Bypass all data limits that internet providers have on their outbound e-mail service.

SMTP service from MX-Relay is a reliable, powerful, easy-to-use service that maximizes the delivery ratio of all your marketing and transactional e-mails.

Why use a professional SMTP service?

It is important to follow the rules of the mail server, to prevent messages from ending up in spam folders or even being completely deleted by mail servers. Mail servers handle e-mails in different ways, based on the reputation of SMTP servers, white and black lists. SMTP servers offered by standard internet providers are not always reliable; they use random IP addresses and every now and then these IPs are blacklisted, which causes problems if you want to send e-mails. The worst thing is that you are not aware of these problems. When you send your e-mails, you will never know whether they have actually arrived.

The SMTP service from MX-Relay ensures that you can enjoy higher delivery rates.

If your server is not known to be reliable, almost all standard mail servers will delay your messages. In the best case, your e-mails will go to a gray-list or spam filter and in the worst case the messages will be rejected. These mail servers, such as hotmail, gmail, comcast and many others, have very strict rules because of the spam behavior of their users. As a result, it often happens that normal messages end up in spam folders.

By using the MX-Relay SMTP Service, your e-mails are considered reliable by all mail servers, which increases your delivery ratio. MX-Relay therefore provides a reliable and cost-effective SMTP service. We ensure that your e-mails are sent in a professional manner. This means that all mail servers recognize your messages as secure, so that the messages are always delivered.
