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.
SendPortal
SendPortal is completely free to download and use. There are no subscription fees, no per-subscriber charges, and no feature limitations. The software is open-source and licensed under MIT, which means you can use it for any purpose, including commercial projects.
However, you will need to cover two costs:
Hosting: You need a web server to run SendPortal. This could be a shared hosting account, VPS, or cloud server. Costs vary from $5 to $50 monthly depending on your needs and traffic.
Email Sending Service: SendPortal connects to third-party services to send emails. Amazon SES costs around $0.10 per 1,000 emails. Mailgun offers 5,000 free emails monthly, then $0.80 per 1,000. These services are much cheaper than traditional email marketing platforms.
