Stacked Marketer

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.

The "best" marketing newsletter depends entirely on your daily role—whether you are a performance marketer running paid ads, a content strategist, a startup founder looking for growth, or a social media manager.

The absolute top marketing newsletters that industry practitioners actually open, read, and use are categorized below by their focus areas.

1. The Best Daily Newsletters (To Stay in the Loop)

These are your daily morning reads to keep you informed on industry shifts, algorithm changes, and major brand campaigns without taking up too much of your time.

• Marketing Brew
  • The Vibe: Witty, engaging, and highly professional.
  • Best For: Brand marketers, agency professionals, and advertisers who want to stay on top of the latest ad tech, campaign trends, and media news.
  • Why people read it: Part of the Morning Brew family, it translates dry industry reporting (like changes in privacy regulations or Super Bowl ad reviews) into highly entertaining daily digests.
• Stacked Marketer
  • The Vibe: No-nonsense, highly tactical, and fast-paced.
  • Best For: Media buyers, DTC (Direct-to-Consumer) brand owners, and digital marketers working heavily with paid social (Meta/Google Ads), SEO, and e-commerce.
  • Why people read it: It delivers the latest platform updates, algorithm changes, and actionable marketing tips in a 5-to-7-minute read. If an ad platform breaks or introduces a new feature, Stacked Marketer is usually the first to break down what it means for your wallet.

2. The Best Growth & Startup Playbooks

If you are looking for long-form, highly detailed case studies and step-by-step guides on how to scale a business, these are the gold standards.

• The Growth Newsletter (by Demand Curve)
  • The Vibe: Masterclass-level deep dives.
  • Best For: Startup founders, B2B marketers, and growth operators.
  • Why people read it: Demand Curve doesn't write high-level theory. Instead, they break down exactly how modern tech companies acquire users, optimize landing pages, and scale acquisition channels. Expect visual teardowns and frameworks you can steal for your own business.
• Lenny’s Newsletter (by Lenny Rachitsky)
  • The Vibe: Extremely thorough, community-driven, and authoritative.
  • Best For: Product managers, growth marketers, and Go-To-Market (GTM) leaders.
  • Why people read it: Boasting over 1 million subscribers, Lenny’s Newsletter is the most respected publication for Product-Led Growth (PLG). He answers real reader questions with in-depth interviews and data-heavy breakdowns of how companies like Airbnb, Figma, and HubSpot scaled.

3. The Best for Copywriting & Psychology

Marketing is ultimately about understanding humans and writing things that make them take action. These newsletters focus heavily on the creative and behavioral side of marketing.

• Marketing Examples (by Harry Dry)
  • The Vibe: 100% visual, zero fluff.
  • Best For: Copywriters, landing page designers, and conversion rate optimization (CRO) specialists.
  • Why people read it: Harry Dry is famous for his side-by-side, visual comparisons of "bad copy vs. good copy". Every newsletter is incredibly short, visually satisfying, and teaches you a concrete copywriting or marketing principle in under two minutes.
• Science Says (formerly Ariyh, by Thomas McKinlay)
  • The Vibe: Evidence-based, academic, yet incredibly practical.
  • Best For: Data-driven marketers, strategists, and psychology nerds.
  • Why people read it: McKinlay sifts through thousands of peer-reviewed academic studies on consumer behavior and packages the findings into 3-minute newsletters. Instead of relying on marketing "gurus," you get science-backed evidence on exactly what colors, fonts, pricing structures, and messaging actually convert.

4. The Best for Social Media & Content

If you make a living creating content or managing brand channels, this is the most active and supportive corner of the marketing internet.

• Link in Bio (by Rachel Karten)
  • The Vibe: Empathetic, culturally plugged-in, and highly relatable.
  • Best For: Social media managers, content creators, and brand directors.
  • Why people read it: Written by the former head of social at Bon Appétit, this Substack is the ultimate community for the people "who actually press post" on brand accounts. It features interviews with the masterminds behind viral brand accounts, breakdowns of fast-moving internet trends, and career advice for managing social media burnout.
