Connect Contact Form 7 to Mailchimp, Brevo, MailerLite & Klaviyo
Connect Contact Form 7 to Mailchimp, Brevo, MailerLite & Klaviyo
Description
A Mailchimp integration for Contact Form 7 that also connects forms to Brevo, MailerLite, and Klaviyo. Send form submissions to email marketing lists, audiences, or groups without replacing Contact Form 7 or adding a separate automation platform.
Choose a provider for each form, connect the account, select a destination, and map Contact Form 7 fields to subscriber fields. Existing Mailchimp forms keep their saved audience, field mappings, credentials, and opt-in settings after upgrading.

Built for Contact Form 7
ChimpMatic adds a focused integration panel to each Contact Form 7 form. It does not replace your forms, introduce another form builder, or require a generic automation service between WordPress and your email provider.
Wondering how this compares to the alternatives? We set out the trade-offs in our Mailchimp plugin comparison and our marketing automation comparison.
ChimpMatic Pro
ChimpMatic Pro is an optional add-on for teams that need advanced provider features, expanded field mapping, advanced consent controls, subscriber tagging, and priority support. ChimpMatic Lite remains a complete Contact Form 7 integration on its own.

Faq
Version 0.9.81.12 supports Mailchimp, Brevo, MailerLite, and Klaviyo. You select one provider independently for each Contact Form 7 form. See the integrations overview.
Open the ChimpMatic tab in the Contact Form 7 editor, select Mailchimp, connect with OAuth or an API key, choose an audience, and map the form’s email field. You can then configure consent and single or double opt-in. Follow the Mailchimp setup guide.
Open the ChimpMatic tab, select Brevo, enter a Brevo API key, choose a list, and map the form fields to Brevo contact attributes. You can subscribe the contact directly or use a Brevo confirmation email. Follow the Brevo setup guide, or read more about the Contact Form 7 Brevo integration.
Yes. Select MailerLite in the ChimpMatic tab, connect with an API token, choose a group, and map the Contact Form 7 email field and subscriber fields. MailerLite applies the account’s API double-opt-in setting. Follow the MailerLite setup guide.
Yes. Select Klaviyo in the ChimpMatic tab, connect with a private API key, choose a list, and map Contact Form 7 fields to Klaviyo profile properties. Consent behavior follows the selected Klaviyo list. Follow the Klaviyo setup guide.
Usually it is the audience selection, a required merge field that is not mapped, or an opt-in checkbox that was never ticked. We walk through the seven most common causes.
Yes. Existing configurations default to Mailchimp and retain their saved audience, field mappings, API credentials, and opt-in behavior.
Read more about the Contact Form 7 Mailchimp integration.
Yes. A newsletter form can send to MailerLite while a lead form sends to Brevo, for example. Every form stores its own provider, credentials, destination, mappings, and opt-in configuration. The same applies to multiple Mailchimp audiences.
Yes, but the control differs by provider. Mailchimp offers single or double opt-in per form. Brevo can send a confirmation email. MailerLite follows the account’s API double-opt-in setting. Klaviyo follows the selected list’s consent behavior.
Read more about provider-specific double opt-in, or the Mailchimp double opt-in setup.
Lite maps the required email address plus up to four additional form fields. Compatible ChimpMatic Pro features can expand the mapping limit.
Read more about Contact Form 7 field mapping, Mailchimp audience fields and merge tags, and the default audience fields.
Yes, by mapping those form fields to the matching audience fields. See sending the subscriber name and sending birthday fields.
Yes. Choose the group in the form’s settings. There is background on how Mailchimp groups work and on replacing groups.
Require an opt-in checkbox before subscriber data is sent, and choose the confirmation behavior your provider offers. We cover the practicalities in collecting consent with GDPR.
We keep honest comparisons, including where the other side is stronger: see our Mailchimp plugin comparison and our marketing automation comparison.

Reviews
Awesome! This is the best plugin!
By 
Thank you for your support. The service and problem resolution are simply wonderful!
Decent plugin but has some issues
By 
The settings for this plugin aren't its own page, but a page within each CF7 form. I'm not sure if that's any more of a limitation than strange UX. The plugin creates a cmatic_daily_cron cron job that is set to run once daily but often gets stuck and won't run and refuses to run manually. Again, it appears to function fine without it - but then what is that cron supposedly doing?
Recently, there's a new admin bar icon in the top bar, with a nag for upgrading. That alone is enough to make me not want to upgrade to pro (for some clients I use pro, for others there's no budget for that).
Finally, when navigating away from any CF7 page, if this plugin is active the browser warning "Changes you made may not be saved" shows - whether you saved or not, whether you changed anything or not.
Anyway, its pretty good, but not great. (minus one star for the nag; minus one star for the browser warning and the cron job error). These errors make me doubt if its working and want to constantly audit the MailChimp list, but with dozens of sites using it, that's a big task.
Great plugin and super fast live support

CAN NOT DELETE ACCOUNT
By 
Be Aware, once you signup for pro there is NO way of CANCELING the account. Which means they keep taxing your account every year! I am not sure how they can do this as this is not a subscription service and is illegal. We have tried to get in touch but they do not answer the emails. So it looks like now we need to go to the POLICE.
Maybe they can answer here???
Great plugin
By 
Tried few plugins and that is the only one that worked without any problems. Great plugin, thank you.
Info user disappered
By 
I had to deactivated it because caused me the disappearance from backend all the users data in their profile.
SCAM!! IMPOSSIBLE TO CANCEL ACCOUNT
By 
BE AWARE of this plugin - It is now a SCAM! DO NOT SUBSCRIBE to premium as you will not be able to cancel. They NO LONGER provide support, the website does not work when you try to access your account, and they NO LONGER answer the emails but they still charge you and they make it very hard to cancel or change account details. VERY DISAPPOINTED - and can't understand how this is allowed on the WordPress community! Now we will need to go to the bank to blacklist this user and account and look for another provider! READ REVIEWS BEFORE YOU COMMIT!!
Thank you!
By 
Responsive, friendly, and solved the issue too - huge thanks!
No support!!! Even though you are paying for it!!!
By 
DON'T buy Chimpmatic!!! On their website, Chimpmatic write and promise that you get support as a paying customer, but the truth is that they never reply to the support tickets that we have sent them.
DON'T buy Chimpmatic!!!
