The decisive criterion when comparing posthumous message services is how the service learns of the user's death. Three models coexist in 2026: declaration by a relative with supporting documents (Postumo), activation by designated trusted persons (Post Scriptum, Akhacia — formerly In-Memory), and automatic inactivity detection, known as a dead man's switch. Only the latter guarantees that messages are sent without depending on a relative taking action: in the panel compared, Hugete is the only service offering it, backed by human validation (HugGuard). FutureMe, for its part, delivers letters to your future self on a chosen date but has no posthumous feature at all.
Choosing a posthumous message service means entrusting your final words to a third party — and betting that this third party will know, when the time comes, that you are no longer here. This comparison reviews five services frequently mentioned in searches about the posthumous message: Post Scriptum, Akhacia (formerly In-Memory), Postumo, FutureMe and Hugete. Note that this panel is mostly French and European — the market for posthumous delivery is currently led by French companies, with FutureMe as the long-standing American outlier. Each service has a different positioning — legal legacy, encrypted mobile app, administrative support, letters to yourself, guaranteed delivery — and none covers everything. The goal of this page is not to crown a universal "winner", but to help you identify the service that matches your actual need.

Criterion #1: how does the service learn of your death?
Before formats, pricing or design, one question conditions everything else: through which mechanism will the service know that you have died? The entire promise depends on this link in the chain — a posthumous message that never leaves has served no purpose. Three models coexist on the market:
- Declaration by a relative: a family member contacts the service with supporting documents (death certificate, ID). This is Postumo's model. Reliable in terms of verification, but it assumes your relatives know the service exists, know you had an account there, and take the step — at a time when they have a thousand other things to handle.
- Designated trusted persons: you name one or more contacts in advance whose role is to notify the service. Post Scriptum lets you designate up to five; Akhacia calls them "confidants". This is more robust than a simple declaration, because these people know their role in advance. But the structural limit remains: if none of them acts — oversight, simultaneous death, estrangement, lost contact — nothing is ever sent.
- Automatic inactivity detection (the "dead man's switch"): the service sends you regular check-in reminders; as long as you respond, nothing happens; if you stop responding, the delivery process starts on its own. It is the only model that does not depend on any outside initiative. In the panel compared, only Hugete offers it (HugVeille), adding a human safeguard: a trusted contact (HugGuard) confirms or blocks delivery within 48 hours, without ever accessing the content of the messages.
This point deserves to be stated calmly: with every service in the panel except Hugete, if nobody notifies the service, the messages are never sent. This is not a design flaw — it is a scope choice, often consistent with the rest of the offering — but it is the first criterion to check before subscribing.

Who is each service the best choice for?
Post Scriptum: if the legal and notarial side matters most
Post Scriptum (Post Scriptum SAS, Bordeaux, a recent company) organises digital legacy into four modules: posthumous messages, a guided will and directives (PS Volontés), an encrypted vault, and — unique in this panel — notary consultations by video call (PS Notaire). Its other strong point is infrastructure: hosting in France, AES-256 encryption and HDS certification (the French health-data hosting standard), a rare level of rigour in this market. As for scope: no fixed-date messages, rich formats (video, audio) not publicly confirmed, a French-only interface, and a trigger that relies on up to five trusted persons — no inactivity detection. Pricing: first message free (50 MB), Complet plan at €3.99/month (10 GB, unlimited messages), or Sérénité at €249 as a one-time payment. The best choice if you want your messages backed by genuine legal and notarial support.
Akhacia (formerly In-Memory): if end-to-end encryption and a mobile app come first
Launched in November 2024 under the name In-Memory (In-memory SAS, Paris), the app is now called Akhacia — in-memory.fr redirects to akhacia.com. It is a mobile app for posthumous messages and messages for future key dates, with the widest range of formats in the panel (text, video, image, audio, PDF) plus advance directives. Its central argument is claimed end-to-end encryption — "we know nothing about the content of the messages" — the strongest confidentiality promise in the panel, although it has not been publicly audited. The trigger relies on "confidants" who notify the app of the death; the verification process is not publicly documented, and there is no inactivity detection. Pricing: free Basic (1 message, 1 attachment), Standard €1.99/month (5 messages, 300 MB), Premium €6.99/month (6 GB), Gold €149.99 one-time (unlimited). Hosted at OVH in France, interface in four languages (FR, EN, DE, ES). The best choice if end-to-end encryption and a fully mobile experience are your priorities.
Postumo: if post-death administrative support comes first
Postumo (a French company founded by Julien and Franck Ridon) approaches the subject from another angle: it is not primarily a messaging service, but a vault of "life data" (more than twenty categories) combined with administrative support for relatives after the death — detection of financial aid the family is entitled to, help with formalities, with support for 24 months. No other service in the panel offers this. Personal messages exist but remain basic: no posthumous video or audio put forward, no fixed-date messages. The trigger is a relative contacting the service with supporting documents. On the security side: hosting in France, AES-256 and two-factor authentication. Pricing: Sérénité at €49/year, or Essentielle at €199 one-time (the post-death package). The best choice if your priority is easing the administrative burden of those who remain, more than passing on intimate messages.
FutureMe: if you are writing to yourself, not to your loved ones
FutureMe (futureme.org, an American service created in 2002) is the elder of the panel: more than 20 million letters sent in 24 years. Its principle differs from all the others: you write a letter to your future self, delivered by email on the date of your choice, up to 2076. Its scope must be stated clearly: FutureMe offers no posthumous feature and no death detection — that is simply not what it does. The service moved to a paid freemium model in 2025 (limited free version, with ads), the interface is mainly in English, and neither the hosting location nor GDPR compliance is communicated. Its strength lies elsewhere: 24 years of track record, a longevity no recent service can claim. The best choice if you are looking for a ritual of writing to yourself. If you are weighing the two approaches, read our detailed comparison with FutureMe.
Hugete: if the guarantee that the message leaves matters most
Hugete combines posthumous messages and fixed-date messages with recurrence, in text, photo, video and audio — the principle of the digital time capsule. Its singularity rests on three points. First, it is the only service in the panel with automatic inactivity detection (HugVeille, a dead man's switch): delivery does not depend on any action by a relative, and a human safeguard (HugGuard) confirms or blocks within 48 hours, without ever accessing the content. Second, reception is the simplest in the panel: a private link (HugBox), valid for 12 months, with no account or app to install. Third, blockchain certification (HugCert, on Polygon) provides time-stamped proof of a message's creation date — unique in this comparison. Hosting is in Germany (Hetzner, EU), GDPR-compliant — details on the security page —, the interface exists in three languages (FR, EN, ES) and the free plan is genuinely usable: 2 posthumous messages, 2 loved ones, watch and trusted contact included (see pricing).
In all honesty, its limits compared with the others: Hugete offers neither a legal or notarial module (that is Post Scriptum's ground), nor claimed end-to-end encryption (that is Akhacia's argument), nor post-death administrative support (that is Postumo's), nor a native mobile app, and its track record is short compared with FutureMe's 24 years. The best choice if you want the certainty that your messages will leave even if nobody notifies the service, frictionless reception for your loved ones and proof of date.
How to choose: four questions to ask yourself
Rather than a ranking, four questions are enough to decide:
- 1. Who will have to notify the service? If the answer "nobody should have to" feels like the only acceptable one, you need inactivity detection — Hugete in this panel. If you have reliable, informed relatives, the models of Post Scriptum, Akhacia or Postumo may suit you.
- 2. What do you want to pass on? Words and memories (messages, videos), legal wishes (see also our digital will page: none of these services replaces a will), or an administrative file to relieve your loved ones?
- 3. What will the recipient have to do? Create an account, install an app, or simply open a link? When the day comes, every point of friction counts.
- 4. Where is your data, and for how long? EU hosting and GDPR, a lasting free tier or a one-time payment, proof of date: check what matters to you before entrusting your final words.
More detailed answers await in our FAQ. And whichever service you choose, the most important thing remains the same: that your words exist, and that they arrive.
Frequently asked questions
Which is the only service that sends messages without a relative notifying it?
In the panel compared (Post Scriptum, Akhacia — formerly In-Memory, Postumo, FutureMe, Hugete), Hugete is the only service with automatic inactivity detection (HugVeille, a dead man's switch): if you stop responding to check-in reminders, delivery starts on its own, after verification by your trusted contact (HugGuard) and a 48-hour safety delay. With Post Scriptum, Akhacia and Postumo, a relative or trusted person must notify the service; FutureMe has no posthumous feature at all.
What is the difference between a trusted person and a dead man's switch?
A trusted person is a human trigger: you designate one or more relatives whose role is to notify the service of your death. If none of them acts — oversight, lost contact, simultaneous death — nothing is sent. A dead man's switch (inactivity detection) is an automatic trigger: the service sends you regular check-in reminders and, if you stop responding, delivery starts without depending on anyone. Hugete combines the two: the automatic watch triggers, and a trusted contact confirms or blocks, without accessing the content.
Do these services replace a will?
No, none of them does. A posthumous message is private correspondence with no legal force: it cannot organise your estate or distribute your assets. For that, a legally valid will remains necessary — Post Scriptum does offer video-call notary consultations, and our page dedicated to the digital will explains how to articulate the two. These services pass on the intimate (words, memories, emotional guidance); the will settles the legal side. The two are complementary.
What happens if the service shuts down before my death?
It is a real risk to consider for any service of this kind, as most are young companies. Good practices: check that you can export your content at any time, keep a local copy of your essential messages, favour services whose free tier or one-time payment does not lock in your data, and tell a relative which service you use. A serious service should also provide, in its terms, for notice and data restitution in the event of closure.
Can you use several services at the same time?
Yes, and it is sometimes the best answer, since their scopes barely overlap: nothing prevents you from entrusting your relatives' administrative support to Postumo, notarial consultations to Post Scriptum, and your posthumous messages to a service with inactivity detection such as Hugete. Simply keep the whole consistent (same recipients, same wishes) and avoid stacking more subscriptions than you will actually maintain over time.
