Integration details
Description
Work your SuperMailOS business email from a conversation. - Catch up fast: see which unread conversations need a reply, which need a look and which can wait. - Find anything: search across your mailboxes by sender, subject, label, attachment and date, and open attachments such as invoices and spreadsheets. - Reply in your voice: replies are saved as drafts in SuperMailOS for you to review. Mail is sent only when you clearly ask. - Stay on top of follow-ups: see who owes you an answer and what you still owe others. - Keep the inbox tidy: mark read, archive, move and label conversations once you confirm. Who it's for: people and teams who use SuperMailOS for their company email. You need a SuperMailOS account. The connector acts as you and sees only the mailboxes you can open in SuperMailOS; workspace owners and admins can reach every mailbox in their workspace. You choose the permissions when you connect: read mail; organize mail and save drafts; send mail. Leave out sending and it can only save drafts. Limitations: it can't permanently delete mail, change settings, manage people or domains, or send attachments, and a brand-new email (as opposed to a reply) can't be saved as a draft. Emails are treated as content written by other people, never as instructions.
