What is SendPortal

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.

FAQ's About SendPortal

Is SendPortal really free?
Yes, SendPortal is 100% free open-source software. You can download and use it without any charges. However, you need to pay for your own web hosting and an email sending service like Amazon SES or Mailgun to actually send emails.
Do I need technical skills to use SendPortal?
Basic technical knowledge helps with installation. You need to set up a web server, install the application, and configure email service credentials. Once installed, the interface is user-friendly. If you are not technical, consider hiring a developer for initial setup.
How is SendPortal different from Mailchimp?
SendPortal is self-hosted and free, while Mailchimp is a paid cloud service. With SendPortal, you own your data and pay only for hosting and email delivery. You get unlimited subscribers at no extra cost. Mailchimp charges based on subscriber count.
Can agencies use SendPortal for multiple clients?

What email services work with SendPortal?
