Amazon SES Alternative
The Best Amazon SES Alternative for Every Email You Send
Compare Keplars and Amazon SES on setup, sandbox restrictions, pricing, and features. No AWS account, no production access request, no IAM. Built for developers, marketers, and product teams sending transactional and marketing email.
Why Teams Look For an Amazon SES Alternative
Amazon SES is cheap and reliable at scale, but it was built as raw AWS infrastructure, not a product. Teams and individual developers often hit friction with the sandbox approval process, the lack of native templates and analytics, and having to learn AWS just to send an email.
- No Sandbox Restrictions
Every new Amazon SES account starts in a sandbox: you can only send to verified email addresses, capped at 200 emails per 24 hours and 1 per second, until AWS manually reviews and approves a production access request. Keplars has no such gate. Connect via OAuth and send to real inboxes immediately.
- No AWS Account Required
SES requires signing up for a full AWS account, configuring IAM users and policies, and picking a region just to send an email. Keplars connects through OAuth with Gmail, Google Workspace, or Outlook, no cloud infrastructure account needed.
- Templates, Analytics, and Marketing Included
SES is raw sending infrastructure only. There is no visual template editor, no campaign scheduler, and no analytics dashboard unless you wire up CloudWatch and SNS yourself. Keplars includes all of it natively from day one.

Why Teams Choose Keplars Over Amazon SES
OAuth Email Sending
Send from Gmail, Google Workspace, or Outlook. No AWS credentials, IAM policies, or region configuration to manage.
No Sandbox Approval Wait
Start sending to real recipients immediately. No production access request, no waiting on an AWS review that can take 24 hours or more.
AI-Generated Templates
Generate polished, responsive email templates with AI. SES only accepts raw HTML through the API.
Visual and Code Email Editor
Drag-and-drop and code editing in one unified tool. There is no visual builder for SES templates.
Built-In Analytics Dashboard
Real-time opens, clicks, bounces, and delivery events out of the box. SES requires manually wiring up CloudWatch and SNS to get the same visibility.
Marketing Campaigns
Run broadcast campaigns and lifecycle flows alongside your product emails. SES has no native marketing or audience management product.
Mailbox Warmup
Automatically warm up new sending domains and mailboxes to build reputation before sending at full volume.
Simple, Predictable Pricing
One flat usage-based rate. SES layers on separate charges for dedicated IPs, data transfer, and Virtual Deliverability Manager.

Before vs After
import { SESClient, SendEmailCommand } from "@aws-sdk/client-ses";
const ses = new SESClient({ region: "us-east-1" });
await ses.send(
new SendEmailCommand({
Source: "[email protected]",
Destination: { ToAddresses: ["[email protected]"] },
Message: {
Subject: { Data: "Welcome!" },
Body: { Html: { Data: "<h1>Welcome aboard</h1>" } },
},
}),
);import { Keplars } from '@keplars/sdk';
const keplars = new Keplars({
apiKey: process.env.KEPLARS_API_KEY,
});
await keplars.emails.sendInstant({
to: ['[email protected]'],
subject: 'Welcome!',
html: '<h1>Welcome aboard</h1>',
is_html: true,
});Event notification mapping
Amazon SES publishes events through SNS topics. Keplars fires the same events as webhooks, no SNS topics or subscriptions to maintain.
Templates, contact lists, and domain settings all carry over. Full details in the migration guide.
