Privacy Policy for SMTP
Effective Date: September 1, 2025
1) What data we access
Email account identifier (your email address).
OAuth tokens (access/refresh tokens) required to authenticate SMTP.
Operational metadata (timestamps, delivery status).
We do not read or store email content or attachments via this integration.
2) Why we access this data
We use the data only to:
Authenticate your account to send emails via SMTP from Campaign Butler.
Maintain a secure connection and ensure deliverability and abuse prevention.
We do not use the data for advertising or for building user profiles.
3) Google user data & Limited Use
For Google Accounts, we use OAuth 2.0 with the https://mail.google.com/ scope only to enable SMTP sending. We comply with the Google API Services User Data Policy, including the Limited Use requirements:
Access only what is necessary for the feature.
No human access to Google user data unless (a) we have your explicit consent, (b) it’s necessary for security or abuse, or (c) required by law.
No selling or sharing Google user data with third parties except as required to provide the service or by law.
4) Storage, retention, and deletion
Tokens are stored encrypted at rest and in transit.
We retain tokens only while your SMTP connection is active.
When you disconnect SMTP or revoke access, we delete or disable tokens promptly.
You may revoke our access anytime in your Google Account → Security → Third-party access settings.
5) Security
We use industry-standard security, including encryption, least-privilege access, auditing, and network controls to protect tokens and operational metadata.
6) Data sharing
We do not sell or rent data. Limited sharing may occur with infrastructure or email delivery sub-processors strictly to provide the service and under confidentiality and security obligations. We publish any current sub-processors upon request.
7) Your choices & access
Revoke access anytime from your email provider’s security settings.
Contact us to request deletion confirmation related to your SMTP connection.
