Audience research
Part of Newsletter monetisation audience research: a method
Newsletter monetisation competitor research without copying
Newsletter monetisation competitor research: compare public paid offers and sponsor disclosures without copying or guessing subscriber numbers.
Use newsletter monetisation competitor research to compare public propositions and operating evidence, not to manufacture market share or subscriber intelligence. Define the question, candidate universe and observation date before opening pages, then preserve source facts separately from interpretation.
What to take away
- Define the decision, candidate universe and observation date before opening any competitor pages.
- Separate register facts, first-party claims, independent evidence and editorial interpretation into four distinct columns.
- Public availability does not grant reuse rights, so check site terms, robots instructions and licences first.
- If lawful access cannot support a fair comparison, narrow the question or stop rather than guess.
Set the boundary
- Name the decisionpositioning, offer design, sponsor evidence, cancellation journey or another bounded choice.
- Define newsletter eligibility, England geography and observation period.
- Publish inclusion and exclusion rules, including lapsed sites, personal blogs, non-email publications and inaccessible paid material.
- Declare any affiliate, supplier, employer or investment conflict.
Find comparable newsletters and monetisation evidence
Use Google Search with a topic and place, then check Substack's public discovery pages and signup pages to identify candidates. The Mill is a named newsletter candidate to assess for an England-focused comparison; include it only if it meets your stated scope. A signup page hosted by beehiiv, Ghost, Kit or Mailchimp identifies a publishing platform, not the publisher's audience size.
- Record each candidate's public free or paid signup route and any published tier price and benefits.
- Note visible sponsorship or affiliate disclosures and any public media kit or sponsor terms.
- Record the issue format, observed commercial offer and capture date.
Treat prices and sponsor terms as publisher claims, not validated sales evidence. Leave unpublished sponsor rates, paid conversion and subscriber totals unknown rather than estimating them.
An England registered office is not proof of an England audience. Companies House provides a searchable company register and warns that it does not verify filed information. Record legal identity and filing status as register facts only.
Search the register by company name or number, then open the filing history and confirmation statement. Check robots.txt at the site root before any automated collection.
Use four evidence columns
- Register fact:company number, filing or trade-mark record, with source date.
- First-party claim:the operator's public description, offer or terms, quoted sparingly and linked.
- Independent evidence:an identifiable regulator decision or method-disclosed study.
- Editorial interpretation:the researcher's bounded conclusion and uncertainty.
First-party claim
- Company number and filing status from the Companies House entry, dated when checked
- The offer page wording on price and renewal, quoted briefly
Independent evidence
- Company number and filing status from the Companies House entry, dated when checked
- A method-disclosed study or regulator decision naming the operator or sector
Editorial interpretation
- Company number and filing status from the Companies House entry, dated when checked
- A bounded note that the public offer is clear, audience size unknown
A worked research record can start with The Mill: first test whether it meets the declared geography and newsletter criteria, then record the public signup route, any published paid offer and visible sponsor disclosure on the observation date. Leave its subscriber count and any unpublished sponsor rates unknown; the example demonstrates the method, not an audience estimate.
Do not turn a search position, follower count, review total, archive size or claimed subscriber figure into market share. A signup page can show a free or paid route, a published offer can show stated prices and benefits, and a dated issue can show its format and observed sponsorship; none establishes subscriber numbers or conversion. Save the exact page, capture date and geography, and mark unpublished audience information as unknown.

Respect access and rights
- Review public pages and editions received through an honest, permitted relationship.
- Do not bypass a paywall, impersonate a buyer, evade technical controls or solicit leaked analytics.
- Record site terms, robots instructions, licence and permitted reuse before automated collection.
- Summarise what is necessary; do not republish competing editions, lists or tables.
GOV.UK's copyright guidance explains permission, licensing and limited exceptions. The Intellectual Property Office's database-right page says database contents and original selection or arrangement can have separate protection. The governing UK statutes include the Copyright, Designs and Patents Act 1988, which provides limited fair dealing for criticism or review, and the Copyright and Rights in Databases Regulations 1997. Fair dealing is not a blanket licence to reproduce paid editions; quote only what the analysis needs and seek qualified IP advice when uncertain.
Protect people behind the pages
- Avoid collecting subscriber identities, email addresses, tracking identifiers or staff details not needed for the purpose.
- Separate a named business contact from permission to send marketing.
- Set access, retention, deletion and incident owners for the research file.
Where personal data is involved, the UK GDPR's purpose-limitation principle and the Data Protection Act 2018 are relevant: purposes must be specified and any reuse assessed. The ICO's purpose-limitation guidance explains this principle. Its electronic-mail marketing guidance addresses later promotional contact. Competitor analysis does not create a sales permission.
Do not collect personal data simply because it is visible on a public page.
Check commercial evidence honestly
- Identify whether an observed item is editorial, paid access, sponsorship, affiliate content or an owned offer.
- Preserve visible disclosure and the commercial relationship claimed, without guessing undisclosed terms.
- Treat testimonials and ratings as claims requiring provenance, not verified outcomes.
The CMA's reviews and endorsements collection covers genuine and accurate reviews and clear incentivised endorsements. For advertising disclosure, the Advertising Standards Authority (ASA) enforces the CAP Code, which requires marketing communications to be obviously identifiable. These rules help assess visible claims and disclosures; they do not establish that a particular newsletter's audience, reach or results are genuine.
If a disclosure is unclear, leave the commercial relationship as unknown rather than infer terms.
Close with a decision record
For each candidate, record eligibility, sources, unknowns, rights basis, evidence quality and the exact comparison field. Have privacy, IP, advertising, consumer, security, accessibility and commercial owners approve their own gates.
Before acting, confirm the bounded decision and the published inclusion rules with the observation period. Record source page, capture date and geography for every claim. Do not bypass paywalls or solicit leaked analytics. Avoid collecting subscriber identities or unnecessary staff details.
The final output should say what public evidence supports, what remains a supplier claim and what was not inspected. If a fair comparison needs paid or private material you cannot lawfully access, narrow the question or stop.
Common questions
How should a researcher handle an England registered office when assessing audience?
Treat it as a register fact only. It says nothing about where readers are. Record the legal identity and filing status from Companies House, but note that the register does not verify filed information.
What does the article say about using testimonials and ratings as evidence?
Treat them as claims that need provenance, not verified outcomes. The CMA's reviews and endorsements collection covers genuine reviews and clear incentivised endorsements, but it does not prove a newsletter's audience, reach or results.
When should competitor research stop rather than continue with estimates?
Stop if a fair comparison needs paid or private material you cannot lawfully access. Narrow the question or stop, and state what public evidence supports and what was not inspected.
