Sections by Substack features and specs

  • Content Organization
    Sections allow creators to organize their content more effectively, enabling subscribers to easily navigate and find specific topics or categories they are interested in.
  • Enhanced User Experience
    By dividing content into sections, readers can have a more tailored experience as they can choose which sections to follow, making their engagement with the platform more personalized.
  • Increased Engagement
    Sections can lead to increased reader engagement by providing a more structured way to consume content, which may encourage more interaction and sharing of specific sections.
  • Monetization Opportunities
    Creators can offer exclusive or premium sections to paying subscribers, providing additional monetization opportunities and incentivizing subscriptions.

Possible disadvantages of Sections by Substack

  • Complex Setup
    Setting up and managing multiple sections could be complex and time-consuming for creators, especially for those who produce a high volume of content.
  • Subscriber Overwhelm
    If not implemented carefully, having too many sections might overwhelm subscribers, leading to decision fatigue in choosing which sections to follow.
  • Fragmented Audience
    With content divided into sections, there is a risk of fragmenting the audience, which could dilute community engagement if subscribers only interact within specific sections.
  • Limited to Platform
    As this feature is specific to Substack, creators who are also distributing their content on other platforms may find it challenging to maintain consistent organization across their broader content ecosystem.

MailBluster's answer

Back in early 2015, when we reached 100,000 users on one of our startups, ThemeWagon, we needed a more affordable way to send newsletters without compromising the quality of the sending. We made an MVP and sent out a couple of million emails, and 99.8% of them got delivered. At that point, ThemeWagon was saving more than $2,150 a month on email marketing software subscription fees. After that, we didnโ€™t want to keep this to ourselves and decided to share this sweet deal with everyone else. And so we did and made MailBluster.

Which are the primary technologies used for building your product?

MailBluster uses Amazon Web Services (AWS), specifically EC2 and Lambda, to host microservices and manage the platform's infrastructure, enabling scalable and controlled resource utilization. MailBluster's core technology comprises AWS services, Terraform for infrastructure management, and multiple microservices that operate on EC2 and Lambda.
