Pay for the mail you send.
Test the integration in a restricted sandbox, then choose a production volume. Every paid plan includes the full transactional platform.
Sandbox. Every account can send 100 test messages per month to verified recipients before subscribing. Production domains require a paid plan.
Enterprise. Dedicated infrastructure, SSO/SAML, a signed SLA and negotiated volume for products sending millions. Talk to sales →
Send anywhere
REST API, TypeScript and Python SDKs, SMTP relay, CLI and MCP tools.
Protect delivery
DKIM, SPF, DMARC, suppression handling, unsubscribe and reputation controls.
Run conversations
Inbound addresses, threads, replies, templates, webhooks and message analytics.
Why is there no free production plan?+
A small paid commitment discourages disposable abuse accounts and helps protect the shared sending infrastructure. The sandbox stays free for integration testing, but production sending requires a verified domain and an active subscription.
What happens at the monthly limit?+
We warn you as usage grows and stop new sends at the published allowance. We do not create surprise overage charges. Move to a higher volume before the limit or wait for the next UTC month.
When will marketing email be available?+
Lists, segments and campaigns come first; safe gradual sending, campaign analytics and automations follow. Marketing checkout remains closed until those controls are production-ready.
Does receiving count toward the allowance?+
The initial paid catalog meters outbound recipients. We will announce any future inbound metering before it changes; simulated inbound messages never count.
Test freely. Send for real from $3.
