Commerce_MailChimp

Commerce_MailChimp is an official modmore extra for Commerce. During checkout, customers can be signed up to a predefined MailChimp list automatically.

Features

• Opt-In: Add an opt-in checkbox to your cart, address or payment checkout templates.
• Double Opt-In: When enabled, customers will be sent a verification email before they're subscribed to the specified list.
• List Selection: Select the MailChimp list to subscribe customers to directly within the Commerce configuration page.
• Subscription Status: View a customer's MailChimp subscription status within the Commerce order detail page. If subscribed a link to that subscription within MailChimp is also provided.
• Assign groups: Select from a list of groups to automatically assign a customer to when they subscribe. (Added in v1.1)

Requirements

• MODX 2.6.5 or later.
• PHP 7.1 or later.
• MailChimp API Key.
• At least one list set up in the MailChimp account.

Installation

Install via the MODX package manager using either the official repo or the Modmore repo.

Usage - Configuration

Once the installation has completed, there's some initial configuration that's needed before the module can be used.

From the Commerce dashboard, click the tab Configuration then select Modules and then Commerce_MailChimp.

This will open a pop-up window and a field where you can paste in your MailChimp API key. Click Save.

Providing the API key was valid, you'll be presented with some extra fields.

• MailChimp List: This dropdown box will be populated with lists from your MailChimp account. Select one.
• MailChimp Groups: If groups are enabled on your MailChimp account, after selecting a list, you'll be presented with a choice of groups to automatically assign a customer to when they subscribe.
• Address Type: Here you can select whether the shipping or billing address is used for subscriptions. Select one.
• Enable Double Opt-In: (Optional) Enable this if you would like customers to be sent a verification email before they're subscribed to the list.

Click save again!

Usage - Checkout Templates

Decide which template you would like to add the opt-in checkbox to:

• frontend/checkout/cart.twig
• frontend/checkout/address.twig
• frontend/checkout/payment-method.twig

In the template of your choice, find the <form> </form> tags then add the following between them.

{% if mailchimp_enabled and not mailchimp_subscribed %}
    <label class="c-subscribe-newsletter">
        <input type="checkbox" name="mailchimp_opt_in" value="on">
        {{ lex('commerce_mailchimp.subscribe_to_newsletter') }}
    </label>
{% endif %}

This will hide the checkbox if the customer is already subscribed but show it if they're not. You can customise the markup as you'd like, so long as the name is mailchimp_opt_in and the value is on.

The {{ lex('commerce_mailchimp.subscribe_to_newsletter') }} is a lexicon placeholder that renders the text: Subscribe to newsletter? You can replace this with your own.

If opting-in isn't important on your platform, you can instead add a hidden input between the form tags that will subscribe everyone without asking them.

<input type="hidden" name="mailchimp_opt_in" value="on">

If the customer opted in to the newsletter, they will be added to the list when the order is paid.
