Bwak News

Bwak News is a newsletter reader that never asks for Gmail or Outlook access. Each newsletter gets its own dedicated alias — approve a sender once, and issues land in a feed instead of your inbox. Kill one alias without touching any other subscription.

Built solo, in public, from a farm in Tennessee.

FlowSync

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.
