# Booking.com Emails

## How Booking.com works

Booking.com allows you to send messages to your guests, through their private relay emails. A private relay email is an email address handed out by booking.com and masks the real email of the user. <br>

**Example:**

`hwetra.6123268@guest.booking.com`

Each booking coming from Booking.com will have such an email. And your OTA, or yourself have been using it to email to this as well.&#x20;

### Booking.com Restrictions

Booking.com uses private relays to prevent unnecessary messages and/or SPAM from being send to their guests / travelers. However, you have control over what can be send to your guests.&#x20;

### How to allow HolidayHero emails in Booking.com?

Besides the strict rules of booking.com, they allow you as a host to determine what to be send to the guests. Follow the steps below, to ensure that HolidayHero emails are let through.&#x20;

### Add email addresses and links

{% hint style="info" %}
You might be asked to re-authenticate your account, ensuring it is you that makes the changes. This is normal.&#x20;
{% endhint %}

1. Add the following two email addresses to the **Your email addresses** section
   1. `noreply@holidayhero.app`
   2. `noreply@holidayhero.com`
2. Add the following two links to the **Your approved links** section
   1. `[brand-name].holidayhero.com`
      1. **IMPORTANT:** replace the brand name with your subdomain. See [Brands - General ](/the-basics/brands.md)
   2. `hdyhr.com` <- we use this domain for short codes and short redirect links.&#x20;

It now should look like this. (Obviously, if you have multiple e-mail addresses, feel free to add them there).&#x20;
