Revenue model

Email Marketing Platform Subscriptions: Tiered subscription plans (Free, Starter, Essential, Premium, Custom Enterprise) priced based on monthly email volume. Annual payment offers 10% discount. Free tier provides 6,000 emails/month with daily limit of 200. Paid plans range from $9/month (8,000 emails) to $27/month (15,000 emails) with custom enterprise pricing for high-volume senders.
Volume-based Email Pricing: Pricing based on number of emails sent per month rather than contact list size. Volume-based plans (50,000; 100,000; 250,000; 500,000+ emails) help avoid contact-based fees and keep costs predictable as audience grows. Unlimited contacts included on Essential and Premium plans.
Freemium Entry Tier: Free plan with unlimited contacts and monthly send limit for initial adoption. No credit card required at signup. Users can upgrade to access more features and increase sending volume.
Overage Billing: If users exceed their email credit allowance, additional emails are billed per 1,000 emails beyond plan limit.
