ChimpMatic connects Contact Form 7 to the email platform you already use. One plugin covers eight integrations: Mailchimp, Brevo, MailerLite, Klaviyo, Campaign Monitor, GetResponse, EmailOctopus and Moosend. So you pick a provider inside any form, map your fields, and every submission lands in the right list.

All eight integrations
Each guide below walks you through that provider’s API key, list choice, field mapping and opt-in behavior.
MailchimpConnect with one-click OAuth or an API key, then choose an audience, map merge fields, and pick single or double opt-in for each form.
BrevoPaste an API key, then choose a list and map contact attributes. You can subscribe people directly or send a confirmation email first.
MailerLitePaste an API token, then choose a group and map subscriber fields. Double opt-in follows your account setting, so nothing is overridden.
KlaviyoPaste a private API key, then choose a list and map profile properties. Confirmation follows the list, so your flows keep working.
Campaign MonitorPaste an account API key, then pick any client's list and map custom fields. Each list keeps its own single or confirmed opt-in setting.
GetResponseGenerate an API key, then pick a list, which GetResponse calls a campaign. After that, map the name and your custom fields.
EmailOctopusCreate an API key, then pick a list and map its fields. On double opt-in lists, new contacts stay pending until they confirm.
MoosendCopy your API key, then pick an email list and map custom fields. It adds new subscribers only, so existing ones are never overwritten.
How it works
- First, install ChimpMatic Lite and edit any Contact Form 7 form.
- Next, open the Chimpmatic tab, choose your provider and connect your account.
- Then select the destination list, audience or group, and map your form fields.
- Finally, set the opt-in behavior, save, and submit a test entry.
Each form has its own Chimpmatic tab. That means different forms can feed different providers, lists or campaigns on the same site.
Which of the integrations fits you?
Start with the platform you already pay for, because moving lists is the expensive part. If you are still choosing, these rules of thumb help:
- Mailchimp has the deepest support, including one-click OAuth and per-form double opt-in.
- Brevo, MailerLite and EmailOctopus suit smaller budgets, since all three have free plans.
- Klaviyo fits stores that run their marketing on flows.
- Moosend only ever adds new subscribers, so existing contacts are never touched.
