With Digest by Zapier, you can compile data from Zap triggers or actions in a single batch that can be sent at a regular interval to a Zap action. This means that instead of the actions in a Zap running every time the trigger or action event occurs, the Zap will receive the data and run in bulk at a given interval, such as every day or every week. Digests can be used with one or multiple Zaps.
You have Zaps that receive leads and assign them to different salespeople. You can use a Digest by Zapier step to receive an email every Friday that contains all the leads that came in that week. This cuts down on the number of email notifications you receive while still allowing you to keep track of your leads on a weekly basis.
