Trezor warns of phishing after Brevo email provider breach
Hardware crypto wallet maker Trezor has warned customers of a second data breach affecting its ecosystem in as many months. A cyberattack on Brevo, a marketing technology company used by Trezor for email newsletters, allowed hackers to send approximately 347,000 phishing emails to Trezor customers. The phishing emails contained a malicious link that, when clicked, downloaded an app requesting the victim's wallet backup password, which could be used to steal cryptocurrency funds irreversibly. Brevo reported that hackers accessed 138 accounts due to improperly scoped permissions. Trezor emphasized that its own products and account systems were not compromised. This incident follows a previous breach at shipping partner ShipMonk that exposed personal data of over 81,000 customers, heightening risks of targeted physical attacks. Trezor is reevaluating vendor relationships and warns that email addresses may be used for future phishing attempts.

Black Friday 2026: Retailers Need Email Infrastructure Compliance
As Black Friday 2026 approaches, retailers must ensure their email infrastructure can handle high-volume surges and comply with stricter sender protocols from Gmail, Yahoo, and Microsoft. Key compliance measures include maintaining a spam complaint rate below 0.1%, implementing one-click unsubscribe, and using SPF, DKIM, and DMARC authentication. Infrastructure readiness involves dedicated send capacity, dedicated IP addresses, load-tested send windows, real-time trigger monitoring, and fallback plans. The stakes are high: in 2025, Shopify merchants generated $14.6 billion in sales over BFCM weekend, and Adobe reported Cyber Week online sales of $44.2 billion. Email remains a crucial channel, with 77% of consumers preferring it for promotions. Sinch's Mailgun, which handled 30% more emails during Black Friday 2025 and delivered over 20 billion emails, provides a checklist to help retailers maximize revenue and avoid deliverability failures that can lead to missed sales and customer dissatisfaction.
- Gmail, Yahoo, and Microsoft have increased security protocols for bulk senders ahead of Black Friday 2026.
- Retailers must keep spam complaint rates below 0.1% to avoid email throttling or blocking; crossing 0.3% triggers blocks.
- In 2025, Shopify merchants generated $14.6 billion in sales over BFCM weekend, up 27% year-over-year.

SMS Delivery Status Polling for Waitlist Outage Alerts
The article advises that teams should only rely on an SMS API for critical outage alerts if their backend can poll delivery status and own retry, escalation, cancellation, and timing logic. Delivery reliability and timing constraints drive the design: define service-level objectives, record four reliability invariants (application-owned send IDs, bounded/idempotent retries, defined next actions per delivery state, and incident recovery that suppresses obsolete alerts), and treat providers as transport adapters. The author shortlists Twilio, Vonage, Sinch, and Infrai for evaluation, provides load-testing guidance, and includes a runnable Python example that polls SMS status, honors Retry-After, and applies backoff. The recommended architecture keeps durable incident state in the application and makes provider polling a replaceable adapter.
- Choose an SMS API for critical outage alerts only if the backend can poll delivery status and implement retry, escalation, cancellation, and timing logic.
- Four reliability invariants: application-owned identifier per send; bounded and idempotent retries; every delivery state must map to a defined next action; incident recovery must stop obsolete alerts.
- Article shortlists Twilio, Vonage, Sinch, and Infrai as candidate SMS providers to validate against the same decision record.
