Without Needing a Domain.
Deploying to Render or hosts where outbound SMTP ports are blocked? Sendliberty turns your product's existing Gmail into a reliable email API. Send up to 500 emails a day with zero DNS friction.
curl -X POST https://sendliberty.com/api/send \
-H "Authorization: Bearer YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"from": "Your Brand <sender@gmail.com>",
"to": "user@example.com",
"subject": "Hello via Webhook!",
"html": "<p>No SMTP needed.</p>"
}'Stop worrying about domains. Just send.
Traditional email APIs force you to configure DNS records and custom domains before sending a single email. Sendliberty uses the Gmail account your product already has.

Frequently Asked Questions
Got questions about how Sendliberty is different from other transactional email sending platforms? We have answers.
Do I need to verify my domain or configure DNS records?
No! Because Sendliberty routes your email relay requests securely through your already verified, connected Google accounts, there is absolutely zero DNS configuration required. You do not need to add SPF, DKIM, MX, or TXT records to start sending immediately.
Can I send from my custom domain (e.g. hello@mycompany.com)?
Yes! If your custom company domain is connected to Google Workspace, simply link that account to Sendliberty via Google OAuth. Sendliberty will send transactional emails directly from your custom domain (e.g. hello@mycompany.com) with zero extra DNS or SPF configuration required on Sendliberty. Plus, Google Workspace accounts get up to 1,000 emails/day on Free (2,000/day on Pro) per account!
Will my emails land in the inbox?
Sendliberty submits messages through Google's official Gmail API, but no email service can guarantee inbox placement. Gmail and the recipient's provider still classify each accepted message using sender reputation, content, authentication, recipient engagement, and other signals.
How does this compare to the free tier of Resend, Mailgun, or SendGrid?
Other platforms limit you to only 100 free emails per day on their free plans and require strict domain verification. With Sendliberty, you can send up to 200 emails/day per connected personal Gmail account (500/day on Pro), or up to 1,000 emails/day per connected Google Workspace account (2,000/day on Pro).
Can I send attachments and CC/BCC recipients?
Yes, our REST API supports complete transactional payloads. You can specify a custom Reply-To header, carbon copies (CC), blind carbon copies (BCC), and pass an array of base64-encoded attachments.
Is my Google account password secure?
We never see, ask for, or store your Google password. Authorization is done entirely through standard, secure Google OAuth2 credentials. We only store encrypted access and refresh tokens, which you can manually revoke from your Google Account settings page at any time.
