Amazing price and result quality for an email verifier. I have been using it for months though their API. It was very easy to integrate with n8n thanks to their online customer video tutorial. 💪🏻

I recently tried MailTester Ninja to improve my email verification process, but my experience was somewhat disappointing.
On the positive side, the interface is user-friendly and easy to navigate. I appreciated the straightforward setup, which made it simple to get started. However, I encountered several issues with accuracy. Some emails that were flagged as invalid turned out to be legitimate, while others were confirmed as valid but bounced later. This inconsistency really affected my trust in the service.
Additionally, the customer support response was slower than I expected, which was frustrating when I needed assistance. Overall, while MailTester Ninja has potential, it needs improvements in accuracy and customer support for me to fully recommend it.
