Yeah, yeah we've all seen the terrible Indian emails promoting mashed together Fiverr gigs. But today a light went off in my head, and here's what I did. Talk to them, yes, pretend like you're looking for White Label SEO services. Build trust here, shouldn't have any problems here. Ask them about what they offer in their packages, backlinks, onsite all etc. Ask to see portfolio, they'll provide some, I got a list of 10 clients. I would then contact the site owners, informing them of the problems(which they will have) on their site. More relationship building here. I offered to 'detox' their backlink profile, and from the 4 people who responded, 1 of them signed. Now they are in their first month with me. So yeah, a bit lengthy, but next time you see someone from India emailing you - see it as an opportunity! Srs.
