Need STRAPI expert to send email with the Sendgrid plugin

I have 4 models on STRAPI:
- user/shop {username, email, pwd...}
- distributionCenter {name, arrUserID(array of User id) }
- product {name, description}
-shipment {title, dateShipped, productID, distributionCenterID}

A user (or store) has many distributionCenters. A distributionCenter has many shipments. A shipment has one product.

SCOPE
*********
Use the STRAPI plugin, sendgrid, to send email every week to each user to inform them of their shipments of each distribution Center of the last week.
For example for userA, the email should be as follow:
"Hello userA,
In the last week, distribution center A sent 5 products A and 7 products B. Distribution center B sent 3 products C and distribution center C sent 2 products B.
"
