Frequently Asked Questions

Find answers to some frequently asked questions about SMTP

What is mailRelay?

mailRelay is a managed SMTP based email service to provide fast and reliable outbound delivery of emails, developed and supported by our in-house team of email experts.

Is mailRelay compatible with Azure?

mailRelay is used by many of our clients to send emails from their Azure hosted services and virtual machines. Alternate port numbers provide reliable access via TCP/587 or TCP/2525 where port TCP/25 may be blocked.

Is a dedicated IP better than a shared IP pool?

Adding a dedicated IP to the mailRelay service can be beneficial if you have specific security requirements or send high volumes of email. However, if you send modest volumes of email a dedicated IP can hamper delivery by virtue of having a lack of track record for sending.

How long does the service take to provision?

As part of our strict antispam policy we review all mailRelay orders to prevent misuse so activation is up to 1 working day, though typically it is within a few working hours.

Do you have to host our mailboxes?

No, as mailRelay compliments your existing mail flow so can work in tandem with your current mailbox hosting. Many clients use mailRelay with domains hosted within Microsoft 365 or on-premise Exchange servers.

Why should I use mailRelay?

By harnessing our reputation for sending 'good' email you will achieve high delivery rates to your clients, whilst avoiding the need to manage a mail infrastructure to send email. 

30-Day Money-Back Guarantee

If you are not happy with mailRelay for whatever reason, we’ll refund your payment. No hassle, no risk.
