Connecting one mailbox to Guestway without changing your main email setup
Last updated: February 12, 2026
This guide explains how you can display emails from a single address such as bookings@yourdomain.com inside Guestway while keeping your existing email provider and mailboxes unchanged.
This situation is common for hotels and property managers who already run their email through a hosting provider and only want Guestway to handle guest communication.
Important concept: only one MX destination per domain
Every domain has MX records.
These records tell the internet which server receives emails for that domain.
A domain cannot deliver incoming emails to two different mail servers at the same time.
So if you change the MX records to Guestway:
• Emails will arrive in Guestway
• Emails will stop arriving in your current hosting mailbox
That is why directly changing MX records is usually not the right approach when you only want one address connected.
Recommended solution: Email forwarding
The cleanest and safest setup is to keep your current mail server as the main receiver and forward one specific address to Guestway.
This gives you the best of both worlds:
• Your current mailboxes keep working normally
• Guestway receives guest communication
• No downtime
• No DNS risks
What the final flow looks like
Guest sends email → bookings@yourdomain.com
↓
Your mail provider receives it
↓
Your mail provider automatically forwards it to Guestway
↓
Email appears inside Guestway Inbox
Your team can still open the original mailbox if needed.
Step by step setup:
Step 1. Do NOT change MX records
Keep your domain DNS exactly as it currently is.
Do not add Guestway MX records.
Step 2. Create a forwarder in your mail hosting
In your email hosting provider (Google Workspace, Microsoft 365, cPanel, IONOS, etc.) create a forward rule:
Forward from
Forward to
(the inbound address provided by Guestway)
Save the configuration.
Step 3. Test the connection
1. Send an email to bookings@yourdomain.com from an external address
2. Wait about 10 to 60 seconds
3. Open the Guestway Inbox
You should now see the message appear in Guestway.
The email will also remain available in your normal mailbox.
Why this is the best approach
No DNS modifications
No risk of email downtime
Works instantly
Keeps your existing provider
Only the guest facing mailbox is connected
This is the recommended setup whenever only one or a few addresses need to be handled inside Guestway.
Optional advanced setup: Full Guestway email domain
If you later want Guestway to fully manage email sending and receiving, the recommended approach is to use a subdomain.
Example
guest communication → guests.yourdomain.com
internal company email → yourdomain.com
This allows:
• Your internal emails to stay on your current provider
• Guestway to manage guest communication
• No server conflicts
This setup requires DNS changes and dedicated MX records but keeps everything separated and stable.
Summary
If you only want one address such as bookings@yourdomain.com inside Guestway:
Use forwarding
Do not change MX records
If you want Guestway to fully manage communication for a dedicated domain:
Use a subdomain with Guestway MX records
