Email API & Marketing Platform built for developers, marketers & AI agents

An email platform that handles everything in one place: transactional API, marketing campaigns, automations, contact management, and AI integration. You get SDKs for 10 languages, SMTP relay, real-time webhooks, and an MCP server so AI agents can manage your email infrastructure too.

Anyone who sends email. Developers use the API and SDKs for transactional stuff like password resets and receipts. Marketers run campaigns and drip sequences. AI agents connect through the MCP server to send, track, and manage everything by conversation.

You get 3,000 transactional emails per month and 1 sending domain. No credit card, no trial that expires. Use it as long as you want. When you need more volume or marketing features, upgrade anytime.

Official SDKs for Node.js, Python, PHP, Ruby, Go, Java, .NET, Rust, Elixir, and Laravel. If your language is not on the list, use the SMTP relay. It works with anything.

SendGrid and Mailgun split transactional and marketing into separate products with separate pricing. Resend is API-only with no campaigns, automations, or contact management. Sendkit includes transactional API, campaigns, automations, contact management, and an MCP server for AI agents. One account, one bill.

A Model Context Protocol server with 60+ tools. Connect it to Claude, Cursor, VS Code, or any MCP client and your AI agent can send emails, manage domains, create campaigns, build automations, and pull delivery metrics. All through natural language. If you can do it in the dashboard, your AI can do it too.

We take care of it so you do not have to. IP reputation management, automatic DKIM/SPF/DMARC setup, blacklist monitoring, disposable email filtering, and automatic suppression lists for bounces and complaints. High-volume senders get dedicated IPs. You see everything in real time: opens, clicks, bounces, complaints.

Absolutely. REST API or SMTP, your choice. If you already use Nodemailer, PHPMailer, ActionMailer, or any other mail library, just swap the credentials and you are sending through Sendkit. Full tracking and analytics either way.

That is the whole point. Transactional emails like order confirmations go through the API. Marketing emails like newsletters go through the campaign editor. Same account, same contacts, but separate reputation tracking so one does not affect the other.

No contracts, no cancellation fees, no tricks. Month-to-month billing. Upgrade, downgrade, or cancel whenever you want.

Real-time webhooks for every event: delivered, opened, clicked, bounced, complained, unsubscribed. Use them to update your database, trigger workflows, or feed your analytics. No polling, no delays.

A visual builder lets you create drip sequences, onboarding flows, re-engagement campaigns, and event-triggered emails. Set conditions on contact properties, engagement history, and time delays. It runs on its own once you set it up.

Before you send anything, Sendkit checks syntax, verifies the domain has mail servers, flags disposable addresses, and catches role-based emails like info@ or admin@. Fewer bounces, cleaner lists, better reputation.

Fully compliant with GDPR, CAN-SPAM, LGPD, and CASL. Built-in unsubscribe handling, suppression lists, consent tracking, and encryption for data at rest and in transit. You do not need to build any of that yourself.

99.9% uptime on globally distributed infrastructure. Emails process in milliseconds with automatic retries and failover. Every email gets a delivery log you can inspect in the dashboard or pull through the API.

Sign up, add a domain, verify your DNS records, and send your first email. The whole thing takes about 5 minutes. No credit card required.
