Substack is experimenting with three new sponsorship formats that do not just show a brand around content: they directly fund part of the experience offered to readers. With Upgrade, a brand offers a month of paid subscription to free subscribers. With Unlock, she pays the author to open an article normally reserved for paying members. With Masthead, she supports an editorial destination bringing together several creators around a theme.
For independent creators, newsletters and media, the idea is important: a sponsor can bring value before asking for attention. But it is not yet a program open to all. Substack is currently working with small groups of Bestsellers publications and brands, and activation of a Creator Kit does not guarantee any campaign.
Information verified on 12 October 2026. The official announcement was published on October 8 by Substack. The platform does not provide a global calendar, standardized tariffs or country list for these three formats.
What Substack has officially announced
Substack presents Upgrade, Unlock and Masthead as the next phase of its native sponsorship program. The stated objective is to help participating publications gain more and reach new readers, while allowing brands to measure something other than impressions or clicks.
The platform doesn't start from scratch. She announced a first phase of her sponsorship program in June 2026 and created the Creator Kits to help certain publications present their audience to brands. On October 8, Dan Robbins, Head of Brand Partnerships at Substack, detailed the three new formats and confirmed that the company was still testing them with small groups.
Participation is optional. An eligible publication may activate its Creator Kit to signal its interest, but the relationship is currently managed by the Substack team. Official documentation indicates that Creator Kits are currently available for Bestsellers publications or with at least 100 paid subscribers. They are not public: only brands integrated into the program and linked by Substack can consult them.
Substack also adds Kantar studies for some large-scale campaigns. These surveys must measure the development of the reputation, perception and consideration of a mark. This does not replace conversion data, but clearly indicates the direction: the platform wants a community's trust to be recognized as a measurable value, not just as a volume of displays.
Upgrade, Unlock and Masthead: how all three formats work
Upgrade: the brand offers a paid month
With Upgrade, a brand finances a month of paid access for free subscribers of a publication. Readers can discover the entire premium experience without bearing the cost of the first month, then decide to become paid subscribers when the sponsored period ends.
This format can reduce significant friction: an interested reader sometimes hesitates to pay because he does not yet know whether depth, rhythm or archives justify subscription. The sponsor finances this essay. In exchange, he associates his name with a concrete advantage rather than an advertising interruption.
However, the crucial question will be conversion after the period offered. A free month of lasting value for the author only if the readers clearly understand what they will then receive, at what price and how the subscription will continue. The arrangements for renewal and identification of the sponsor must remain fully legible.
Unlock: a paid article becomes accessible to all
Unlock allows a brand to finance the opening of an article normally placed behind a paywall. The author is paid for his work, while the content can reach readers who are not yet subscribed.
The format is particularly interesting for a reference article, survey, guide or interview whose value can convince new readers. The sponsor not only pays to appear next to the text: he pays to temporarily remove the access barrier.
This logic better protects editorial value than a multiplication of banners, provided that the choice of article remains consistent. A publication specializing in personal finance would quickly lose the confidence of its audience if a brand influenced the conclusions of the text that it makes free. Funding for access should not become public funding.
Masthead: a thematic editorial destination
With Masthead, a brand brings together several authors and creators around a theme in a dedicated destination on Substack. The platform compares the result to a digital magazine: a sign can bring together guides, a hotel brand supporting travel stories or a technology company selecting analyses on the future.
This format exceeds placement in a particular newsletter. It allows a brand to rely on voices that have already been followed instead of zeroing its own publication. For creators, opportunity can give access to a complementary audience and collective collaboration. It also raises more questions about the selection of authors, editorial direction, reuse rights and the visibility given to each contributor.
Real change: sponsor funds experience
Classic digital advertising often buys a space or an interruption: a banner, a pre-roll, an insert or a message inserted in the stream. The formats presented by Substack attempt another logic. The sponsor finances an identifiable benefit for the reader: discover a subscription, access an article or explore a thematic folder.
For VIFLYthis is the most interesting editorial signal:
This approach does not automatically render a collaboration virtuous. A brand can always be wrongly chosen, a commercial mention may lack clarity and a sponsored folder may become promotional. But the starting point changes: the question is no longer only "how many people will see the logo?", but also "what does this brand actually allow readers to get?".
This development complements the new brand partnerships recently presented by YouTube. Platforms are increasingly seeking to organize the business relationship, present the audience, measure results and guide the use of content. In both cases, the creator must be able to explain its value without reducing it to its number of subscribers.
It also shows why subscriptions should not be considered as the only answer. Article VIFLY on new beehiv rates already recalls that a newsletter must measure the real value of its platform and audience. Sponsoring may become a supplementary income, but it also adds commercial, contractual and editorial work.
Two practical examples for creators and freelancers
Advisory newsletter opens best guide
Imagine a consultant who publishes a weekly newsletter for small businesses. His most in-depth guide explains how to prepare a digital visibility audit and is normally in the pay offer.
A productivity tool company proposes to finance an Unlock. The article becomes accessible to all during the campaign, the consultant is paid and new readers discover the quality of her work. To preserve trust, it clearly indicates partnership, retains freedom of content and refuses any changes that would turn the guide into a commercial demonstration.
After reading, the course must not end. One LinkHub VIFLY may refer to the newsletter, other resources, the accompanying offer and the contact form. The sponsor finances the discovery; the designer retains a destination that she controls to transform this discovery into a lasting relationship.
Several creators build a thematic folder
Now let's take a group of a photographer, a local guide and a responsible tourism author. A baggage brand wants to finance a Masthead destination around the slow trip.
The project may be relevant if each author retains his/her voice, the theme corresponds to his/her audience, and rights are defined prior to production. The contract must specify the remuneration of each, the deliverables, the duration of operation, the countries, the advertising uses, the possibility of assembly and how the mark will be identified.
A good one Media Kit VIFLY helps to present the positioning, platforms, references and collaboration formats. It does not guarantee the signature of a partnership, but reduces the time required for a brand to understand the relevance of the creator.
These examples show an essential distinction: sponsoring is not just an income related to an audience. It is an exchange of value, rights and reputation. The prize must pay for creation, but also access to confidence built with the community and possible additional uses of content.
Nuances, availability and vigilance points
First shade: the three formats remain in the test phase. Substack talks about small groups of Bestsellers publications and brands. Enable your Creator Kit expresses interest; This does not create any right to a campaign or predictable income. Publications that do not yet have Bestseller status or 100 pay subscribers do not currently have this tool according to the documentation consulted.
Second shade: Substack does not publish a universal tariff schedule. Amount, duration, rights and obligations are likely to depend on each campaign. A creator should therefore not build financial forecasts from a still experimental format.
Third grade: no detailed international availability is announced. The official article presents a global orientation, but does not list countries, schedule of deployment for France, or fiscal or contractual conditions specific to each market. The actual availability must be verified in the publication dashboard.
Fourth vigilance: offering a month or opening an article may blur the perceived value of the subscription if the transaction is too frequent. Paid members should not feel that the best content becomes systematically free. The creator must explain what the sponsor finances and what the subscription continues to bring.
Fifth vigilance: reuse rights must be separated from mere publication. A brand that finances an article does not automatically obtain the right to transform it into advertising, to mount it, to exploit it in several countries or to use the image of the creator indefinitely. Each extension must be explicitly negotiated.
Finally, transparency is not just a small logo. In France, commercial content must be unambiguously identifiable. The mention must be visible, understandable and placed so that the reader knows the relationship before interpreting the content. A brand can finance access; It must not become invisible when it influences experience.
What should you do now? The VIFLY action plan
- Clarify your editorial proposal. Define the subject, audience and regular value of your publication. A mark must include in a few lines why your audience reads you.
- Prepare honest data. Gather the number of subscribers, the opening rate, active readers, geography and examples of high performance content. Present the context rather than an isolated number.
- Build a verifiable Media Kit. Use it Media Kit VIFLY to organize your positioning, platforms, references and collaboration formats.
- Set your limits before the proposal. List the rejected sectors, the subjects on which you maintain absolute independence and the rights you do not grant without additional remuneration.
- Create three simple offers. For example: sponsored opening of a resource, series of two editions or collective thematic dossier. For each, specify content, delay, distribution, measurement and rights.
- Measure the useful effect. Follow the new readers, registrations, fee conversions, answers and qualified requests. Impressions alone are not enough to establish the value of the partnership.
- Protect the direct relationship. Do not hand over your entire audience to a platform or sponsor. Centralize your resources and next actions on a path you can maintain.
- Diversify without dispersing. A sponsorship complements subscriptions, premium content, services or reservations. VIFLY page dedicated to the monetisation of a hearing allows to compare these models from actual demand.
The right objective is therefore not to add an advertiser to each publication. It is to design collaborations where the reader receives a clear benefit, the creator retains his credibility and the brand understands what it finances.
