The short version

Each has a real cost: Instantly shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms; Listmonk it is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Instantly

Shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms
AI campaign generation, whilst useful, produces generic copy; personalisation still requires manual review and editing for high-quality outreach
Email as primary channel faces declining effectiveness; spam filtering improves and email open rates decline generally
Lead database quality varies; verification filters may miss invalid addresses or outdated contacts
Freemium model limits features significantly; advanced analytics, API access, and priority support require paid tiers

Listmonk

It is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.
Running it means running PostgreSQL, backups, upgrades and a mail relay, and the true cost is the engineering time to keep that stack healthy rather than the zero licence fee.
The campaign editor and analytics are basic next to Mailchimp or Klaviyo: reporting is limited to opens, clicks and bounces, with no revenue attribution, no ecommerce integration and no deep engagement scoring.
SQL-based segmentation puts audience definition beyond a non-technical marketer, so a marketing team without engineering support will be blocked on routine tasks.
The AGPLv3 licence obliges you to release source modifications if you offer the software as a network service, which is a real constraint for anyone considering embedding it in a commercial product.
