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.
