Connect OptinMonster to Mailchimp, Constant Contact, Brevo (the Integrations card no longer says Sendinblue), WooCommerce, WPForms or Marketo. Marketo is not on the 2026 pricing grid; the old docs URL 404s.

Choose the connection for your workflow, then verify what reaches the destination. These are source-based findings; the checks below are our evaluation guidance, not hands-on test results.
The pricing FAQ says installation requires a website that permits custom JavaScript in the page body.
The plan cards group Shopify, WooCommerce, Magento and other ecommerce integrations under Growth.
The vendor describes native ESP/CRM connections, while pricing separates Basic, Advanced and Pro integrations.
These offer routing options beyond a native connection.
The features page describes a JS Events API for custom behavior.
Suggested setup checks
Use a repeatable test so each change has a clear expected outcome.
Name the intended audience, campaign and destination before changing settings.
Check installation and display separately from the form submission and follow-up message.
Record what passed or failed, then repeat the same test after the fix.
6 of 6 guides available
Authorize Constant Contact, select the destination list and save. Verify mapped fields and follow-up emails with a controlled test submission.
Connect the plugins, choose where the campaign can appear and test your cart conditions. WooCommerce targeting requires Growth according to the vendor.
Sendinblue rebranded to Brevo. In OptinMonster, search Integrations for Brevo, paste an API key, pick a list, save. Coupon-wheel fields are not sent.
Publish a WPForms form, assign the WordPress site in OptinMonster's Publish view, drop the WPForms block, pick the form. It will not show in the builder canvas.
Connect the native Marketo integration, choose the destination partition and list, and test contact delivery separately from follow-up emails.
Integrations view, Mailchimp, paste an API key, pick an Audience. Double opt-in is on by default. Groups can be automatic or shown as checkboxes.
Questions before you decide
No. The features page describes native ESP/CRM connections, while pricing divides integration access by tier. Confirm the required fields and destination behavior in the connector’s own setup guide before purchasing or migrating.
Consider them when a native connector does not cover the required workflow. Both are listed on Pro. Include external automation costs and responsibility for failed deliveries in the decision; the presence of a routing option does not prove the whole workflow is configured.
Do not assume it does. The pricing cards place ecommerce integrations on Growth, while the general installation FAQ describes JavaScript installation across platforms. Check the exact store-data action you need against the selected plan.
Submit a fresh test contact, inspect the destination list and fields, and check the expected message. If the same contact can enter more than one flow, check for duplication. This is an acceptance check for the documented lead-routing capability, not a report of a live account test.
The JavaScript Events API distinguishes an attempt from a completed tracking action. Its documentation says om.Analytics.impression fires when tracking is attempted, while om.Analytics.track is the event to use to know tracking occurred. Similarly, om.Campaign.canLoad does not guarantee display. Use the event that matches the outcome you need, then validate the downstream analytics destination.
OptinMonster’s HubSpot guide separates contact delivery from HubSpot email automation. If the test contact reaches HubSpot but no message arrives, inspect the HubSpot workflow and its eligibility rules. Use a fresh test address because an existing contact can be handled differently, and keep the submission time so you can trace the same attempt.
The current connection guide says the native integration selects a HubSpot Static List; Active Lists are not offered in that selector. If you assign a HubSpot form, its fields must match the OptinMonster campaign or the submission can fail. Verify the chosen list, form and mapped properties with one controlled submission.
