Sending Corksy Segments to Klaviyo & Mailchimp (Classic vs. Dynamic)

Last updated: October 1, 2026

Corksy has two versions of customer segmentation, and which one your account uses affects how segments reach Klaviyo or Mailchimp. Both are live — accounts are on one or the other.

Which version do I have?

Look at the segmentation area in your Corksy admin:

  • Version 1 (Classic): the section is labeled just “Segmentation.” You build segments by choosing from dropdowns / predefined options, then manually send them to your email platform.

  • Version 2 (newer, beta): the section has a Beta sticker and is labeled something like “Segmentation and Email Marketing.” You can type what you want in plain language to build a segment, and you can build and send email campaigns inside Corksy. Segments can also keep themselves up to date automatically.

Still not sure? Contact support@corksy.io. For more on the newer version, see Segmentation 2.0 (Beta).


Version 1 (Classic): send a segment manually

  1. Go to the Segmentation area under Marketing and create or open a segment (choosing from the predefined options).

  2. Open the segment and click Actions → Send.

  3. Choose Klaviyo or Mailchimp and give it a list/tag name so it’s easy to find in your email platform.

  4. Save to push the audience.

Key things to know:

  • This is a one-time push (a snapshot). If the audience changes later, send it again to update your email platform.

  • Corksy pushes first name, last name, and email. Only marketing opted-in customers are sent.

  • Klaviyo and Mailchimp de-duplicate by email, so re-sending won’t create duplicate contacts.


Version 2 (newer): type-to-build segments that can auto-sync

On the newer version you type what you want (for example, “customers who bought Pinot Noir and attended a tasting”) instead of picking from dropdowns, and segments can keep themselves current:

  • Static segments push once at creation (like Classic).

  • Dynamic segments sync once per day (12:00 AM PST) — Corksy automatically adds newly qualifying customers and removes those who no longer qualify, as a marketing list.

  • You can also build and send email campaigns directly in Corksy (no export needed).
