Affiliate-Marketing Policy Guide

Kit for affiliate marketing: the original-content rule and the 70–80% guidance.

Kit allows affiliate marketing, but it wants the creator's own business, expertise, research, or content to remain the reason the audience is receiving the email. The practical question is not simply whether an affiliate URL can be inserted. It is whether affiliate promotion remains secondary to original content.

Current StackEvidence verdict

Kit can support an affiliate-funded editorial publication when original content clearly remains primary.

That is stronger than saying “Kit allows affiliate links.” We gave Kit an actual representative sample of the type of comparison email StackEvidence expects to send, and a Product Specialist reviewed it against the current policy.

Accepted sample

StackEvidence editorial model

Kit reviewed our representative independent software-research and comparison draft and said it appeared primarily editorial, with affiliate links incorporated into the broader content and disclosed.
Not a fit

Affiliate-only publishing

Kit does not allow accounts that are 100% affiliate-based or primarily exist to promote or sell other tools, software, and third-party offers.
Separate opportunity

Kit affiliate program

Kit's affiliate program can be evaluated separately from using Kit as an ESP. Its current terms are materially more compatible with evidence-first publishing than agreements that prohibit legitimate competitive criticism.
Current interpretation: Kit is a viable production-ESP candidate for StackEvidence's planned editorial model, provided our actual sending continues to resemble the reviewed sample and remains compliant with the current Acceptable Use Policy.
The public rule

Kit wants affiliate marketing “sprinkled into” a real creator business.

Kit's current affiliate-marketing guidance centers on one main factor: the sender needs their own business or content outside of affiliate promotion.

Your own content must exist. The account should provide useful material that would still have a reason to exist without the affiliate commission.
Affiliate links must be disclosed. Readers should understand that a link may lead elsewhere and that the sender can receive compensation.
Affiliate promotion should be secondary. The third-party offer should support the content rather than replace the content.
Roughly 70–80% own content. Kit's published guidance uses approximately 70–80% for the sender's own products, services, expertise, and content.
Roughly 20–30% affiliate content. Kit uses approximately 20–30% affiliate-related content as the secondary portion of the message.
Some affiliate topics remain prohibited. Kit restricts certain higher-risk affiliate categories even when the sender otherwise has a legitimate business.
Treat 70–80 / 20–30 as operational guidance, not a mathematical loophole. A message should not be padded with filler merely to make a commission-first promotion appear to pass a percentage test.
StackEvidence's direct sample review

We did not rely only on the generic 70–80% article.

Kit Verification asked us to create a representative draft showing what our real audience would receive. We created that draft inside the account without sending it and asked Kit to review the actual content model.

Human Product Specialist review · October 6, 2026

The representative StackEvidence sample passed the content-model review.

The draft represented independent software research and comparison content, including the way affiliate-related material would be incorporated into the broader editorial message.

Kit's Product Specialist said the sample appeared primarily focused on independent editorial research and software comparison, with affiliate links incorporated as part of the broader content rather than being the sole purpose of the email.

The response also noted that the affiliate relationship was clearly disclosed and confirmed that Kit allows properly disclosed, responsibly used affiliate links.

Kit then told us we could continue sending emails while ensuring the content, subscriber-collection methods, and overall account activity continue complying with the Acceptable Use Policy.

Evidence boundary: this confirms the representative content model we showed Kit. It is not permission to change the account later into a commission-first affiliate-offer operation.
How to interpret the percentage guidance

Think in terms of substance, not merely counting URLs.

Earlier human guidance from Kit's Verification team told us the roughly 70–80 / 20–30 guideline is considered per email. The later sample review provides a more useful real-world example of what compliant execution can look like.

Original analysis Research, explanation, comparison logic, limitations, pricing context, and useful recommendations should make up the substance of the message.
Affiliate material Commercial links can support the analysis without becoming the reason the email exists.
Disclosure The commercial relationship should be obvious enough that the reader understands compensation may occur.
Multiple links do not automatically fail. Link count alone is a weak proxy for whether the actual substance of the message is editorial or promotional.
One link can still be too promotional. A short message whose only purpose is driving a sale can remain affiliate-heavy even if it contains a single URL.
Account behavior matters too. Kit evaluates the broader account, subscriber collection, complaint signals, and ongoing compliance rather than one isolated ratio forever.
What fits and what does not

The business model matters more than whether an email contains an affiliate URL.

Stronger fit

Evidence-based comparison

A detailed software comparison that helps a reader choose between products and contains disclosed links as one part of the analysis.
Stronger fit

Educational newsletter

A useful email teaching a process, strategy, or workflow that recommends a relevant product where it genuinely helps.
Poor fit

Third-party-offer feed

An account with little independent content whose recurring purpose is sending links to software offers, launches, deals, or other products primarily to earn commission.
The percentage is not the only rule

Some topics remain restricted even when affiliate content is a minority of the email.

Kit's current affiliate-marketing guidance specifically identifies certain categories that it does not allow through affiliate links.

Get-rich-quick software Kit specifically restricts affiliate links associated with get-rich-quick style software.
Certain education offers Kit lists education-related affiliate links among restricted categories in its current guidance.
Loan offers Loan-related affiliate links fall into a restricted category.
Online pharmacy offers Online-pharmacy affiliate content is likewise restricted.
Passing the original-content test does not override subject-matter restrictions. The content model and the promoted category both need to fit Kit's current policy.
Account verification and monitoring

Kit evaluates more than the draft itself.

The sample-review process also reinforced that healthy production use depends on permission-based subscriber collection and normal account-quality signals.

Subscriber collection The account should be able to explain where subscribers came from and why they expect the emails.
Bounce behavior Elevated bounces can contribute to manual review or account concerns.
Spam complaints Complaint signals remain important even when the content itself falls within the affiliate-content guideline.
Unsubscribe behavior Subscriber reaction can indicate whether communication matches expectations.
Ongoing monitoring A previously acceptable sample does not remove Kit's ability to review later account activity.
Policy changes Operational guidance should be rechecked if Kit materially changes its Acceptable Use Policy or affiliate-marketing rules.
Separate relationship: Kit's affiliate program

Kit also pays affiliates to recommend Kit itself.

Using Kit as your email provider and joining Kit's affiliate program are separate decisions. The latter creates an additional agreement governing Kit-specific referral links.

PartnerStack Kit currently operates affiliate payments and program administration through PartnerStack.
50% for 12 months Current standard referrals earn 50% of eligible Kit customer revenue during the first 12 months.
Bronze Affiliates meeting the current 10-referral status threshold can earn 10% recurring revenue after the first year while status is maintained.
Silver The current 50-referral threshold corresponds to 15% recurring commission after the customer's first 12 months.
Gold The current 100-referral threshold corresponds to 20% recurring commission after the customer's first 12 months.
90-day attribution window Kit's current governing terms use a 90-day window with attribution generally going to the last qualifying Kit affiliate link clicked.
Honest opinions required Affiliate statements about Kit must reflect honest opinions, beliefs, or experiences and cannot be false, misleading, or unsupported.
Disclosure required Kit requires a clear material-connection disclosure when a Kit affiliate link is used.
No program link yet StackEvidence has not inserted a Kit affiliate link on this page.
Editorial compatibility looks better than several competing programs. Kit's current public affiliate agreement requires truthful and honest statements but does not contain the same broad public competitor- recommendation prohibition that raised our concern with some other vendors.
Affiliate-program rules still matter

Good commission economics do not mean the program is unrestricted.

Self-referrals are prohibited. Purchases made through your own referral relationship do not qualify for affiliate fees.
Cashback is prohibited. Affiliates may not rebate commission or otherwise pay customers to generate qualifying actions.
SMS promotion is prohibited. Kit's current affiliate terms prohibit sending program links or associated marketing messages by SMS or text.
Unsolicited bulk email is prohibited. Permission-based email promotion must not be confused with spam or unsolicited bulk messaging.
PPC has restrictions. Kit restricts bidding on its trademarks, direct linking from PPC, and other paid-search behavior unless written permission applies.
Approved domains matter. Domains using the affiliate link are expected to be listed in the affiliate profile.
A durable Kit affiliate-content model

Build the email around value first and attach monetization second.

1
Research Start with a genuine reader problem and useful original evidence.
2
Teach Make the email valuable before considering the commercial link.
3
Recommend Mention the product only where it is relevant to the analysis.
4
Disclose Make any commercial relationship understandable to the reader.
5
Monitor Keep actual account activity consistent with subscriber expectations and Kit policy.
Before choosing Kit

Ask whether your affiliate business actually resembles the model Kit allows.

Do you create substantial original content? A real editorial, creator, education, or business layer is central to Kit's allowed affiliate model.
Are affiliate offers contextual? The recommendation should relate naturally to the content rather than replace it.
Can you disclose clearly? Both Kit's ESP guidance and affiliate-program terms emphasize transparent commercial relationships.
Is the niche permitted? Certain high-risk affiliate categories remain restricted regardless of content percentages.
Do you need automation? Policy fit is separate from whether Kit Free, Creator, or Pro contains the workflow you require.
Would the email still help without the link? This is a useful practical test for whether the publication remains editorially valuable rather than commission-first.
Continue the research

Policy fit is only one part of the Kit decision.

Evidence standard

This page combines public rules with a direct review of the actual content model.

The public policy establishes Kit's general boundary. The Verification team's earlier response explained the percentage guidance. The October sample review is stronger operational evidence because Kit evaluated a representative StackEvidence message rather than a hypothetical description alone.

Kit Product Specialist sample review October 6, 2026 human review of StackEvidence's representative software-research and comparison draft.
Kit — What Affiliate Marketing Is and Isn't Allowed Current public 70–80% original / 20–30% affiliate guidance and restricted affiliate categories.
Kit — Acceptable Use Policy Current governing content and account-use boundary for Kit customer accounts.
Kit — Affiliate Program Current 50% first-year commission and Bronze, Silver, and Gold recurring-revenue structure.
Kit — Affiliate Program Terms Current attribution, disclosure, honest-opinion, spam, self-referral, PPC, and program-use restrictions.
Commercial transparency

Kit's unusually strong affiliate economics do not control our ESP recommendation.

This page contains no Kit affiliate link. Kit's policy fit, functionality, pricing, and suitability are evaluated separately from what StackEvidence could earn by referring a Kit customer.

Current StackEvidence position: Kit has reviewed a representative version of our intended affiliate-supported editorial email model and said we may continue sending under the current policy. That materially improves its production suitability for StackEvidence. We will still maintain the original-content boundary, clear disclosures, permission-based subscriber acquisition, and ongoing compliance.
