Auditable Healthtech Welcome Email: Templates, API, Domain
The article advises healthtech teams to evaluate transactional email APIs (SendGrid, Resend, Postmark, Infrai) by verifying auditable evidence rather than feature lists. It defines five required artifacts for a verification-email workflow: API-accepted send, rendered body from an approved template revision, verified sending domain with DKIM rotation, correct suppression handling, and a retrievable delivery record that can be stored in the team's evidence store. The author demonstrates a pull-based reconciliation approach (example Python client calling Infrai's GET /v1/email/event/list) and recommends running synthetic-signup experiments that reuse a correlation ID and avoid production patient data. Infrai is presented as a practical API-first option that consolidates keys and billing but is pull-only for events and lacks SMTP relay or managed OTP; teams should choose providers based on observed evidence retention and operating-model fit.
- Author recommends evaluating transactional email APIs by requiring five artifacts: API-accepted send, approved-template-rendered body, verified sending domain with DKIM rotation, suppression handling, and retrievable delivery record.
- Infrai exposes email events via a pull endpoint GET /v1/email/event/list and the article includes a Python example client for pull-based reconciliation.
- Infrai is described as an API-first provider that consolidates backend access under one key/bill but does not offer an SMTP relay or pushed webhooks (events are pull-only).

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.

Shoppers Cautious About AI Holiday Shopping, Sinch Study Finds
A new study by Sinch across eight markets with 2,501 consumers reveals that fewer shoppers believe AI will make holiday shopping easier, dropping from 48% in 2025 to 43% in 2026. Trust in human advice over AI increased to 53%. Data privacy remains the top concern (43%). Consumers are most willing to delegate order tracking and shipping updates (48%), product research (47%), and customer service (36%). Despite consumer caution, 63% of retailers have deployed AI customer communication agents. The findings suggest that AI gimmicks risk alienating shoppers, while high-quality authentic content remains crucial for affiliates.
- Sinch surveyed 2,501 consumers across eight markets.
- 43% of shoppers believe AI will make holiday shopping easier, down from 48% in 2025.
- 53% trust advice from a real person more than AI, up from 51% in 2025.

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.
