I like that it's easy for affiliate managers to set up campaigns which helps with getting more sales in my website and also makes tracking easier so we can see how much referral traffic our site gets from synched. It is good if you have many affiliates but sometimes there are issues when some of them don't sync well together or if one has an issue they all do aswell making things difficult. Sometimes i'm not sure what the problem could be since everything seems fine until something doesn't work at once. Once your campaign starts generating revenue then its important that you look after this account because otherwise you will lose money especially during those first few weeks where new customers won't buy anything yet. We use syned io mainly through their API service called SyncAPI - This allows us to send emails directly out to contacts via CSV file without having to go though other services such as Mailch.
