why people still pay for Copper
People still pay for Copper because CRM value compounds as the system becomes the shared memory of every customer interaction and embeds itself in the rest of the stack. The recurring cost buys deduplication, permissions, imports, sync, enrichment, email capture, automations, backups, and audit history, not just the visible interface. If none of that applies to you, any pick above saves $348 a year.
