⚡ Mailgun n8n Automation Workflows

Browse ready-to-use n8n workflows that connect Mailgun with your stack—send transactional email, route replies, log events, and alert your team when messages fail or bounce.

These Mailgun workflows are for teams who send important email and can’t afford missed bounces, silent failures, or manual follow-ups. If you’re in support, sales ops, product, or growth, you’ll save time by auto-sending messages, capturing webhook events, and syncing outcomes to the tools you already use. Reduce busywork, respond faster, and keep deliverability issues visible before customers complain, honestly.

📊 About Mailgun

Mailgun is an email delivery platform used to send and track transactional and bulk email through APIs and SMTP. It helps you manage domains, templates, and suppression lists, and it provides webhooks for events like delivered, opened, clicked, bounced, and complained. For automation, that means you can trigger workflows from real email activity, route failures to the right team, and keep your customer records and dashboards accurate without manual exports or inbox digging.

How do I connect Mailgun to n8n?

In n8n, add a Mailgun node and create credentials using your Mailgun API key. If your workflow is event-driven, set up a Mailgun webhook that points to an n8n Webhook trigger URL, then test with a real email event (like a bounce). Make sure your Mailgun domain is verified and the webhook is enabled for the events you care about. Once you see a sample payload in n8n, map fields and add actions like Slack alerts or CRM updates.

What can I automate with Mailgun?

A lot: sending transactional emails, handling bounces/complaints, routing inbound replies, and logging delivery events to a sheet or database.

Do I need a Mailgun account?

Yes. You will need an active Mailgun account (and a sending domain set up) to use these workflows end to end. Some templates can be explored with sample data in n8n, but real sends and real event tracking require your Mailgun API key or SMTP credentials. If you’re just starting, set up one domain, verify DNS, then run a simple “send + log result” workflow first. It’s the quickest way to confirm everything’s wired correctly.

What are common Mailgun automation use cases or limitations?

Common wins include: alerting Slack when a message bounces, updating HubSpot when an email is delivered, and writing event streams to Google Sheets for daily reporting. Limitations are usually about deliverability and data, not n8n. If your domain isn’t authenticated (SPF/DKIM), automation won’t fix inbox placement. Also, opens/clicks depend on tracking settings and user privacy features, so treat them as directional signals. Webhook payloads can be noisy; filter early to keep workflows clean.
