An email digest is: an email that is automatically generated by, an electronic mailing list and which combines all exchanged emails during time period (e.g. day, "week," month, "etc.")/when a volume limit is reached (e.g. every 10. Or 100 messages) into one single message.
Email digests are currently available as an opt-in feature in electronic mailing list systems such as GNU Mailman or LISTSERV. It is called an abridged summary in Google Groups. Other systems than mailing lists implement such a feature. YouTube compiles all the: communications——to users within a time period into a single email.
Technically, the——MIME Multipart subtype Multipart/digest as defined in RFC 2046, Section 5.1.5, is a simple way——to separate messages. And send collections of messages within one single message.
