Sunset Email Flow Explained
Sunset email flow explained: Klaviyo's 180-day Sunset (Email) segment, Top Growth $0.01 median RPR, and suppress vs delete.
TL;DR: A sunset email flow is a last-chance hygiene sequence for confirmed ghosts, then suppress. Klaviyo’s Sunset (Email) segment uses Created ≥180 days, ≥5 emails in ~72 weeks, and zero forever engagement. A labeled Top Growth panel (n=9) puts median sunset RPR at $0.01. Judge it on clean suppression, not cart dollars.
Introduction
Founders ask for a “good sunset open rate” the way they ask for a good cart rate. That is the wrong scoreboard. Sunset exists to confirm someone is gone so you can stop mailing them, stop paying for them as an active profile, and stop training mailbox providers that your domain is noise.
The full cluster map lives in the email marketing guide.
Sunset email flow explained means defining the unengaged segment, sending a short last-chance series, tagging non-responders, and suppressing them without deleting history you still need. Revenue scorecards for cold lists live in winback email benchmarks. Broader ESP ladders live in email marketing benchmarks by industry. Complaint floors that make hygiene urgent live next to Google’s bulk sender rules in the sibling deliverability queue.
- Klaviyo’s Help Center defines a sunset flow as a last-ditch effort to re-engage, then delete or suppress anyone who stays silent, so inactive profiles stop counting toward billing (Klaviyo).
- The prebuilt Sunset (Email) segment requires Created at least 180 days ago, Received Email at least 5 times in the last 72 weeks, and zero Opens, Clicks, Active on Site, Viewed Product, Checkout Started, and Placed Order over all time (Klaviyo).
- Suppression recommendations on the Suppressed profiles page tighten the age gate to Created at least 365 days while keeping the same “never engaged” pattern (Klaviyo).
- Top Growth’s labeled DTC panel (n=9 brands, July 2025 to June 2026) puts Sunset / re-engagement median click at 0.41%, conversion at 0.01%, and RPR at $0.01 (top quartile $0.11) (Top Growth).
- Google tells bulk senders to keep Postmaster spam rates below 0.10% and avoid reaching 0.30% (Google).
- There is no public dataset for an Omnisend or Klaviyo all-account official sunset $/email census. Agency “15-25% open / 3-8% re-engagement” averages stay out of the charts.
What a Sunset Email Flow Is
A sunset email flow is an automation that targets long-unengaged subscribers with a short last-chance series, then marks non-responders for suppression so they stop receiving marketing email and stop counting as active profiles. It is a hygiene machine with a goodbye letter attached, not a discount ladder for people who already ignored you.
It is not a weaker winback. Winback still believes a lapsed buyer or cold subscriber is worth a revenue try. Sunset assumes silence has already spoken and asks one last time before you cut the send path. Klaviyo’s Help Center says you should sunset lists and segments you plan to suppress, because once suppressed they cannot receive marketing emails, and the flow’s job is to catch anyone who still engages before that cut (Klaviyo).
If you are still hunting recovery dollars on a cold cohort, stay on winback email benchmarks. If you are protecting inbox placement and plan limits, this page is the operating manual.
Why a Sunset Email Flow Matters
A sunset email flow matters because unmonitored inboxes drag open rates, invite spam complaints, and inflate the active-profile count you pay for, while a short last-chance series still salvages the few who wake up before you suppress. Skip it and you subsidize ghosts with both cash and sender reputation.
- Billing follows activity status. Klaviyo states that suppressing profiles keeps them in the account without marketing sends and without contributing to plan limits, while deleting erases history permanently (Klaviyo). Sunset is how you get to that suppress decision without guessing.
- Deliverability is the real ROI. Klaviyo warns that continuing to send to the long-inactive cohort lowers open rates, the signal mailbox providers use for inbox versus spam (Klaviyo). Google’s bulk sender guidance puts Postmaster spam-rate floors at keep-below 0.10% and avoid 0.30% (Google).
- Revenue metrics will look “broken.” Top Growth publishes sunset / re-engagement median RPR at $0.01 versus abandoned checkout $2.57, and says sunset fails on click by design while succeeding on hygiene (Top Growth).
- Winback already framed the split. Operators and Klaviyo pair win-back, then sunset, then stop mailing ghosts (winback email benchmarks; Klaviyo RPR).
- Suppress is not delete. Suppress preserves analytics and future re-subscribe paths. Delete is for data-deletion requests or profiles you are sure you never need (Klaviyo).

How a Sunset Email Flow Works
A sunset email flow works when a profile enters a strict unengaged segment, receives one to three last-chance messages, exits on real engagement, and gets tagged for bulk suppression if silence holds through a short grace period. The dollars will look tiny. The hygiene is the product.
The official Sunset (Email) segment
Klaviyo’s recommended segment (also the Segment Library “Sunset (Email)” preset) is AND-logic all the way down (Klaviyo):
| Condition | Rule |
|---|---|
| Marketing eligibility | Person can receive email marketing |
| Profile age | Created is at least 180 days ago |
| Proof you actually mailed them | Received Email at least 5 times in the last 72 weeks |
| Zero engagement forever | Opened Email 0, Clicked Email 0, Active on Site 0, Viewed Product 0, Checkout Started 0, Placed Order 0 (all time) |
That definition is stricter than “no open in 90 days.” It requires a long tenure, repeated sends, and zero lifetime marketing and site engagement. Mis-wire AND versus OR and the segment either stays empty or vacuums recent buyers. Klaviyo’s troubleshooting guide calls that out for sunset flows specifically (Klaviyo).
The 365-day suppress recommendation twin
On the Suppressed profiles page, Klaviyo’s suppression recommendations use the same never-engaged pattern but require Created at least 365 days ago, plus ≥5 emails over roughly the last 72 weeks, never opened or clicked, and never visited or purchased (Klaviyo). Treat 180 days as the flow-trigger library default and 365 days as the safer bulk-suppress recommendation band. Do not invent a third “industry average inactivity window.”
Message count, grace period, and the Unengaged tag
Klaviyo’s from-scratch recipe: add flow filters so anyone who opens or clicks since starting the flow exits, send one to three emails (not more), wait a grace period after the last email (3 days if you send daily, 7-10 if less often), then update a boolean profile property such as Unengaged = True (Klaviyo). Unsubscribes suppress automatically. Silent non-responders need the tag, then a Suppress current members action on a segment of Unengaged = True.
Klaviyo is explicit: it is not currently possible to suppress profiles as a native Flow Action. Bulk suppress from Lists & segments (or an API/webhook recipe) is the path (Klaviyo; Community).
Suppress versus delete
| Action | Profile remains? | Marketing email? | Counts toward plan limits? | Recoverable? |
|---|---|---|---|---|
| Suppress | Yes | No | No | Can unsuppress (with rules) |
| Delete | No | N/A | N/A | No |
Prefer suppress for list hygiene. Delete when a person requests erasure or you are certain you never need the record (Klaviyo). Note the manual re-suppress cooldown: after a manual suppress then unsuppress, you generally cannot manually suppress again within 90 days (Klaviyo).
What “good” performance looks like
| Metric | Labeled figure | How to read it |
|---|---|---|
| Sunset / re-engagement median CTR | 0.41% (n=9) | Cold cohort; under 1% by design |
| Top-quartile CTR | 0.96% | Still not a cart flow |
| Median conversion | 0.01% | Hygiene job, not checkout recovery |
| Median RPR | $0.01 | Contrast checkout $2.57 (n=13) |
| Top-quartile RPR | $0.11 | Upside tail, not a week-one target |

Opens after Mail Privacy Protection
Klaviyo’s exit filters often key on opens and clicks. Apple Mail Privacy Protection can inflate opens (email marketing benchmarks by industry; how iOS privacy changes affected performance marketing). Prefer clicks, site activity, and purchases when you tighten filters. Do not celebrate a “recovered” open that is only a privacy proxy fetch.
What this page refuses
There is no public dataset for a verified Klaviyo or Omnisend all-account sunset $/email or open-rate census matching agency “15-25% open / 3-8% re-engagement” tables. feat. does not invent a national sunset conversion rate. Use Klaviyo’s published segment rules plus labeled small panels, then measure your own suppress volume.

How to Build a Sunset Email Flow
Building a sunset email flow means copying Klaviyo’s Sunset (Email) logic (or your ESP’s equivalent), limiting the series to three messages, tagging silence, and bulk-suppressing without deleting. Run winback first when the cohort still deserves a revenue try. Score success on suppress volume and complaint-rate headroom, not on cart RPR.
- Name the job. Winback for recoverable cold contacts. Sunset for the last chance before suppress. Do not merge both into one “re-engagement open rate” cell (winback email benchmarks).
- Build the Sunset (Email) segment. Use Klaviyo’s AND stack: can receive email, Created ≥180 days, Received Email ≥5 in 72 weeks, zero lifetime opens/clicks/site/product/checkout/order (Klaviyo).
- Trigger a segment-based flow. Use the prebuilt “sunset unengaged subscribers” flow or build from scratch with the same segment (Klaviyo).
- Filter out engagers. Exit anyone who opens or clicks (prefer click/site/purchase where MPP muddies opens) since starting the flow.
- Send one to three last-chance emails. Plain-text friendly, clear unsubscribe and preferences links, subject lines that admit goodbye is possible. Grace period 3 days or 7-10 after the last send (Klaviyo).
- Tag Unengaged = True, then suppress. Create a segment on that property and use Suppress current members. For automation, use Klaviyo’s documented API/webhook recipe, not a fake native suppress action (Klaviyo).
- Report hygiene, not vanity. Track suppress count, spam rate versus Google’s 0.10% / 0.30% floors, and only then glance at Top Growth’s $0.01 median RPR humility check (Google; Top Growth).
Frequently Asked Questions
These answers restate the Sunset (Email) segment rules, the suppress-versus-delete choice, the Top Growth hygiene floor, and why open-rate vanity fails so a founder can quote labeled sources without inventing a national sunset benchmark. Keep them next to the tables above when you brief a teammate or paste a short answer into Slack.
Q: What is a sunset email flow? A: It is an automation that sends a short last-chance series to long-unengaged subscribers, then suppresses (or deletes) people who still do not engage. Klaviyo positions it as list hygiene and billing control, not as a top revenue flow.
Q: How is a sunset flow different from a winback flow? A: Winback still chases recovery from lapsed buyers or cold subscribers. Sunset confirms ghosts before you cut marketing sends. Run winback first when the cohort deserves a try, then sunset non-responders (winback email benchmarks).
Q: What segment should trigger a Klaviyo sunset flow? A: Start from the Sunset (Email) library definition: can receive email, Created ≥180 days, Received Email ≥5 in 72 weeks, and zero lifetime opens, clicks, site activity, product views, checkouts, and orders. Suppression recommendations on the Suppressed profiles page use a 365-day created gate with the same never-engaged pattern.
Q: What is a good sunset email conversion or RPR? A: A labeled Top Growth DTC panel (n=9) shows median conversion 0.01% and median RPR $0.01 (top quartile $0.11). Those numbers look like failure next to checkout $2.57. They are the humility floor for a hygiene job. There is no public Omnisend or Klaviyo all-account sunset $/email census in the sources used here.
Q: Should I suppress or delete unengaged profiles? A: Prefer suppress for hygiene: the profile stays for analysis, cannot get marketing email, and does not count toward plan limits. Delete only for erasure requests or records you are sure you never need. Klaviyo does not offer suppress as a native Flow Action, so use bulk suppress or a documented API webhook.
Conclusion
A sunset email flow is how you stop mailing people who already voted with silence. Klaviyo’s 180-day Sunset (Email) segment, the 365-day suppress recommendation twin, and Top Growth’s $0.01 median RPR all point the same way: measure clean cuts, not cart envy.
