30.17 Message type filter

30.17.1 Overview

The message type filter automatically detects which kind of mail is involved: regular email, newsletter, automatic reply, bounce notification, calendar invitation, read or meeting response, or spam. It is the solution for profiles that should target only certain mail types or exclude typical “noise mails”.


30.17.2 Available types

Type Matches
Normal Standard email without special marking
Read receipt Confirmation that the recipient has read the mail
Delivery receipt / Bounce Delivery or non-delivery notification from the mail server
Auto-reply Out-of-office or automatic reply
Calendar invitation Invitation to a meeting
Meeting response Response to a calendar invitation (accept, decline, update)
Newsletter Bulk mail with unsubscribe notice
Spam Marked as spam by the mail server

30.17.3 Operators

Operator Description
equals Message is exactly of the specified type
does not equal Message is not of the specified type

30.17.4 Detection

The program inspects typical message characteristics (e.g. content type, mail server tags, multilingual subject line heuristics for out-of-office replies). If no special type is detected, the message counts as Normal. Spam overrides newsletter and auto-reply, so that a newsletter mail flagged as spam appears under “Spam”.


30.17.5 Use case

Automatically move newsletters to archive

Message type equals Newsletter

Combined with the task Move email into a “Newsletter” folder, this reduces inbox volume without deleting newsletters.


30.17.6 Tip

  • Detection is not 100 % - mail servers handle markings differently. For misclassifications, the Result preview (see chapter 8.11) shows how the program has classified a sample message
