Updated Email Preferences, Klaviyo

Updated Email Preferences over time. Profiles that adjusted their subscription preferences rather than fully unsubscribing, a healthier outcome. How to read it, why it matters, and how to act on it.

Metrics type: Supporting Metrics • Category: Email Marketing

When a subscriber would rather hear from you less than not at all, that is a win. This tracks the people who turned the dial down instead of walking out the door.

At a glance

A time-series of profiles that updated their email or subscription preferences in the selected period, for example by changing send frequency or opting down to fewer topics through a preference centre, rather than unsubscribing outright. This is the healthy alternative to a hard unsubscribe: a profile that opts down stays on the list, keeps receiving the mail it asked for, and remains reachable. Reading this line against the unsubscribe trend tells you whether your preference centre is doing its job of catching would-be leavers. A rising preference-update line alongside a falling unsubscribe line is one of the better signals a list-health programme can produce.

What it counts	The number of profiles that changed their email or subscription preferences per interval, such as adjusting frequency or topic opt-downs via a preference centre, without fully unsubscribing.
API endpoint + statistics field	Derived from profile and consent changes via GET /api/profiles, with list context from GET /api/lists, bucketed per interval. Where a merchant tracks a preference-update metric event it can be cross-read via GET /api/metrics.
A healthier outcome	Distinct from an unsubscribe. A preference update keeps the profile subscribed (often to a narrower set), preserving reachability. An unsubscribe ends contact.
Lists vs segments	Preference changes apply to list and channel consent, not to segment membership, which updates automatically by rule.
Consent status	The profile typically remains subscribed after a preference update, just with adjusted settings. Contrast with the unsubscribed transition counted on the unsubscribe cards.
Chart type	Line (time-series).
Time window	Selected period, bucketed by day or week.
Alert trigger	Read as context for churn rather than a standalone alert; a healthy reading is a high preference-update line relative to unsubscribes.
Roles	owner, marketing

Calculation

Calculated automatically from your Klaviyo data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A fashion brand on Shopify that added a preference centre to its unsubscribe footer, offering “get less email” and “monthly only” options before the full opt-out. The 30-day window covers 14 Mar 26 to 12 Apr 26. All figures are illustrative.

Week (in window)	Preference updates	Unsubscribes	Ratio updates : unsubs
14 Mar to 20 Mar	210	540	0.39
21 Mar to 27 Mar	280	500	0.56
28 Mar to 03 Apr	460	470	0.98
04 Apr to 12 Apr	520	430	1.21
Window total	1,470	1,940	0.76

Updates as share of total opt-out intent = 1,470 / (1,470 + 1,940) = 43%
Trend in ratio (week 1 to week 4)         = 0.39 -> 1.21 (rising)

Five observations:

1. By the end of the window, more people opt down than opt out. The ratio climbs from 0.39 to 1.21 across the four weeks. The preference centre is increasingly catching subscribers who would otherwise have left entirely. That is the whole point of the feature.
2. 43 percent of opt-out intent was redirected into “stay, but less”. Of every 100 people who reached the unsubscribe footer with the intent to reduce mail, roughly 43 chose to adjust preferences instead of leaving. Those profiles remain reachable and revenue-generating, just at a lower frequency.
3. The rising line tracks adoption, not deterioration. A climbing preference-update line is not a warning. It usually means the preference centre is being surfaced more prominently or that frequency has crept up enough that people want to dial it back. Either way, retaining them beats losing them.
4. Read this with the unsubscribe trend, never alone. A high preference-update count is only good news if the unsubscribe line is flat or falling. If both lines rise together, the underlying issue is over-mailing, and the preference centre is merely softening the damage rather than fixing the cause.
5. Honour the new preferences or you undo the win. A profile that asked for “monthly only” and then receives three sends a week will unsubscribe for real. The value of this metric depends on the sending programme actually respecting the reduced cadence the subscriber selected.

Sibling cards merchants should reference together

Updated Email Preferences is best read as the softer counterpart to churn. Pair it with these:

Card	Why pair it with Updated Email Preferences
Unsubscribe Rate	The hard opt-out rate. A healthy programme shifts intent from unsubscribes into preference updates, so watch the two move inversely.
Unsubscribe Trend	The opt-out count over time. Read against this line to judge whether the preference centre is catching would-be leavers.
Suppressed Profiles	The other end of reachability. Preference updates keep profiles reachable; suppression removes them.
List Health Summary	The condition roll-up that preference retention contributes to.
Subscriber Growth Rate	Retaining opt-downers protects net growth by reducing the outflow side.

Reconciling against Klaviyo

Where to look in Klaviyo:

• Profiles → [a profile] → Activity shows preference and consent changes on an individual profile, useful for spot-checking what “updated preferences” means for your account.
• Analytics → Metrics for any preference-update metric event your account tracks, which gives the event-level time-series.
• Audiences → Lists & Segments to see how preference settings map onto the lists and channels a profile is subscribed to.
• Your hosted preference centre / subscription page configuration, since the options offered there determine what kinds of updates this card can count.

Why our number may legitimately differ:

Reason	Direction of divergence
Preference-centre design. This card can only count the preference options a merchant actually offers. A simple all-or-nothing unsubscribe page produces few or no updates.	Lower on accounts without a real preference centre.
Time-zone. Klaviyo buckets in account time zone; Vortex IQ buckets in UTC. Points near midnight can shift a day.	Per-interval shift; window total close.
Update vs unsubscribe classification. What counts as a “preference update” versus a partial unsubscribe depends on how consent is modelled. Edge cases can land differently between the two cards.	Variable at the margin.
Metric availability. If no preference-update event is tracked, the count derives from consent changes, which can bucket slightly differently from an event stream.	Marginal.
Page caps. Profile reads paginate at 50 per page; large windows are assembled across pages with minor mid-pull drift possible.	Marginal.

Known limitations / merchant FAQs

Why is this number low or zero for my account? The most common reason is that you do not offer a preference centre. If your unsubscribe footer is a single “unsubscribe” link with no option to reduce frequency or pick topics, subscribers have nowhere to “update preferences”, so they either stay or leave outright. Adding even a simple “get less email” option usually lifts this metric and lowers hard unsubscribes.

Is a rising preference-update line good or bad? Good, as long as the unsubscribe line is flat or falling at the same time. It means people who wanted less mail chose to stay on reduced terms instead of leaving. It only becomes a warning if both lines rise together, which points at over-mailing as the root cause.

Does a preference update keep the profile subscribed? Generally yes. The profile usually remains subscribed, just to a narrower set of mail (lower frequency or fewer topics). That is the entire benefit over a hard unsubscribe: the profile stays reachable and can still generate revenue.

How is this different from an unsubscribe? An unsubscribe ends contact; a preference update narrows it. This card counts the people who turned the dial down; the unsubscribe cards count the people who switched it off. The healthiest list-health programmes convert opt-out intent into preference updates wherever possible.

If someone opts down to “monthly”, will my flows still send to them? That depends on how you have configured your flows and your preference settings. If a subscriber asked for reduced frequency, you should honour it across both campaigns and flows, otherwise the reduced-cadence promise is broken and they will unsubscribe for real. Review flow audience filters to respect preference settings.

Can I see which preference people chose? This card reports the count of updates over time, not the breakdown by chosen option. For the individual choices, check a profile’s Activity in Klaviyo or the analytics on your preference-centre form. Use this card for the trend and Klaviyo’s profile view for the detail.
