Why switch to Maileroo?

We might be new, but we know what we're doing. We got about a decade of experience in software development and unlike other providers, we run our own infrastructure. That means we don't have to pay a third party like Amazon SES or SendGrid to do the heavy lifting for us. We've got our own servers, our own network, our own IP addresses, and our own team of experts to make sure everything runs smoothly. That's how we can afford to offer a free SMTP service. We're not cutting corners, we're just cutting out the middleman.
