We're proud to offer custom domain forwarding—you can learn more here. At this time, however, we do not currently offer domain masking.
This means that if guests type in your longer Zola web address (ie. zola.com/wedding/jackandjill), they'll be redirected to the same site as your custom domain (ie. jackalsojill.com) but they'll still see the longer Zola web address in their browser.
Please note: In cases where domain masking is set up on an account, it does appear to work, but will show as "not secure" and will prevent couples and guests from utilizing all features on their website.
Stay tuned for more custom domain updates!
