How to configure SES/Mail Manager for controlled forwarding.

Question

Hello,

I have an S3 bucket set up to receive emails via SES using a subdomain, which is working as expected. I need to forward those emails to a verified email address on a domain we own. The challenge is that the sender will be sending approximately 6,000 emails at once, but Gmail has a limit of 3,600 messages per hour (60 per minute). I need a solution that can forward these stored emails in compliance with Gmail’s rate limits, possibly using AWS services like Lambda, SQS, Mail Manager, or another method to throttle the forwarding process. Any proven methods our there or solid suggestions? I'm no good at JSON or Python, so I'll need some TLC.

Hello,

To handle forwarding emails within Gmail’s rate limits, you can use AWS SQS and Lambda to throttle the process.

You can use S3 to store incoming emails, then throttle forwarding using an SQS queue and a Lambda function to process and send emails at a controlled rate (e.g., 60 per minute) to comply with Gmail's limits.
