How it works

From SMTP config to inbox placement.

Six steps that turn raw mail servers into a reliable sending fabric.

STEP 01

Add SMTP configs

Host, port, encryption, auth — multi-step wizard for every outgoing server.

7-step setup

STEP 02

Group into pools

Marketing, transactional, cold outreach — route by product, team, and region.

Pools

STEP 03

Warmup & limits

Daily caps, ramp schedules, and per-endpoint safety thresholds.

Reputation

STEP 04

Verify domains

SPF, DKIM, DMARC, and tracking CNAMEs checked in one place.
