Souvenir: a year-in-review campaign kit you run in Claude

How user #3,107 gets their own numbers

A recap is one email with a different set of numbers for every person. The kit makes those numbers and the template that reads them, for the email tool you already use.

Export one CSV

One row per user with their activity for the year, from any analytics tool or database. Mixpanel and Postgres can connect directly instead.

Sample data: 6 of the 16 columns in the Northwind Notes export.
Stats for every user, and who gets what

It picks the stats worth sharing, computes them for each user, and writes a coverage report. Light users get a different recap, not a thin copy of a power user's.

592power users: ranks and their top stats

2,394regular users: totals and a persona

703light users: a persona and their firsts, no ranks

984no activity this year: what's new, no stat cards

Sample coverage report, Northwind Notes: 4,673 users in the send file. 4 test and internal accounts were removed first, and 323 users who opted out were left out of the send.

Import the file, paste the template

An import file keyed on your user IDs, with every line already filled for that user, and an email template in your tool's own merge tags.
```
<p>{{ person|lookup:'recap2026_email_body' }}</p>
{% if person|lookup:'recap2026_card1_headline' %}
  <h1>{{ person|lookup:'recap2026_card1_headline' }}</h1>
  <p>{{ person|lookup:'recap2026_card1_body' }}</p>
{% endif %}
```
Shortened from the Klaviyo template the kit wrote for the Northwind Notes sample. For Mateo, card 1 reads "5,139" and "notes written in Northwind Notes from Jan 1 to Nov 15, 2026". Braze, HubSpot, Customer.io and Iterable each get their own import file and a template in their own syntax: Liquid for Customer.io.

Your data can make a stat for almost anything. Few of them belong on a card.

The kit scores each candidate against rules drawn from recaps people shared, keeps the few worth a card, and tells you why each one made it.

Ranks only for the top 20%

A rank appears only on something a person would want to share, and only when they're in the top 20%. Everyone else gets a true claim of another kind: their rank in their own group, a rare habit, or how much they grew.

Sensitive data stays out

10 categories are filtered by default: health, reproductive, sexual, religious and political data, gambling, money trouble, precise location, bereavement, and activity that may belong to someone else in the household. Cancellations and refunds never get celebratory copy.

No rank over a small group

A rank needs at least 100 people behind it, so nobody can be picked out and no "top 1%" is a top 1 of 40.

Every number traces to a query

No stat is estimated or written by AI. Each one comes from a script, and the QA report blocks any number with no query behind it. Tap "How this number was made" on the sample to see one.

113 documented checks, built on 31 criteria and 16 failure patterns from documented recaps at Spotify, Duolingo, Raycast and others.

Playbooks for SaaS and consumer apps: the stats that work and the ones that backfire
Your first card, from your own data, in about 10 minutes

Computes them for every user

Every number comes from a script and a query, never typed by AI

A true claim for users outside the top 20%: their rank in their own group, a rare habit, how early they started
Separate recaps for power, regular, light and dormant users
Test, internal and API accounts removed before anything is ranked

Handles the users who logged in twice

A coverage report: who gets a full recap, who gets a lighter one, who gets a thank-you note, and why
A fallback for every stat a user is missing
No ranks over groups too small to mean anything

Keeps you out of trouble

10 sensitive categories filtered by default, and you can edit the list
Opted-out users dropped from the export
Card links that don't reveal user IDs
113 documented checks drawn from real recap failures, and a QA report that blocks a number with no query behind it, a broken card or a merge tag that would print blank

Your colours, fonts and logo from one small brand file, and a proof sheet you approve before the batch

On any other setup, one link file and a one-page brief for your engineer, with copy-paste code for web, iOS, Android and React Native
Story opens, completions and shares sent to your own analytics

Delivers through the email tool you already have

An import file for Braze, Klaviyo, HubSpot, Customer.io or Iterable, shaped to that tool's limits
A merge-tag email in your tool's own syntax, with a default for every field, so nobody gets "Hi ,"
Subject line, preheader, in-app copy and push copy
A step-by-step import guide for your tool
Your worst cases shown first: the longest name, a count of exactly 1, a missing stat

Harsh, who makes Souvenir

Licence terms

Pro: one brand. A freelancer building for clients buys one Pro per client brand, or buys Agency. Everything the kit makes for that brand (cards, emails, import files, copy) belongs to you.

Agency: unlimited client brands while you're subscribed. Nothing your client's users see carries Souvenir branding. Clients own what you make for them and keep it after you cancel. The kit itself stays with the agency: don't hand the kit files to a client or resell them. A client who wants to run it themselves buys Pro. Cancel any time and keep the edition you have; you stop getting new editions and the onboarding call.

Too late for December? Send it the first week of January.

Ship before Christmas, or send it the first week of January, when inboxes are quiet. "Your 2026, in review" in the first week of January reaches people after the holiday rush.

Who makes this

I'm Harsh. I make Souvenir on my own, from Bengaluru. The recaps people forward are the per-user ones, and most software teams can't make one: the agency quote starts at $2,999, and the engineer is busy in December.

So I built a kit that does it from your own export, in your own Claude account, with every number traceable. Questions go to me, not a support desk: harsh@sendsouvenir.com.

Before you buy

Our Claude isn't connected to our data.

Export one CSV of per-user activity. That's the default path.

Can I use it for clients?

Pro is one brand. Agency is unlimited clients, white-labeled, and clients own what you make for them. Agency also includes a data-handling note for your client's legal team.

Do you build it for us?

No. It's a product, made so you don't need the $2,999 agency.

How does each user get their own numbers?

The kit writes a per-user attribute file your email tool imports, plus the email template with merge tags and fallbacks for missing stats. The card images are files you put on any static host or storage bucket, at one URL. Before it renders them, the kit tells you how many files there will be and which host fits. If hosting slips, the email shows each card as text.

Which Claude plan do I need?

Claude Pro or above, with code execution turned on. On a Team or Enterprise plan, an admin can turn off code execution or skill uploads. If yours is blocked, use a personal Pro plan or Claude Code. Your data stays in whichever account you use.

Is it too late for this year?

Buy by Fri Nov 20 to send in December, or by Fri Dec 18 to send in the first week of January.

What if our data is messy or thin?

Light and dormant users get a different recap (persona and firsts, no ranks), and a coverage report shows exactly who gets what. A rank needs at least 100 users behind it; below that, rank cards turn off.

Our engineer could build this in two days.

If you have a warehouse and an engineer with two spare days in December, they could build the data part. The kit also does what they'd skip: which stats to show, copy for every tier, fallbacks for light users, the coverage report and the cards.

Can't we send a company-level recap, or a Canva template?

You can, and lots of companies do. A per-user recap is the one people forward, because it's about them. The sample cards above show both: the first is the company recap, the rest are per user.

What happens if I cancel Agency?

You keep the edition you have and can keep using it for clients. You stop getting new editions and the onboarding call.

Check your data before you buy

The readiness checklist tells you which recap stats your data supports today, and what's missing.

Privacy

Souvenir runs inside your own Claude account. Your users' data goes from your export to Claude and into your own files. It never reaches me, and the kit sends nothing home.

This site counts visits without cookies. The logo and colours you try above stay in your browser. If you ask for the checklist, Kit stores your email to send it. Fonts load from this site, not from a font service. Checkout runs on Lemon Squeezy.
