# How to Send New Account Registration Email to Mailchimp in Elementor?

## 

- The Plus Addons for Elementor WP Login & Register widget adds a MailChimp Subscribe checkbox to the registration form, so new members can opt in while they sign up.
- The Plus Addons for Elementor Pro requires Mailchimp API Key and List ID setup in The Plus Addons > Settings, and the API key includes the data centre part after the dash, such as -us21.
- Mailchimp sends the contact only when the box is ticked and the account is created, with email, first name, and last name included; Double Opt-In makes new contacts pending until they confirm.

Asking new members about your newsletter while they sign up saves them a second form, and saves you copying addresses into Mailchimp.

The **MailChimp Subscribe** option of the **WP Login & Register** widget from The Plus Addons for Elementor adds a subscribe checkbox to the registration form.

## Before You Start

- **Edition:** **Pro** — the WP Login & Register widget is only part of The Plus Addons for Elementor Pro. The free plugin lists it as a locked Pro widget and does not add it to Elementor.- **Widget to enable:** WP Login & Register, switched on under **The Plus Addons > Widgets**.- **WordPress setting:** **Settings > General > Membership: Anyone can register** must be ticked, or the register form shows a notice instead of its fields.- A Mailchimp API key and the ID of the audience (list) to add people to.

## Step 1: Save Your Mailchimp Keys

- Go to **The Plus Addons > Settings** and find **Mailchimp** in the **API** group.- Click its settings icon, paste the **API Key** and the **List ID**, and save.

The API key must be copied whole, including the part after the dash (for example `-us21`). A key without it is ignored.

## Step 2: Add the Checkbox to the Form

- Add the **WP Login & Register** widget and set **Type** to **Register** or **Login and Register**.- Open **Register Extra Options** and turn on **MailChimp Subscribe**.

- Change the checkbox text in **Register Options > MailChimp** if you like.- Publish the page.

## Options

| Setting | What it does |
| ------- | ------------ |
| **UnCheck** | Shows the checkbox unticked, so members opt in themselves. By default it is ticked. |
| **Double Opt-In** | Adds new contacts as pending, so Mailchimp asks them to confirm first. |
| **Groups** > **Enter Group ID** | Adds the contact to Mailchimp groups. Separate several IDs with ` | `. |
| **Tags** > **Enter Tag** | Tags the new contact. Separate several tags with `|`. |
| **Individual List ID & API Key** | In the **Mailchimp Individual List ID & API Key** section: use a different API key and list for this widget only. |

## How It Behaves

- The contact is only sent to Mailchimp when the box is ticked and the account was created.- The member's email, first name and last name are sent.- Without **Double Opt-In**, the contact is added as subscribed straight away.

## Limitations

- **Mailchimp errors are silent.** If the key or list is wrong, the account is still created and nobody sees an error; the contact is simply missing in Mailchimp. Check your audience after a test sign-up.- With **UnCheck** off, the box is ticked for everyone who does not untick it. Check the consent rules that apply to your audience.- The widget is part of The Plus Addons for Elementor Pro only.

## Troubleshooting

### New members do not appear in Mailchimp

Check that the API key includes its data centre part after the dash, that the List ID belongs to that account, and that the test member left the box ticked. With **Double Opt-In** on, contacts appear as pending until they confirm.

## Frequently Asked Questions

**Q: What do I need before I can send new account registrations to Mailchimp in Elementor?**
A: The setup depends on four things: The Plus Addons for Elementor Pro, the WP Login & Register widget enabled under The Plus Addons > Widgets, WordPress membership registration turned on at Settings > General, and a Mailchimp API key plus audience List ID. The API key has to include the data centre suffix after the dash, like -us21, or Mailchimp ignores it. That detail matters because a missing suffix looks valid but will not connect to the right account.

**Q: Why are new members not appearing in Mailchimp after registration?**
A: The most common failure is a bad API key or List ID. Mailchimp errors are silent here, so the account still gets created in WordPress and nobody sees an error message. A second gotcha is Double Opt-In: when it is on, contacts stay pending until they confirm, so they will not look like active subscribers right away. A test sign-up with the checkbox ticked is the fastest way to verify the audience is receiving contacts.

**Q: How does the Mailchimp subscribe checkbox behave on the registration form?**
A: The checkbox only sends a contact when two things happen: the box is ticked and the account is actually created. The member’s email, first name, and last name are sent to Mailchimp. If Double Opt-In is off, the contact is added as subscribed straight away. That makes this better for simple newsletter capture than for workflows that need confirmation first.

**Q: Can I use a different Mailchimp list or tags for this registration form?**
A: The widget supports both per-widget targeting and segmentation. In the Mailchimp Individual List ID & API Key section, you can use a different API key and list just for that widget. It also supports Groups by entering Group IDs separated with |, and Tags by entering multiple tags with |. That gives you a clean way to route different registration forms into different audiences or segments without changing your main Mailchimp setup.

**Q: Should I leave the subscribe checkbox checked by default or turn on UnCheck?**
A: UnCheck changes consent behavior in a meaningful way. When it is off, the checkbox is ticked by default, so most people will be subscribed unless they actively untick it. When it is on, members opt in themselves because the box starts unticked. That matters if your audience needs explicit consent rules, since the page calls out checking the consent rules that apply to your audience.

**Q: What happens if Double Opt-In is enabled for new registrations?**
A: Double Opt-In makes new contacts land in Mailchimp as pending until they confirm their subscription. That slows down list growth a bit, but it also gives you cleaner consent because people have to verify first. In this setup, don’t expect immediate active subscribers after signup. If you are testing, check whether the contact shows as pending before assuming the integration failed.
