Listmonk
Listmonk is completely free to use because it is open-source software. There are no subscription fees, hidden costs, or limits on the number of subscribers or emails you can send. The software is licensed under AGPLv3, which means anyone can download, use, and modify it without paying anything.
However, you will need to account for your own infrastructure costs. This includes paying for a server or virtual private server (VPS) to host Listmonk, which typically costs between five and twenty dollars per month depending on your needs. You will also need an SMTP service to actually send the emails. Services like Amazon SES charge around ten cents per thousand emails, while others like SendGrid offer free tiers. Overall, running Listmonk costs a fraction of traditional email marketing platforms.
