DoubleZero
DoubleZero offers two pricing options that stand out from typical subscription services.
The Free Version is completely open source and available at no cost. You can download the code, host it yourself, and use all core features including transactional emails, monitoring dashboard, multi-recipient tracking, SMTP endpoint, and REST API access. Your only costs are AWS SES fees, which are extremely low at around $0.10 per thousand emails.
The Pro Version costs $175 as a one-time purchase. This is not a monthly subscription. You buy it once and own it forever. Pro adds powerful features including a WYSIWYG email editor, contact management system, email lists, broadcast campaigns, team collaboration tools, activity feed, and automation workflows.
Both versions require you to provide your own AWS account and hosting, giving you complete control and keeping ongoing costs minimal.
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.
