FAQ

Questions about Slack + Gmail.

How do I post a Gmail to Slack?
Gmail Email Received with label "@slack" → Slack Send Message in a chosen channel with sender, subject, snippet, and a Gmail link. Useful for shared support inboxes or VIP-customer mail.
Can I send a Gmail from a Slack slash command?
Yes. Slack Slash Command (/email) → parse target email and message → Gmail Send Email. Useful for community moderators or ops handling outbound mail without leaving Slack.
How do I post an AI-summarized inbox to Slack daily?
Scheduled 8am: Gmail List Messages from last 24h → Claude/OpenAI summarize as "what changed in your inbox" → Slack Send DM with the digest. Morning inbox-overview without scrolling.
Can Slack reactions trigger Gmail responses?
Yes. Post Gmail to Slack with reaction buttons. Reaction → look up the original Gmail message → Gmail Send Reply with a templated response based on which reaction was used.
How do I avoid Slack-channel noise from a busy inbox?
Filter Gmail triggers tightly (specific labels, specific senders, AI-classified importance). Aggregate via hourly or daily digests instead of per-email posts.
