Send Emails Via Google Gmail or G Suite

Using HirePOS to send emails via your Gmail or G Suite account can be very beneficial, it will reduce the chances of emails going into Spam drastically, and sent emails will appear directly in your Gmail "Sent" box. However, there are often some additional steps that must be completed before it will work, which are noted in this article (for G Suite and Gmail) and in another article for Microsoft Office 365.

Although an SMTP setup with Gmail or Outlook can work effectively when setup properly, authentication and spam issues can still occur. To mitigate these issues, consider using our recommended email setup with

Configuring G Suite (Gmail) for SMTP Relay

As with Microsoft Office 365, Google's Gmail is not always ready 'out of the box' to work with HirePOS. There are often a series of configuration alterations and checks that should be considered when troubleshooting an HirePOS > Gmail SMTP connection.

This is best undertaken by your IT person, or someone with some technical understanding in configuring email services.

Please see the following article from google covering the checks required to ensure a seamless email experience.

Keep in mind, should this path become to difficult or time consuming, HirePOS also offers you the ability to:
- Easily authenticate HirePOS with your domain provider (allowing us to legitimately send messages on your behalf); and
- Make use of the virtually spam-proof, whilst setting the reply-to address to your own, so you can rest assured you will receive all reply emails as intended.

  2. Press the Edit cog link to the right of the From Address
  3. Select either Main Business Email or Other Business Email Address from the first set of options
    1. In the case of Other Business Email Address be sure to set an address that has "send as" permissions enabled for the Office 365 account you are planning to add. (by default, the only address you are able to send as will be the actual address of the account)
    Important: You will only be able to send from an address that has "send as" permissions in the Gmail account you are adding.
  4. Below the email address field on this screen, select the option Your SMTP Server
  5. Press the SMTP Settings button

It didn't work...

I got an error
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM ...
Often the result of attempting to send with a From address other than the one used for the SMTP connection. Could also be the result of a bad username and password.
An error mentioning "Timeout"
Usually the result of a bad username and password, or intermittent network issues.
An error mentioning "SSL" "TLS" or "STARTTLS"
It is possible you have entered an incorrect Port Number or SMTP server, or have not selected the SSL checkbox.
Other common causes of the above errors, or other errors
It is possible that SMTP connections of this sort have been disallowed my your IT department or provider, Or that you have not fully completed the required setup in your google account for SMTP Relay services. See
It never arrived
  • Give it a couple more minutes... sometimes emails are slow.
  • Check the junk / spam folder in the planned recipients email account
  • Ensure that all addresses have been entered properly
  • Contact your IT department to see if it has been caught up in their filters before it got delivered

Limitations of using your own SMTP server

The main limitation of this method, is HirePOS can only use two different emails to send out, Unless your email account has permissions to "Send as" a different account in the same domain.


Connecting your own SMTP server is far from the only option available for setting up spam free email with your branding on them. Consider authenticating your domain with HirePOS (giving HirePOS proper permission to pretend to be you when sending email).

Many people find that custom branding is less important than ensuring the mail absolutely arrives at its destination. If this sounds like you, consider using the in-built, ready to go, option.
