Why are confirmation emails sent from ReferralHero?
When your users register on your campaign, we send them a confirmation email to verify their email address and prevent frauds.
Email confirmation is the only way to ensure referrals are legit and hence count towards the ranking.
Without it, someone could just refer themselves forever without the need to verify those emails, basically gaming the system.
When your users click on the link to verify their email address, the verification process happens on our servers and the only way to make sure these emails are sent is to send them ourselves.
It's the same reason why when you use email platforms such as MailChimp or MailJet you can't send confirmation emails yourself.
