Voxia
Sovereign email marketing for teams that own their audience data.
Voxia gives European organizations a controlled workspace for newsletters, announcements, automated journeys, subscriber consent, campaign analytics, and CRM-connected audience operations without pushing customer relationships into a black-box marketing cloud.
01 — Problem
Email marketing becomes risky when audience data lives outside your control.
Newsletters, product announcements, onboarding journeys, and customer nurture campaigns depend on personal data, consent records, engagement history, and sending-domain reputation. When those workflows sit in separate external platforms, teams lose visibility into where data lives, how consent is enforced, and what happens when a subscriber asks for access or erasure.
- Subscriber lists, engagement history, and custom fields are scattered across tools and exports.
- Consent, unsubscribe, suppression, bounce, and complaint handling are difficult to prove consistently.
- Campaign approval, test sending, scheduling, and post-send reporting depend on manual coordination.
- Marketing, CRM, HR, and compliance teams work from different audience records.
- Costs and lock-in rise as contacts, sends, automations, and premium reporting needs grow.
- Regulated organizations struggle to explain jurisdiction, access control, and data lifecycle for marketing data.
02 — Solution
Voxia turns email marketing into a governed Vianordis workflow.
Voxia combines a Next.js campaign workspace, a Go API, Keycloak authentication, tenant-scoped PostgreSQL records, background sending workers, public subscription endpoints, and integration jobs for CRM and employee audiences. Teams can build lists, segment subscribers, design responsive templates, schedule campaigns, run automations, and handle GDPR requests from one controlled environment.
- Communications teams manage contact lists, subscribers, tags, fields, opt-in status, suppressions, and preferences in one workspace.
- Campaign owners create drafts, choose templates, send tests, schedule delivery, and measure opens, clicks, bounces, complaints, and unsubscribes.
- Operators keep identity, tenant context, sending-domain configuration, webhooks, rate limits, and compliance workflows inside the Vianordis operating model.
03 — Benefits
Business outcomes before campaign mechanics.
Voxia is built for teams that need measurable email communication without losing control of consent, audience data, sending infrastructure, or integration boundaries.
Reduce compliance workload
Use built-in unsubscribe handling, preference centers, consent audit records, suppression lists, and GDPR export/delete workflows instead of manual evidence gathering.
Coordinate campaigns faster
Give teams one path for templates, test emails, scheduling, approval status, delivery tracking, and campaign analytics.
Automate repeat communication
Create triggered workflows, autoresponders, drip campaigns, enrollments, and goal tracking for onboarding, nurture, internal updates, and re-engagement.
Connect real business data
Sync audiences from Nodus CRM and Zelibri HR so customer and employee communications can use current lifecycle, department, and consent context.
Avoid platform lock-in
Use standard data exports, API routes, webhooks, MJML/HTML templates, and portable engagement history instead of trapping campaigns inside a closed vendor system.
04 — How it works
From audience to measurable campaign in three steps.
- 01
Build and qualify the audience
Create lists, import subscribers, capture signups through forms, sync contacts from connected systems, and segment recipients by consent, lifecycle, behavior, tags, and fields.
- 02
Design and approve the message
Create responsive MJML or HTML templates, add subject and preheader content, personalize with subscriber data, send tests, and hold the campaign as a draft or approved send.
- 03
Send, automate, and report
Schedule or send campaigns through the worker pipeline, trigger journeys when subscriber events happen, and review delivery, engagement, cohort, and deliverability metrics after launch.
05 — Features
What teams can actually do in Voxia.
Audience and subscriber management
Create lists, import and export subscribers, track pending, confirmed, unsubscribed, bounced, and complained statuses, and maintain tags, custom fields, locale, timezone, and consent metadata.
Campaign builder and scheduling
Create regular, A/B, automated, or transactional campaigns with subject lines, sender details, template selection, recipient counts, approval status, tests, throttling, scheduling, and send controls.
Template system
Manage reusable templates with MJML, HTML, text content, preheaders, version history, reusable blocks, imprint requirements, footer content, previews, and duplication workflows.
Segmentation
Define rule-based segments, preview match counts, refresh segment membership, and target campaigns to audiences that match profile, consent, engagement, or custom-field rules.
Automation journeys
Build workflow, autoresponder, and drip automations with triggers, steps, branching, active enrollments, completion tracking, pause/activate controls, and goal metrics.
Analytics and reporting
Review dashboard metrics, campaign stats, list growth, engagement, deliverability, cohorts, recipient events, click activity, and per-subscriber engagement history.
Signup forms and preference flows
Create embedded, popup, or landing-page forms with double opt-in, confirmation emails, CAPTCHA or honeypot protection, success handling, preference centers, and form analytics.
Sending-domain controls
Register and verify sending domains, inspect SPF, DKIM, DMARC, MX, return-path status, warmup settings, and daily send limits.
Compliance operations
Manage suppression records, consent audit views, one-click unsubscribe handling, GDPR data exports, and subscriber deletion requests from protected admin routes.
06 — Architecture
Architecture and security model.
Voxia separates the user workspace, API policy, background sending, public tracking flows, and integration jobs so each layer can be operated and audited deliberately.
- Next.js provides the localized campaign workspace, list views, analytics surfaces, template editors, journey builders, and AI-assisted UI components.
- A Go Fiber API exposes lists, subscribers, templates, campaigns, segments, automations, forms, domains, analytics, compliance, settings, integrations, and webhook routes.
- Keycloak OIDC validates JWTs locally through cached JWKS keys, tenant context middleware scopes requests, and admin-only routes protect compliance and settings operations.
- PostgreSQL stores contact lists, subscribers, templates, campaigns, recipients, segments, automations, forms, sending domains, suppression records, consent audit, sync logs, and tenant settings.
- Background workers process email sends, campaign queues, bounce and complaint handling, automation triggers, enrollments, and engagement updates.
- Public endpoints handle open tracking, click redirects, unsubscribe, preferences, view-in-browser pages, form submissions, and double opt-in confirmation.
- Webhook signing protects inbound operational events, while CORS validation, helmet headers, request logging, recovery middleware, and per-tenant rate limits harden the API edge.
- A WebMCP service exposes controlled campaign operations to AI agents and assistant-driven workflows.

Can Voxia replace tools like Mailchimp or HubSpot email campaigns?
Voxia covers core email marketing workflows: contact lists, subscribers, templates, campaign scheduling, test sends, automations, forms, tracking, analytics, and compliance operations. A demo should validate migration details, advanced segmentation needs, and any channel-specific requirements.
How does Voxia handle consent and unsubscribes?
Subscriber records include confirmation, consent, lawful-basis, unsubscribe, bounce, complaint, preference, and suppression context. Public unsubscribe and preference endpoints support subscriber self-service, and admin routes support consent audit review.
Does Voxia support automations?
Yes. Voxia supports workflow, autoresponder, and drip automations with triggers, journey steps, enrollment tracking, activation, pause controls, and automation analytics.
What integrations are available?
The app includes CRM sync, Zelibri HR sync, webhooks, REST API routes, public form endpoints, SMTP delivery, Keycloak identity, and WebMCP/MCP interfaces for AI-assisted operations.
Can teams export subscriber data?
Yes. Voxia includes list subscriber export routes and protected compliance workflows for subscriber data export and deletion.
