The short version

  • Each has a real cost: Flock the Starter plan only makes the most recent 10,000 messages searchable and caps public channels at 10; Instantly shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms

Where each one falls short

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

Flock

  • The Starter plan only makes the most recent 10,000 messages searchable and caps public channels at 10
  • Starter storage is 5 GB for the entire team, against 10 GB per member on Pro and 20 GB per member on Enterprise
  • Starter allows a single team admin and a single approved domain
  • Group video calls and screen sharing require the Pro plan; Starter is limited to 1-1 video calls
  • Group video calls are capped at 20 participants even on Enterprise
  • Single Sign-On and Active Directory sync are Enterprise only
  • Enterprise is quote only, with no published rate, and is positioned for organisations with 100 or more members
  • Unlimited auto-join and announcement channels require Enterprise; Starter and Pro get one of each

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  • Lead database quality varies; verification filters may miss invalid addresses or outdated contacts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
