Terms of Service

Service

gtmcli provides email validation, email finding, and contact enrichment services via API, CLI, and MCP server. The service verifies whether email addresses exist by connecting to mail servers via SMTP. It does not send emails.

Accounts

You must create an account to use gtmcli. You are responsible for maintaining the security of your API keys and account credentials. Do not share API keys. Revoke compromised keys immediately from the dashboard.

Acceptable use

You agree to use gtmcli only for lawful purposes. You may not:

• - Use the service to send spam or unsolicited bulk email
• - Validate or find emails for the purpose of harassment
• - Attempt to circumvent rate limits or abuse the API
• - Resell raw API access without written permission
• - Use the service in violation of CAN-SPAM, GDPR, or applicable law

Credits and billing

gtmcli uses a credit-based billing system. Email validation costs 0.25 credits per valid result. Email finding costs 1 credit per found result. Invalid, not-found, and catch-all results are free. Credits are non-refundable. Unused credits roll over up to your plan limit.

Accuracy

We aim for 99.9% accuracy on email validation. However, email verification depends on third-party mail servers that we do not control. Some servers block verification attempts, return false results, or change behavior without notice. We do not guarantee 100% accuracy and are not liable for bounced emails.

Data ownership

You own the data you submit and the results you receive. We do not claim ownership of your contact lists, validated emails, or found contacts. We cache results temporarily (up to 7 days) to improve service performance.

API and CLI

The API and CLI are provided as-is. We aim for high uptime but do not guarantee uninterrupted service. Rate limits are enforced per plan tier. Exceeding limits results in 429 responses. The CLI auto-updates when you run gtmcli upgrade.

Termination

We may suspend or terminate accounts that violate these terms. You may cancel your account at any time from the dashboard. Remaining credits are forfeited upon cancellation.

Limitation of liability

gtmcli is provided as-is without warranties of any kind. We are not liable for indirect, incidental, or consequential damages arising from use of the service. Our total liability is limited to the amount you paid in the 12 months preceding the claim.

Changes

We may update these terms. Continued use of the service after changes constitutes acceptance. Material changes will be communicated via email.
