Open rates are lying to you (here's what to track instead)
The coffee’s gone cold on your desk, Monday morning light slanting through half-drawn blinds, and you’re staring at a dashboard that says 43% of last Thursday’s send was opened — except you know for a fact your sponsor link barely cleared 2% clicks, and nobody replied.
Apple Mail Privacy Protection inflated your open rate by 20 points and you didn’t notice
The metric you’ve relied on for years now tracks image preloads, not human attention.
Apple’s Mail Privacy Protection preloads tracking pixels whether someone reads your email or not, making reported open rates look inflated without reflecting real engagement. Open rate measures attention, but revenue and retention measure value. If your newsletter hit 40% last month but sponsor CTR stayed flat and unsubscribes climbed, you’re looking at phantom opens — automated systems firing pixels while real readers scroll past.
Open rate is a leading indicator, not a revenue indicator, and if your open rate is 28% but your revenue per subscriber is growing, you’re winning. The operators making money in 2026 stopped treating open rate as the headline metric months ago. Click-through rate — unique clickers divided by delivered emails — is now the gold standard for engagement. A 3% to 8% click rate on total subscribers is strong, and even a 0.5% reply rate can indicate a highly engaged audience. Track those two, layer in revenue per send, and you’ve got a dashboard that actually tells you if Thursday’s edition moved the business forward.

Click-to-open rate tells you if your content converts interest into action
Click-to-open rate — unique clickers divided by unique openers — shows how well your content converts interest into action. If 1,000 people opened and 80 clicked, that’s an 8% CTOR. Anything above 5% means your writing and link placement are working. Below 3% and you’ve got an attention problem inside the email itself — weak hooks, buried links, or a mismatch between subject line promise and body delivery. Segment your last ten sends by CTOR, find the two highest, and reverse-engineer what made readers act. That pattern is your new content template.
READER QUESTION
What CPM should a 20,000-subscriber newsletter actually charge in 2026?
Mid-sized newsletters with 20,000 subscribers typically charge between $500 and $3,000 per placement, with CPMs around $20 to $50 depending on niche and engagement, and a $35 CPM translates to $700 per placement. B2B newsletters in specialized industries often command CPMs of $50 to $100+, while broader consumer newsletters sit closer to $15 to $35. If you’re showing a 40%+ open rate and 3% to 5% sponsor click-through, you can justify the upper end of that range even without a massive list. The operator who sent this question was charging $300 flat. We walked through the maths — $35 CPM on 20k is $700 — and she repriced her next sponsor at $650. It closed in two emails.

Why beehiiv publishers are adding direct sponsorships on top of ad networks
Many beehiiv publishers in 2025 took a multi-layered approach to ad sponsorships, using beehiiv’s Ad Network as the foundation for consistent opportunities with predictable payouts, then forging direct partnerships with relevant advertisers to boost earnings even further. The ad network handles fill rate and keeps the calendar predictable. Direct deals layer premium CPMs and multi-send commitments on top. More publishers are seeing multi-channel campaigns and long-term collaborations, with sponsors buying a series of newsletters, a special edition, a podcast episode, and a live event as one integrated campaign. If you’re relying on one revenue stream, you’re leaving money in the sponsor’s budget that someone else will take.
