DPIA — SendGrid (transactional email)

Privacy Impact Assessment · Risk: LOW · Reviewed 2026-06-05

1. Vendor scope

Twilio SendGrid is our transactional email delivery service (data-subject request acknowledgements, notifications, reports, alerts). Outbound emails flow through SendGrid's infrastructure for delivery.

2. Categories of personal information

  • Recipient email address (tenant or data subject)
  • Email content (may include a call summary: name, number, nature of request)
  • Send metadata (timestamp, delivery status)

3. Region of processing

Email routing transits SendGrid's infrastructure (email carrier). No application data is retained at rest at SendGrid beyond short-term delivery activity logs; persistent storage remains in Canada (Montréal).

4. Legal basis (Loi 25 Art. 17)

  • SendGrid (Twilio) is bound by a mature DPA offering safeguards equivalent to Loi 25
  • The email-carrier role is intrinsic to sending notifications — sending an email necessarily transits an email provider
  • Categories limited to what's strictly necessary for delivery
  • SendGrid does NOT train AI models on customer content

5. Risk assessment

Overall: LOW. Industry-standard for transactional email.

  • Unauthorized staff access: very low (SOC 2 Type II audited)
  • AI training on data: negligible (contractual prohibition)
  • US subpoena: low (transparency reports available)
  • Datacenter breach: very low (SOC 2, ISO 27001)

6. Retention at SendGrid

  • Email activity logs: short-term (delivery/diagnostics)
  • Email content: not persistently retained beyond delivery

7. Conclusion

SendGrid is an industry-standard email carrier. Its DPA provides protection equivalent to Loi 25 requirements. Risk is LOW. Transfer is justified.
