Mailing platform. No spam.

The system must allow me to schedule the email with all the banners that the user will recive. The system must use the sendgrid api. The system should have the option of merge tags, so if i type for example |Name| in the subject line the user will recive a personalize email with his name. The system must integrate google analytics or sendgrid analytics so i can know the bounce and open rate and the time by user, categories, companies, town and city. There should be an option for the user to cancel his suscription and all his information should be erase from the system. If the user select a lot of categories and the email will contain more than 8 banners for example, the rest of the banners that the user choose to recive will be send in another email for later on the same day. Create an admin section where i create the profile of companies that send emails with the following information : country, city, town , logo , phone number, website, Facebook, twitter , instagram , youtube , Foursquare, whatsapp , address . Basically a simple form for companies. I want to integrate this system in to my website, so there is no web design besides the login screen, and the user panel where he choose the categories. My idea for the banners is to create a html template with all the banners of all the categories, and put in the id of each banner, a kind of "code" so the system knows that that banner corresponds to a specific categorie and the city or town. For example id="City1Bank"
