We need somebody who can create a Mailchimp API, with a backend for us to input table of values. Each value can only be used once, so that when a user submit a newsletter subscription form, an automatic response will be generated. The automatic response will contain a value that is pulling from a source, once this value is sent out once, it cannot be used again.
*note, there must a way for us to control what the values are, preferably through uploading an excel sheet or something. The emails must also be synchronized into our mailchimp account, so we have a record of who received which unique value.
Userflow: Users visit a landing page (we will provide hosting)-> fills out a form (first name, last name, email address, captcha) -> receives automatic response with unique value, along with other pre-designed content ->
See userflow diagram below:
