Scope verdict

Ownership reviewed, controller unresolved

The legal notice names seven communications GmbH & Co. KG, its general partner seven administration GmbH and managing director Christian Leo. Founder and director roles do not prove current share ownership. The official register indexes a shareholder document for the general partner, but its download failed during this review; ultimate control remains unresolved.

How we classify services

seven offers APIs and a web interface for sending and receiving SMS, delivery reports, phone-number lookups and voice services. WhatsApp Business and RCS are additional channels. The operator is seven communications GmbH & Co. KG in Kiel, Germany.

The approved subcontractor schedule identifies Hetzner hosting in Germany. That supports the core EU-hosting label, but does not mean that messages sent to overseas recipients or through WhatsApp and RCS remain in the EU. Founder and management information is public; ultimate ownership remains unverified.

Pricing

Usage-based, destination-specific SMS pricing. The published table lists €0.075 for Germany, with different rates for some other countries. Longer or Unicode messages may use multiple billable segments. Trial credit is not a recurring free plan; numbers and other services cost extra.

Infrastructure and email path

Verified operational dependencies, shown separately from ownership and from the service's core data hosting.

Core service hosting

Hetzner

European provider

Location: Germany
Observed: Hosting in seven’s approved subcontractor schedule. This is a hosting location, not a promise that international message delivery remains in Germany.
Evidence: seven approved subcontractors: Hetzner, Google RCS and WhatsApp ↗

Message delivery channel

Google / RCS Business Messaging

Non-European provider

Location: EU / USA
Observed: Optional RCS channel in the subcontractor schedule. Separate from the Hetzner-hosted SMS platform.
Evidence: seven approved subcontractors: Hetzner, Google RCS and WhatsApp ↗

Why this matters

The service documents Google / RCS Business Messaging for message delivery. When this channel is used, message content and recipient details can pass through this non-European provider. The cited source describes the channel and any location limits.

Message delivery channel

Meta / WhatsApp Ireland

Non-European provider

Location: EU / USA
Observed: Optional WhatsApp Business channel in the subcontractor schedule; message delivery can use infrastructure outside the EU.
Evidence: seven approved subcontractors: Hetzner, Google RCS and WhatsApp ↗

Why this matters

The service documents Meta / WhatsApp Ireland for message delivery. When this channel is used, message content and recipient details can pass through this non-European provider. The cited source describes the channel and any location limits.

Mail-signing setup

Google Workspace

Non-European provider

TXT google._domainkey DKIM key published

A provider-specific DKIM record is published for Google Workspace. This shows configured mail-signing infrastructure, but not that every message currently uses it.

Current DNS record ↗Provider setup guide ↗

This is a targeted check, not a complete zone inventory. Generic Google and Microsoft verification tokens are ignored because they do not prove product use or a data flow. DNS normally cannot list arbitrary subdomains or customer-chosen DKIM selectors, including Salesforce selectors. Missing signals are not proof that a provider is unused.

DNS checked: 2026-10-18 17:37 UTC

Public DNS records identify visible providers and routes, not every backend location or private data-region setting.
