# Cold Email Drip: Residential IP Reputation Scoring API

## Email 1: Delivery Rate Audit (Day 1)

**Subject:** Your cold email reputation is at risk

Hey {{first_name}},

We analyzed 200+ cold email campaigns last month. The common thread: agencies sending through residential IPs without reputation checks first.

Result? Even "clean" IPs land in spam folders because they're unlisted on RBLs or carry ISP bounce history you can't see.

Before your next 10K send, one quick score check catches that.

## Email 2: The Problem (Day 3)

**Subject:** Re: Your cold email reputation is at risk

{{first_name}},

Most cold email tools check deliverability AFTER you hit send. By then, your IP's already burned with bounce rates.

Our API scores residential IPs before routing. One lookup tells you:
- SMTP reputation (blacklist status across 100+ RBLs)
- ISP bounce history indicators
- Spam filter behavior patterns by mailbox provider

Agencies I know use it to warm IPs in 48 hours instead of 2 weeks.

## Email 3: Proof (Day 5)

**Subject:** Case: +32% open rate, 1 API lookup

{{first_name}},

One SaaS tool builder scoring IPs before distributing them to resellers dropped hard bounces by 40%. Their resellers reported 32% higher open rates in the first month.

The unlock: they stopped guessing which IPs were warm. They scored first.

Via API. Per IP. $0.05/lookup, annually.
