MX Lookup API + Gmail Integration

Why connect them

The MX Lookup API in Gmail.

Gmail is the world's most popular email service. Integrating APIs with Gmail enables automated email processing, intelligent responses, and data extraction from messages. Transform your inbox into an automated workflow engine.

What you can build

Workflows worth wiring.

Extract and validate email addresses from incoming messages

Automatically categorize emails based on content analysis APIs

Generate response drafts using data from external APIs

Process attachments through document analysis APIs

Templates

Ready-made ideas.

New email received Look up MX records → label message

Look up sender MX records on incoming mail

Look up MX records for the sender's domain on incoming Gmail messages. Auto-label emails based on the primary mx exchange hostname.

New draft created Look up MX records → warn if no records

Check recipient domain before sending

Before sending outreach emails, look up MX records for the recipient's domain. Get a warning if the mx array is empty.

Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Gmail as the trigger app and "New email" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the MX Lookup API, and map your trigger data to the request.
3
Send it back. Add a second Gmail action for "Send email" and map the returned fields (like domain) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a Gmail module set to "New email". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/mxlookup with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a Gmail module for "Send email". Map fields like data.domain into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a Gmail trigger node for "New email" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/mxlookup using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Gmail node for "Send email" and reference the response with expressions such as {{ $json.data.domain }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.
