Supported Notification Channels

Pulsely routes incidents through four primary delivery paths. Each channel supports rich formatting, priority tagging, and automatic retry logic for failed deliveries.

Messaging

Telegram Bot

Connect via BotFather token or webhook URL. Supports inline reply buttons for acknowledge/resolve, MarkdownV2 formatting, and channel/topic routing. Average delivery latency: 180ms.

Workspace

Slack Webhooks & App

Post to dedicated alert channels or direct messages. Includes interactive blocks for status updates, fallback to email on webhook timeout, and automatic thread management for recurring incidents.

Traditional

Email & SMS

SMTP and SendGrid integration for structured HTML/plain-text alerts. SMS fallback via Twilio for critical severities. Includes DKIM verification and bounce handling with automatic recipient rotation.

Custom Alert Templates

Replace generic pings with actionable, context-rich messages. Pulsely uses Handlebars-style templating to inject runtime metrics, endpoint details, and runbook links directly into notifications.

Smart Escalation Policies

Don’t let silent incidents drain your SLOs. Pulsely automatically routes unacknowledged alerts through predefined escalation ladders, adjusting frequency and channel based on severity and response time.

Rule

Initial Notification

Sent immediately to primary on-call via Telegram. Includes incident ID, affected service, and direct acknowledge link. Retries every 30 seconds for 3 attempts if delivery fails.

Rule

Tier 2 Escalation

Triggers after 5 minutes of no acknowledgment. Routes to Slack #incidents channel and emails the engineering manager. Message frequency increases to every 2 minutes until resolved.

Rule

Executive Alert

Activates after 15 minutes for P1 outages. Sends SMS to VP of Engineering and posts to #exec-updates. Includes MTTR projection, customer impact estimate, and automatic status page sync.
