## Review summary

Spamdrain is praised for effectively eliminating spam emails and offering easy management across devices. Users appreciate the intuitive setup and value for money.

### Cons

- Support is reported as slow, unresponsive, or confusing, especially when troubleshooting issues or subscription problems.
- Difficulties with unsubscribing or closing accounts on the website, and the service continuing to filter emails even after app uninstallation.
