why people still pay for EmailOctopus
People still pay for EmailOctopus because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface. If none of that applies to you, any pick above saves $108 a year.
