Newsletter adoption is rising as marketers look for a channel they own. With 58% of marketers now running one, the inbox is becoming the alternative to algorithm-driven feeds.
The inbox is the one audience an algorithm cannot take away from you overnight.
While the rest of marketing fights for scraps of attention inside someone else's algorithm, the email newsletter has quietly become the channel worth holding. New data shows newsletters are now the second most-used email type, with 58% of marketers running one, up from 46% in 2024.
The pull is simple. A newsletter is curated content from a trusted source, landing in a place the recipient chose to let you into. It is a break from the algorithm-driven feed, and it is one of the few channels where you own the relationship rather than rent it from a platform.
The performance is there too. Average open rates sit around 20.73%, but the top 10% of senders reach 44.02%, more than double. Automated, behaviour-triggered emails run at 30.63% opens and 7.39% clicks against averages of 20.73% and 2.27%. The gap is list quality and segmentation, not luck.
Why it matters
As search traffic gets intercepted by AI answers and social reach stays at the mercy of a feed, the channels you own are the ones that hold up. A subscriber list is land you hold the title to. Nobody changes the rules on you and wipes it out in a quarter.
The one trap is measurement. Privacy protections now inflate open rates, with some emails marked opened without a human ever seeing them. Open rate is no longer a clean read on attention, so the senders who win measure clicks, conversions and revenue per email instead.

What to do about it
Build the list as an asset. A subscriber is a direct relationship that survives the next algorithm change. Treat it that way.
Stop trusting open rate alone. Privacy changes have made it noisy. Measure clicks, conversions and revenue per email.
Segment before you scale. The top performers are not sending more. They are sending to the right people.
Lean into automation. Behaviour-triggered emails outperform broadcasts by a wide margin. Set them up once and they keep working.
Give people a reason to stay subscribed. A newsletter earns the inbox by being worth opening, not by sending more often.
The businesses that come out of this shift in good shape will be the ones who spent the time building an audience they own, while everyone else kept renting reach.
