One burned domain kills a quarter.

The best email ever written dies in spam. GTMHack treats sender health as infrastructure: authentication verified, domains warmed on a curve, volume capped and rotated — and MIDAS throttles before reputation dips, not after.

How it works

Guarded like production.

01

Authentication, verified

SPF, DKIM and DMARC checked on every domain before a single send. Misconfigured? Sending stays locked until it is fixed — the engine will not let you burn yourself.

02

Warmup on a curve

New domains ramp on a schedule — small, human-patterned volume that grows as reputation does. No day-one blast, no week-three blacklist.

03

Caps, rotation, throttle

Per-domain daily caps, mailbox rotation, and automatic throttling the moment bounce or spam signals twitch. MIDAS caps first, tells you why second.
