What you can automate with Mailgun
Mailgun is a transactional email API built for developers and businesses that need reliable, high-volume email delivery. Unlike marketing email platforms, Mailgun focuses on sending emails triggered by application events: password resets, order confirmations, invoice delivery, and automated notifications. The Mailgun node lets your automation workflows send, receive, and track emails programmatically through the Mailgun API. Businesses use Mailgun in their automations to send personalised transactional emails at scale, process incoming emails as workflow triggers, track delivery and engagement metrics, and manage suppression lists. It is a popular choice for SaaS companies, e-commerce platforms, and any organisation that needs to send emails from automated systems rather than manually from a marketing tool. Osher integrates Mailgun into automated data processing workflows where email is a key communication channel. We build systems that generate and send emails based on real business events, whether that is a completed form submission, a status change in your CRM, or an AI-processed document that needs to be delivered. Every email is tracked, and bounce and complaint data feeds back into your systems to keep your sender reputation healthy.

Common questions about how Mailgun consultants can help with integration and implementation
How it works
Implementing Mailgun
Step 1
Set Up Your Mailgun Domain
Add and verify your sending domain in Mailgun. Configure SPF, DKIM, and DMARC DNS records to authenticate your domain. This step is critical for email deliverability and avoiding spam filters.
Step 2
Generate Your API Key
Create an API key in your Mailgun dashboard. You can use a domain-specific sending key for better security, which limits the key to sending emails from a single domain rather than granting full account access.
Step 3
Add the Mailgun Node to Your Workflow
Insert the Mailgun node into your automation workflow and enter your API key and sending domain. Select the operation: send an email, retrieve message events, manage mailing lists, or validate an email address.
Step 4
Compose the Email
Set the recipient, subject line, and email body. Use data from previous workflow nodes to personalise the content. Choose between plain text, HTML, or a Mailgun template. Add attachments if needed.
Step 5
Configure Tracking and Tags
Enable open and click tracking if you need engagement data. Add custom tags to categorise emails for reporting. Set up webhook endpoints to receive delivery notifications, bounce alerts, and complaint events.
Step 6
Send a Test Email and Verify Delivery
Run your workflow and send a test email to verify it arrives in the inbox (not spam). Check the Mailgun logs to confirm delivery status. Review the email rendering across different email clients if you are using HTML templates.
