Compare	The Newsletter Plugin	MailPoet
Verdict	Depends	Worth it
Best for	WordPress sites wanting free newsletters	WordPress site owners
Who it's not for	Non-WordPress sites	Non-WordPress sites . the plugin is useless there

Public sentiment	Redditors actively debate whether it's worth it for lists from thousands to tens of thousands of subscribers, with free-tier appeal weighed against self-hosted tradeoffs.^⁹	Users praise the WordPress-native simplicity and price, but support and deliverability draw frequent complaints.
Biggest gotcha	Multiple 2025-2026 CVEs (XSS, CSRF, auth bypass); unpatched installs are targets	Support quality is the dominant Trustpilot complaint¹²
