Email marked Slack messages with Gmail

Send a Gmail email when someone marks a Slack message with [Email]. Use this to pass selected channel updates to reviewers who follow work from their inbox. Connect Slack, select source channels through Browse, connect Gmail and enter a fixed recipient address. The [Email] keyword is prefilled, matched anywhere without case sensitivity, and bot messages are ignored. Each plain-text email contains the complete message, author ID, channel ID, original Slack timestamp and source channel link. Includes its own fictional English Hannover handoff example with German Unicode. Add FastHook to the source channel before activation. Leaving Channels empty watches every channel accessible to the Slack connection; matching human thread replies also send email. Only new matching messages are processed, not historical messages, edits or deletions. Mentions and Slack formatting remain literal source text. Files, attachments and surrounding thread history are not copied. This creates an email notification, not a Slack reply or synchronized conversation. Email recipients can read the copied message; opening the source channel still requires Slack access. Emails are sent from the connected Gmail account and appear in Sent. No HTML, Cc or Bcc is configured. Gmail limits apply and manual reruns or ambiguous provider retries can resend a message. Use your own email address for the first test.

Send Slack alerts for matching Gmail emails

Stay informed about priority inbox messages without forwarding whole emails. New Gmail messages matching the prefilled search subject:"[Alert]" produce a plain-text Slack alert with the subject, sender, received date and Gmail conversation link. Connect Gmail and Slack, review the search query and choose a channel where the FastHook bot can post. Includes its own fictional English alert. Only newly received matching inbox messages are processed; this is not a historical import, label-change monitor or two-way sync. Email bodies and attachments are not forwarded. The Gmail link requires access to the same mailbox; select that Google account if you use multiple accounts. Subject and sender details are shared with everyone in the selected channel. Each new matching message produces one alert, including replies that still match the search.
