the problem

SES is great — until one tenant ruins it for everyone.

You're a SaaS platform using AWS SES to send on behalf of your customers. One tenant sends something AWS doesn't like — spam, firearms order confirmations, age-gated content. AWS quarantines your entire sending account. All 400 of your other customers stop being able to send emails. Your business is on hold pending a support ticket.

→ This is a real, recurring incident pattern for multi-tenant email providers on SES.

Everything SES won't give you.

isolation

Tenant-level fault isolation

Abuse from one tenant never touches another. Your platform keeps sending no matter what any individual customer does.

industry

High-risk categories accepted

Tobacco, vape, firearms, CBD, pharma, adult, gambling, crypto. We built ahrdmail for the industries most ESPs quietly reject.

api

Low-level API, full control

Raw API access. No drag-and-drop builders, no forced templates. You call the API, we send the email.

compatible

AWS SES wire-compatible

Replace SES by swapping the client import. Same API shape, same call signatures. Existing SES code migrates in minutes.

sending limits

Done waiting on AWS
to approve your quota?

Getting out of the SES sandbox takes days. Requesting a sending limit increase means filing a support ticket, writing an essay about your use case, and waiting — sometimes to get denied anyway. And when your volume grows, you get to do it all again.

ahrdmail has no sandbox mode and no arbitrary sending caps. You onboard, you send. When you need higher limits, you ask us directly and we turn it around fast — no support ticket queue, no policy review board, no waiting.

One import change.
Everything else stays.

ahrdmail is wire-compatible with the AWS SES SDK. Migrate without touching any business logic, sending code, or email templates.

before
// Node.js
import { SESClient, SendEmailCommand }
  from "@aws-sdk/client-ses"

const client = new SESClient({
  region: "us-east-1",
  credentials: { ... }
})

await client.send(
  new SendEmailCommand(params)
)
after — ahrdmail
after
// Node.js
import { SESClient, SendEmailCommand }
  from "@ahrdmail/client"

const client = new SESClient({
  region: "us-east-1",
  credentials: { ... }
})

await client.send(
  new SendEmailCommand(params)
)

→ SendEmailCommand, SendRawEmailCommand, and SendBulkTemplatedEmailCommand all work identically.

tenant isolation

One bad actor.
Zero blast radius.

On SES, a single tenant can take down your entire sending capacity. On ahrdmail, isolation is architectural.
