To save subscriber information that is entered on your website, you need to connect the Growtheme to Mailchimp. This involves typically three steps. First you have to Authorize the Growtheme to access your Mailchimp Account Data. Next you need to specify a list to save subscribers to. And third, you need to decide if you want to use Single or Double Optin.

Additionally, if you use a Double Optin Process, you need to configure Mailchimp to use the custom Growtheme Thank You Page instead of the standard Mailchimp Thank You Page.

1. Authorize the Growtheme

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


Next you have to authorize the Growtheme to access your Mailchimp Account Data


You only authorize your local install and the Growtheme to access your Account Data. The actual Data itself is not accessed by us or anybody else and remains save inside your Mailchimp Account. You can revoke access at anytime from within your Mailchimp Account Dashboard.

Click on the green button that says Click here to connect to Mailchimp.


You will be redirected to a new page, where you have to login with your Mailchimp username and password in order to connect the Growtheme to your Mailchimp Account.


After you have logged in, you will be automatically redirected back to the Growtheme Settings Page with a notice that the Growtheme has successfully been connected to Mailchimp.

Additionally the Mailchimp API Status Field should indicate that you are successfully connected to Mailchimp.


2. Select a List to use

If you have several lists inside your Mailchimp account, you need to choose one Mailchimp List. This is the list where your subscribers will be saved in. If you have just one list, it will already be selected.



The Growtheme caches all requests to the Mailchimp API. This speeds up your Growtheme Settings Panel and prevents that you have to wait every time you change something until the Mailchimp Server responds. If you have made any changes inside your Mailchimp 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.


If you haven’t created a List in Mailchimp yet, do this now. You can do this inside your Mailchimp Dashboard on the Lists Page or by clicking on this link.



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

3. Choose Single or Double Optin

With Mailchimp you have the option to choose between a Single Optin or Double Optin Process. If you decide to use Double Optin, visitors will have to confirm their email address before being subscribed to your Mailchimp 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 Mailchimp Blogpost or their Knowledge Base Article about the Double Optin Process.

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


If 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 Mailchimp 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 Mailchimp 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 Mailchimp as well.

Now go to Mailchimp. Inside the Mailchimp Dashboard go to Lists and choose the List you are using the Growtheme with and have selected in the second step.


Then click on Signup Forms and select the General Forms Option



On this page you normally can configure the look and feel of your Mailchimp Signup Forms. As we are using the Growtheme to show our Signup Forms, you don’t need to change anything in particular on these signup form settings as these changes won’t take effect.


One thing you can and should configurate on this particular Mailchimp Page is the Opt-in confirmation email and additionally the optional Final "welcome" email.

The opt-in confirmation email will be sended if you have Double Optin enabled and asks the visitor to confirm their email before subscribing.

The Final "welcome" email is optional, but can be sended once a visitor is subscribed to your email list.

From the Dropdown Menu choose Signup "thank you" page.


Paste the Thank You Page URL you have copied into the text field and click on the Save Button.


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

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