sendkit.devAbout Sendkit
Sendkit is an email platform that sells to developers, marketers and AI agents in the same sentence, and the architecture follows from that: one API and one account covering transactional sending, marketing campaigns, drip automations and contact management, instead of the usual arrangement where a team stitches a transactional provider to a marketing provider with a handful of automations in between. Integration is deliberately shallow — SDKs for Laravel, Node.js, Python, PHP, Ruby, Go, .NET, Java, Elixir and Rust, plus a standard SMTP relay for anything not on that list, and in a framework like Laravel it is a mailer driver swap and an API key rather than a rewrite of the sending code. Delivery observability is first-class: real-time webhooks for delivery, bounce, open, click and complaint events, with open and click tracking on every tier including free. The pricing model is the sharpest differentiator in a category that almost universally bills on list size. Sendkit bills on email volume and gives every plan unlimited contacts, which inverts the economics for anyone with a large but lightly-mailed list — a common shape for a product with many free users. A volume slider on the pricing page prices the exact monthly send before signup, and dedicated IPs are available on paid tiers.
