Recently at our INMA Product & Tech Advisory Council, we dove into the ever-evolving world of newsletters. It’s clear many have made huge strides on a number of fronts, and it’s paying off. 

Here are some strategies that are working: 

• From pop-ups to inline sign-ups: Seamless signup flows are driving higher opt-in rates.

• Inbox decluttering: Generic campaigns are being reduced in favour of (sometimes personalised) send schedules to respect readers’ attention.

• Higher-quality ads via GAM integration: Better targeting, better yield, and a smoother reader experience.

• Next-gen personalisation experiments: Dynamic content blocks tailored to individual interests are starting to land.

All of these fixes have boosted metrics. Open rates are up, unsubscribe rates are down, and ad RPMs are looking healthier. 

But here’s my British pessimistic side poking through in: I’m not convinced this newsletter renaissance will last beyond the short term.

Here’s why:

Major e-mail platforms like Apple Mail and Gmail increasingly silo newsletters into secondary and tertiary tabs within a user’s inbox. Even a sparklingly relevant e-mail with a killer headline can vanish in that abyss. I’ve written about that before here. And (again) this may be bad for us, but as a consumer it’s incredibly helpful.

In addition to this, three emerging forces are converging to reshape how audiences consume content:

1. Audio: I’m a firm believer that we are moving into an audio-first world. Imagine a  voice-first experience that let readers listen on the go, without inbox overload.

2. Personalisation: A trend that we’re already seeing gives consumers a highly prioritised inbox, not just by the time an e-mail was sent.

3. Summarisation: We don't read every word of every e-mail. Just as summarisation has come for articles, it’s coming for e-mails, too. 

These three are likely to change a user’s experience all the more. In fact, new tools on the market, such as Huxe by the developers of Google’s Notebook LM, are already doing just that.

Together, these trends point toward a future where newsletters as we know them may feel antiquated. Early audio summaries and AI-driven personalisation are still finding their feet, but directionally, they promise a more frictionless, on-demand experience than e-mail ever could.

For now, it makes sense to keep optimising newsletters. But I’d also recommend you start exploring audio summaries, adaptive content feeds, and next-level personalisation. Because while our inboxes remain central today, the inbox of tomorrow could be our ears.
