| Support quality | No public support evidence found | Automated replies; hard to reach humans |
| Public sentiment | Public user feedback is sparse; one customer story reports doubled conversions and 10x traffic after migrating from Substack to WordPress.⁶ | Reviewers praise the ease of use and monetization, but many complain about automated support, platform fees, and Substack turning into another social network.13 |
| Biggest gotcha | Pricing changed multiple times: $149-$249/yr licenses, then $120/mo annual. Confirm current terms before buying.² | Support is auto-replies; no clear human escalation channel per user reports.14 |
