Part of Six separate legal questions to answer before marketing automation sends anything
Marketing automation advertising rules: six pre-send checks
Check marketing automation advertising rules in England before release, covering substantiation, qualifications, ad identity and automated copy changes.
Marketing automation advertising rules apply to the output people see, not merely the approved base template. Before release in England, examine every automated variant, inserted field, qualification and destination page as one communication. Keep evidence for the objective meaning a consumer is likely to take from it.
This checklist covers non-broadcast marketing and consumer-protection questions at a general level for teams sending into England. It does not test a live advert, and any actual campaign still needs review against the current CAP Code and the rulings of the Advertising Standards Authority.
What to take away
- Automated marketing rules apply to every variant a consumer sees, not just the approved base template.
- Objective claims need documentary evidence held before publication, and comparisons must use material, relevant, verifiable features.
- Qualifications must sit where the claim is encountered and cannot be truncated, obscured or separated from it.
- Automated systems should draw from an approved claim library and send anything outside those bounds to human review.
- If the team cannot reconstruct what a recipient saw, the automation should remain paused.
1. Capture the complete communication
Save the subject line, preview text, creative, generated wording, personalisation, price block, button text and landing page. Include the mobile view and every audience variant. An approval of disconnected components cannot show the overall impression.
Capture every communication element
- Subject line and preview text
- Creative and generated wording
- Personalisation and price block
- Button text and landing page
- Mobile view and audience variants
The Consumer Protection from Unfair Trading Regulations 2008 prohibit misleading commercial practices, and the Digital Markets, Competition and Consumers Act 2024 is set to replace that regime. The CMA's guidance on unfair commercial practices and price transparency explains that an overall presentation may mislead even where individual information is not false. It also covers material omissions and the need to identify commercial intent in relevant consumer dealings.
2. Write down the likely claim
Translate copy into the proposition a reader may understand. "Save hours" might be treated as an objective performance claim, while a comparison may imply superiority beyond the named feature. Record the audience, product, conditions and period covered.
Translate copy into a claim
Copy
- Save hours
- Objective performance claim
- Comparison
- Implied superiority
- Record
- Audience, product, conditions, period
- Decision
- Qualified reviewer, not a model
Likely claim
- Save hours
- Comparison
- Record
- Decision
Do not let a language model decide that a phrase is puffery. The final decision belongs to a qualified reviewer who can consider the wording and context.
3. Match evidence before scheduling
CAP Code rule 3.1 prohibits marketing communications that materially mislead, and rule 3.7 requires marketers to hold documentary evidence before publication for objective claims capable of substantiation. The comparison rules in section 3 (rule 3.33) require identifiable comparisons to rest on material, relevant, verifiable and representative features. The Code is written by the Committee of Advertising Practice and enforced by the Advertising Standards Authority (ASA), whose rulings register is public.
Evidence pack per claim
- Source document and methodology
- Sample and geography
- Dates and limitations
- Named owner
- Matches advertised product and configuration
For each claim, retain the source document, methodology, sample, geography, dates, limitations and owner. Check that the evidence concerns the advertised product and configuration. A supplier's broad product statement is not evidence for a customer's new performance promise.
4. Test qualifications in context
Put a material limitation where the claim is encountered. CAP Code section 3 requires qualifications to be clear and not to contradict the claim. An automation preview should test character limits, image failure, responsive layout and destination changes. Reject any variant in which the necessary qualification is truncated, obscured or separated from its claim.
5. Make advertising recognisable
CAP Code rule 2.1 requires marketing communications to be obviously identifiable as such, and section 2 specifically addresses unsolicited email and advertorials. Review whether the commercial nature is apparent before a person opens or interacts with the communication where the relevant rule requires that result.
Paid, sponsored or affiliate relationships need a disclosure that works in the actual placement. Do not rely on an internal campaign name or a label that only marketing staff understand.
6. Constrain automated changes
Give the system — whether the journey runs on HubSpot, Klaviyo, Braze, Marketo or a smaller tool — an approved claim library rather than permission to improvise. Lock numbers, comparison sets, price conditions and mandatory disclosures. Send changes outside those bounds to human review. Log the input, generated output, editor, evidence version and released text.
Pause the journey if a product fact, evidence period or landing page changes. A previous approval should not travel automatically to new wording.
Sector rules to confirm before release
Immediately before release, confirm the current CAP Code, the CMA guidance and the sector rules that apply to what you sell: financial promotions are governed by the Financial Conduct Authority's rules, gambling advertising by the Gambling Commission's licence conditions and codes of practice, and alcohol and health claims by the CAP Code's own sector sections. Preview each active variant and confirm that its substantiation has not expired.
The final record should show the exact communication, evidence pack, reviewer, decision, conditions and timestamp. If the team cannot reconstruct what a recipient saw, the automation should remain paused.
Before you act
- Save every variant, inserted field and landing page before release.
- Write down the likely claim and the audience it targets.
- Match evidence to each claim before scheduling the send.
- Test qualifications in context, including mobile and image failure.
- Make the commercial nature clear in the actual placement.
- Lock numbers, comparisons and disclosures to an approved library.
Common questions
What should be captured before an automated send goes live?
Save the subject line, preview text, creative, generated wording, personalisation, price block, button text and landing page. Include the mobile view and every audience variant. An approval of disconnected components cannot show the overall impression a consumer is likely to take.
When must documentary evidence be held for an objective claim?
CAP Code rule 3.7 requires marketers to hold documentary evidence before publication for objective claims capable of substantiation. For each claim, retain the source document, methodology, sample, geography, dates, limitations and owner. Check the evidence concerns the advertised product and configuration, not a supplier's broad statement.
What should happen if a product fact or landing page changes?
Pause the journey if a product fact, evidence period or landing page changes. A previous approval should not travel automatically to new wording. The final record should show the exact communication, evidence pack, reviewer, decision, conditions and timestamp, so the team can reconstruct what a recipient saw.
