Email validation & warm-up for free

Too many false positives and negatives!

As I have been doing email marketing for a very long time, this deal made me excited as it provides a lot of credits at a reasonable price. I believe in testing and verifying the output results before trusting anything for my business. So I have started doing many tests. But unfortunately, the results made me disappointed. My findings are below and I believe everyone should be aware of them before making their decisions.

1. They cannot detect catch-all servers in most cases. They are marking almost all the catch-all emails as valid, which is very dangerous. I have tested this with multiple known and tested catch-all email addresses.

2. Too aggressive spamtrap detection and full of false positives. They even marked one of my valid email addresses as spamtrap! Then I tried verifying a list of around 200 emails of my customers who actively communicated with me within the last month. But their system detected 22 of them as spamtraps (which is totally false).

3. They cannot verify Microsoft emails properly. I uploaded 1000 Outlook emails and they could only verify 8 of them. The rest of them were unknown. So the success rate for the Microsoft emails is like 0.8% for me.

4. They mark almost all Yahoo addresses as valid. So you will get a ton of bounces from Yahoo emails. I can understand verifying Yahoo emails can be hard. But marking almost all emails as valid is not acceptable.

5. They cannot detect temporary emails from most of the top providers (from the Google search).

6. Some other issues I also detected, but I will ignore them for now considering that a new product (i.e. cannot process larger email list with multiple columns, no progress tracking which is very frustrating, etc.).

On the other hand, there are many good sides as well. Their support is good and answers the questions quickly. Their verification speed is also good and displays the verification process (for single email especially) in a very unique way, which I liked a lot. They are also offering a good amount of credits at a reasonable price.

I hope this will help the other buyers to make their calculated decisions, as the impact of such a product can have a big impact on their business (good or bad). I think the mentioned points will also help the developers to identify the issues easily. I will review it again in the future and will update my review if anything changes. Enjoy the email marketing!
