The Business Component Send e-mail is designed to allow you to configure your Message Events to send an automatic e-mail message when running a process application and is available to you in the Barium BPMN Modeler tab called Business Components.

For example, the Send e-mail Business Component can be used to tell somebody that your process has progressed to a certain phase, to send an automatic response that a registered case has been received, to inform an interested party that the process has passed a milestone or to inform one or more interested parties that the process has ended.

The Send e-mail Business Bomponent has the capability of sending e-mails to a specified e-mail address, to the participant set in the process model, or to an e-mail address that has been filled out in a form field by the person who registered the case in the first hand.

Additionally it’s possible to add variables in the e-mail text which can get information from the process instance or out of form fields and present it in the e-mail text. For example: In a process you may have an form with a field for the “reviewers comments” allowing the reviewer to document the outcome of a review. The text filled out in the “reviewers comments” field can be inserted into the e-mail text through a variable and sent to whoever you choose to be the recipient.

Adding the Send e-mail Business Component

The Send e-mail component can only be added to BPMN symbols that send messages such as:

  • Intermediate Event configured with an Intermediate Trigger
  • End Event configured with an End Result Type
  • Tasks configured to be a Send Message Task Type

To configure your process model to add the Send E-mail Business Component simply drag it from your Business Components palette and drop it on the flow object where you wish to send an automatic e-mail.

A window will open where you add the parameters of the business component and configure you’re the e-mail message to send.

Send e-mail Business Component parameters


The subject text in your e-mail message.


The body text in your e-mail message.


The ID of the field in your form from which you want to fetch the e-mail addresses to send this message to. Requires that your process model contains an form and a specified field for e-mail addresses.

You must fill out the ID of your form as well as the name of the field in the form with a dot in between for this to work: MyEform.Email. Note that the ID of your form and the name of your email form field is up to you to define.

The ID of the form can be found in the process models Data objects tab. The name of your form field can be found when creating or editing the form in the form editor. In the Picking up form data: DataID & FieldName article you find a short guide how to find and change DataIDs and field names.


A field where you can write one or more e-mail addresses to send the message to. These are static e-mail addresses and will send a message to the same e-mail addresses every time your process reaches the business component. This is an effective way of informing external interested parties when a process instance has been received or passed through a specific path in your process.

To add several e-mail addresses, simply write a comma between each address and the message will be sent to all recipients.


A checkbox which you can check in order to send the e-mail to the registered e-mail address(es) of the participant set on the configured task or event , or on the lane which it is placed in.


Use this setting to send the e-mail to the registered e-mail addresses of all the previous performers in all roles of the instance. 


This setting sends the e-mail message to the registered e-mail addresses of the previous performer in all roles of the instance. In difference to EmailAllPerformers this exclude the ones where the participant of the role has been substituted by a new performer, then only the newest performer in that role gets the e-mail.

Send E-mail Business Component variables

Accessing and sending process information in your e-mail is one of the more powerful features of the Send E-mail Business Component. Variables are easy and are written plain text with dollar-signs ($) before and after the variable.

For example you can write in your subject:

“Thank you, we have received your registration for $$

In the e-mail subject the e-mail will replace $$ with the instance name of the created process instance.

In the same way you can add variables in the Message field as well. The available variables that you can use can be seen in the list below.

Instance variables


Application variables


Task variables


Form field content
