How S3 Compatible (pull) to SES Email routing works
Source
S3 Compatible
DocEvent checks your S3 or S3-compatible bucket on a schedule and collects new files — Cloudflare R2, MinIO, Backblaze B2, Wasabi and more.

Email via SES
Files are delivered as email attachments via Amazon Simple Email Service.
1
File arrives via S3 Compatible (pull)
Scheduled polling of any bucket that speaks the S3 API — Amazon S3, Cloudflare R2, MinIO, Backblaze B2, Wasabi, Supabase Storage and friends (custom endpoint URL and path-style addressing supported). Collects from a prefix with filename pattern filtering, then each collected file is deleted or moved to an archive prefix. No bucket notifications or event plumbing needed.
2
Channel routes it
DocEvent's channel server matches the incoming file to your configured route, queues it for delivery, and ensures no file is ever lost — even during downstream outages.
3
Delivered to SES Email
Amazon SES with configurable sender, recipient, subject, and body. Attachment included.
Common use cases
Real workflows that teams automate with a S3 Compatible (pull) → SES Email channel.
- Email reports to the team as soon as they land in the bucket
- Forward partner files from an R2, B2 or Wasabi drop bucket to a shared mailbox
- Turn a bucket prefix into an email distribution point
- Notify recipients with the actual file attached, not just an alert
The two ends don't have to be the same company — invite a customer or trading partner into the channel and they run the S3 Compatible (pull) or SES Email side under their own account, with their own credentials. Learn how shared channels work.
