Customer Reviews
Solid service for cold email
I signed up for their SMTP for Cold Email service and it's been pretty reliable. The ordering process with Bitcoin was smooth, which was a big plus for me. Integration with my existing setup was a breeze thanks to their docs. I also tried their Email API and it worked as expected. Deliverability has been consistent, which is key for cold outreach. No issues with support either, had a quick question about dedicated IPs and they got back to me fast.
Simple Anonymous SMTP purchase
Bought the Anonymous SMTP service. Paid with crypto. No KYC which was important. It works. Good for what I need.
Easy setup, good for WordPress
I needed an SMTP for my WordPress site and tried KingSMTP. It was actually pretty straightforward to get it set up, even for me who isn't super techy. Sent a few test emails and they went through without a hitch. Happy with it so far.
