Built for teams that want control without provider lock-in.

Unified API

Integrate once. Route anywhere.

Send through one clean SDK while Carbon handles provider-specific formatting, retries, and routing behind the scenes.

Provider flexibility

Switch providers without code changes.

Move from SMTP2GO to SES or add Mailgun for backup delivery without touching your application integration.

Developer visibility

Readable logs and event timelines.

Track queued, sent, delivered, bounced, and failed messages from a normalized dashboard built for fast debugging.

Webhooks and templates

Build repeatable transactional flows.

Keep template management, webhook replay, and provider events inside one operational layer for your team.

Carbon sits between your app and every provider connection.

Your application talks to one API. Carbon chooses the provider, records the event timeline, and keeps your delivery workflow portable.

Questions teams ask before switching their email workflow.

Carbon is designed to reduce migration risk, not increase it.

No. Carbon is built around bring-your-own-provider workflows, so you can connect the provider you already use and keep ownership of that account.

Launch faster

Use your own provider. Keep one integration surface.

Start with SMTP2GO, add SES later, and keep your product code clean while Carbon handles the operational layer.
