From Austin to Gavin: what to build in Klaviyo

From Austin · 26 September 2026

Hi Gavin,

We're rebuilding all of Hypertune's email. Vinson has written every email, the design team is building three new templates, Kamil is sending the data Klaviyo needs, and you build and test everything in Klaviyo. Here is exactly what I need from you.

This week: account setup

  1. Smart Sending on for every marketing flow and campaign.
  2. Default exclusions on every campaign: anyone paying or on a trial, anyone who got a flow email in the last 14 days, and every yearly subscriber.
  3. Fix the segment IB // Paid & Cancelled users: cancelled in the last 90 days and Successfully Paid zero times in the last 35 days. Today it includes people who are paying.
  4. Successfully Paid as the conversion metric on the account and every flow.
  5. Sender name "Austin from Hypertune" on every flow.
  6. Delete the 13 draft flows that never sent.
  7. Switch off the old account-created flow before anyone is unsuppressed.
  8. Unsuppress every paying customer the team suppressed (about 480). Never touch an unsubscribe, bounce or spam complaint.
  9. Request transactional status from Klaviyo for the failed payment, trial ending and renewal emails.
  10. Confirm the June and August suppressions were about the plan limit, and price a temporary plan step up for the trial win-back.

Then build, in this order. Each link has the full copy, timing, trigger and build notes.

Trial users win-back. About 21,000 people who tried Hypertune were suppressed and never unsubscribed. Build the win-back from the trial users report: a list-triggered flow, about 1,000 unsuppressed a day, three emails, a 50/50 split test of designed against plain, and non-clickers suppressed again at day 14. Confirm their original consent is still valid first. Stop a wave if bounces pass 2% or spam 0.1%. Kamil sends the lists and the discount codes.

How to build: follow the build rules for sender, links, tracking, Smart Sending and transactional settings. Build every email from the design team's new templates, not the old designs. Put a test profile through every flow and send Vinson desktop and mobile screenshots before anything goes live.

Every Friday: what shipped, what's blocked and on whom, and hours used. Please send your hours estimate for all of the above before you start.

Thanks,

Austin
