Pricing
The subscription pays for features. Volume is bought separately.
This is the one design choice that really matters: raising your capacity must never commit you to a higher monthly tier.

Operations used
One email received is one operation. SMS are paid for separately and do not count here.

The unit
1 email received = 1 operation
Your plan includes a number of operations a month. Looking at your messages never eats into it: call the API as often as you like, read one message a hundred times, wait thirty seconds for it to arrive, and the counter will not move.
The rule fits in one sentence: you pay when a message arrives, or when it gets duplicated. Never when you read it.

What uses your operations quota

- A full copy of the message in a second inboxsoon1 operation
What uses none of it
- Reading a message, as many times as you like
- Waiting for a message to arrive, however long it takes
- An email refused because your quota ran out
- The first webhook sent for a messagesoon
- A pointer to a message that stays in its own inboxsoon
A test that receives 3 confirmation emails and reads them back 40 times to check their contents uses 3 operations. Not 43, and not 120.
Soon, a rule will be able to make a received message show up in a second inbox, to gather all your login codes in one place for instance. There are two ways to do that, and price is not the only difference. A pointer costs nothing, but it points at the original message: delete that message and the pointer goes with it. A copy costs one operation and gives you a genuine second version, which stays even if you delete the first.
Two things never touch this quota and are paid for separately. SMS first: they come with the phone number that receives them, and you watch them on a meter of their own. Then the space your attachments take up, which has its own limit in gigabytes.
Why talk about operations rather than simply emails? Because one number to watch beats three. The day you start using webhooks or copies, they will draw on this same quota, with no new limit to track and no new line on your bill. And if all you do is receive emails, which is the common case, nothing changes for you: your operations quota is your email count.

Capacity
Packs you buy when you need them
Valid twelve months, they stack, and you never lose one by changing plan. This is what replaces renegotiating a subscription at every spike.
| Pack | Price | Per 1,000 operations | Saving vs pay-as-you-go |
|---|---|---|---|
| 25 000 operations | 6 € | 0,22 € | −33 % |
| 100 000 operations | 18 € | 0,18 € | −45 % |
| 250 000 operations | 36 € | 0,14 € | −56 % |
| 500 000 operations | 62 € | 0,12 € | −62 % |
| 2 000 000 operations | 220 € | 0,11 € | −67 % |
| Pay-as-you-gono commitment | on usage | 0,33 € | baseline |
Spending cap
Set a maximum beyond which we stop billing and start refusing messages. Nobody should discover a bill.
Two clicks to buy
A pack is available the moment payment clears. No ticket, no salesperson, no waiting for next month.
Automatic top-up
Optional: buy the same pack again automatically when less than 20 % of credits remain, so a CI run is never interrupted.

How we build our comparisons
A price comparison nobody can verify is worth nothing. Here are our sources.
- 01Personal and Core plans: monthly prices read on 2026-08-11 from the public pricing API of mailosaur.com: $25 for 500 emails a day, $63 for 2,500. Their annual formula is cheaper; we compare against monthly billing.
- 02The 210,000-message point: a renewal amount actually observed on a Core account configured at 7,000 emails per day ($247.38/month).
- 03SMS module: “from $37.50 per month” on top.
A nuance that favours us, and that we would rather explain
Our comparison reasons at equal consumed volume. But most of our competitors price on a daily limit: you pay for the capacity you provision, not the one you use. Since a test suite has no steady throughput, you have to size for the peak so you are not blocked on a Tuesday morning.
Concretely, and at equal scope (email only, no SMS module on either side), consuming 150,000 emails a month with peaks means a limit of around 7,000 a day, billed at $247.38, close to €228. Equal-volume interpolation, meanwhile, gives €152. That last figure is the one we display: the most conservative, the one that flatters us least.
Between those reference points we interpolate linearly: it is an estimate, not a competitor quote. Other vendors change their prices without telling us; if you spot a discrepancy, write to us at hello@facteur.eu and we will correct this page.
Questions
What we get asked most
What happens if I exceed my capacity?
Nothing breaks, and you lose no message. If you bought credits, those are used first. Otherwise you pay as you go, 0,33 € per 1,000 operations, and never more than the maximum amount you set yourself. If you would rather not pay anything extra, you can decide, inbox by inbox, to turn messages away once the quota is reached. Attachment storage is a separate limit and behaves differently: when it is full your emails keep arriving as usual, but their attached files stop being kept. Each message then shows you the file name and the reason it was not kept.
Do my credits expire?
After twelve months. They stack, and changing plan, either way, costs you none of them.
Can I downgrade mid-month?
Yes, and it takes effect immediately, pro rata. Since capacity is bought separately, you do not need to move up a plan to absorb a spike in the first place.
Do emails and SMS share the same counter?
No, and that is deliberate: the two do not cost the same. A received email costs us almost nothing; a received SMS goes through a carrier and a number rented by the month. With one shared pool, one customer's SMS volume would eat into the quota paid for by those who only send email. So your subscription includes operations, of which a received email uses one, and each number brings its own SMS: 17 € per number per month, 100 inbound SMS included, then 0,015 € per SMS. The app shows you the two counters side by side.
Is SAML SSO really included from the Team plan?
Yes: SAML 2.0 and OIDC, with one identity provider per organisation, from €39 a month. Most of our competitors reserve this for an Enterprise plan on quotation. Automatic account provisioning and deprovisioning (SCIM) stays on the Business plan: that is where the need genuinely becomes a large-organisation one.
Is VAT included?
No, all displayed prices exclude tax. Applicable VAT is calculated automatically from your country and your EU VAT number.
How do I pay on invoice rather than by card?
SEPA direct debit is available on every paid plan. Purchase orders are offered from the Business plan.
What does the twelve-month commitment change?
It takes 20 % off what you pay, and you are still charged every month, exactly as on a subscription with no commitment: you never pay twelve months up front. In exchange you cannot move down a plan before the twelve months are up; moving up stays possible at any time.
