About

It provides a REST API, SDKs for Node.js and Python, custom domains with DKIM, inbound email handling, analytics, and audience segmentation.

The hosted plan includes 1,000 emails per month on the free plan, unlimited contacts, and Plunk branding on emails. Paid usage is billed at $0.001 per email with no base fee and no contact limits. The product is aimed at developers and SaaS teams that need one system for receipts, password resets, newsletters, and automated email sequences.

Free Tier Value
This free tier is genuinely usable rather than a throwaway demo: it includes the core sending, automation, campaigns, tracking, custom domains, and unlimited contacts, but it is capped at 1,000 emails per month and keeps Plunk branding. At the paid rate of $0.001 per email, that allowance is worth about $1/month, and no credit card is required to start.
