To save subscriber information that is entered on your website, you need to connect the Growtheme to Campaign Monitor. This involves typically three steps. First you need to get an API Key and save it into the Growtheme Options. Second you need to specify a list to use. Third you need to decide between Single or Double Optin.

Additionally, if you use a Double Optin Process, you need to configure Campaign Monitor to use the custom Growtheme Thank You Page.

1. Get your API Key

Inside the Growtheme Options Panel » Email Provider click on the Campaign Monitor Logo to show the Campaign Monitor Options.

Next you need to enter your personal Campaign Monitor API Key.

Click on the link below the Text field to get your Campaign Monitor API Key.

A new tab will open where you have to login with your Campaign Monitor username and password if you are not already logged in.


After login you have to navigate to your account settings. The way is different depending on your Campaign Monitor Settings.

Show API Key in the Campaign Monitor agency version

Inside your Campaign Monitor Dashboard click on Account Settings.

_images/campaignmonitor-account-settings.pngYou will see a link called Show API Key. Click on it to show your API Key.

_images/campaignmonitor-show-api-key-agency.pngMark the complete Key with your mouse and copy it.


Show API Key in in the Campaign Monitor non-agency version

Inside your Campaign Monitor Dashboard click on your Account Name (1) in the top right corner. Than click on Manage Account (2) and choose API Keys (3)

_images/campaignmonitor-manage-account.pngYou will see a link called Show API Keys. Click on it to show your API Key.

_images/campaignmonitor-show-api-key.pngMark the complete Key with your mouse and copy it.


Paste the API Key inside the Growtheme Options

Now go back to the Growtheme Options Tab. Paste the copied API Key into theCampaign Monitor API Key text field.

Next click on Save Changes to connect the Growtheme to Campaign Monitor.

If you have copied and pasted the API Key correctly, you will see a success notice that the Growtheme is now connected to Campaign Monitor.

Additionally the Campaign Monitor API Status Field should indicate that you are successfully connected with Campaign Monitor.


If you haven’t created a List in Campaign Monitor yet, do this now.

If you use Campaign Monitor in the agency version:

Choose a Client you want to use first.


Then go to List & Subscribers and click on Create a new list. If you use the non-agency version you go directly to this page.


2. Select a List to use

If you have several lists or clients inside your Campaign Monitor account, you need to choose oneCampaign Monitor List. This is the list where your subscribers will be saved in. If you have just one list and client, it will already be selected.


Currently it’s not possible to choose more than one list of your Campaign Monitor Account at any given time.


The Growtheme caches all requests to the Campaign Monitor API. This speeds up your Growtheme Settings Panel and prevents that you have to wait every time you change something until theCampaign Monitor Server responds. If you have made any changes inside yourCampaign Monitor Account that haven’t showed up within the Growtheme Settings Panel yet, you can use the Refresh Connection Button to delete all cached files and reset the connection.

3. Choose Single or Double Optin

With Campaign Monitor you have the option to choose between a Single Optin or Double OptinProcess. If you decide to use Double Optin, visitors will have to confirm their email address before being subscribed to your Campaign Monitor list.


For some countries like Germany this is not an optional option, but required by law. Please review the specific laws of your own country regarding email marketing.


Using Double Optin usually results in a higher open rate, less spam reports and a general higher quality list. If you want to know more about this check this Knowledge Base Article about the Single and Double Optin Process.

You can easily enable or disable the double optin process inside the Growtheme Options »Email Provider » Campaign Monitor » Use Double Optin?

_images/use-double-optin.pngIf you decide to use a Single Optin Process, you are ready to go. The Growtheme will automatically redirect users to your custom Thank You Page after signing up. The Confirmation Page won’t be used in this case.

If you want or need to use the Double Optin Process you need to configure Campaign Monitor to use your own custom Thank You Page.

4. Setup the Thank You Page


This is only required if you use a Double Optin Process

We have to setup Campaign Monitor to use our own custom Thank You Page. This Page will show up once a subscriber clicks on the confirmation link inside the confirmation email.

To do this, we first need the URL of our custom Thank You Page. Inside your WordPress Dashboard go to Growtheme » Customize.

Within the Wordpress Customizer go to the Thank You Page Section.

Next select and copy the Permalink of your Thank You Page.


You can switch the permalink of your Thank You page to anything you like, as long as it is a valid URL. Just remember that when you change the URL of your Thank You Page, you will have to update the Thank You Page URL within Campaign Monitor as well.

Now go to Campaign Monitor. Inside the Campaign Monitor Dashboard go to Lists & Subscribers (If you use the agency version, select a client first as explained above).

Next choose the List you are using the Growtheme with and have selected in the second step.

_images/campaignmonitor-choose-list.pngOn the next page click on the right site on Customize landing pages



On this page you can customize as well The email that asks them to confirm they subscribed.

Additionally you can send them a final welcome email at the bottom of this page.

Scroll down to the section named The success page after they confirm their email.

Paste the Thank You Page URL you have copied into the text field.

_images/campaignmonitor-success-page.pngDon’t forget to save the settings by clicking on Save changes at the bottom of the page.


This page will now show up once a subscriber clicks on the link inside the opt-in confirmation email.

You are now successfully connected to Campaign Monitor. Everything is set up. You can now go ahead and customize the Growtheme Options to your needs.
