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- Lead database quality varies; verification filters may miss invalid addresses or outdated contacts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
MailerLite
- Free plan caps at 250 subscribers, 2,500 monthly emails and 2 user seats
- Comfort plan is limited to 3 user seats; unlimited seats require the Power plan
- Pricing scales with subscriber count and email volume rather than a flat seat rate, and resets to the plan's subscriber ceiling each billing anniversary
- Annual billing earns only a 10% discount versus monthly, smaller than many competitors' annual discounts
