You may earn free months of SessionLab Pro subscription if you invite new people to join SessionLab.
If you are on an individual (Basic or Pro) SessionLab subscription, you are rewarded with a free month of SessionLab Pro for every 3 people signing up from the invitations you create at your ‘Invitations’ page in SessionLab
Please note that session collaboration invitations – when you directly invite collaborators to your sessions from a session you are working on – do not count towards your reward count.
If you are on the free Basic version of SessionLab, when you reach 3 invitations redeemed, you automatically get a 30-day Pro trial period credited on your account.
If you are on a paid Pro subscription, your reward is applied from the start of your next billing cycle. (If you are on a monthly subscription, then from the next month, if you are on an annual subscription, then from the next year.)
