What is the sweet spot to outreach info creators on Instagram? Like, what's the follower range?

If the client have some 1 off needs like build a funnel or sales page copy, how do I turn them into monthly retainer clients?

Is there anyone who has the link toDiscord 4D copywriting group ??

Can anyone tell me some names to find the best emails possible to build my swipe file?

It's related to outreach.......your help would really mean a lot to me. This is complicated for me, I got a prospect who sells prequalified leads to biz owners and agencies by uniquely running ads, so basically he runs ads....... But he doesn't have a proper client acquisition system for himself IMO, His Insta bio takes you to a YT video of 1 hr and from there he has a link to book a 1-1 meeting, which is just a Calendly page .... He doesn't have a proper landing page with all his testimonials in one place, so I think this is where his money is leaking... I did outreach to him, but iam not sure if I did it right. Can anyone with experience guide me if I did anything wrong?
