So Tell Us Review 2026: An Honest Look at the Family Letter App

Table of Contents

What Is So Tell Us?

So Tell Us is a private, recurring email letter for small groups — up to five people. Every few weeks, a handful of warm questions land in everyone's inbox. Each person answers when they have a moment: a sentence, a photo, or a voice note. On a fixed send day, one compiled letter arrives with all the answers inside.

No app. No feed. No notifications. The email is the only touchpoint, and that is entirely intentional.

It is built by a solo founder in Munich and hosted in Germany. The English version lives at so-tell-us.com, with a German version at erzaehl-doch-mal.com.

This review covers what the product actually does, who it suits, where it falls short, and how it compares to the alternatives most people reach for first.

How It Works

Setup takes about two minutes. One person starts a group, invites up to four others by email, and picks a send cadence. Everyone else just needs an email address — no account creation, no install.

Every few weeks, three to five questions arrive. They are warm and specific: the kind that make you pause before answering. Something that made you laugh this week. What you are looking forward to. What has been sitting on your mind that you have not quite said out loud yet.

Each person replies when they have time. One sentence is enough. Skipping a round is fine too.

On the send day, one letter arrives with all the answers gathered together. It reads like a real letter — not a thread, not a feed. Nothing pings. Nothing pushes.

Key Features

Recurring Question Prompts

The questions are the engine. They arrive pre-written, so no one has to think of something to say or find the energy to initiate. Three to five questions land every few weeks — often enough to feel like a rhythm, infrequent enough that it never feels like a chore.

This is what separates So Tell Us from a group email chain. Nobody has to start the conversation. Nobody has to figure out what to ask. The cadence runs itself.

Three Ways to Reply

You can reply with plain text, a photo, or a voice note. That range matters more than it might seem at first.

Some people write naturally. Others find a voice note easier when they are in the car or out for a walk. A photo works when words feel like too much. The format is personal, and no one in the group has to use the same one.

The Compiled Letter

All the answers come back as one letter — not as separate replies scattered across a thread. You read what your sister wrote, then your mum, then your old flatmate, all in one sitting on one page.

That compilation is the heart of the product. It creates a shared moment even when everyone answered at different times, in different time zones, on different days.

Voice Note Transcription

Voice notes are automatically transcribed so they read naturally inside the letter. The recipient does not need to press play — the words are already there. But the original recording is still available if they want to hear it.

No comparable product offers voice notes as a first-class reply format. For older family members who find typing uncomfortable, this alone can change who is actually able to participate.

Zero-Notification Design

No push notifications. No streaks. No likes. No read receipts. The email arrives on a fixed schedule you already know about, and then it leaves you alone.

If you are worn down by products that compete for your attention, this one does the opposite. It asks for your attention once, on a day you expect, and that is it.

Privacy and Hosting

Servers are in Germany. All subprocessors are EU-based. No ad tracking runs inside the authenticated app. Letters are never used to train AI — the only AI in the system handles voice transcription, and it does not retain your content.

For a group sharing real, private details about their lives, this is worth knowing. The product is not monetised through your data.

What It Costs

€5 per month for the whole group. One person pays and invites up to four others. Everyone else joins at no cost.

There is a 14-day free trial with no credit card required. Cancel anytime in two clicks.

For groups larger than five, the founder is available to discuss a custom arrangement directly.

Who It Works Best For

So Tell Us suits people who already sense that group chats are not quite doing the job. The messages are there. The real conversations are not.

It works especially well for:

  • Families spread across cities or countries. Because the whole product runs through email, a parent in their 60s who has never touched a social platform can participate just as easily as anyone else.
  • Close friend groups who have drifted into infrequent contact. The structured questions give everyone something to respond to, without anyone needing to carry the conversation forward.
  • People who want intentional contact rather than reactive contact. The fixed cadence and no-notification design suits those who have already started stepping back from always-on communication.

The five-person cap is a feature, not a constraint. It keeps the letter intimate. You are reading five people's answers, not fifteen.

What It Does Not Do

It is worth being honest about what So Tell Us is not built for.

It is not a messaging tool. There is no back-and-forth conversation inside it. If someone shares something in a letter and you want to respond directly, that happens separately — by phone, text, or email.

It is not designed for large groups. Five is the limit on the standard plan.

There is no mobile app, which is a deliberate choice — but it does mean the experience lives entirely in your inbox. If your inbox is chaotic, the letter can get buried.

The questions are pre-written and sent by the platform. If you want full control over what gets asked each round, that is not how the current product works.

How It Compares to Alternatives

Question prompts Yes Yes No No
Compiled letter Yes Yes No No

Letterloop is the closest comparison. It also sends questions and compiles answers into a shared letter. But it requires a mobile app, which brings push notifications and app-store friction with it. Its pricing is freemium with in-app purchases that are not transparently listed. So Tell Us has a flat, clear price and nothing to install.

Marco Polo is video-based async messaging. It requires an app, runs as a feed with notifications, and has no structured prompts or compiled digest. It is a different product for a different purpose.

Groups.io is built for clubs and organisations. No question prompts, no compiled digest, no fixed send-day cadence. It was not designed for intimate small-group storytelling.

Honest Verdict

So Tell Us does one thing and does it well. It creates a recurring, structured moment for a small group of people to share real life with each other — without requiring anyone to initiate, schedule, or manage a conversation.

The email-only, no-app approach will not suit everyone. But for someone who is tired of group chats that feel busy without feeling close, it is a genuinely considered alternative.

The €5 flat price for the whole group is fair. The privacy setup is thoughtful and verifiable. The voice note feature is something no comparable product offers.

The best summary of what it actually does comes from someone who uses it: "Since we started, every phone call begins differently." — Anna, Düsseldorf. That is a small thing. It is also not a small thing at all.

FAQs

What is So Tell Us and how does it work?
So Tell Us is a private email letter for groups of up to five people. Every few weeks, three to five questions arrive in everyone's inbox. Each person replies in their own time — with text, a photo, or a voice note. On a fixed send day, one compiled letter arrives with all the answers inside.

Does So Tell Us require an app?
No. It works entirely through email. Recipients do not need to create an account or install anything — an email address is all it takes to participate.

How much does So Tell Us cost?
€5 per month for the whole group of up to five people. One person pays; the others join for free. There is a 14-day free trial with no credit card required.

Is So Tell Us private?
Yes. Letters are never visible outside the group. Servers are in Germany, all subprocessors are EU-based, there is no ad tracking inside the app, and letters are never used to train AI.

How is So Tell Us different from Letterloop?
Both send questions to a private group and compile the answers into a shared letter. The main differences: So Tell Us requires no mobile app, has a flat transparent price, supports voice note replies (which Letterloop does not), and is hosted in the EU.

Can older or less tech-comfortable family members use it?
Yes. Because the product works entirely through email and recipients do not need to create an account, it is accessible to people who do not use social platforms or smartphones comfortably.

What happens if someone misses a round?
Skipping is fine. There are no streaks, no reminders, no penalties. The letter goes out on the send day with whatever answers arrived. One sentence is genuinely enough when someone does participate.

So Tell Us is a quiet product in a noisy category. If what you have read here sounds like something your family or a close group of friends might actually use, you can start a 14-day free trial at so-tell-us.com.
