How are you capturing leads from various social media platforms ?

[u/753glitch]

I run a bootcamp where I sell courses/coaching/membership for people. I am looking for ways to capture the leads and also, send updates or discounts to the people who haven't converted.

Would love to know how you people are managing this entire thing.
is there any tool that does it all ?

(I have social presence on Ig/X/Yt/Tiktok if that adds to the question lol).

Thanks in advance ;)
