WordPress vs Substack: Newsletter Platform vs Full CMS

Substack has transformed newsletter publishing, making it easy for writers to launch paid subscriptions and grow audiences quickly. WordPress is a full CMS that can also power newsletters through plugins like MailPoet or integrations with Mailchimp and ConvertKit. Each serves a different creator journey.

The 10% Problem

Substack takes 10% of all paid subscription revenue plus Stripe's 2.9%+30¢ per transaction. At $10,000/month in subscription revenue, you pay $1,290 to Substack and Stripe before any other costs. With WordPress, you keep nearly all revenue — $9/mo hosting plus your payment processor's standard rate.

Long-term SEO Value

Posts on Substack live on a Substack subdomain. You build Substack's domain authority, not your own. WordPress posts on your domain compound over time into a durable SEO asset that you own outright.

Verdict

Substack is the fastest way to launch a paid newsletter with zero setup. WordPress is better for creators who want full ownership, multi-channel monetization, and SEO-driven growth. SiteICO makes WordPress setup instant and includes AI content tools to help you publish more consistently.
