I have searched everywhere and have not found an answer to this.

Site running WP/Woo.

Very simply if a customer purchases we want to add them to Campaigns.

Also, if a customer registers and doesn't purchase we want to do the same.

Is there a connector (free or paid) out there that will handle this?

I know I could go from WP -> Zoho CRM -> Zoho Campaigns

I have reasons for not wanting to do it that way.

Any and all help much appreciated.
