Wix and MailChimp: How to Import Contacts

Most small business owners come to Wix and Mailchimp from opposite directions. They set up a Wix website because it is quick and manageable without a developer, then discovered Mailchimp when they started thinking seriously about staying in touch with customers. At that point, a reasonable question emerges: do you need both, and if so, how do you get them talking to each other?

The short answer is yes, you can use both — and for growing businesses, connecting Wix and Mailchimp is usually worth the setup time. Wix handles your website and collects contacts through forms and sign-up tools. Mailchimp takes those contacts and gives you the automation, segmentation and reporting that Wix’s native email tools do not match at scale.

This guide covers how to import and manage contacts within Wix, the three main methods for connecting Mailchimp to your site, how to fix the issues that catch most people out, and what UK businesses specifically need to know about GDPR before moving contact data between the two platforms.

Wix Email Marketing vs Mailchimp: Which Is Right for Your Business?

Both tools can send email newsletters. The question is whether Wix’s native functionality is enough for where your business is going, or whether the extra capability of a dedicated email platform is worth the additional cost and setup time.

Where Wix email marketing works well

Wix’s marketing tools are built directly into the site dashboard, which means no third-party accounts, no API connections, and a genuinely simple setup. If you send a monthly newsletter to a few hundred contacts and you want everything in one place, it does the job. The drag-and-drop email editor uses the same interface as the site builder, so the learning curve is minimal.

For service businesses in Northern Ireland and across the UK — a local accountancy practice sending monthly updates, a plumbing company emailing seasonal offers — Wix’s native tools are often sufficient at the early stage.

Where Mailchimp pulls ahead

Mailchimp’s real advantage is in automation and audience segmentation. You can build multi-branch customer journeys (send one sequence to contacts who opened your welcome email, a different one to those who did not), run A/B tests on subject lines, and get detailed reporting on click maps and revenue attribution.

The analytics are also more granular. Wix gives you open rates and click rates; Mailchimp lets you see exactly which links were clicked, by which contacts, and correlate those actions with purchases if your store is connected.

Deliverability is another practical factor. Mailchimp’s shared sending infrastructure has an established reputation with inbox providers, whereas Wix’s default sender domain does not match inbox providers’ requirements for growing lists.

Pricing comparison in GBP

Both platforms charge based on list size. The table below shows approximate tiers as of early 2026. Always check each platform’s current pricing page before committing, as these figures change.

Verify current UK pricing at wix.com/upgrade/website and mailchimp.com/pricing before making a decision.

Mailchimp charges based on the total number of contacts in your audience, including unsubscribed contacts — so a large inactive list can push your costs up. Wix charges based on your overall site plan rather than contact count, making it a better value for businesses with large but lightly used databases.

The verdict: when to stick with Wix and when to connect Mailchimp

Stay with Wix email if your list is under 1,000 contacts, you send simple newsletters, and you want everything in one dashboard.

Connect Mailchimp if you want automated sequences, list segmentation, detailed analytics, or you plan to grow your list significantly. The setup takes an afternoon, and the additional capability is worth it for businesses treating email as a serious acquisition and retention channel.

How to Import Contacts to Your Wix Website

Before you connect any external email platform, you need your contacts organised within Wix. The Wix CRM — accessed via the Contacts section of your dashboard — is where all subscriber data lives.

Adding contacts manually

Log in to your Wix account and go to your site’s dashboard. In the left-hand menu, select Contacts. Click the New Contact button in the top right corner. A panel will open where you can enter the contact’s name, email address, phone number, and address. You can also add custom fields — useful if you want to record a contact’s company name, role, or any other information specific to your business.

Once saved, the contact is automatically added to your list. Click on any contact to open a side panel where you can add notes, set reminders and attach files to that contact record.

Importing contacts from Gmail

To import contacts from Gmail, go to your Contacts section in the Wix dashboard and click the More Actions dropdown in the top right. Select Import Contacts, then choose Import from Gmail.

Wix will redirect you to Google’s authorisation screen. Choose the Google account you want to import from and approve the permissions. A window will show how many Gmail contacts are available and let you choose whether to mark them as subscribers.

Be cautious here: importing contacts as subscribers without their explicit consent for marketing communications is a GDPR compliance issue for UK businesses. Read the GDPR section below before you proceed with this step.

Each Wix site can hold up to 200,000 contacts — verify this limit against the current Wix plan documentation, as it may vary by subscription tier.

Importing contacts via CSV file

If you have contacts stored in another email platform, a spreadsheet, or an older CRM, export them as a CSV file first. The process works with Gmail, Yahoo, Outlook and most other providers.

To export from Gmail: Open Google Contacts, click the More menu in the top-left sidebar, and select Export. Choose the contact group you want and select Google CSV format. Download the file.

To import into Wix: Go to Contacts, click More Actions, then Import Contacts, then select the CSV option. Upload your file, and Wix will map the columns to the appropriate fields. Before importing, open the CSV in a spreadsheet application to check that the data is clean — blank email fields or mixed formats will cause import errors.

Make sure every contact you import has at least one of the following: a valid email address, a phone number, or a physical address. Without at least one of these, Wix will not import the record.

Using contact labels to organise your list

Once contacts are in your Wix CRM, labels help you filter and segment them. Labels are tags you apply to contacts so you can send emails to specific groups rather than your whole list.

To manage labels, go to Contacts in your dashboard, click More Actions, and select Manage Labels. Create labels that reflect your business structure — for example, ‘Newsletter subscribers’, ‘Past clients’, ‘Event attendees. Apply them to individual contacts or in bulk.

Wix also applies some labels automatically. Contacts who make a purchase are labelled ‘Customers’. Contacts who fill in a form are labelled ‘Contacted me’. These automated labels save manual work for active sites.

How to Connect Mailchimp to Wix

Once your contacts are organised in Wix, connecting Mailchimp lets you use Wix forms and the Wix contact database as the source of your Mailchimp audience, while running all actual email campaigns from within Mailchimp.

Method 1: The native Wix App Market integration

This is the most straightforward route for most small businesses.

1. Open your Wix dashboard and click Add Apps in the left menu.
2. Search for Mailchimp in the App Market.
3. Click Add to Site and follow the prompts to log into your Mailchimp account.
4. Once connected, choose which Mailchimp audience you want to sync your Wix contacts to.
5. Configure which Wix forms should automatically feed new subscribers into Mailchimp.

The native integration is free to install, though you need active accounts on both platforms. It works well for straightforward setups where you want form sign-ups on your Wix site to flow directly into a Mailchimp audience.

Method 2: Using Zapier for more reliable syncing

The native Wix-Mailchimp integration has known limitations: it does not always sync historical contacts reliably, and there can be delays when a contact updates their details on one platform but not the other. For businesses where list accuracy matters, a Zapier connection gives more control.

Zapier acts as a bridge between the two platforms. You can set up automated triggers — for example, when a new contact is added to a Wix label, add them to a specific Mailchimp audience segment. You can also trigger actions based on changes to contact fields, form submissions, or purchase events.

Zapier has a free tier covering basic connections. For more complex multi-step automations, a paid plan is needed. The setup requires no coding but needs around an hour to configure and test properly.

Method 3: Embedding a Mailchimp form in your Wix site

If you want Mailchimp’s form builder and double opt-in process on your Wix site without relying on the platform integration, you can embed a Mailchimp signup form directly using an HTML iframe element.

In Mailchimp, go to Audience > Signup forms > Embedded forms. Copy the HTML code. In your Wix editor, add an HTML iframe element to the page where you want the form, and paste the Mailchimp code. Save and publish.

Note that embedded forms can affect mobile layout. If you need a custom form that matches your site’s design precisely, ProfileTree’s web design team can integrate Mailchimp forms cleanly into any Wix build without layout issues.

Common Integration Problems and How to Fix Them

The Wix-Mailchimp connection works well when it is set up correctly, but a handful of issues trip up almost everyone at some point. Most are quick to resolve once you know where to look.

Contacts not syncing from Wix to Mailchimp

This is the most common issue with the native integration. The most common cause is a mismatch in the double-opt-in settings between the two platforms. If Mailchimp is set to require double opt-in, but a contact in Wix has not confirmed via email, Mailchimp will not accept the record.

Fix: Check your Mailchimp audience settings under Settings > Audience name and defaults. If double opt-in is enabled, make sure your Wix forms send a confirmation email before marking contacts as subscribed. Disabling double opt-in removes the friction, but note this has implications for GDPR consent documentation — see the section below.

Pop-up conflicts

If you are using both a Wix pop-up to capture subscribers and a Mailchimp embedded form on the same page, they can conflict — showing two sign-up prompts or triggering unexpected behaviour on mobile. Use one method per page. For most Wix sites, the Wix pop-up feeding into the native Mailchimp integration is the simpler choice. If you need Mailchimp’s specific pop-up features (exit intent, time delay, behavioural triggers), use Mailchimp’s own pop-up builder and disable the Wix pop-up on that page.

The integration keeps disconnecting

The native Wix-Mailchimp connection uses an API key. If you recently changed your Mailchimp password or regenerated your API keys, the integration will break. Go to the Wix App Market, find the Mailchimp app, and re-authenticate to reconnect using a fresh key.

Historical contacts did not transfer

The native integration syncs new contacts from the connection date onward. It does not automatically import your existing Wix contact list into Mailchimp. To move existing contacts, export them from Wix as a CSV (More Actions > Export Contacts), then import that CSV directly into your Mailchimp audience under Audience > Add Contacts > Import Contacts.

GDPR and Data Transfer: What UK Businesses Need to Know

This section is specifically for businesses based in the UK and Northern Ireland. Much of the guidance written about Wix and Mailchimp integration is US-centric and skips this entirely. It matters.

Mailchimp is a US-based platform. When you connect Mailchimp to your Wix site, and contacts flow across, you are transferring personal data from a UK/EU server environment to the United States. This transfer is subject to UK GDPR.

What this means in practice:

• Your privacy policy must state that contact data is processed by Mailchimp and may be transferred to the United States.
• Contacts must have given explicit consent to receive marketing communications before you import them into Mailchimp. Importing your whole Gmail contact list and marking them as subscribers without prior consent is not GDPR-compliant.
• Consent must be specific: ‘I agree to receive marketing emails from [your business]’ rather than a general terms acceptance.
• You must be able to demonstrate that consent was given, and when. In Mailchimp, you can add a note about the consent source when importing.

Mailchimp holds a Data Processing Agreement you can find in your account settings under Account > Legal, which covers their obligations as a data processor. Signing this is good practice for any UK business using the platform.

If you are unsure whether your current data collection process is compliant, the ICO (Information Commissioner’s Office) at ico.org.uk publishes clear guidance for small businesses. ProfileTree’s digital marketing strategy service includes a review of consent mechanisms and alignment of privacy policies for clients setting up new email marketing systems.

When to Bring in Professional Support

For many small businesses, the steps in this guide are enough to get a functional Wix-Mailchimp setup running. There are situations, though, where the DIY route creates more problems than it solves.

If your business is migrating from one platform to another and you have a large contact database, getting the import, tagging and consent documentation right from the start saves significant effort later. A disorganised Mailchimp audience with duplicate contacts, missing consent fields, and no segmentation is harder to fix than to set up correctly in the first place.

If you want to build a digital marketing system that uses your website, email and content together as a joined-up strategy — rather than three separate things you manage manually — ProfileTree’s digital marketing strategy service covers the full setup: platform choice, audience architecture, consent flows, automation planning and content strategy. We work with SMEs across Belfast, Northern Ireland and the wider UK who want to move beyond trial-and-error into a system that grows their business.

Conclusion

Getting Wix and Mailchimp working together is not complicated, but it does require a few deliberate decisions upfront: which connection method suits your setup, how you want to organise your contact list, and whether your data collection process meets UK GDPR requirements.

For most small businesses, the native Wix App Market integration is enough to get started. If your list grows or your campaigns become more sophisticated, switching to a Zapier connection or a fully separate Mailchimp setup gives you more control without rebuilding everything from scratch.

The platform you use matters less than the habits you build around it. A clean, well-segmented contact list with clear consent records is more valuable than any particular tool. Get that foundation right, and the rest follows.
