SendPortal is an open-source email marketing application that you host on your own server. Unlike paid services that charge per subscriber or per email, SendPortal is completely free to download and use. You just pay for your own hosting and the email sending service you choose.

The platform includes all the features you need to run email campaigns: subscriber lists, custom templates, message tracking, and detailed reports. It can handle multiple workspaces, making it useful for agencies managing different clients. SendPortal connects to major email providers through APIs, which means you get professional email delivery at wholesale prices.

Because it is self-hosted, you maintain complete control over your data and can customize the platform to fit your exact needs.

What makes MailerLite special is its combination of powerful features and user-friendly design.

Pricing of SendPortal and MailerLite

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.

MailerLite

MailerLite offers flexible pricing to fit different business needs. The Free plan supports up to 500 subscribers with 12,000 monthly emails, including essential features like automation, landing pages, and 24/7 support for 14 days.

The Growing Business plan starts at $10 per month for 500 subscribers and adds unlimited templates, dynamic emails, multivariate testing, and the ability to sell digital products. The Advanced plan at $20 per month includes smart sending, Facebook integration, custom HTML editor, enhanced automation, and an AI writing assistant.

For large businesses, the Enterprise plan offers unlimited user seats, dedicated support, a success manager, and priority deliverability consultation. MailerLite also provides Transactional Email plans starting at $7 per month, with separate pricing for high-volume email sending via API.
