What is Autovacuum?
In the context of 
email marketing, autovacuum refers to an automated process that helps maintain the health and performance of your email database. It involves 
cleaning and 
optimizing your email list by removing inactive, invalid, or unengaged contacts.
    Deliverability: A clean list ensures that your emails reach the 
inboxes of your active and engaged subscribers.

reputation with ISPs (Internet Service Providers).    
Cost Efficiency: Most 
email service providers charge based on the number of subscribers. Removing unengaged users can save costs.
     Data Collection: Collecting engagement metrics such as open rates, click-through rates, and bounce rates.
    Analysis: Analyzing this data to identify inactive or unengaged subscribers.
    Action: Removing or segmenting these contacts for re-engagement campaigns or permanent deletion.
When Should You Use Autovacuum?
It is advisable to run autovacuum processes periodically, depending on the size and activity level of your email list. For most businesses, a quarterly or bi-annual autovacuum process is sufficient. However, if you notice a significant drop in 
engagement metrics, it might be time to run an autovacuum.
