During the risk-free trial, you'll have access to the full suite of features that ReferralCandy offers, which includes sending out emails to others regarding your referral program.
Email deliverability is very important to us as it allows us to run your referral programs effectively. Unfortunately, we've had instances in the past where customers have mis-used the email sending feature, compromising the email deliverability for everyone else on the platform.
As such, we've had to make adding your payment details a requirement, to protect our customers from having this sort of malicious behavior affect their referral program performance.
Thank you very much for your understanding in this matter.
Finally, if you cancel anytime within the risk-free trial period of 30 days, you will not be charged.
