our call
Start with MailMunch — highest vibe code, weakest moat.
MailMunch
MailMunch is essentially a collection of overlay triggers (exit-intent, timers) connected to a basic contact store and email dispatcher. Paying monthly for modal triggers when modern UI components and transactional email APIs exist is unnecessary. Rebuilding the popup logic takes hours; mailing lists can be sent to Listmonk or directly to Resend/Klaviyo.

- Exit-intent, scroll-depth, and delay-based popup triggers
- Subscriber contact storage and double opt-in verification
- Simple automated welcome email sequences

OptiMonk
OptiMonk's core utility—triggering targeted popups and capturing leads—is straightforward JavaScript DOM manipulation combined with a backend API.
