Connecting 1and1 IONOS domain to your Ecwid Instant Site

You can make your Ecwid Instant Site available via a custom domain. Having your own domain helps personalize your online business, makes it look professional and improves your website ranking in Google, Yahoo and other search engines.

If you already have a domain name from 1&1 IONOS, you can link it to your Ecwid Instant Site in two steps:

  1. Specify the domain name in your Ecwid admin.
  2. Point the domain to your Ecwid site in your 1&1 account.

It might sound complicated, but don't worry — we will guide you through the whole process. Once everything is set up, your Ecwid Instant site will open at your domain name, via secure HTTPS connection (i.e. the web-address will begin with https://).

You need to be on a Venture, Business, or Unlimited plan before you can connect a custom domain to your Instant Site. A free SSL certificate is included.
You can use a custom domain on any paid plan. If you downgrade to a Free Ecwid plan, your custom domain will be replaced with a free Ecwid subdomain.

Setting up the domain in the Ecwid admin

To link your domain with your Ecwid Instant Site, you should first enter your custom domain name in your Ecwid admin:

  1. From your Ecwid admin, go to Website.
  2. In the Domain name and site address block, click Change Address.
  3. In the pop-up window that you’ll see enter your custom domain in the Use your own domain name field (you should enter your root domain, i.e. without www part).
  4. While you are entering your custom domain name in this field, you can see the instruction for a further domain setup below. Copy the Ecwid’s IP-address that is offered to you there (, or, or as you will need it later.

  1. Click Save.

Setting up the domain in the 1&1 (IONOS) account

To finish up linking your Ecwid Instant Site with your domain, you should now make changes in your domain settings. You need to add an A record and a CNAME record in your domain host account:

  1. Sign in to your 1&1 account at
  2. From the Select Product dropdown choose Domains & SSL.
  3. Click the gear icon under Actions next to the domain you're connecting to your Ecwid site and select DNS:

    • Leave the TTL option as 1 hour.
    • In the preview section, click Do not add DNS record for www.
    • Click Save.

Make sure to delete other A or AAAA records from your domain settings as they might conflict with this new A record pointing to your Ecwid site.
  1. Click Add Record and now select the CNAME type.
  2. On the next page, enter the following data for the CNAME record:
    • In the Host Name field, enter www.

Now please wait a bit till the changes take effect. It usually takes no longer than two hours for the DNS changes to propagate, but can take up to 24-48 hours in some cases. After that your Instant Site will be available at your own domain.
