Run a quick check on each sent subject
Apply a small, repeatable subject check as part of your send flow and review the command result.
Trigger
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
Action
Run Terminal Command
Run a command in the terminal and returns the stdout, stderr, and error code. use /home/user folder to write/read files.
Why this helps
Small subject-line checks are easy to skip when sending quickly, even when a consistent convention matters.
- Run a repeatable command after a send event.
- Check only rules you specify in the instruction.
- See command output and error details in the run.
Setup
Build it in a few focused steps.
- 1Connect Gmail and Codeinterpreter once in the Notis portal.
- 2Create an automation for sent subject checks.
- 3Describe in one instruction the subject rules to check and the command output to return.
- 4Choose the Email Sent trigger and a report destination.
- 5Test with one real sent email and confirm the check behaves as expected.
