Looking for an AWS SES alternative?

SES is a cheap, reliable sending engine. But the moment you want a dashboard, a template editor, or logs you can search, you're building it yourself. Here's an honest look at your options — including where SES is still the right call.

Why teams start looking elsewhere

SES is great at cheap, reliable delivery. The friction shows up in everything around the send.

01

No real dashboard

SES is an API and a line on your AWS bill — no screen for browsing sends, opening a message, or seeing why one bounced. You wire up CloudWatch and SNS and build that view yourself.

02

Setup is a project

Before one email goes out: IAM users and policies, verified identities, a configuration set, and an SNS topic wired to a queue just to catch bounces.

03

Sandbox, then quota tickets

New accounts can only email verified addresses until a support ticket frees them. Raising your send limit is another ticket — usually right when you are growing.

The short version

Just the things that decide it — setup, tooling, deliverability, price. No 40-row feature matrix.

A quick, honest take on each

No tool wins for everyone — ours included. Here's where each one is strong and where it isn't.

Lettr

Our pick

SES-grade sending with the dashboard, editor, and logs already built in.

Great for: teams that want reliable API and SMTP sending without building the tooling around it.
Watch out: newer than the incumbents, and not the cheapest per email at very high volume.

AWS SES

The cheapest, most bare-bones sending engine there is.

Great for: huge volume, deep AWS-native integration, and teams happy to build their own tooling.
Watch out: no dashboard or editor, a sandbox to escape, and analytics that stop at CloudWatch.

SendGrid

A broad platform covering both transactional and marketing.

Great for: larger programs that want both kinds of email under one roof.
Watch out: pricier than SES, and the breadth can feel heavy for a simple transactional need.

Postmark

Fast, focused, transactional-only sending with strong deliverability.

Great for: speed-obsessed transactional teams with no marketing email to send.
Watch out: no visual template builder, an approval review on signup, and higher cost than SES.

The reason most teams leaving SES land on Lettr: the same reliable sending, but with a clean developer API for engineers, a drag-and-drop editor for everyone else, and searchable per-email logs so you can see exactly what landed — none of it to build yourself.

Switching is mostly a settings change

Moving off SES doesn't mean rewriting anything. Point your app at Lettr over the REST API or SMTP and you're sending in minutes, with no downtime.

  1. 01 Swap your credentials — replace your SES key or SMTP login with Lettr's.
  2. 02 Verify your domain with the guided SPF, DKIM & DMARC wizard.
  3. 03 Bring your templates over — rebuild in the editor or paste your HTML.

The short version: your sending code stays the same. No more IAM policies, config sets, or SNS topics to maintain, every send and bounce shows up in one searchable dashboard, and there's no sandbox or quota ticket to deal with.
