I order optinmonster integration with sending subscription emails

Good day!

The matter is as follows. We have created a form in optinmonster (wordpress) with an e-mail to newsletter. We need that after entering the data (name, e-mail) the user receives

- an e-mail in which he has to confirm the subscription

- after confirming the subscription welcome e-mail informing that the user is on our list, and this must also include a button to unsubscribe.

OptinMonster can be connected with Mailchimp. However, it is not required. We especially care about the speed of execution of this order
