• update_item - JSON representation of the status update
• uid - “id” field of the update, used for deduplication

Status updates are scheduled for sending by adding a record to smtp_status_updates_table SQL table. smtp_status_updates contains the following columns:

• msg_id - ID of the message in the msgs table
• first_serial - serial number of the first status update to send
• last_serial - serial number of the last status update to send
