AWS SES Setup

1. Create IAM User

1. Go to IAM Console → Users → Create user
2. Name: plunk-ses
3. Attach a custom policy with required permissions (see below)
4. Create access keys → Save credentials

Required IAM Policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "ses:SetIdentityMailFromDomain",
        "ses:GetIdentityDkimAttributes",
        "ses:SendRawEmail",
        "ses:GetIdentityVerificationAttributes",
        "ses:VerifyDomainDkim",
        "ses:ListIdentities",
        "ses:SetIdentityFeedbackForwardingEnabled"
      ],
      "Resource": "*"
    }
  ]
}

2. Create SNS Topic

1. Go to SNS Console → Topics → Create topic
2. Type: Standard
3. Name: plunk-ses-events
4. Create topic
5. Create subscription:
   • Protocol: HTTPS
   • Endpoint: https://api.yourdomain.com/webhooks/sns
6. Plunk automatically confirms the subscription. If it fails, check your logs for the confirmation URL.

3. Create Configuration Sets

Tracking Configuration Set

1. SES Console → Configuration sets → Create set
2. Name: plunk-tracking
3. Add event destination:
   • Name: sns-events
   • Event types: Sends, Deliveries, Opens, Clicks, Bounces, Complaints
   • Destination: SNS → Select plunk-ses-events topic

No-Tracking Configuration Set

1. Create another set named plunk-no-tracking
2. Add event destination with only: Sends, Deliveries, Bounces, Complaints

4. Configure Environment

AWS_SES_REGION="us-east-1"
AWS_SES_ACCESS_KEY_ID="your-access-key"
AWS_SES_SECRET_ACCESS_KEY="your-secret-key"
SES_CONFIGURATION_SET="plunk-tracking"
SES_CONFIGURATION_SET_NO_TRACKING="plunk-no-tracking"

5. Add Your Domain in Plunk

Once you have configured AWS SES with the above settings, you can add and verify your domain directly through the Plunk dashboard. Plunk will handle the domain verification and DKIM setup with AWS SES automatically and show you the right records to add to your DNS.

6. (Optional) Configure Inbound Email

If you want to use Plunk's Receiving emails feature, configure SES inbound separately. Plunk does not auto-provision receipt rules, so this is a manual one-time setup in your AWS account.

Not all AWS regions support SES inbound — confirm inbound-smtp.<your-region>.amazonaws.com exists for your AWS_SES_REGION before continuing. If your region doesn't support inbound, you can keep outbound on your current region and run a separate identity in a region that does.

Create a receipt rule set

1. SES Console → Email receiving → Rule sets → Create rule set (or use an existing one)
2. Add a rule:
   • Recipient conditions: *@yourdomain.com (or specific addresses you want to receive)
   • Actions: Publish to Amazon SNS topic → select your plunk-ses-events topic (or create a separate topic that's also subscribed to https://api.yourdomain.com/webhooks/sns)
3. Set the rule set as active

Inbound IAM permissions

Plunk doesn't call SES inbound APIs at runtime — the IAM policy from step 1 covers everything Plunk needs. Configuring receipt rules in AWS is a manual one-time action you do as an AWS admin.

Add an MX record

For each verified domain you want to receive on, add an MX record pointing at the SES inbound endpoint for your region:

Type:  MX
Name:  yourdomain.com
Value: 10 inbound-smtp.<your-region>.amazonaws.com

Plunk's dashboard will show the exact value to use for your configured region.

7. (Optional) Move Out of the SES Sandbox

By default, new AWS SES accounts are in sandbox mode with strict limits:

• Send only to verified addresses
• 200 messages per 24 hours
• 1 message per second

Sandbox is fine for testing but useless for production. Request production access in the SES console (Account dashboard → Request production access) — AWS typically approves within 24 hours after a short questionnaire about your sending practices.

After approval, your sending quota will reflect a much higher daily and per-second limit specific to your account.

8. (Optional) Configure a MAIL FROM Domain

For better DMARC alignment, you can configure a custom MAIL FROM subdomain (e.g. mail.yourdomain.com). In the SES console under Verified identities → your domain → MAIL FROM domain, set a subdomain and add the additional MX and TXT records SES displays. Plunk's IAM policy already includes ses:SetIdentityMailFromDomain to support this.
