How does the free tier work?

The free tier includes 3,000 transactional emails per month with 1 sending domain. No credit card required. When you need more volume, upgrade to a paid plan at any time.

What is the difference between transactional and marketing plans?

Transactional plans are for automated, event-triggered emails like password resets, order confirmations, and receipts. Marketing plans include everything in transactional plus campaigns, newsletters, automations, and contact management.

How does billing work?

Plans are billed monthly based on your email volume tier. If you exceed your plan limit, overage is charged at $1 per 1,000 emails. You can upgrade or downgrade your plan at any time.

Can I cancel at any time?

Yes. There are no contracts or cancellation fees. You can cancel your subscription at any time and continue using the service until the end of your billing period.

How do you handle deliverability?

We manage IP reputation, enforce DKIM/SPF/DMARC authentication, monitor blacklists, and provide dedicated IPs for high-volume senders. Our infrastructure is optimized for inbox placement.

Do you offer an SMTP relay?

Yes. You can send emails via our REST API or standard SMTP relay. Just update your SMTP credentials and start sending. Both methods support full tracking and analytics.

What about data security?

All data is encrypted in transit (TLS) and at rest (AES-256). We follow industry best practices for security and are compliant with GDPR and LGPD data protection regulations.

Do you provide SDKs and documentation?

Yes. We provide official SDKs for 10 languages (Laravel, Node.js, Python, PHP, Ruby, Go, .NET, Java, Elixir, and Rust) and comprehensive API documentation with code examples for every endpoint.

What is the MCP server?

Sendkit has a Model Context Protocol server with 39 tools. Connect it to Claude, Cursor, or any MCP-compatible client and your AI agent can send emails, create campaigns, build automations, manage contacts, and pull metrics. Everything you can do in the dashboard, your AI can do too.

Can I migrate from another email provider?

Yes. Import your contacts, templates, and suppression lists. Our SMTP relay makes it easy to switch providers, just update your credentials.

Pricing

Unlimited contacts on every plan. Pricing scales with your email volume, not your list size.
