I had to refund for 2 reasons:

1. We entered (imported with cvs) incorrectly more than 50 customers in the database and there was no possibility to delete them all together at once. In order to delete them we had to perform the action one by one, on average 2-3+ minutes per customer.

2. When sending an email through Cubicl we found a message under our signature that was advertising Cubucl.

Otherwise the software is easy and intuitive to use. They have really fast support!
