MEET YOUR EMAIL’S NEW SUPERPOWER.

Connect your mailbox to an email API.

MailBridgeAPI links your own SMTP and IMAP mailbox to an account API key and a mailbox API key. Use both keys in HTTP requests to send from, read, and operate that same mailbox across your projects.

SEE THE CONNECTION

One mailbox becomes an API your projects can use.

MailBridgeAPI securely links your SMTP and IMAP mailbox to two API keys. Your applications then call clear endpoints to send email and process received messages without using the mailbox password.

EMAIL IS BUSINESS-CRITICAL.

Integrate your mailbox—and know it is working.

MailBridgeAPI serves two needs at once: developers get a consistent email API for their projects, while companies get a fast way to check the mailboxes their activity depends on.

FOR DEVELOPERS

Build without rebuilding SMTP and IMAP

Use stable HTTP endpoints for sending, receiving, searching and health data in every authorized integration.

FOR COMPANIES

Keep critical mailboxes under control

Check access, test outgoing and incoming connections, and find sending errors before they disrupt customers or operations.

Explore every control endpoint

MAILBOX CONTROL

The essentials, visible in one place.

Use the dashboard, mobile application or API endpoints to verify the service quickly.

Mailbox accessible

Confirm that the configured account can still be reached.

CHECK ACCESS

SMTP operational

Test the outgoing connection used by your applications.

TEST SMTP

IMAP operational

Test access to incoming messages and folders.

TEST IMAP

Sending errors visible

Open the activity log, identify the reason and act quickly.

VIEW ERRORS

Email carries customer requests, confirmations, invoices and alerts. Its availability should never be left to guesswork.

ONE MAILBOX. EVERY PROJECT.

Change the mailbox password once. Keep every project running.

Imagine that the same SMTP mailbox sends email from a website, an invoicing tool, internal automations and dozens more projects. When its password or provider settings change, update the connection once in MailBridgeAPI.

Without MailBridgeAPI

Every project stores the SMTP configuration. A password change becomes a search through every application, followed by new deployments and the risk of forgetting one.

With MailBridgeAPI

Every project calls the same email API. Update the mailbox connection in the dashboard; the applications keep using their existing API integration.

One change instead of one change per project.

Whether the mailbox is used by three projects or hundreds, no source-code or deployment change is needed when only its mailbox password or connection settings change.

YOUR PROJECT NEEDS EMAIL. NOT THE EMAIL PASSWORD.

Integrate the mailbox. Keep its password out of the project.

Your client or mailbox owner connects the email account in MailBridgeAPI. You build the integration with API keys, without needing to know their mailbox password.

See the client integration example

Integrate the mailbox. Keep its password out of the project.

Mailbox owner

Enters SMTP / IMAP credentials in MailBridgeAPI.

MAILBOX CREDENTIALS

MailBridgeAPI

Uses the configured connection to communicate with the mailbox.

API KEYS

Developer & application

Uses account and mailbox API keys to send or retrieve emails.

The developer does not need the mailbox password.

A more reassuring client handoff

The owner enters the mailbox credentials. The developer receives the API access needed for the integration.

Fewer places to share a password

Keep the mailbox password out of project source code, developer messages, and individual application configurations.

One place for connection settings

When mailbox settings change, update the connection in the dashboard instead of redistributing the password across projects.

MailBridgeAPI still needs the owner’s mailbox credentials to connect to the email provider. API keys grant access to email operations: treat them as secrets and keep them in your backend.

THREE STEPS. ENDLESS POSSIBILITIES.

From inbox to integration.

A familiar mailbox on one side. Your next great idea on the other.

Connect your mailbox

Add your SMTP and IMAP settings in the dashboard. Keep using your existing address and email provider.

SMTP + IMAP

Get your API keys

MailBridgeAPI links your account API key and a mailbox API key to the mailbox you selected. Your application never needs the mailbox password.

API KEY + MAILBOX KEY

Make your first request

Call an endpoint with both API keys. The request sends from or reads the same mailbox selected by the mailbox key.

HTTP REQUEST → EMAIL

SMTP + IMAP → HTTP

Keep the mailbox. Simplify the integration.

SMTP and IMAP are how email works. You shouldn’t have to rebuild that connection in every project. MailBridgeAPI gives your applications a consistent API while you manage your mailbox settings in one dashboard.

One mailbox, multiple projects. Update its connection settings in one place.

What you’ll need

A mailbox you are authorized to connect
SMTP host, port, username, and credentials
IMAP host, port, username, and credentials
Provider-approved authentication and access settings

Your mailbox stays yours.

MailBridgeAPI uses your existing email service. It does not replace your email provider or remove its limits. You keep your address and continue using your usual email client.
