Our solutions

Each problem above, solved in detail.

Email deliverability

Land in the inbox, not the spam folder

Google, Yahoo and Microsoft reject unauthenticated mail. A quote in spam is a lost quote. We configure SPF, DKIM, DMARC, BIMI and MX so every invoice and follow-up arrives.

Secure my emails

SPF, DKIM & DMARC

All your sending tools are authenticated: Google Workspace, Microsoft 365, CRM, newsletter.

BIMI & MX

Your logo next to your emails, and MX routing cleaned up.

Reputation you can see

Postmaster Tools and DMARC reports: you see your domain’s reputation instead of guessing it.

Server-side tracking

Your conversions, finally visible to your ad tools

Ad blockers and browsers filter part of your events before they reach Meta or Google Ads. Server-side tracking sends them from your subdomain, deduplicated and with consent.

Make my tracking reliable

Server-side GTM

A server container on your subdomain: fewer lost conversions.

Meta Conversions API

Browser and server events deduplicated; a test plan shows what Meta receives.

Consent respected

Linked to your consent tool: only accepted data is sent.

Lead alerts

Every request handled within seconds

A lead left waiting goes elsewhere. Every contact is created in your CRM and your team is alerted on WhatsApp, by email or on Slack.

Answer faster

Straight into your CRM

Every lead lands in your CRM on its own. No more copy and paste.

Instant team alert

The right person is alerted within seconds and calls back while the lead is warm.

Tested end to end

Make or Zapier scenario tested from form to alert, with a guide for your team.

When the audit ends,
the fix begins...

Cookies & consent

Consent first, on every page

A banner on its own proves nothing if your tags fire anyway. We block every non-essential script until your visitors agree.

The law does not ban cookies: it punishes fake banners and the lack of prior consent. The CNIL fines website publishers directly.

What a non-compliant site risks in France

Administrative fine, up toor 4% of worldwide annual turnover€20M
Daily penalty until compliance, up to€100,000

Figures for France; they vary by national authority in the EU.

Public formal notice: the CNIL publishes them, which tarnishes your image.
Google Ads: without compliant Consent Mode v2, remarketing and modelling are limited in Europe.

Sources: GDPR, art. 83 · French Data Protection Act, art. 82 · CNIL · Google Consent Mode

Free check: we list the scripts that fire before consent and tell you whether you need to comply.

Consent that holds up

Axeptio, Cookiebot or Didomi, set to your colours and tested before and after the click. Report sent to your DPO.

Script blocking & Consent Mode v2

Analytics, pixels and chat wait for consent; Consent Mode v2 keeps your numbers usable.

Whatever your website

Shopify, Webflow or WordPress, app and Tag Manager tags included.

European Accessibility Act New

Does your site have blocking anomalies?

Since June 2025, the European Accessibility Act (EAA) has applied to many online stores, with penalties set by each member state. Our diagnostic answers clearly: blocking anomalies, yes or no, which to fix, and in what order.

Penalties provided for in France

Fine, starting from€7,500
Penalty per day if an order is ignored€3,000
Maximum total of the penalty€300,000

Amounts for France; they vary elsewhere in the EU.
