SaaS / business softwareNews, forums & reviewsOriginal by Substack
Substack lets writers connect with readers directly over email, with no algorithm in between. A newsletter works as a website, an email list and a payment page all at once; the writer owns the subscriber list and can put content behind a paywall if they wish. That simplicity and sense of independence is the main reason journalists and experts choose the platform.
Building something similar takes an author dashboard, an automatically generated newsletter site for each publication and a high-volume email delivery infrastructure. Subscription and payment management, free versus paid content separation, open and click statistics, comments and podcast support run in the back end. To protect sender reputation, SPF, DKIM and DMARC setup and unsubscribe rules must be flawless.
How Substack works: the core user flow
How many apps and dashboards do you need?
Author dashboard
The web panel where the writer drafts posts, schedules sends and tracks subscribers and revenue.
Newsletter site
The public site that hosts each publication's archive, subscribe form and payment page.
Reader app
The mobile app where readers follow all their newsletters in one place and leave comments.
Admin panel
The internal panel that monitors sending queues, payments, abuse reports and email reputation.
Critical features of a product like Substack
Bulk email engine
Posts are sent to thousands of subscribers through a queue, and bounced or complained addresses are removed automatically.
Paid subscription tiers
Monthly, annual and founding-member plans are defined, and all or part of a post is opened to paying subscribers.
Subscriber import and export
Writers can upload an existing email list and export all their subscribers at any time if they decide to leave the platform.
Recommendation network
Writers recommend each other's newsletters, and new subscribers are shown similar publications to drive cross-growth.
Send statistics
Opens, clicks, new subscribers and paid conversion rates are reported for each post.
Podcast and audio posts
Writers attach audio to publish their newsletter as a podcast too, with a private RSS feed generated for paying subscribers.

The hard parts
Email deliverability
A single spammy publisher can drag down the sending reputation of the whole platform, so IP pools and sender vetting are needed.
Payments and tax
Collecting money on behalf of writers can trigger licensing and tax obligations, so use a licensed payment institution infrastructure.
Consent and GDPR compliance
You must carefully manage proof that imported lists opted in, along with marketing email rules and GDPR obligations.
Business model
The best-fit model is free newsletter setup plus a fixed-rate commission on the writer's paid subscription income; the platform only earns when the writer earns. A professional plan with custom domains, advanced analytics and team features, a plan for corporate publishers and in-newsletter sponsorship matching can add further revenue lines.

Choosing a company to build an app like Substack
Most people searching “build software like substack” are really looking for a reliable app development company. When comparing quotes, check four things:
- Can you try similar products they have shipped, in the stores or live?
- Are the source code, design files, servers and store accounts transferred to you by contract?
- Do they show a working demo every two weeks, with written scope and acceptance criteria?
- Are maintenance, scaling and GDPR/security costs written into the quote?
Copyright and trademarks
A business model and features are generally not protected on their own, but the Substack name, logo, interface design, content and source code are. That is why we build a product with similar functionality but your own brand, design and code. This is not legal advice; we recommend a trademark search before launch.
Frequently asked questions
How long does it take to build software like Substack?
A first version with the author dashboard, newsletter site, email sending and paid subscriptions can go live in a few months. The reader app and recommendation network are added later.
Do I need a licence to collect money on behalf of writers?
Collecting and distributing payments for others can require a payment institution licence in many markets. That is why marketplace solutions from licensed providers such as Stripe Connect are recommended.
Will there be copyright or trademark issues?
The newsletter platform model and its features are generally free to use, but the name, logo, design, content and code cannot be copied. This is general information, not legal advice.
What should I look for when choosing a company to build software like Substack?
Pick a team with experience in high-volume email sending, subscription billing and payment provider integration, one that can measure deliverability.
