}'Features
Everything you need to deliver mission-critical emails without blocked SMTP ports, domain verifications, or complex DNS configurations.
Bypass Blocked Ports
Railway, Render, and most free cloud hosts block outbound SMTP ports. SendLiberty relays through your connected Google account, no SMTP port required. Emails land in the inbox, not spam.
Zero DNS Setup
No domain needed, no MX records, SPF, or DKIM to configure. Connect your Google account and start sending immediately.
Simple API
One POST request. No SDK to install. Works from any language or framework.
Inbox Delivery
Because emails are sent from your own Google account, they land in the inbox, not the spam folder.
OAuth2 Secured
We connect to your Google account via OAuth2. We never see or store your password, only an encrypted access token you can revoke at any time.
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.
Will my emails land in the inbox?
Yes, absolutely. Because the emails are sent using Google's official, highly trusted outbound mail servers, they inherit the absolute highest deliverability rates out of the box, almost bypassing spam filters and avoiding blocked ports.
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 500 emails/day per connected personal/product Gmail account, or up to 2,000 emails/day per connected Google Workspace account.
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.
