Because Unbounce uses a rotating IP address, we need a way of pointing a subdomain to our landing page, and a CNAME record is the best way to do this.

Who Should I Contact at my Company to Set Up a CNAME Record?

If you aren't setting up the CNAME record yourself, reach out to someone who has administrative access to your domain and DNS settings. Think your webmaster, web developer, or someone in your IT department.

You may want to copy and paste this email template which explains exactly what you need:

Who Hosts the Landing Pages?

All Unbounce pages are hosted on Unbounce servers.

What are the Benefits to Unbounce Hosting My Page?

Unbounce servers are fast and reliable: We have an average page load time of 0.4 seconds and we've maintained an uptime of 99.99% since we launched in December of 2009. If for any reason your website goes down, your subdomain landing pages will be up and running without any interruption to your campaigns.

Having your landing pages separate from your website also allows your Marketing department more control of the pages without involvement from IT (past the initial set-up process).

What are Unbounce's Security Features?

Unbounce provides SSL certificates and we provision SSl on all Pro Plan domains by default. For more information, check out: Securing Your Landing Page Domain with SSL. Our SSL provider is GlobalSign (

If your server team requires all pages to serve through https, you do not have to provide certification. We’ve purchased our own SSL certificate and take care of issuing, managing, and renewing the certificate. This protects any internal policies you may have, as we will manage the SSL for all your Unbounce landing pages so there is no need for you to share your SSL certificates with anyone.

The Unbounce system operates in multiple geographically-diverse data centers, and is monitored externally for availability and uptime every 60 seconds.

Our staff are alerted in the event of any interruption, and we maintain the ability to switch operations to other data centers within minutes in the case of a prolonged interruption in service at any one data center.
