How it works
DemoPost only receives messages. You keep the sending providers you already use.
- 1
Use your test contact details
Swap the recipient in your test setup for a DemoPost email address or phone number. Your own sending provider stays exactly as it is.
- 2
Run your demo or test
Trigger the flow you want to show: an order confirmation, a verification code, a reminder or a document.

See what arrives
DemoPost receives the real message within seconds, so you can read it, open attachments and show the full journey.
Features
Email and SMS together
One inbox for both channels, so a complete customer journey stays in a single view.
Live message updates
New messages appear as they arrive, with a manual refresh whenever you want to be certain.
Email references
Plus addressing lets you tag every test, like demo+DOS001@in.demopost.net, without extra setup.
Attachment previews
Preview PDFs and images in the browser and download them to check the real document.
Search and filters
Find messages by sender, recipient, subject or content, and filter per channel.
Deletion and cleanup
Delete a message whenever you like; everything else is removed automatically after 30 days.
Use cases
Software demos
Show prospects the emails and text messages their customers would receive, live in the demo instead of on a slide.
Agency handovers
Walk a client through every notification a flow triggers before go-live, with the real content and attachments.
Product testing
Check templates, links, codes and documents across releases with per-test references.
Inside the inbox
A message list and a detail view side by side, with attachment previews. The data shown here is sample data.
