How it works
01
Click. Deploy. Done.

A single CloudFormation stack creates the Lambda function, IAM role, and WorkMail permissions in your AWS account automatically. No CLI required.

02
Point WorkMail at your Lambda.

Create one inbound email flow rule in the WorkMail console pointing to your new function. Set it to Synchronous and you're live.

03
Spam goes to Junk. Automatically.

Every inbound email is checked against sender patterns, subject keywords, display name signals, and a continuously updated central blocklist — all before delivery. No polling. No delays.

04
Your rules, your account.

Add custom blocked senders, domains, and keywords via environment variables or your dashboard. Everything runs inside your own infrastructure. We never see your email.
