Marketplace Vendor Alerts: Scalable Notification Workflows

Marketplace platforms need clear, timely communication with sellers and partners. Payout changes, dispute status, and compliance milestones are operationally critical, and missing a single notification can increase support load and trust risk. SendPromptly helps marketplace teams drive these alerts directly from domain events.

Marketplace vendor event flows

• payout.scheduled -> payout summary and expected date
• payout.failed -> action-required alert with next steps
• dispute.opened -> dispute notice and evidence deadline
• dispute.resolved -> resolution result notification
• compliance.document_expiring -> proactive renewal reminder
• account.suspended -> policy enforcement notice + internal escalation webhook

Why this pattern fits marketplace ops

• One ingestion path for vendor email notifications and internal operational webhooks.
• Template versioning helps legal and policy teams review communication updates safely.
• Delivery retries and logs reduce blind spots during provider incidents.
• Environment isolation supports realistic testing before live policy rollouts.

Vendor payload fields

• vendor_id, account_tier, market_region
• payout_id, amount, scheduled_date
• dispute_id, deadline, reason_code
• compliance_requirement, expires_at

Marketplace alert rollout checklist

1. Define event keys for each vendor lifecycle stage.
2. Build templates for both action-required and informational messages.
3. Add idempotency keys based on vendor and event identifiers.
4. Monitor failed deliveries for compliance and payout-related events first.

This setup gives marketplace operations teams predictable, auditable communication at scale without maintaining a custom notification service.
