Automatic subscription to newsletters and subscription confirmations (Python)

Write "Create a Python web application based on Flask using Bootstrap similar to https://adminlte.io/."

1. An API with URLs (700-3000 URLs) will be provided, to which subscriptions need to be made; the email for the subscription can be any for testing, but it should be Gmail.

2. In addition to making the subscription, it is necessary to automatically confirm the subscription via email.

3. The frontend should have a field for entering the email address so that it can be changed.

4. The frontend should have a field for entering the API, which can be changed.

5. The frontend should provide a report in RSS format, with the following columns:

a) URL from the API

b) whether the subscription was made or not

c) whether the subscription confirmation was made or not.

d) whether there is an email from the store confirming the subscription.

6. On the frontend, after all subscriptions have been made, there should be a summary:

the number of stores in the API

the number of stores to which subscriptions were made

the number of stores for which subscription confirmation was made

the number of stores that sent subscription confirmation emails

In your response to the task, you are required to indicate the time to process 500 URLs; if necessary, you should implement multithreading.
