Green-Goo kills black mould
Basically you get to only create one campaign and get locked into the promo of that campaign. If you try to create a new campaign all your previous customers will be directed to the new campaign. Campaigns can also only be sent a maximum 4 days after the customer visits. Once you use this app you are stuck with legacy bugs as customers are led to invalid voucher pages if you decide to not go ahead with the app.
