Subprocessors

Effective date: July 1, 2026

This page lists the subprocessors that SimpleNewsletter365 uses to process personal data on behalf of customers, as referenced in our Data Processing Addendum. We keep this list current and provide notice of changes.

Subprocessors we use

Subprocessor	Purpose	Data processed	Location
Microsoft Azure (Azure SQL, Azure Blob Storage, Azure Key Vault)	Application hosting, database, image asset storage, and encryption key management	All account and audience data, encrypted token key rings, image assets	West Europe (Netherlands)
Microsoft Graph and Microsoft Entra	Authentication and sending newsletters through the customer’s own Microsoft 365 mailbox	Sign-in identity, mailbox grant metadata, outbound newsletter content and recipients in transit	Microsoft global
Paddle	Subscription billing and payment processing as merchant of record	Account holder billing identity, plan, and transaction metadata	Global (United Kingdom and United States)

Important note on the sending path

SimpleNewsletter365 does not operate a shared email-sending service. Your newsletters are sent from your own Microsoft 365 mailbox through Microsoft Graph. Microsoft, as the operator of your tenant, processes the message and recipient data in the normal course of delivering your mail, under your agreement with Microsoft.

Changes

We will update this page and, where required, notify customers before adding a new subprocessor that processes their personal data. To receive change notifications, contact hello@simplenewsletter365.com.
