Why Campaignly needs Tag Manager access

Google Tag Manager holds the tags on your website, including Analytics and ads tracking. Campaignly needs permission to publish in the container that is installed on your live site.

Need to create an account first?

If you do not have Tag Manager yet, create the account and your first container. A container that is not on the site cannot collect data. Installing it is a separate step. Follow the Google Tag Manager setup guide, then return here.

What you'll need

  • Sign-in access to the Tag Manager account for your website
  • Account Administrator permission, so you can add a user
  • The container ID on your site, which looks like GTM-XXXXXXX
  • The Campaignly email we sent you, from your Campaignly onboarding message

Invite Campaignly

  1. Sign in at tagmanager.google.com.
  2. Open the account for your website.
  3. Click Admin.
  4. In the Account column, select User Management.
  5. Select the plus button, then Add users.
  6. Enter the email address in your Campaignly onboarding message.
  7. Set the account permission to User. Choose Administrator if Campaignly should also manage who else can use the account.
  8. Under container permissions, find the container installed on your website and set it to Publish.
  9. Click Invite.

Publish lets Campaignly edit the container and publish changes. Read, Edit, and Approve stop short of publishing, so they are not enough for onboarding.

If you have more than one container, match the ID (GTM-…) to the snippet on your live website. Access on a test container does not cover the live site.

If something looks wrong

There is no Tag Manager account for this site. Create the account and container first. Install the container with the setup guide, then send the invite.

You cannot add users. Ask someone with Administrator on the Tag Manager account to invite the onboarding email and set the live container to Publish.

Google’s own steps are in Manage users and permissions in Tag Manager.
