Plunk Plans Pricing
Plunk offers a simple usage-based model on its hosted cloud: a Free Forever tier that includes 1,000 emails per month (with Plunk branding, no credit card required) and a Pay-as-you-grow tier billed at a flat $0.001 per email with no base fee. Contacts are unlimited on both tiers. Because Plunk is open-source under AGPL-3.0, the entire platform can also be self-hosted with Docker Compose at no per-email cost, where the only spend is your own infrastructure and outbound email provider.
