Repeated executions occur when using the email trigger | Community

​@Padmakumar  Hello , I’ve already looked at it but doesn’t help me

Ok. 

Before doing any real work:

1. Extract a unique identifier from the email (preferably Internet Message-ID; fall back to a hash of From + Subject + ReceivedDate + Size).
2. Check a local/central registry (CSV/Excel/DB/table) of processed IDs.
3. If already seen → skip. Else → add it → continue.

Best practice:

Moving to a processed folder is the most reliable way to prevent the next poll from seeing the same message. So your trigger filter excludes processed items.
