How does the Refer a Colleague program work?

If you like Seraf and want to refer our service to colleagues, both you and your colleagues will receive 30 days free! Just provide them with the 5-character Promo Code found in the Account Management section of your account. Once your colleagues sign up using your referral code, they will receive 30 days free, and you will too! Seraf will automatically send you an email confirming that your subscription has been extended by 30 days for each new subscriber.
