Took my money and gave nothing

What are the best aspects of this product?

free tier was good up until you give the business payment.

What aspects are problematic or could work better?

Tried to use this service, so I uploaded a campaign and purchased the 10k user tier. Support needed to approve the 10k list first, which is ok. So, they did not approve and told me I could not send a campaign to a list of users because some of them were not authenticated. Ok, so I asked for a refund as no campaign was actually sent. At that point, they argued it was against their policy to provide a refund because my list was no good and it goes against their policy to have a poor list. So, it seems that the company is selective about how many emails you can send even if you pay for a certain number, and they will not refund even if you never send an actual campaign. Terrible support and policy that stole my money and gave nothing back.
