Meta-data retention

Email metadata is information like sender, recipient, subject, timestamps, and routing details that help deliver, organize, and authenticate email messages.

Within Account Settings meta-data retention can be configured from 1 up to 30 days.

Message-data retention

Message data is the full email data. Including the meta-data, body text, images, attachments, and formatting that the recipient sees and interacts with.

Within Account Settings message-data retention can be configured from 0 to 30 days.

Override retention for individual emails

You can override the account wide retention settings by adding a header to your emails.

• Set the seseu-metadata-retention header between 1-30 to specify a custom meta-data retention period.
• Set the seseu-data-retention header between 0-30 to specify a custom data retention period. 0 disables data retention for the email.

The header will be removed before the email is delivered.

Object Store retention

Object-store retention refers to storing a copy of message data in an external storage system even after it is removed from our system.

When message-data retention is set to 0 days, the content is deleted from the platform immediately after processing. However, if object-store retention is enabled, a copy of the message data is stored in the configured external object store, based on the customer's own storage policies.

This allows customers to retain full control over long-term storage, backups, and compliance outside the email platform.

Some examples for European Object Store providers: Cyso Object Store, OVHcloud Object Storage, Wasabi Cloud Storage, Hetzner Storage Box, Scaleway Object Storage or you could self-host an Object Store with MinIO.

Enabling Object Store retention

Within Account Settings enable Retain messages on S3. You'll need to configure Endpoint, Bucket name, Access Key and Secret Key.
