Description
FlowSync is a WordPress CRM and email automation plugin. It helps you sync members, customers, users, and form leads to Brevo, Mailchimp, HubSpot, Klaviyo, and more based on real activity on your site.
Build contact sync workflows from three parts:
- Trigger – an event happens, such as a user registration, subscription change, order update, or form submission. (Page visit tracking is part of FlowSync Pro.)
- Conditions – choose who or what the workflow should apply to.
- Actions – send email, assign roles, update user meta, delay work, sync contacts, add contacts to CRM targets, remove contacts from CRM targets, or send an outgoing webhook.
Workflow data, run logs, settings, and tracking events are stored on your own WordPress site. External CRM services are contacted only when you configure that integration and a workflow action needs to use it.

These integrations contact no central service:
- FluentCRM and MailPoet: used locally through their WordPress plugin APIs when those plugins are installed and active.
- Sendy, listmonk, and SuiteCRM: self-hosted software. FlowSync sends requests only to the installation URL you enter in the integration settings. Software:
https://sendy.co/,https://listmonk.app/,https://suitecrm.com/.
Installation
- Upload the plugin folder to
/wp-content/plugins/, or install it from the Plugins screen in WordPress. - Activate the plugin.
- Go to FlowSync -> Integrations and configure any CRM services you want to use.
- Go to FlowSync -> Workflows and create your first automation.
FAQ
-
Does this require a third-party service?
-
No third-party service is required to create local WordPress workflows. CRM integrations call their respective provider APIs only after an administrator configures credentials and a workflow uses that provider. OAuth-based connections use the FlowSync OAuth broker described below.
-
Is page tracking enabled by default?
-
No. Page-visit tracking is disabled by default. When enabled, FlowSync stores local event records that can include a user ID for logged-in users, event type, page URL, and sanitized event metadata.
-
What REST API permissions are used?
-
Administrative REST endpoints require a logged-in user with
manage_optionsand WordPress REST nonce authentication through theX-WP-Nonceheader. Public tracking and CRM webhook endpoints are intentionally public, rate-limited or provider-verified, and do not expose protected WordPress data.
