2A. Email Finder — Data Processing Agreement
This section constitutes the Data Processing Agreement (DPA) required under Article 28 of the GDPR for use of the Email Finder feature. By accepting this DPA within the product, you enter into a binding agreement with HeroBounce.
§2A.1 Roles and Responsibilities
When you use Email Finder, you act as the Data Controller and HeroBounce acts as the Data Processor under Article 28 GDPR. You are solely responsible for ensuring that your use of Email Finder is lawful, including:

Complying with applicable anti-spam and data protection laws in your jurisdiction
Honouring opt-out and erasure requests from data subjects

§2A.2 Nature of Processing by HeroBounce
HeroBounce processes first name, last name, and company domain solely to generate and verify probable professional email addresses on your documented instruction
Email patterns (e.g. firstname.lastname@domain.com) are derived from publicly observable business email syntax and constitute Business Intelligence, not Personal Data in isolation

HeroBounce does not maintain or sell a static database of personal data; results are generated on demand per your request
Sub-processors used: BrightData Ltd (SERP pattern discovery, EU Standard Contractual Clauses in place), Resend Inc (transactional email delivery)
§2A.3 Opt-Out and Data Subject Rights
Individuals may permanently block themselves from all future Email Finder generation attempts via the public opt-out page at herobounce.com/optout. Opt-outs are stored as SHA-256 hashes — plain email addresses are never retained.
For broader GDPR data subject requests (access, portability, erasure), contact support@herobounce.com. HeroBounce will forward requests that relate to Controller-level processing to you within 3 business days.

3.3 Service Limitations
You acknowledge and accept that:
Email validation results are probabilistic, not guaranteed 100% accurate
Some email providers block validation attempts, affecting accuracy
Catch-all detection may produce uncertain results for some domains
Validation speed depends on email provider response times
We may rate-limit requests to protect infrastructure and maintain service quality
Service availability is subject to our SLA terms for your plan tier
3.4 Accuracy Metrics and Performance Claims
Regarding accuracy percentages and performance metrics displayed on our website:
All accuracy percentages (e.g., "95%+", "99.5%") are performance targets and historical averages, not guarantees for any specific validation or batch of validations
Accuracy rates are measured against our internal test datasets and may vary based on the specific domains, email providers, and email patterns in your list
"Catch-all accuracy" refers to our ability to identify catch-all domains and provide confidence scores, not a guarantee that individual emails within catch-all domains are deliverable
Actual results may vary significantly based on factors outside our control, including but not limited to: email provider policies, temporary server issues, greylisting, rate limiting by receiving servers, and changes to email infrastructure
We do not guarantee any specific bounce rate, deliverability rate, or inbox placement rate for emails you send after validation
Performance metrics on marketing materials represent best-case scenarios under optimal conditions
Important: Email validation is inherently probabilistic. No email validation service can guarantee 100% accuracy due to the dynamic nature of email systems. You should always expect some margin of error and plan your email campaigns accordingly.
