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.

Getting started with SendPortal requires some technical knowledge, but the process is straightforward:

• Install the Software: Download SendPortal from GitHub and install it on your web server. You need a server running PHP and a database. Follow the official installation guide on their website.

• Connect an Email Service: Link SendPortal to an email provider like Amazon SES or Mailgun. You will need to enter your API credentials from the email service you choose.

• Import Your Subscribers: Upload your contact list using CSV files or add subscribers through the API. You can organize contacts into different segments for targeted campaigns.

• Create Templates: Design your email templates using HTML or use the basic editor provided. Save templates for reuse across multiple campaigns.
