What Intello monitors across Marketing & Email
Every layer of the marketing & email messaging API surface is watched in real time, from spec revisions to policy footnotes.
Spec changes
Diff send and delivery endpoints for added, removed, or retyped fields.
Webhook events
Track delivery receipt shape, new statuses, and retry semantics.
Compliance & content rules
Watch for updated opt-out, A2P, and content-validation requirements.
Rate limits & throughput
Surface new per-sender and per-account throughput caps.
Why Marketing & Email monitoring matters
Messaging APIs touch customers directly. Changes to send endpoints, delivery webhooks, or rate limits surface as bounced notifications, missed alerts, and angry support tickets. Intello tracks every published change across marketing & email messaging APIs so you find out from us — not from a customer ticket.
- Send endpoint changes
- Delivery webhook drift
- Template and content rules
Common marketing & email change types & risks
These are the change patterns most likely to break marketing & email integrations in production.
Send endpoint changes
Renamed parameters, new required fields, or stricter validation that rejects previously-valid payloads.
Delivery webhook drift
New event types, renamed statuses, or changed retry policies that break delivery tracking.
Template and content rules
Updated compliance, opt-out, or content-length requirements that cause silent send failures.
Number and sender identity
Changes to A2P registration, sender verification, or number pool management.
Rate limit and throughput caps
New per-number or per-account throughput ceilings that throttle campaigns.
Media and attachment formats
Updated MIME type support or size caps that reject previously-working attachments.
