Adding an SSL Certificate to Your Custom Marketing Domain

You will need a custom marketing domain with an SSL certificate to host your Act-On pages and content. Web pages without SSL enabled will show security warnings in most modern browsers.

Add a Custom Marketing Domain 

A custom marketing domain lets you use your company name in the URLs for Act-On content (forms, landing pages, etc.) instead of a generic Act-On-generated address. If you want a new domain to use for Act-On content, you can purchase it at the hosting provider of your choice.

Note: Custom marketing domains cannot include special characters such as underscores.

To connect your custom domain to Act-On:

  1. Login to your Act-On account 
  2. Go to Content > Branding > Domain
  3. Highlight the Default Marketing Domain and copy it to use below
  4. Have your IT or domain host create a CNAME called "marketing" or "info"
  5. Point the CNAME to the Default Marketing Domain that you copied
  6. Go to Content > Branding > Domain, click Edit, then add your newly created CNAME

Important: Your new domain is not secured. An SSL certificate must be added via the steps below.

Add an SSL Certificate

This certificate is required to reach your audience – without it, your content will be blocked by most web browsers. Even if you have SSL configured elsewhere already, you will need a new certificate to add to your Act-On domain. This will also allow to track visit data on web pages secured via HTTPS.

Here's the process to add or update a certificate:

  1. Provide some company information to Act-On Support (see below)
  2. Support will reply with a certificate signing request (CSR)
  3. Buy an SSL certificate from the provider of your choice
    Note: The certificate needs to be non-wildcard and either an OV, DV, or EV SSL certificate for an Apache HTTP server
  4. Send the certificate details to Act-On Support so it can be installed on your marketing domain

If you are renewing a certificate and have your previous CSR from Act-On, you can skip the CSR request steps, buy the certificate, and contact support with the certificate details.

Request a CSR

Please log in to submit your request.

Act-On Support will follow up with you to continue the installation.

Technical Details

The technology that Act-On uses to support 'https' pages when hosting a certificate is Transport Layer Security (TLS SNI). Below is a list of browsers that currently support TLS SNI:

  • Opera 8.0 and later (the TLS 1.1 protocol must be enabled)
  • Internet Explorer 7 or later (under Windows Vista and later only, not under Windows XP)
  • Firefox 2.0 or later
  • Curl 7.18.1 or later (when compiled against an SSL/TLS toolkit with SNI support)
  • Chrome 6.0 or later (on all platforms – releases up to 5.0 only on specific OS versions)
  • Safari 3.0 or later (under OS X 10.5.6 or later and under Windows Vista and later)
