Okay, that worked , I successfully embedded the form from the mailchimp and when i submit the form ( i.e ) click on subscribe button ( image preview : https://imgur.com/vzv2csd.png) and it opens the new tab and say the subscriptin has been confirmed..(https://imgur.com/YJd8PXn.png).
and when i click on continue to website it redirects to unkown mess link (https://imgur.com/aioUspn.png)…

Moreover, i dont want my users go out of my website, when i click on the subscribe button it should show subscription confirmed… and it should not redirect anywhere.
How do i achieve that..
