EBM reads the undeliverable reports in your Microsoft 365 mailboxes, finds the real failed address, builds a live suppression list, and lets any sending system check it through a secure API.
Undeliverable reports land in mailboxes nobody monitors. Here is what ignoring them costs you, and what EBM does instead.
bnc = bounce reports landing in a mailbox. Read late, copied by hand, or never. The same dead address keeps getting email.
Reports are scanned automatically. Each bad address is stored once, and your sending systems ask before they send.
Undeliverable reports land in an inbox, a junk folder or deleted items, and nobody has time to read them.
EBM scans your Microsoft 365 mailboxes, including Inbox, Junk Email and Deleted Items, without anyone logging in.
The bounce goes to a mailbox, and the failed address is buried somewhere in the body.
EBM extracts the actual failed recipient, not just the mailbox that received the report, and keeps a short reason.
Without a list, every send tries the same dead address and bounces again.
Each failed address is stored once, with first seen, last seen and a bounce count, and re-scans never inflate the numbers.
Bounces mount quietly. By the time you notice, important email is landing in spam.
Sending systems check the list before sending, so known-bad addresses are skipped and bounce rates stay under control.
Technical error text means nothing to the person who has to act on it.
Reasons are shortened to clear labels like user unknown, mailbox unavailable, blocked, quota full, too large and spam.
Someone exports, filters and pastes bad addresses into spreadsheets every week.
Download the bounce log or the suppression list as CSV or Excel, whenever you need it.
The system that sends email has no idea what the mailbox knows.
Any system that can make an HTTP call can check one address or many and get blocked or allowed, with bounce count and last seen.
Bounces arrive in several mailboxes, sometimes across several Microsoft 365 tenants.
Monitor as many mailboxes as you need, grouped by tenant, each with its own status and last sync.
Pick a step to see what EBM does at that moment. Illustrative demo data.
9:00 campaign sent to a long list to [email protected] 550 5.1.1 user unknown an undeliverable report is on its way back
scan Billing mailbox folders Inbox · Junk Email · Deleted Items ✓ undeliverable report recognised ✓ not seen before recommended sync: every 5 minutes
recipients of the report system addresses ignored body of the report checked when needed failed address [email protected] reason user unknown
suppression list address [email protected] reason user unknown bounces 1 (rises on repeat, never double counted) first seen just now ✓ added
GET /[email protected] blocked reason: user unknown bounces 1 the sending system skips the address if EBM is unreachable, the check allows and logs it
Bounces can land in several mailboxes, even across several Microsoft 365 tenants. Each one is scanned, tracked and shown in one dashboard. Demo mailboxes shown.
Suppression applies to the exact address that failed. It does not block whole domains.
Each report is tracked, so re-scanning never inflates bounce counts.
EBM reads the mailbox without storing mailbox passwords.
EBM recognises undeliverable reports, finds the address that actually failed, and keeps just what you need.

| Secure mailbox access | No mailbox passwords. | EBM uses app-only access to your Microsoft 365 tenant, with a built-in connection test during setup and per mailbox. |
| Unlimited mailboxes | Watch every bounce mailbox. | Add, edit, pause, resume and delete mailboxes, each with last sync and last error. |
| Multiple tenants | More than one Microsoft 365 tenant. | Each tenant has its own credentials. Mailboxes are grouped by tenant, and tenants can be paused or set as default. |
| Automatic scanning | Hands-off sync. | Scans Inbox, Junk Email and Deleted Items by default, with configurable folders, and an unattended sync recommended every five minutes. |
| Report recognition | Understands the common notices. | Recognises undeliverable, delivery failure, returned mail, non-delivery and failure notices, including common Microsoft phrasing. |
| Failed address extraction | The right address, not the wrong mailbox. | Takes the failed recipient from the message, or from the body when needed, and filters out system addresses. |
| Plain-language reasons | Know why it bounced. | User unknown, mailbox missing, mailbox unavailable, blocked, quota full, too large, spam, hard bounce and soft bounce. |
| Automatic list | One row per failed address. | First seen, last seen and bounce count, deduplicated so repeat scans do not inflate counts. |
| Manual control | Add or remove when you must. | Admins can add or remove addresses, reset counts and clear the list. |
| Exports | CSV and Excel. | Export the bounce log or the suppression list as CSV or Excel-compatible files. |
| Real-time check | Blocked or allowed. | Check one or many addresses by GET or POST, with a key in a header, and get bounce count and last seen for blocked ones. |
| Suppression export API | Sync the list elsewhere. | A paginated, searchable export of the full suppression list, secured with the same key. Rotate the key whenever you need. |
| Works with any sender | Any system that can make an HTTP call. | Use it from a CRM, an ERP, a lab system, your own code or a native SMTP configuration. |
| Dashboard | Trends and telemetry. | Suppressions added today, week, month, year and lifetime, a seven-day ingestion trend, hit rate and mailbox distribution. |
| Bounce log | Searchable history. | Every report with the failed recipient, mailbox and folder, and a detail view with reason and full message. |
| Top blocked domains | See where bounces cluster. | Domain roll-ups for reporting, with visual bars. |
| Viewer and admin roles | Read-only or full control. | Viewers see the dashboard, log and list. Admins manage mailboxes, tenants, settings and destructive actions. |
| Activity log | A trail of what happened. | Sign-ins, mailbox and tenant changes, suppression changes, API and sync events with IP and time. |
| Settings and branding | Make it yours. | Application name, tagline, theme, folders, retention, session and login-limit settings. |
| Hosted and managed | Nothing to install. | EBM is a SaaS product that we host, update and maintain. We connect your Microsoft 365 tenant and test the mailboxes with you. |
Email that bounces is not a small problem. If your business depends on email, bounce rates deserve attention before they become a deliverability crisis.

EBM (Email Bounce Monitor) reads non-delivery reports from your Microsoft 365 mailboxes, extracts the real failed addresses, builds a live suppression list, and exposes it through a secure API.
No. EBM works on its own with any system that can make an HTTP call. SMMP is an optional companion: it can sync EBM’s list and skip bad addresses on every send.
No. EBM monitors and builds the suppression list. Your sending system, or SMMP, checks the list before sending.
It scans configured folders in your Microsoft 365 mailboxes, by default Inbox, Junk Email and Deleted Items, recognises undeliverable reports and extracts the failed recipients and reasons.
A scheduled sync is recommended every five minutes, and admins can also refresh on demand.
No. EBM uses app-only access to your Microsoft 365 tenant.
No. Suppression applies to the exact address that failed. Domain data is used for reporting.
They call the check API before sending and skip any address that is blocked, or they pull the full list through the export API. It can be used from any system, even a native SMTP configuration.
If EBM cannot reach its database, the check returns allowed and the incident is logged, so sending is not interrupted. This is a deliberate availability choice.
