Comparison
YourMail vs Postmark
Of everything in this category, Postmark is the product YourMail is most like — transactional only, suppression treated as non-optional, no marketing platform bolted on the side. That makes this the least dramatic comparison on the site and the most useful one, because the remaining differences are narrow and several of them are theirs.
Side by side
No prices for Postmark on this page. They change, and a stale price on a page that benefits us is the most common way a comparison misleads — check their pricing directly. Ours is on our pricing page.
| YourMail | Postmark | |
|---|---|---|
| Product scope | Transactional sending only. No campaigns, no audiences, no template designer. | Transactional sending, with a separate broadcast product alongside it. The transactional side is held to the same discipline as ours and has been for far longer. |
| Where mail is sent from | London (eu-west-2), on AWS SES — the region the code configures and the region visible in the headers of mail you receive. | Their own infrastructure, with an EU sending option available. Check their documentation for the current regional position rather than our summary of it; note that after Brexit an EU region and a UK one answer different questions. |
| What is claimed about data residency | Sending is in the UK — London (eu-west-2), on AWS SES: it is the region the code configures and it is visible in the headers of mail you receive, so it is checkable rather than asserted. Storage residency at rest is not claimed, because we do not have it in writing from our database provider. Stated on the page rather than left for a reviewer to discover. | An established compliance surface with more certifications behind it than we have. Read their own documentation for the specifics. |
| Deliverability track record | New. Built on SES with a circuit breaker, per-tenant reputation grading and a new-account ramp — but the record itself is short, and a short record is a short record. | The strongest reputation in this category, earned over more than a decade, with public delivery-time reporting. This is the row where the gap is widest and it is not close. |
| Templates | React components in your own codebase, via the optional react-email integration. No hosted editor. | A hosted template system with a layout model and a library of well-designed starting points, editable by someone who does not write code. |
| Managed unsubscribe | RFC 8058 one-click List-Unsubscribe injected and enforced on sends marked bulk, with the suppression scoped so an unsubscribe blocks bulk mail and never blocks a password reset. | Suppression streams that separate transactional from broadcast, which is the same distinction reached by a different route. |
| Support | The founder, by email, from a dashboard ticket. Fast in practice, and a single point of failure by definition. | A real support organisation with published response expectations and people who have seen your problem before. |
Where Postmark is the better choice
Written by us, about a competitor, on our own site — so treat it as a starting point and not an audit. It is here because a comparison with nothing in this section is not a comparison.
Deliverability record
More than a decade of it, publicly reported delivery times, and a reputation in this category that is close to unmatched. We are built on SES with sensible controls around it, which is a design and not a record. If deliverability is the single thing you are optimising for and you have no UK constraint, this alone is a good reason to pick them.
Hosted templates
A layout model, a library of well-made starting points, and an editor a designer or a marketer can use without opening a pull request. We deliberately have none of this — templates live in your codebase — and for a team where email content is not written by engineers that is a real cost.
Support that is not one person
A support organisation with published expectations, out-of-hours coverage and people who have already seen the problem you are about to hit. Our support is the founder answering email, which is fast right up until it is not available.
The narrow case for switching
Most teams reading this should stay where they are, and a comparison page that would not say so is not worth reading. The case for moving is specific: a customer's security review has asked where mail is sent from and wants a checkable answer, or you are selling into UK public sector, healthcare or financial services and a reviewer expects the position written down rather than inferred from a region list.
If that is you, the UK versus EU residency page sets out why an EU region is not automatically a UK answer, and the DPIA page is written for the person filling in the assessment. If it is not you, weigh the rows above and expect Postmark to win several of them.
Common questions
Is YourMail trying to be a Postmark alternative?
In scope, yes — both are transactional-only products that refuse to bolt on a marketing platform. In maturity, no, and it would be silly to claim otherwise: Postmark has more than a decade of delivery record and publishes its delivery times. The narrower reason to pick YourMail is that mail is sent from London and the compliance position is written down in specific terms, including the parts that are not claimed.
Does Postmark send from the UK?
Postmark offers an EU sending option; check their own documentation for the current regional position. The distinction that matters for a UK reviewer is that after Brexit the UK and the EU are separate jurisdictions, so an EU region does not by itself answer a UK residency question. YourMail sends from London (eu-west-2), which is checkable in the headers of any message you receive.
What about templates — do I have to write my own?
With YourMail, yes: templates are React components in your codebase, sent via the optional react-email integration. There is no hosted editor and none is planned. Postmark's hosted template system is genuinely good and is editable by someone who does not write code, so if that matters to your team it is a decisive difference in their favour.
Can I migrate a suppression list from Postmark?
Yes, and you should before your first send. Export the addresses Postmark has suppressed and import them through POST /v1/suppressions — starting anywhere new with an empty list means re-mailing every address that has already bounced or complained, which is the fastest way to damage a new sending reputation.
