SendBunny vs listmonkAssemble the stack yourself for free, or pay $199 to skip straight to sending.

listmonk's license costs nothing, but the software still needs somewhere to live: a Postgres database, an application server, a reverse proxy in front of it, and a plan for backups and upgrades. None of that is difficult for someone comfortable running containers, but it is real, ongoing work that has to happen before the first campaign goes out, and it keeps happening every time a version bump or a security patch lands.

SendBunny trades the free license for a paid one and removes that assembly step. The $199 install is a CloudFormation stack that provisions everything serverless, directly into your own AWS account, with a single Create stack click. There is no database server to size, no reverse proxy to configure, and no container host to keep patched; the tradeoff is that the software is not free, and it only runs on AWS.

listmonk's own feature set is genuinely strong for its category: campaigns, subscriber management, bounce processing and SMTP or Amazon SES sending, all in software that you can read, fork and run anywhere containers run. SendBunny narrows that scope to AWS specifically in exchange for removing the assembly and upkeep entirely.

Send costs land in the same place either way, since both can route mail through Amazon SES at Amazon's own rate. What listmonk adds is the host: a database and application server sized for the list, running continuously, plus whatever time it takes to keep that host secure and up to date. SendBunny's $199 buys out that labor permanently rather than trading it for a lower sticker price.

The case for listmonk is not really about the license fee, it is about control. Software you run yourself can be inspected line by line, hosted anywhere, and modified freely, and a team with existing container operations may already have the muscle memory to run it without treating it as a new burden. For that team, the free license is close to free in practice, because the operational cost was already sunk into how they run everything else.

For a team without that muscle memory, the free license is misleading. The real cost shows up later, as an unpatched dependency, a database that needs a migration nobody scheduled, or an upgrade that breaks something at the worst time. That is the work SendBunny's $199 is priced to remove.

• Keep running listmonk if you already operate containers comfortably, want to host outside AWS, or need to modify the sending code directly.
• Move to SendBunny if you want the ownership listmonk offers without assembling and patching the stack yourself, or you are on AWS already and would rather pay once than run infrastructure indefinitely.

Both paths end with contacts and sending history under your own control rather than a vendor's. The difference is whether you want to be the one operating the machinery that keeps it that way.

1. Export your subscribers from listmonk, including list membership and subscription status.
2. Install SendBunny with the one-click AWS link, a Create stack step that takes about ten minutes.
3. Import the CSV and verify your sending domain on Amazon SES using the DNS records the app provides.
4. Cut campaigns over to the new stack, then shut down the old host, retiring the database and application server once sends look correct.
