Transactional Pro ("we," "us," or "our") operates a transactional email API service that allows developers to send application email such as receipts, password resets, OTPs, and notifications through a simple REST API powered by Amazon SES. This Privacy Policy explains how we collect, use, store, and protect your information when you use our services.
When you register for an account, we collect your name, email address, and password. If you sign in using Google OAuth, we receive your name, email address, and profile picture from Google. We also collect billing information when you purchase email credits through our payment processor, Paddle.
When you send messages through our API, we process the recipient email addresses, subject lines, message content, and any metadata you attach to each request. This data is submitted by you through the API and is processed on your behalf solely to deliver your email and provide sending logs.
We store the API keys you generate and the configuration of your verified sending domains, including the SPF, DKIM, and DMARC DNS verification records associated with each domain.
When you send email through our platform, we collect delivery events including accepted sends, deliveries, bounces, and complaints reported by Amazon SES, as well as optional open events (via tracking pixels) and click events (via link tracking). This data is tied to individual messages to provide you with logs and analytics.
We automatically collect information about how you use our platform, including pages visited, API endpoints called, browser type, IP address, and device information. We also record domain verification records when you configure verified sending domains.
We use the following third-party services to operate our platform:
Amazon Web Services (AWS SES)
Email delivery infrastructure. Recipient email addresses and message content are transmitted to AWS SES for delivery, and delivery, bounce, and complaint events are received back from SES.
Paddle
Payment processing. Paddle acts as our Merchant of Record and handles all payment data, invoicing, and tax compliance.
Google OAuth
Optional authentication. If you choose to sign in with Google, we receive basic profile information from your Google account.
We do not sell, rent, or trade your personal information or the email data you send through the API to any third party. We only share data with the service providers listed above as necessary to deliver our services.
You are the data controller for any recipient data you send through our API. You are responsible for ensuring that you have the necessary permissions and legal basis to email the recipients you specify in your API requests. You can:
We process recipient email addresses solely to deliver the transactional messages you send through the API on your behalf. Recipients who wish to access or remove their data should contact the sender (our user) directly, as the sender is the data controller for their recipient information. We maintain suppression of addresses that have hard-bounced or filed complaints to protect deliverability.
We implement industry-standard security measures to protect your data, including encrypted connections (HTTPS/TLS), hashed passwords, hashed API keys, two-factor authentication support, and secure session management. Payment data is handled entirely by Paddle and never stored on our servers. While no system is completely secure, we take reasonable precautions to protect your information from unauthorized access, alteration, or destruction.
We use essential cookies to maintain your session, remember your authentication state, and store your interface preferences (such as appearance settings and sidebar state). These cookies are necessary for the platform to function and cannot be disabled. We do not use advertising or third-party tracking cookies.
We retain different categories of data for different periods:

Your data may be processed and stored in the United States through our infrastructure provider, Amazon Web Services (AWS). For transfers of personal data from the EEA or UK, we rely on appropriate safeguards including the EU-US Data Privacy Framework and Standard Contractual Clauses (SCCs) as approved by the European Commission. Our payment processor, Paddle, may also process billing data internationally in accordance with their own privacy commitments and applicable data transfer mechanisms.
Our service is not directed to individuals under the age of 16. We do not knowingly collect personal information from children. If we become aware that a child under 16 has provided us with personal data, we will take steps to delete that information promptly.
We may update this Privacy Policy from time to time. When we make significant changes, we will notify you by email or by placing a prominent notice on our platform. Your continued use of the service after changes take effect constitutes acceptance of the updated policy.
