Hey {first_name},
 

We tried to reach you the other day and have not heard back. You currently are on a report we receive indicating that your policy with us has an issue. Typically it is a coverage falling off or a failed payment, but we need to catch up so you do not lose coverages or get dropped. Please call the office ASAP at (OFFICE NUMBER) to resolve.

Best,
