Hi @adeelraza_786,
Greetins and thanks for your question! Were you asking about opting in to a mailing list?
If so, you could try using Remote Pings to automatically subscribe users to a mailing list. The following has some initial details that could help:

And more specifics here surrounding MailChimp as a solution:

Is that along the lines of what you were asking about?
Please feel free to let me know if I’ve misunderstood or if you have questions. 🙂
Thanks,
David
Hi there @adeelraza_786,
We haven’t heard from you in awhile, so I just wanted to check in to make sure all was good.
This thread was marked resolved, but if you still need help, please just respond and open it back up. We can then take it from there. 🙂
Hope you have a fantastic day!
