A better way to buy B2B newsletter advertising

Verified subscriber counts. Transparent open rates. One insertion order across your entire campaign.

Without Inbocks

Buying newsletter ads doesn't scale

Fragmented inventory

Dozens of newsletters, each with its own rate card, booking process, and point of contact. Scaling means more spreadsheets, not more reach.

Unverified data

No way to confirm subscriber counts, open rates, or audience quality before you commit budget. You're buying on trust alone.

Too many contracts

Every placement requires a separate IO, invoice, and reporting workflow. Three newsletters means three of everything.

With Inbocks

One network, one IO, verified data

01

One network

Curated B2B newsletters in a single searchable directory. Filter by vertical, audience, reach, and format — then book in clicks, not email threads.

02

Verified sends

Every publisher submits transparent subscriber data, open rates, and audience breakdowns. No more guessing whether the numbers are real.

03

One IO

A single insertion order covers your entire campaign across multiple newsletters. One invoice, one report, one relationship.
