Mailhook and Klaviyo: Open House Sign-In Capture Template

Turn open-house sign-in sheets emailed as a CSV into Klaviyo profiles, each added to a follow-up list segmented by the property the attendee visited.

What It Builds

This Spojit template starts with a Mailhook trigger: agents forward the sign-in CSV to your unique Mailhook address and a run begins. An Attachment node pulls the CSV bytes, the CSV connector parses the rows, and a Loop node walks each attendee. For every row, a Klaviyo Connector node in Direct mode creates or updates a profile and subscribes it to a follow-up list tagged with the visited property.

The Prompt

Paste this into Miraxa and it builds the workflow, connecting the tools for you:

Build a workflow with a Mailhook trigger so agents can email an open-house sign-in sheet as a CSV attachment. Fetch the CSV attachment, parse each row into name, email, and phone, and read the property address from the email subject. For each attendee, add or update a Klaviyo profile and subscribe it to a follow-up list, tagging the profile with the property they visited so I can send property-specific follow-ups.

Connectors Used

Mailhook - the trigger; each forwarded email starts a run.
Attachment - fetches the sign-in CSV bytes from the email.
CSV - parses attendee rows into structured fields.
Klaviyo - creates profiles and subscribes them to the follow-up list.

Customize It

Change the list name in the prompt, add fields like budget or preferred_area if your sheet includes them, or have Miraxa read the property from a property column instead of the subject line. You can also point each property at its own dedicated list.

Tips

Your Klaviyo connection needs write scope on profiles and lists.
Keep the Klaviyo node in Direct mode for one exact action per row and no AI cost.
Header row names in the CSV should match the fields named in the prompt.
