Digest delivery is a way to bundle many messages together into one email.
Some users prefer digest delivery for higher traffic lists since they will receive fewer emails.
Digests can be delivered once per day (if there were any posted messages), or whenever the bundle is bigger than a specified limit.
Note: All digests are automatically sent at noon (UTC) each day. *
Digests are labeled with a Volume number (starting at 1) and an Issue number (also starting at 1).
The subject line of the emailed digest contains the label. For example, the subject line of a list's first digest will look like:
Subject: [NameOfYourList] Digest Volume 1, Issue 1
When a list's digest volume is set to 'Daily', a new Volume number is created each day. For example:
Monday -- Subject: [NameOfYourList] Digest Volume 1, Issue 1 Tuesday -- Subject: [NameOfYourList] Digest Volume 2, Issue 1 Wednesday -- Subject: [NameOfYourList] Digest Volume 3, Issue 1 ...
If the setting were set to 'Weekly' then all the digests of the first week would be Volume 1. The second week's digests would all be Volume 2, and so on. The Issue number would be incremented each day.
To illustrate the Weekly setting:
Week 1 Monday -- Subject: [NameOfYourList] Digest Volume 1, Issue 1 Week 1 Tuesday -- Subject: [NameOfYourList] Digest Volume 1, Issue 2 Week 1 Wednesday -- Subject: [NameOfYourList] Digest Volume 1, Issue 3 ... Week 2 Monday -- Subject: [NameOfYourList] Digest Volume 2, Issue 1 Week 2 Tuesday -- Subject: [NameOfYourList] Digest Volume 2, Issue 2 Week 2 Wednesday -- Subject: [NameOfYourList] Digest Volume 2, Issue 3 ...
The same pattern applies to Monthly, Quarterly, and Yearly.
Remember: in each case, the digest is still sent at noon each day.
Administrators can also set a 'size threshold' so that the digest is sent as soon as it reaches a specified size (measured in kB). Doing so would see multiple issues in a day.
You may want your list to send a digest only once a week, once a month, or occasionally.
Set the following digest options permanently:
Then, when you want to send your digest, set the following option and submit:
Note: Overriding the daily sending of digests has to be done by the list administrator. It cannot be automated.
