The short version

  • Only Instantly has a free tier, so it costs nothing to try first.
  • Each has a real cost: Omnisend free plan caps at 250 contacts and 500 emails per month; 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.

Omnisend

  • Free plan caps at 250 contacts and 500 emails per month
  • Standard plan is limited to 500 contacts and 6,000 emails per month before an upgrade is required
  • SMS is billed separately starting at $0.007 per message and varies by country and volume
  • Custom pricing only begins above 150,001 contacts, requiring a sales conversation at that scale

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  • Lead database quality varies; verification filters may miss invalid addresses or outdated contacts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