Monitor by ESP

Inbox-side monitoring for the email platform you already use

Pick the email service provider your team sends from. Each guide covers the flows, triggers, and silent-failure patterns specific to that platform, with concrete steps for setting up a Telltide monitor against it.

By platform

ESP-specific monitoring guides

Telltide is platform-agnostic on the inbox. The send-side is where things go wrong, and each ESP has its own failure modes.

Klaviyo

Monitor flows, segments, and abandoned-cart triggers. Catch the sends that didn't go out that Klaviyo's own dashboards miss.

Salesforce Marketing Cloud

Journey Builder activities, transactional sends, and triggered emails. Watch from the inbox, not the SFMC log.

HubSpot

Workflow emails, lifecycle journeys, and transactional triggers. Independent confirmation that what HubSpot says it sent actually arrived.
