I'm moving our newsletter away from Mailchimp because the cost has become too high for roughly 1,200 subscribers. The planned setup is a DigitalOcean VM running Listmonk with Amazon SES handling delivery. We completed the required SES setup steps, but our request to move out of the sandbox was denied without an explanation. Listmonk is configured to automate subscriber confirmations, bounce handling, unsubscribes, and other list-management tasks. Are there additional expectations for newsletter senders, or is SES simply a poor fit for this use case?

The frustrating part is that SES approval decisions can be difficult to interpret, and denials may not include useful details. If you try again, provide a concise description of the publication, how subscribers explicitly opt in, how you process bounces and unsubscribes, your projected volumes, and the safeguards preventing unsolicited mail. If approval still fails, comparing dedicated email providers may save time rather than relying on SES for the whole newsletter workflow.
SES can be a good delivery engine, but it isn’t really a newsletter-management platform. A newsletter with a relatively small audience may not match the use case Amazon wants to approve, especially if the request doesn’t clearly document consent, list hygiene, content, sending frequency, and complaint handling. A service designed specifically for newsletters might be easier if you don’t want to keep appealing an opaque decision.
Amazon will likely want to see that list maintenance is fully automated. That includes confirmed opt-ins, reliable bounce and complaint handling, automatic unsubscribe processing, suppression of invalid addresses, and a clear explanation of how subscribers join the list. Even if Listmonk handles these features, describe the workflow explicitly in the production-access request and include your expected sending volume and frequency.
Those parts are already automated through Listmonk, similar to what Mailchimp provides. I’ll make sure the request explains each workflow in detail.

That’s why I’m hesitant to build more around it. The service may be inexpensive, but an unexplained and difficult-to-appeal decision is a serious operational risk.
