FlowSync vs Substack

FlowSync keeps your email marketing platform in sync with what happens on your WordPress site. When someone subscribes to a membership, completes a WooCommerce order, or submits a form, FlowSync sends them to the right list, tag, or segment in Brevo, Mailchimp, HubSpot, Klaviyo, and more. The data goes straight from your site to your CRM, with no Zapier or middleware in between.

Substack helps anyone set up a blog and email newsletter and publish directly to their audience and get paid through subscriptions. No tech knowledge is required. It’s free to get started on Substack. If you turn on paid subscriptions, Substack will keep a 10% cut of revenues.
