Integrate seamlessly with Open Source Email Marketing Tools

Email Marketing was, and still the most powerful and cost-effective medium to reach out to your customers. There are many commercial and a few free, open-source email marketing tools available in the market.

While it always looks lucrative to use a free service, that comes with additional responsibilities too.

One good thing is, there are not many open source email marketing software available in the market. So, this reduces your research time to evaluate the best.

Recommending an Open Source Email Marketing service comes with certain responsibilities. On one-hand we support integrations with certain open source email automation platforms for your email marketing needs. It is important for you as a user to know what metrics are we doing the same.

So essentially there are three important metrics: 

1. Responsive community

The success of any open-source software depends on how responsive its community users are, how actively they are contributing to enhancing the software, when was the last release happened and so on.

2. Speed of Sending Emails

If the size of the email list is just a few thousand, then this factor might not troubles you. But, on the other hand, if you’re a power user with list size in multiples of thousands/ a few million, then definitely this point can impact the performance of your email campaigns.

There are open-source software which can’t deliver more than 10–20k emails/hour, so if you’re an enterprise-grade email sender with requirements of sending millions of emails every hour, then the default version of these open-source software might not work. In such cases, you should look for community support, because there might be already solutions or optimisations available for your problem.

3. Support for Basic Email Marketing Features

Depending on your business requirements, you should first evaluate what exactly you’re looking for in your new email marketing tool.

You don’t have to necessarily choose a complex tool with hundreds of feature, instead focus on your requirements and how the tool can help in enhancing those. There are a few basic email marketing features, which every email marketer look for; this consists of features like-

    1. Uploading and managing bulk email lists
    2. Ease of creating responsive email templates with the help of a Drag n Drop Editor
    3. Scheduling email campaigns 
    4. Tracking the email performance like the delivery rate, the number of emails opens, clicks, bounces, unsubscribes and spam.
    5. Creating autoresponders and rule-based followup automation.

Based on some of these fundamentals, below is the list of recommendations for Free Best Open Source Email Marketing Software:
