Yes, but they collect much fewer emails, for example, if a CPA network asks for an email on a sweepstakes landing pageYou can promote survey/email submit offers – most affiliate/CPA networks have them.
I'm the owner of websites, so it's possible. I never thought about this monetization typeYou can collect phone numbers data as well ?
the monetization tool they probably mean is collecting emails for an email list you can market offers toI have some websites and I know one of the monetization tools is collecting emails.
Maybe it's possible to add an email fill field to a 3rd party who works with emails and sell it directly from my websites?
