I purchased this, not realising that a 'sync' was an individual contact record. So, just to be clear, this deal only lets you work with 2500 contact records, which is far too few to be effective. Getting additional contacts requires a rapid escalation in costs. I would have preferred a greater number of contacts (say 12,000), and less frequent synch'ing. As such, I feel the current Appsumo deal is not workable and I requested a refund.
