Amazon SES alternative
An Amazon SES alternative with batteries included
Amazon SES is cheap raw infrastructure, but you assemble everything else — suppression logic, dashboards, templates, mailboxes — yourself, on US-owned cloud. PostStack gives you the full platform on EU infrastructure, with pricing that stays predictable as you grow.
Why teams pick PostStack over Amazon SES
A platform, not a primitive
SES gives you an SMTP/API pipe and little else — open/click tracking, suppression UI, templates, broadcasts, and dashboards are all DIY. PostStack ships all of it, so a small team is productive on day one instead of building plumbing.
EU infrastructure, not US-owned cloud
SES runs on AWS; even the eu-regions are operated by a US company subject to the CLOUD Act. PostStack is a Danish company on dedicated infrastructure in Helsinki — sovereignty by default, not a region toggle on a US provider.
Predictable pricing with support
SES is $0.10/1,000 emails but support is a paid AWS plan and deliverability is your problem. PostStack bundles reputation monitoring, warmup, and human support into flat per-tier pricing.
IMAP mailboxes + inbound
SES inbound drops mail into S3 for you to process. PostStack ships real IMAP/POP3 mailboxes, webmail, and inbound webhooks on the same domain.

Stay on Amazon SES if…
Stay on Amazon SES if you have engineering capacity to build the platform layer, want the lowest possible per-email cost at very high volume, and are already all-in on AWS.
Switch to PostStack if…
Switch to PostStack if you want the full email platform out of the box, EU sovereignty without a US hyperscaler, and a bill that does not require AWS expertise to predict.
Frequently asked questions
Is PostStack more expensive than Amazon SES?
On raw per-email cost, SES is cheaper. But SES is just the pipe — you build tracking, suppressions, templates, dashboards, and deliverability monitoring yourself, and pay separately for support. PostStack bundles the whole platform, so the real comparison is SES-plus-your-engineering-time versus a flat PostStack tier.
Does PostStack run on AWS?
No. PostStack runs on its own dedicated infrastructure in Helsinki, Finland, operated by a Danish company. There is no US hyperscaler in the data path, so it sidesteps the CLOUD Act exposure that comes with AWS, even in EU regions.
Can PostStack handle high volume like SES?
Yes. PostStack runs Postfix with dedicated-IP warmup and per-domain reputation tracking. The Scale tier covers 100,000/month and overage is €0.25/1,000 beyond that, so 1,000,000/month is €255 — flat and predictable.
