Disappointing pricing, documentation, and customer service
The documentation for the product is almost non-existent. If it were more clear, I would have learned ahead of time that the "$50 Minimum" doesn't involve any sort of credit system. If you spend less than $50, you get charged $50 regardless of how many emails you are validating. So uploading a list of 2,500 contacts doubled my cost under that pricing scheme. Given that Marketing Pro includes just 2,000 marketing contacts, validating marketing contacts will cost double or more in most instances. When I reached out to ask about the details of the pricing structure, I was met with lukewarm customer service and after a couple attempts to resolve my problem was told that I would need to purchase credits which can only be purchased by emailing the company and telling them how many credits you would like to purchase. This is, to me, severely inefficient. I don't recommend this for anyone outside of Enterprise users and even then the customer service would likely be lacking based on my experience.
Validation of contact lists for SMBs. Typically 2-3 thousand, but sometimes smaller batches of a few hundred at a time. Was considering using it for the "Enhancement" portion until my 1-star experience with the validation service.
