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  • Lead database quality varies; verification filters may miss invalid addresses or outdated contacts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

Whereby

  • No breakout rooms, polls, or whiteboard tools
  • Hard cap of 200 participants and performance drops with groups of 12+
  • No phone dial-in option for participants without internet
  • Occasional connectivity issues and laggy screen sharing reported
