From Gmail to API in three steps.

Connect Gmail

Authorize a personal Gmail or Google Workspace account with secure OAuth.

Create an API key

Generate a scoped key and restrict it to the environments that need access.

Send your request

Call one endpoint and inspect the result in your delivery log.

Built for the email your product must send.

Questions, answered plainly.

Still unsure? Read the docs or email us and we will help you decide whether Sendliberty fits your product.

No. Sendliberty sends through a Gmail or Google Workspace account you connect with Google OAuth, so there is no separate Sendliberty DNS setup.

Yes. If your custom-domain address is hosted on Google Workspace, connect that account and send from it through the same API.

Never. Google handles authorization directly. Sendliberty stores encrypted OAuth tokens and only requests the Gmail permission required to send messages.

Yes. The API supports reply-to addresses, CC and BCC recipients, HTML and plain-text bodies, and base64-encoded attachments.

You receive a structured API error, and the debugger and delivery logs give you the context needed to resolve the request quickly.

Ready when you are

Your first transactional email is one request away.

Connect Gmail, create a scoped key, and send your first request in minutes.
