Most people try to get clients through email, DMs, or contact forms.
A less obvious angle is domain inquiry outreach.
Some domains registered through Cloudflare let you send a message through a domain inquiry form and Cloudflare then forwards that message to the domain owner or whoever manages it.
So the play is simple: find a company website, check if their domain has that inquiry path available, and use it to send a short, relevant pitch.
That makes it interesting because you're not fighting in the same crowded inbox everyone else is spamming. You're using a channel tied directly to the company's domain.
Everyone copies cold email but very few people look for alternative paths to the same decision-maker.
That's usually where the edge is.
