## Timeline of updates

- **identified** 2026-10-26 05:31 UTC: Clients making requests to POST /v3/contacts/doubleOptinConfirmation may encounter the following error: Your SMTP account needs to be activated to use this endpoint. Please contact us at contact@sendinblue.com "contact@sendinblue.com": mailto:contact@sendinblue.com to request activation. To use the doubleOptinConfirmation endpoint, the API key must have the "Transactional Email" scope, as sending the double opt-in confirmation email is part of the flow. Only the doubleOptinConfirmation endpoint is impacted. We’re also working on improving the error message to make it more descriptive and actionable. Additionally, we’ll review the overall flow to identify opportunities to make it clearer and more intuitive for clients.
