Is Facteur cheaper than Mailtrap?

It depends on what limits you. At high test volume across few inboxes, their tiers are competitive. As soon as you need many inboxes, or SAML SSO, our grid separates the two: inboxes are unlimited from €39 a month and SSO is included at that same tier.

Can you migrate from Mailtrap to Facteur?

Yes, and most of the work is replacing the test SMTP address and the API endpoint in your tests. Messages already received there are not transferred: they are test data, and they regenerate on your suite’s next run.

Does Facteur send transactional mail like Mailtrap?

No. We receive test mail and stop there. If you need both a production sending service and a testing sandbox, Mailtrap covers both and we cover one.

Where is the test data hosted?

In France, at OVHcloud, and billing is in euros. The sub-processor register and the DPA are published on the site, without having to ask for them.

Facteur vs Mailtrap

Comparison

Facteur or Mailtrap: which should you pick?

Mailtrap covers both testing and transactional sending: if you want one vendor for both, theirs is the one to take.

Facteur only does testing, and prices features separately from volume — unlimited inboxes and SAML SSO from the middle plan, hosted in France and billed in euros.

Where they differ

	Facteur	Mailtrap
Inboxes	Unlimited from the Team plan	Sandbox count set by the plan
SAML SSO	Included from the Team plan	Reserved for higher plans
Message volume	Bought separately, in stacking packs	Set by the subscription tier
Per-inbox quotas	Yes, with overage alerts	Not documented
Transactional sending	No — we only receive	Yes, a dedicated product
Hosting	France, billed in euros	Outside France, billed in dollars
DPA	Downloadable online	On request

What Mailtrap does better

They also send. Their Email API/SMTP product carries production mail, where we stop at test reception. One contract, one vendor, one invoice.
It is a mature, widely adopted product, with the integrations and documentation that follow from that. We are starting out.
Their entry tier includes more test volume than our free plan, if that is all you need.

Choose Mailtrap if…

You want a single vendor to both test and send your production mail, or you would rather have a product that has been in place for years than a recent one. Both are good reasons, and we have nothing to say against them.

Choose Facteur if…

The number of inboxes limits you more than the volume, if SSO should not cost a change of tier, or if European hosting and a DPA you can sign without talking to sales are among your constraints.
