Email marketing cost in Luxembourg (2026)

Platform fees on top (list-size based):

Setup fees (one-off):

• List import, segmentation schema, domain authentication (SPF, DKIM, DMARC): €600–€1 400
• Template design (master + 2 variants): €900–€2 200
• Welcome flow setup (4–6 emails with branching): €1 200–€2 400
• Lifecycle flow library (7+ flows): €3 500–€6 500
• GDPR-LU audit, consent record design, privacy notice: €400–€900

Per-campaign add-ons:

• Additional campaign (beyond package) — €280–€450/each
• Landing page to match — €380–€900
• Translation FR → DE or FR → EN — €140–€260/language/campaign
• Translation to LB — €160–€300/campaign (scarcity premium)
• A/B test setup + analysis — €200–€400/test

A 6-month engagement with an agency typically negotiates a 10 % discount on the monthly retainer vs. month-to-month.

LU email marketing sits under the CNPD (Commission nationale pour la protection des données), applying the GDPR and the LU Data Protection Law of 1 August 2018. Non-compliance risks are real: CNPD fines up to 20 M € or 4 % of global turnover, and publicised decisions that harm brand trust.

Opt-in requirements (LU reading of GDPR Article 7):

• Explicit consent — unchecked checkbox, active action from user. Legitimate interest is narrower in LU than in BE or DE for B2C marketing; avoid relying on it.
• Granular consent — separate consents for newsletter vs. transactional updates vs. third-party sharing.
• Record of consent — date, time, IP, form source, consent text version — stored for the duration of processing plus 3 years.
• Easy withdrawal — one-click unsubscribe at the footer of every email; withdrawal processed within 24 h.

Soft opt-in for existing customers: Article 7 LU LTVA permits marketing emails to existing customers for similar products, provided the customer was informed at the point of purchase and given a clear way to opt out. This is the narrow B2B exception; use it carefully.

Data transfer to third countries: Most popular platforms (Mailchimp, Klaviyo, HubSpot) are US-operated. Post-Schrems II, the CNPD requires:

• Standard Contractual Clauses (SCC) between your LU company and the US processor
• Transfer impact assessment (TIA) documenting residual risks
• Supplementary measures (encryption at rest, data minimisation, split-tenant if available)

EU-based alternatives (Brevo headquartered in Paris, ConvertKit, MailerLite) simplify this. Moving from Mailchimp to Brevo to eliminate the US-transfer question is a common LU compliance decision — factor 2–4 weeks of migration work at €1 500–€3 000.

Privacy notice and consent wording: Every signup form must link to a privacy notice in the signup user's language that specifies:

• Controller identity (LU company legal name, Autorisation d'établissement, contact)
• Lawful basis (consent)
• Purposes (marketing, analytics, personalisation)
• Recipients (platform name, any third parties)
• Retention period (typically 3 years of inactivity)
• Rights (access, rectification, erasure, portability, objection)
• Data protection officer contact if applicable
• CNPD complaint right

Auditable evidence: Keep an "email marketing evidence pack" with: consent records sample (5 per quarter); privacy notice version history; platform DPAs signed; technical records of SPF/DKIM/DMARC setup; list hygiene policy; unsubscribe processing log. CNPD audits request this pack within 15 working days.

Failure modes that get LU operators in trouble:

• Pre-ticked consent boxes
• Bought or rented lists ("acheté une base qualifiée")
• Scraping LinkedIn and mailing without explicit consent
• Using a test environment with production data
• Missing SPF/DKIM/DMARC, causing blacklisting and reactive "warming up" via more aggressive content

A €2 000–€2 500/month "full programme" retainer can mean very different things. A precise scope prevents later disputes.

Agency deliverables to expect:

• Monthly strategy review — a one-hour call reviewing the previous month's campaign metrics (open rate, click rate, conversion rate, revenue per email), proposed A/B tests and the upcoming month's calendar.
• Four campaigns built and sent — strategy, copy (in brief language), design in the brand template, audience selection, QA and send. Each campaign includes a plain-text fallback for clients whose email clients block HTML.
• Welcome flow maintenance — monthly review of welcome flow metrics, one optimisation swap or A/B test per quarter.
• Segmentation maintenance — list pruning (inactive, bounced, unsubscribed), segment health checks, re-segmentation when campaign response data suggests it.
• Deliverability monitoring — SPF/DKIM/DMARC status checks, sender reputation tracking (Return Path, Google Postmaster Tools), response to any blacklist events.
• Platform administration — user access, list structure, template versioning, integration health (CRM sync, web form sync).
• Monthly report — a 4–6-page deck with key metrics, insights and recommendations for the next month.

What is usually NOT included in a full programme retainer:

• Original landing page design — priced separately at €380–€900
• Copy translation beyond 1 extra language — €140–€260/language/campaign
• Photography, stock imagery licenses — pass-through
• Custom illustration or animation — €200–€600/asset
• Events, webinars or ad-hoc campaigns above the 4/month cap — €280–€450/each
• Integration engineering beyond native connectors — developer hours at €90–€140/h

Scope creep traps: The two most common scope-creep traps in LU agency retainers are: unlimited "minor edits" that compound into 3–5 hours/month, and "urgent" one-off campaigns that displace planned strategy work. A good retainer has a soft cap on revision rounds (typically 2 per campaign) and a clear trigger for out-of-scope billing.

Measurable outcomes to request monthly:

• Open rate by segment
• Click-to-open rate
• Conversion rate to defined goal (sign-up, purchase, form fill)
• Revenue per email (for e-commerce)
• Unsubscribe rate and its trend
• Bounce rate, soft vs. hard
• Complaint rate (must stay below 0.1 %)
• Growth of the mailable list

List-list ratio red flag: A declining list growth - unsubscribe = net ratio over 3 consecutive months means the programme is extracting value faster than it is building trust. Pause cadence, audit content, re-consent the opt-ins.

TVA standard 17 % applies to email marketing agency fees in Luxembourg. There is no reduced rate on marketing services.

Agency fees — rate comparison on a €2 200 net monthly retainer:

Platform fee TVA:

• EU-based platforms (Brevo/Sendinblue FR, Salesmanago PL, MailerLite LT): typically invoice with the platform's home-country VAT or with LU reverse-charge for B2B. Brevo for a LU company with a valid VAT number usually invoices without VAT, and the LU company accounts for 17 % reverse-charge.
• US-based platforms (Mailchimp, Klaviyo, HubSpot, ActiveCampaign): apply the B2B reverse-charge for EU customers with a valid VAT number; the LU company self-accounts for 17 % output VAT and reclaims 17 % input VAT in the same period — a wash for fully taxable LU businesses.

For partially exempt LU businesses (small insurers, boutique banks, education providers), the recoverable VAT on US-invoiced platform fees is capped at the general deduction rate, typically 60–85 %. This creates a 2–7 % real cost add-on compared to fully taxable peers.

Agency vs. in-house cost comparison:

For a list under 25 000 active contacts, agency retainer is typically the efficient model; above 50 000 active contacts with multiple product lines, in-house + agency support becomes competitive.

Procurement checklist for LU companies:

• VAT number of the agency (LU123...) and location of establishment
• DPA signed under GDPR Article 28
• SCC if any platform or sub-processor is outside the EEA
• Insurance: professional liability cover (€500k+) for brand or campaign errors
• Non-compete and confidentiality per engagement letter
• Deliverables schedule attached to contract
• Out-of-scope hourly rate fixed in advance
• Termination notice (30 days standard LU)
• Data portability on exit: full export of list, flows, templates, reports

Cross-border sellers based in LU: When selling into DE, FR, BE via email, apply the destination-country rules for marketing consent (France's more restrictive B2B rules under LCEN; Germany's UWG stricter double opt-in requirements). A LU-seated email programme targeting DE residents must meet DE double opt-in standards. Expect an EU-compliance layer of €1 500–€3 500/year on agency fees to maintain this.

Email marketing proposals can be non-comparable on purpose — agencies present different package breakdowns that make head-to-head comparison difficult. A standardised brief forces comparable quotes.

The six checks:

• Deliverables quantified. Number of campaigns, flows, reviews, languages — all in hard numbers, not adjectives like "ongoing support".
• Out-of-scope rate disclosed. Hourly rate for out-of-scope work and the trigger for billing it.
• Platform ownership. Who owns the account? A best-practice arrangement: your LU company owns the platform account; the agency has delegated access. Never let the agency keep sole ownership.
• Reporting format. Standard monthly report sample with previous client anonymised.
• Deliverability setup. SPF, DKIM, DMARC configuration responsibility and whether IP warming is included at programme start.
• Exit provisions. Data export format on exit; handover time; whether flow logic is documented for your internal team.

Standardised briefing pack:

• Your current list size, growth rate and churn
• Your current platform (if any) with access details or migration request
• Target audience — 2–3 personas with language preference
• Offer landscape — what you are selling, primary offers, seasonality
• Current metrics baseline — open rate, click rate, conversion (if available)
• Stated goals with numbers (e.g., +25 % email-attributed revenue in 6 months)
• Compliance context — existing privacy notice, DPO if applicable, CNPD interaction history
• Budget ceiling monthly and one-off
• Required languages and markets
• Integration requirements (CRM, e-commerce, analytics)

Typical three-quote spread on an identical brief:

The spread is driven by programme depth and language count, not by hourly rates. Compare year-1 total, not monthly.

Pilot option: For risk reduction, request a 3-month pilot at 80 % of full scope with a month-to-month termination clause in the first quarter. This gives you the chance to evaluate reporting quality, copy quality, and responsiveness before committing to a 12-month programme. Standard LU agency terms accept this.

The decisive question: Ask each agency for a current client reference with similar list size, industry and language mix. A 20-minute call with that reference reveals: average response time, scope creep handling, reporting depth, and rapport on dispute. This single call is worth more than the proposal document.
