From the first subscriber to the hundred-thousandth campaign, Qulaq keeps your workflow fast and your senders clean.
Enterprise-grade deliverability
Built-in DKIM, SPF and DMARC alignment, suppression list sync and Gmail/Yahoo 2024 bulk-sender compliance — out of the box.
Real-time segmentation
Filter subscribers on any field in milliseconds. Automations fire on the exact moment a condition flips.
Drag-and-drop editor
A block-based composer that feels like writing in a doc. Templates render identically on every client we test.
Analytics that answer questions
Opens, clicks, revenue per campaign, cohort retention — exported to your warehouse if you need it.
Automations without the maze
Build journeys with conditions, delays and splits. Visual canvas that versions like code.
First-class API
Every feature of the dashboard is a documented REST endpoint. Webhooks for every event.
Plug in any sending backend
Qulaq is provider-agnostic. Bring your own AWS SES account, use our managed SES tenant, run your own Postal server, or just point at a plain SMTP relay — the same campaigns, segments and analytics light up.
