Public price
$0 (free open-source)
Run on your own infrastructure; no Plunk cloud fees, but you pay for your own hosting and email delivery provider.
Cost scenarios
Pricing pages show the entry point. These scenarios show what the plan means in real buying situations.
Small SaaS sending under 1,000 emails/month
Plunk: Free, with Plunk branding.. Sequenzy: More useful once lifecycle work becomes the main problem.. Plunk is hard to beat for a tiny app.
50,000 monthly emails
Plunk: About $50 at $0.001/email.. Sequenzy: Better if content strategy, lifecycle campaigns, and SaaS segmentation matter.. Plunk is transparent; Sequenzy is more guided.
Team wanting source-code control
Plunk: Self-hosting can reduce vendor dependency.. Sequenzy: Managed product workflow instead of self-operated infrastructure.. Pick based on operational appetite.
What to watch for
The free plan includes Plunk branding.
Per-email pricing is simple, but very high send volume still needs modeling.
Self-hosting reduces vendor email costs but adds infrastructure and maintenance work.
Plunk pricing is deliberately simple
Plunk avoids contact tiers, feature tiers, and add-on pricing. That makes the cost model easy to explain to engineering teams: send count is the main paid variable.
That simplicity is valuable when email is part of the product and engineers want a predictable bill. The question is whether the team also needs campaign strategy, lifecycle segmentation, and non-technical workflow ownership. Plunk can handle transactional and campaign sending, but the team still needs to decide what lifecycle content should exist and how it should evolve.
Use Plunk alternatives to compare developer-friendly email tools. Use Sequenzy vs Plunk when the decision is simple send-based infrastructure versus guided SaaS lifecycle marketing.
