The Domain Masking Proxy feature allows you to mask all your primary domain by many secondary domains. From everyone else's perspective, this effectively creates a new website for you.

You may want to separate your domains for various use cases. For example, you may have a different domain for sending enewsletters, a different domain for your main business, and another domain for sending out alerts for your app.

There can be a few downsides to traditional domain forwarding:

• 1. Risk of shared IPs. Domain forwarding is often done at the registrar level, where your domain shares a “forwarding IP” with hundreds or thousands of others. If any of those shared IPs get blacklisted, or if a poor-quality IP is assigned, your domain could end up on a blacklist too.

• 2. Easily Detected Redirects. When email service providers (ESPs) or bots visit your site, they can easily detect 301 or 302 redirects. This makes it easy to distinguish which domains are simply redirecting versus hosting real websites.

• 3. SSL Certificates. Secondary domains typically don’t come with SSL certificates by default, which can make them appear less secure.

Your website host likely only allows authenticated requests from your primary domain. Any request from another source is automatically handed off to the main domain. In this instance, your proxy falls back to a hosted domain redirect along with all its benefits.

Some website hosting companies don’t allow proxy connections. In this case, they perform a redirect at their end. You still benefit from a “hosted domain redirect over a clean IP with SSL,” but you lose the mask.

In this case, we can recommend setting up a single landing page through Framer or proxy friendly website hosts, and then mask all secondary domains to that landing page.

We’ve not observed any downsides yet. If someone alerts us to downsides, we’re happy to dig in and come up with workarounds. We strongly believe that the community is in this battle together!

As for SEO, with EmailGuard, there's no need to worry. We take care of the domain masking headers to ensure your secondary domains are not picked up by search engines. Other masking providers might not do this, so I’d make sure you ask them first before buying.

Your web host is ensuring that requests to its servers only come through a default set of "accepted" domains. This is possible in some cases. You can either whitelist all your secondary domains with your webhost, disable your shared website firewall, or allow your domain masking proxy IP in your safe list.
