Significantly streamline your communication processes with this Mailgun Transactional Email integration.


This integration will allow you to send transactional emails with attachments to any email address.


Automate the sending of crucial, time-sensitive non-marketing emails such as order confirmations, receipts, monthly invoices, shipping notifications, and account updates and alerts directly from HubSpot.


Leverage Mailgun's robust deliverability features and detailed analytics. Businesses can monitor email performance with metrics on open rates, click rates, and delivery success, enabling them to optimise their email strategies effectively.


With the Mailgun Transactional Emails from Integration Glue, you can:

  • Automatically send Transactional Emails with Attachments

  • Select Mailgun Templates from the Workflow

  • Overwrite Mailgun templates with your own HTML directly from Workflows

  • Personalise emails with Tokens

  • Capture Mailgun emails as Email activities against the record timeline

  • Any Object (Contacts, Companies, Deals, Tickets, Custom Objects)

  • Any errors or issues are logged against the HubSpot Workflow

  • Fully managed within HubSpot Workflows - once installed you do not need to login to any other system to manage your actions.

When you register for Integration Glue, you will get access to a whole bunch of HubSpot Workflow and Data productivity actions, such as Actions to Clone records (including associated records), get User/Owner information and add to a Property or calculate a date.

Integration Glue pricing is based on utilization, so you can use all of our apps together under a single license and you will only be charged for the total credits you use per month.

Integration Glue does not retain any data or files when using this app; it simply reads and outputs data to your own HubSpot portal.


Send Transactional Emails from Workflows

Send transactional emails from Workflows by integrating with Mailgun. Utilize data from enrolled and associated records to customize email details (subject, email body, from name, from address, primary recipients, BCC recipients). Select a Mailgun region and domain to streamline your email delivery process.

Attach files to Transactional emails

Attach files to transactional emails with this app that extends HubSpot's capabilities. HubSpot's native functionality lacks support for sending automated transactional or marketing emails with attachments. This feature allows you to automate the sending of important documents such as invoices, contracts, or detailed reports.

Use Mailgun Templates or Overwrite template content

Use Mailgun Templates or overwrite template content directly from HubSpot Workflows. Select templates from your Mailgun account and add code to replace template data with information from enrolled and associated records. This feature allows rich, personalized transactional email content and designs.

Log emails sent against the CRM record timeline

Log emails sent as an email Engagement against CRM record timelines. Associate the Mailgun email with the enrolled record or other associated object records. Or utilize data from enrolled and associated records to specify record IDs for email association, ensuring comprehensive email tracking and visibility.
