Recommendations: Lifecycle, do I store them or no?

I'm successfully creating recommendations using Elasticsearch.

How should I utilize the recommendations?

Should I store them, then send them out periodically?

If I sent (emailed) a recommendation to a user, should I delete it to make sure I don't send it again?

As you can read, I am getting into the details of the lifecycle of the recommendation.
Any suggestions are appreciated.
