Buffer

Based on current rankings and subscriber data, here are the marketing newsletters with real, sizable audiences and consistent recommendations across multiple sources:

Daily News & Industry Updates

Marketing Brew — The clear leader in this category. It's the single best daily newsletter for general marketing news in 2026, delivering a 5-minute briefing on advertising, social media, and brand strategy, and sits inside the Morning Brew network, which Business Insider acquired in October 2020 at a reported $75 million valuation, growing to over 4 million subscribers.

Stacked Marketer — The top daily newsletter for hands-on performance marketers, with 90,000+ subscribers and a 7-minute read format, covering paid social, paid search, e-commerce, and SEO updates.

TLDR Marketing — Part of the 13-edition TLDR network (7.2M+ total readers), offering a 5-minute daily digest of growth-marketing, SaaS, ad-platform, and analytics news, free and ad-supported.

Tactical Growth & Strategy

Demand Curve — Best for growth marketers seeking tactical playbooks (100k+ subscribers, 50%+ open rate, free, weekly).

Marketing Examples by Harry Dry — A cult favorite for copywriting. It's a super popular newsletter that rounds up real-world examples of impactful marketing campaigns, with each edition including three short examples, two copywriting tips, and one favorite tweet — voted as the "#1 marketing newsletter" and boasting over 130,000 subscribers.

SEO Specific

Moz Top 10 — Best for SEO professionals tracking algorithm updates (500k+ subscribers, free, bi-weekly).

Social Media & Creator Economy

According to Buffer's roundup, the top picks are Link in Bio by Rachel Karten for tactical social media, ICYMI by Lia Haberman for creator economy news, Why We Buy by Katelyn Bourgoin for marketing psychology, Considered Chaos by Eugene Healey for brand strategy, and Creator Science by Jay Clouse for creator business frameworks.

Broader Business Context

The Hustle — While not exclusively a marketing newsletter, it delivers daily business and tech news that every marketer should know — understanding broader market trends, funding news, and tech shifts helps marketers make better strategic decisions.

My recommendation on how to start

Rather than subscribing to everything, Buffer's advice is solid: start with three or four that serve different purposes — one for news, one for strategy, one for skills, or inspiration. Read them consistently for a month, then keep the ones you're actually opening.

A practical starter stack: Marketing Brew (news) + Demand Curve (tactics) + Marketing Examples (craft/copywriting) covers the bases most marketers need without overwhelming your inbox.

For marketers aiming to stay ahead, the must-read newsletters cover growth, SEO, social media, content strategy, and behavioral insights, including Demand Curve, Marketing Brew, Link in Bio, and Creator Science.
