I have a Gmail filter that applies a label ('OTPs') to certain incoming messages. They accumulate and I want to keep most for only a couple of days.
I can eliminate them manually by performing a search (e.g. 'older_than:2d label:OTPs -label:GST') and then deleting the results, but I want to automate this process using a filter.
The example below shows a highlighted message thread 'SMS Forwarder' that totals 21 individual messages of which only 7 would match my criteria for deletion, and the remaining 14 would be kept.
