Features of our SMTP service

Dedicated IP addresses

Use a dedicated IP address to increase your sender reputation and avoid blacklisting of your IP due to someone else’s actions.

SPF and DKIM records

Show that it’s really your own company and domain sending the message, and minimize the amount of messages that are marked spam by using the special cryptographic signatures SPF and DKIM.

Servers you can trust

For each mailing list, you can discover the amount of messages sent out, the number of conversions made and links clicked, and many other details.
