5 Open Source Email Marketing Platforms

Are you looking for the right email marketing tool for your company? There are many free and paid solutions on the market. In our article, you'll find a list and comparison of the most interesting open source systems that allow the user to manage the contact database, create campaigns and improve work thanks to automation.

Features of a good email software

The modern digital customer expects engaging experiences when using corporate platforms and business applications. Well-conducted email marketing activities can support your efforts to provide customers with the highest-quality experiences with your brand. Well-thought-out mailing campaigns can also help you increase your sales. Interesting email content may engage customers as effectively as activities carried out in social media. That's why choosing the right tool is so important.

Email software should first of all allow for creating and sending email messages using a WYSIWYG editor. A library of email templates will also be very useful. Thanks to it, you can use the ready-made layout of elements and simply add the created content. With the help of an email marketing platform, you can create and send many more types of content than just product offers. You can use such a tool to create invitations to events, distribute ebooks, inform about what is happening in the company or about a new publication. Templates and an editor equipped with the necessary tools (the ability to define styles, basic text formatting tools, creating columns or tables, adding graphics) will allow you to create messages that are attractive in terms of substantive content, but also visually. When creating content, anti-spam analysis may also be useful. The user receives information about the probability of their message being marked as spam, thanks to which they can still modify the content before sending it.

One of the most important functionalities allowing for creating and managing advanced email marketing campaigns is the user segmentation. It allows for more optimal use of the contacts from your mailing database. You can group them according to various criteria and create personalized campaigns for specific audiences. Tools for analyzing and reporting the progress of ongoing email campaigns are also indispensable. They provide the user with information about the course of the campaign: open rate, click through rate (CTR), unsubscribe rate and bounce rate.

Email marketing tools are often part of marketing automation platforms. It's worth thinking about such an extensive solution, especially if you represent a medium or large company. Using such a tool ensures:

  • more precise retargeting activities,
  • more effective cross-selling and up-selling,
  • higher chance of returning to an abandoned cart or payment,
  • better digital customer experience thanks to content personalization,
  • access to many tools facilitating the daily work of a marketer.

The right tools for automating marketing activities or for email marketing will save your marketers' time and your money.

Open source email marketing platforms
