Choose OptinMonster if:
Marketers building an email list from existing site traffic.
ConvertKit: pros & cons
- Simple Automations: The most intuitive visual funnel builder in the market.
- Creator Network: Benefit from an internal network of other creators who can recommend you.
- High Deliverability: Known for making sure your emails actually land in the inbox.
- Commerce Ready: Sell digital products and subscriptions directly within your emails.
- Basic Editor: Its email designer is very minimalist and not meant for highly visual layouts.
- Pricing: Can be expensive compared to MailerLite or Beehiiv as your list grows.
- Reporting: Analytical dashboards are less detailed than some enterprise competitors.
OptinMonster: pros & cons
- Exit-intent and behavioural targeting
- Many form types in one tool
- Works on any platform
- Billed annually, so the monthly figure is misleading
- Aggressive popups harm user experience if overused
- Higher tiers needed for the best targeting
Our verdict on ConvertKit
The best email platform for those looking for powerful automation without the corporate headache.
Our verdict on OptinMonster
Effective at capture. Restraint is the difference between a working list and an annoyed audience.
