Your Mail Transfer Agent, hosted in Switzerland.
The MTA is the engine that moves your email across the network. Mailpro runs high-availability virtual MTAs in our own Geneva data center — so your campaigns route reliably and your data stays protected by Swiss law.
What is an MTA?
A Mail Transfer Agent is a mail server or mail exchanger — you might also hear it called an MX host or mail relay. It exchanges messages across the network between mail servers in a background process, traditionally over Port 25.
On the Mailpro platform we mainly send emails, mass emails and transactional automated emails. Behind the scenes, our MTAs handle the routing that gets each of those messages reliably to its destination.
Why route through Switzerland?
Your data is the real asset of your company — your customer database, your content, your product and patent information. And while an email is in transit, your MTA has access to it and can analyse its content. If your provider uses an unsafe cloud, that data is exposed. The safety of your data isn't only technical; it's also about a location that protects it by law.
