By default, emails are sent from [email protected] and can be monitored within outgoing correspondence.
However, if you prefer to use your property's email address for outgoing emails, and review all email traffic in your property's email application, you need to configure this using the article below. This configuration applies to Room Billing, Invoice Reprint and new confirmation emails, as well as paylinks if you have GuestPay.
Step 1: Access the configuration
⚠️Important: Configuration can only be completed by an Admin user. If you are not, please contact an Admin User on site to complete the following steps.
To access the configuration of outgoing room billing, invoice reprint and new confirmation emails, follow the steps below:
Click this link: Guestline Settings.
Enter your specific Site ID and navigate to the Email Config section.
Step 2: Configure your email
There are 2 options for configuring the outgoing address. Please choose the one appropriate for your mailbox:
Option 1: Microsoft & Google mail providers
If your mail provider is with either Microsoft or Google, please use the ‘Sign in with Microsoft’ or ‘Sign in with Google’ options. This option will require you to supply the email address and password of the mailbox you wish to use and will authenticate with the provider.

Option 2: All other mail providers
Do NOT use this method if your mail provider is Microsoft or Google, follow the information above in Option 1.
To set up SMTP log in details, follow the steps below:
Enter the correct From name and Email Address into the Email Sending Settings.

You must also provide the SMTP Settings. These can be obtained from your properties’ IT Team - Guestline does not have this information to be able to populate this for you.
Click Save in the top right corner.
Click on the top right to Send Email Test. If the test email fails to send, please remove the configuration and try again. Leaving incorrect configuration in place will prevent emails being sent from Rezlynx.
Troubleshooting
I cannot access the link in step 1: If you are not able to access the link this may mean that you do not have the user permissions or are not an Admin User. Please contact an Admin User on site, as Guestline are not able to complete these steps for you.
We don't use Microsoft or Google mail so I need to set up SMTP. But I don’t know the SMTP Log in details: This information is specific to your IT team and your property and so Guestline cannot provide this information. We would recommend reaching out to your IT Team for this information. Alternatively, you may be able to obtain this information from your mail provider.
