Amazon SES alternative for teams that want an email product

Amazon SES is strong when you want a low-cost AWS email primitive. Postscale is for product teams that want transactional email, SMTP relay, parsed inbound webhooks, suppressions, warming, delivery events, and one dashboard without assembling SNS, Lambda, S3, IAM, and custom parsers.

What to check in an Amazon SES alternative

An Amazon SES alternative search is usually not about beating SES on raw unit price. It is about deciding whether the team should keep operating email as AWS infrastructure or move product email to a provider that bundles the surrounding workflow.

Product surface or infrastructure primitive

SES gives you low-level sending. A complete alternative should include logs, suppressions, delivery events, inbound parsing, attachment handling, and operational controls.

Real cost at your workflow shape

Raw outbound price is only one line. Model inbound mail, attachments, validation, SNS/S3/Lambda, engineering ownership, observability, and support handoffs.

Inbound email complexity

If your SES setup uses receipt rules, S3, SNS, Lambda, and custom parsers, compare the maintenance cost against a provider with parsed inbound webhooks built in.

Migration path

A practical migration keeps SES live, verifies Postscale DNS, moves SMTP or REST calls behind an adapter, imports suppressions, and replaces receipt-rule chains gradually.

Why teams switch from Amazon SES

One email product, not several AWS services

SES setups often grow into IAM policies, SNS topics, Lambda handlers, S3 buckets, CloudWatch dashboards, and custom parsers. Postscale puts sending, receiving, delivery events, and suppressions behind one API key.

Parsed inbound without receipt-rule plumbing

Postscale receives inbound mail, parses MIME, stores attachments, and sends signed webhooks. You do not need to assemble SES receipt rules, S3 object handling, SNS fanout, and Lambda retry behavior yourself.

Operational controls built for product teams

Domain authentication, suppression imports, sender warming, per-domain activity, delivery events, and abuse controls are built into the product instead of infrastructure you have to compose.

EU-operated service with documented safeguards

Postscale is operated by DNScale OÜ in Estonia. Primary production service data is hosted in the EU/EEA, with documented transfer safeguards for limited infrastructure metadata where required.

Side-by-side comparison

SES is usually cheaper on raw outbound delivery. Postscale competes on the complete product surface around transactional email: migration speed, inbound parsing, suppressions, delivery visibility, and operating overhead.

Feature	Postscale	Amazon SES
Best fit	Product teams that want one email API and dashboard	AWS teams that want a low-level email primitive
Raw outbound unit cost	Bundled plans from EUR 9/mo; not positioned as the cheapest raw pipe	AWS list price starts around $0.10 per 1,000 outbound emails, with separate data and feature charges
REST email API	POST /v1/send with shared logs, suppressions, and webhooks	SES v2 SendEmail and SendRawEmail APIs
SMTP relay	Built for app migrations and legacy systems	Supported through SES SMTP interface
Production access	Self-serve product onboarding with plan limits	New SES accounts start in sandbox and must request production access
Parsed inbound webhooks	Built in: parsed bodies, headers, metadata, and attachments	Receipt rules plus actions such as S3, SNS, Lambda, or WorkMail
Attachment handling	Stored with authenticated download URLs	Usually S3 storage plus application retrieval code
Delivery events	Signed webhooks for delivered, bounced, deferred, complained, and related events	Event publishing can be routed through AWS destinations
Suppression management	Dashboard, API, CSV import, and fail-fast send checks	Account-level suppression list with SES APIs after production access
Warming controls	Domain and ISP-aware workflows in the product	Mostly self-managed through sending behavior and quotas
Masked email addresses	Yes (Shield)	No native equivalent
XRechnung / e-invoicing	Yes (EU mandate ready)	No native equivalent

Pricing comparison: model the whole SES workflow

Use SES as the raw-cost benchmark, then add the operational pieces your application actually needs. These examples are planning models, not a promise that one provider is always cheaper.

Scenario	Amazon SES	Postscale	Planning note
10,000 outbound transactional emails/month	Roughly $1.00 in SES outbound delivery before data transfer, attachments, validation, or surrounding AWS services.	Starter includes 10,000 shared send + receive emails/month at EUR 9/mo.	SES wins raw send price. Postscale bundles logs, webhooks, suppressions, inbound evaluation, and product UI.
100,000 outbound emails/month	Roughly $10.00 in SES outbound delivery before surrounding charges.	Pro includes 100,000 shared send + receive emails/month at EUR 79/mo.	Use Postscale when engineering ownership and support workflows matter more than raw delivery cost.
Inbound email with attachments	SES receiving is charged separately and receipt-rule designs often add S3, SNS, Lambda, KMS, and parser maintenance.	Inbound messages count toward the shared plan quota and arrive as parsed signed webhooks.	This is where a complete product can be simpler than a low-level primitive.
Migration from existing SMTP apps	Supported, but production access, credentials, limits, event publishing, and suppressions remain AWS-side concerns.	SMTP relay and REST sends share the same dashboard, suppression checks, and webhook stream.	Start with SMTP for low-risk cutover, then move new code to REST.

API migration example: SES v2 to Postscale

The safest migration puts email behind a small adapter. Start by mapping one template or transactional workflow, then route a small percentage of production traffic through Postscale.

Amazon SES v2

import { SESv2Client, SendEmailCommand } from "@aws-sdk/client-sesv2";

const ses = new SESv2Client({ region: "eu-central-1" });

await ses.send(new SendEmailCommand({
  FromEmailAddress: "Acme <alerts@example.com>",
  Destination: { ToAddresses: ["user@example.com"] },
  Content: {
    Simple: {
      Subject: { Data: "Welcome" },
      Body: { Html: { Data: "<p>Hello from Acme</p>" } },
    },
  },
}));

Postscale REST API

await fetch("https://api.postscale.io/v1/send", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.POSTSCALE_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <alerts@example.com>",
    to: ["user@example.com"],
    subject: "Welcome",
    html_body: "<p>Hello from Acme</p>",
    tags: ["onboarding"],
  }),
});

Deliverability differences that matter during an SES migration

Deliverability is not transferred by changing an API key. Preserve authentication, suppressions, recipient quality, and ramp discipline while you compare providers.

Sandbox and quota planning

New SES accounts start in sandbox with tight sending restrictions. Postscale plans use product limits, but a high-volume migration still needs a deliberate ramp and monitoring window.

Domain authentication

Publish Postscale DKIM, SPF, return-path, and DMARC-compatible records beside SES records before routing production traffic. Remove old records only after the cutover has settled.

Suppression continuity

Export SES account-level suppressed destinations by reason and import them before first production sends. Missing suppressions can recreate bounces and complaints you already learned from.

Inbound and reply visibility

SES receipt rules can hand off raw messages to AWS services. Postscale delivers parsed inbound webhooks, so support replies, bounces, and email-driven workflows are visible in one product surface.

EU hosting and compliance proof points

Use these checks when comparing EU email API alternatives. Server location matters, but so do processor agreements, subprocessors, retention, and the entity operating the service.

Operating entity

Postscale is operated by DNScale OÜ in Estonia, EU.

Primary service data

Primary production service data is hosted in the EU/EEA, with documented safeguards for limited infrastructure metadata where required.

Processor paperwork

A standard GDPR DPA is available for vendor review. Open DPA

Subprocessors

Current subprocessors and safeguards are published. Review subprocessors

Privacy documentation

Frequently asked questions

What is the best Amazon SES alternative?

The best fit depends on why you are leaving SES. If you want the lowest raw outbound cost and already operate AWS comfortably, SES is hard to beat. Postscale is a strong fit when you need REST sending, SMTP relay, parsed inbound webhooks, suppressions, warming, and EU/EEA-hosted primary service data in one email product.

Is Postscale cheaper than Amazon SES?

No, not on raw outbound unit price. SES is the right baseline if you want a low-cost infrastructure primitive and are comfortable operating the surrounding AWS pieces. Postscale is priced for a complete product surface that includes sending, inbound, suppressions, webhooks, warming, and operational UI.

Can I move SMTP traffic before changing API code?

Yes. Applications that already speak SMTP can switch host, username, and password first. REST sends can move later through a small adapter layer.

What replaces SES receipt rules?

Postscale inbound aliases and rules replace the usual S3, SNS, and Lambda chain. Your app receives parsed JSON webhooks with authenticated attachment download links.

What replaces SES event publishing?

Postscale delivery events are delivered as signed webhooks for accepted, delivered, bounced, deferred, complained, and related lifecycle events. Your app can handle one webhook stream instead of wiring SES destinations through AWS services.

Can I migrate SES suppressions?

Yes. Export account-level suppressed destinations, preserve bounce or complaint reasons, preview the CSV in Postscale, and import before production traffic moves.

Do I need to change DNS when moving from SES?

Yes. Add Postscale domain verification, DKIM, SPF, and return-path records while leaving SES records in place. After both systems authenticate correctly and Postscale traffic is stable, remove stale SES records deliberately.

How should I compare SES deliverability with Postscale?

Compare the same stream, sender domain, recipient quality, template, and volume ramp. Differences during a migration are often caused by suppressions, authentication, recipient mix, or ramp speed rather than the API provider alone.

Can I keep AWS for hosting and use Postscale for email?

Yes. Many teams keep their application on AWS while moving email workflows to a dedicated provider. The integration boundary is just SMTP credentials or a REST send call plus webhooks.

When should I stay on Amazon SES?

Stay on SES when raw outbound price is the main requirement, your team already owns AWS operations, and you are comfortable maintaining event routing, inbound parsing, monitoring, suppressions, and deliverability controls yourself.
