Deliverability Pre-Flight Gate

The Deliverability Pre-Flight Gate is a free Claude Skill that blocks a planned outbound send before it goes out if it would push a sending domain past safe volume thresholds, based on domain-age ramp stage, SPF/DKIM/DMARC authentication, and recent bounce/complaint rates.

What this is (and isn’t)

A gate function you call before sending, not a hosted service or an ESP integration, and not a full domain-reputation ML model. It applies Google/Yahoo’s published 2024 bulk-sender guidance as a conservative rule set.

Sending-infrastructure territory, not conversation

Deliberately distinct from any conversational ai-sdr-* skill: this never writes or sends a message. It only decides, before you send, whether a planned volume is safe for the sending domain right now.

FAQ

Is this skill free to use?

Yes. Free to download and run yourself. MV3 charges $175/hr only if you want it wired into your real sending infrastructure so it gates sends automatically.

What data do I need?

Domain age, SPF/DKIM/DMARC status, and recent daily send/bounce/complaint counts for the sending domain.

Does this replace a full domain-reputation tool?

No, and the docs say so directly. This applies published Google/Yahoo bulk-sender guidance as a conservative rule set, not a full reputation ML model.

Does my sending data get sent to MV3?

No. The gate function runs entirely in your own environment.

Which sending platforms does this work with?

Any platform you can pull domain age, auth status, and send history from, including Outreach, Salesloft, Instantly, or a custom sender.
