Mailgun Email Sender

Send a plain-text email through Mailgun and return the message ID and complete queue acceptance result.

Setup

Select your Mailgun account in Send Mailgun email and allow mailgun.send_email. Configure its API key and US or EU API base URL to match the sending domain’s region. Run with Domain, From, To, Subject and Text. To is an array of recipient addresses or Mailgun-supported friendly-name addresses. Use a verified sending domain; sandbox domains can send only to authorized recipients.

In n8n, select Mailgun credentials, set the API region and sending domain in those credentials, and replace the sender, recipients, subject and text in Mailgun. Separate multiple recipients with commas.

Each run makes one send request with the configured recipients and plain text. It adds no attachment, template, CC or BCC. The result preserves the API’s message ID and other returned fields. Queue acceptance does not confirm inbox delivery. Sending can consume your Mailgun plan allowance.

This template sends real email and leaves tracking and delivery settings at Mailgun’s account defaults. No duplicate check or automatic retry is configured. A rejected request, missing message ID or request failure stops the run; check Mailgun before repeating an uncertain send.

Changes to the source

• Replace example email content and account details with user configuration.
• Check the queued message ID in both formats and expose the full result in Open Flow.

Adapted from Mailgun email send workflow in Zie619/n8n-workflows. The source export does not identify a separate template author or license.

The collection’s MIT notice is pinned at a later revision. This is the collection notice at that revision; it does not establish a separate original template author’s license. Our changes are listed above; see repository licensing.
