Newsletter Growth & Sponsor OS — Ready-to-Use Excel Toolkit

The morning after a newsletter send, the issue is in one spreadsheet, a sponsor booking is buried in email, and the next placement is on a calendar. It takes extra digging to compare issue revenue, opens, unsold slots and the work spent growing the list.

Newsletter Growth & Sponsor OS brings those records into one Excel workbook so newsletter operators can review the operation in one place.

WHAT YOU CAN TRACK

• Issue calendar and send status

• Sponsor inventory, deals, discounts, net rates and CPM

• Issue revenue and revenue per 1,000 opens

• Subscriber cohorts and 30-, 90- and 180-day retention checkpoints

• Growth actions, costs and cost per subscriber

• Referral exchanges and planned issues

WHAT'S INCLUDED

• DEMO workbook with fictional example records

• CLEAN workbook for your own records

• Quick Start PDF, README, one-business licence and 10 CSV source-data backups

• 19 worksheets total: 12 visible workflow sheets and 7 hidden support sheets

• 2,585 formulas per workbook, 44 dropdown validations, 21 conditional-formatting rules and 4 charts

The DEMO names and numbers are fictional examples, not customer results or a revenue forecast. This is a record-keeping workbook. It does not promise subscriber growth, sponsor bookings or revenue, value an audience, set prices, or provide business, tax, legal, financial or accounting advice.
