We're proud to offer custom domain forwarding—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.
Stay tuned for more custom domain updates!
