's google account. That might trigger security concerns in some people, but, if the end product is good enough people will use it despite security concerns. We can just have a subheading that says.

your data is safe

(Also we should actually have good enough security do avoid a data leak)
