Can incoming emails be filtered & ignored?
It is possible to define individual inbox import conditions which can automatically filter out certain e-mails. You can define, for example, a condition to only accept e-mails which have the word 'XYZ' in the subject line.
This setting can be found in the Inbox Settings tab, under Email Reception:
You can then add multiple conditions if you like that will be linked with a boolean AND, meaning all arguments must match in order for the email to pass through to your inbox.
When using the 'contains any of the following keywords' filter, the delimiter is a comma followed by a space - each string is case-sensitive.
Emails will show up in your inbox only if all the conditions match.
