Newsletter inventory is worth several times what the equivalent web traffic fetches. A 2,000-subscriber newsletter can often out-earn a site doing 50,000 monthly pageviews.

Why the premium is real

Attention, not incidental exposure. Someone opening an email chose to. Someone loading a page is there for the article and treating the ads as scenery.

No ad blocking. Email clients do not run blockers. Your delivered impressions are your actual impressions.

Trust transfers. A recommendation in your own voice inside your own newsletter carries endorsement weight a banner cannot.

Scarcity. You send weekly and have one slot. There is no infinite inventory to discount against.

The maths

The rough industry benchmark is $20–50 CPM on opens for a niche newsletter, versus $2–15 for display.

With 2,000 subscribers and a 45% open rate, that is 900 opens. At $30 CPM, roughly $27 per send. Over four sends, about $108 a month.

That understates it for a tightly focused list. Niche B2B newsletters regularly reach $80–150 CPM. If your subscribers are professionals who buy things for work, price much higher than the general benchmark.

Quote per send, not per subscriber

"$150 per issue" is easier to say yes to than a CPM calculation, and it protects you when open rates fluctuate.

Offer a discount for a block of four: $500 for a month rather than $600. It gets you predictable revenue and saves selling the same slot four times.

What to sell

A text placement. A headline, two or three lines, and a link. Highest performing and the least work for everyone. No design needed, so small sponsors can actually buy it.

A short sponsored section. Two or three sentences in your voice, clearly labelled. Higher rate, more effort, and you should retain approval over the copy.

A logo or banner. Lowest performing. Images are frequently blocked by default in email clients, so a substantial share of your audience sees nothing at all. Discourage this.

Track clicks properly

Email has no impressions you can trust — open tracking is unreliable and getting worse as clients pre-fetch images. Clicks are the number that matters.

Use a tracked link so you can report actual clicks per send. That single number is what a sponsor renews on.

Placement in the email

Top, before the content: highest clicks, most intrusive. Charge most.

After the first section: best balance, and what most newsletters use.

Bottom: meaningfully fewer clicks. Only sell it as an add-on.

What to tell a sponsor before they buy

Be straight about the size of the list. Trying to make 2,000 subscribers sound like more is transparent and it poisons the relationship.

A better framing: "2,000 subscribers, 45% open rate, and they are all [very specific description]. Last sponsor got 38 clicks from one send." Specific and verifiable beats impressive and vague.
