You can technically link emails to organizations, you just have to send the email through the email field in the organization's contact page. This is a workaround I suppose, though I see what you mean. replying to an email it is not possible to link it directly to an organization.
i am new to Pipedrive, and I thought it was something I did not understand. But I see now its not a field in the contact card for organizations for email. That is very strange for me. Could anyone explain why it is so?
Upvoting this - Pipedrive team, we need ability to tie emails to leads/deals/organizations because we have general conversations with organization leadership in the hope of a potential lead / deal but we cannot track those organization level emails before we have a lead or deal meaning the only work around I see is to create shadow organization leads or deals called "Organization General" so that we can track emails
