Two free checks per day per IP address

SMTP

Test your SMTP mailbox

2/2 today

Your SMTP password is used only to send this test and is not stored. Mail-tester processes the synthetic message and delivery headers; the report is saved in MailBridgeAPI.

Your report will appear here after the check.

A score helps find common issues but cannot guarantee inbox placement. Email providers apply their own filters.

YOUR OWN MAILBOX. YOUR API KEYS. YOUR REQUESTS.

Connect your own mailbox to API keys, then control it through endpoints.

MailBridgeAPI links the SMTP and IMAP mailbox you own or are authorized to use to an account API key and a mailbox API key. Every request selects that same mailbox: send from its address, read its received messages, or process them in your applications.

POST /sendemail/

Send through your mailbox

A POST request uses the SMTP connection of the mailbox selected by apikeybox and sends from that mailbox.

GET /getemail/

Read your mailbox

A GET request uses the same mailbox key to retrieve messages from its configured IMAP folders.

YOUR LOGIC. YOUR WORKFLOW.

Use your mailbox data

Your authorized application handles the result in its workflows, automations, CRM, support tools, or AI systems.

Connect only a mailbox you own or are authorized to use. The provider must allow compatible SMTP or IMAP access, and its limits still apply.
