Send Email Connector

Overview
The Send Email connector is part of the Email package. When you add the Send Email connector to your Process model and then reference a Screen for email body content, ProcessMaker can send emails during Requests. The Send Email connector can email a specified email address when that Send Email connector triggers in a Request's workflow.
The Send Email connector adds the following components when the Email package is installed:
Process Modeler: The Send Email connector adds the Send Email connector below the BPMN 2.0 elements in the panel to the left of the Process Modeler canvas. See the following sections in this topic:
​Add a Send Email Connector to the Process Model​
​Configure a Send Email Connector​
Screens Builder: The Send Email connector adds a new Screen type called Email. Select the Email Screen type when creating a new Screen. See Email Screen type.
The email recipient's name and email address can be specified in one of the following ways when configuring the Send Email connector:
Plain text
A Variable Name setting value using mustache syntax, for example {{ email_recipient }} and {{ email_address }}, respectively
A Magic Variable value, specifically {{ _user.fullname }} and {{ _user.email }}, respectively
Package and Permissions Required
The Send Email package must be installed to use the Send Email connector.
Furthermore, your user account or group membership must have the following permissions to configure a Send Email connector to the Process model unless your user account has the Make this user a Super Admin setting selected:
Processes: Edit Processes
Processes: View Processes
See the Process permissions or ask your Administrator for assistance.
Add a Send Email Connector to the Process Model
​A package and permissions are required to do this.
Follow these steps to add a Send Email connector to the Process model:
1.​View your Processes. The Processes page displays.
2.​Create a new Process or click the Open Modeler icon
to edit the selected Process model. Process Modeler displays.
3.Locate the Send Email connector in the Elements and Connectors palette that is to the left of the Process Modeler canvas. If the Hide Menus button​
is enabled, the Elements and Connectors palette displays the Send Email connector's icon
.
 
4.Drag the connector into the Process model canvas where you want to place it. If a Pool element is in your Process model, the Send Email connector cannot be placed outside of the Pool element.
Send Email connector
After adding the Send Email connector, consider adding the following Boundary-type Process model elements to design business solutions when your best-case scenarios don't happen:
​Boundary Timer Event element (Don't know what that is?)
​Boundary Error Event element (Don't know what that is?)
​Boundary Signal Event element (Don't know what that is?)
​Boundary Conditional Event element (Don't know what that is?)
​Boundary Message Event element (Don't know what that is?)
After the connector is placed into the Process model, you may adjust its location in the following ways:
Move the connector by dragging it to a new location.
​Select the connector with other elements and/or connectors, and then move them collectively by dragging them to new locations in relation to one another.
​Align and/or distribute the connector in relation to other selected elements and/or connectors.
Moving a Send Email connector has the following limitations in regards to the following Process model elements:
Pool element: If the Send Email connector is inside of a Pool element, it cannot be moved outside of the Pool element. If you attempt to do so, Process Modeler places the Send Email connector inside the Pool element closest to where you attempt to move it.
Lane element: If the Send Email connector is inside of a Lane element, it can be moved to another Lane element in the same Pool element. However, the Send Email connector cannot be moved outside of the Pool element.
Customize the Appearance of a Send Email Connector Connector
Customize the Send Email connector's appearance in the following ways:
Customize the color of the connector, icon, and label, which by default display as black-colored. See Change a Send Email Connector's Color.
Customize the icon that displays in the connector. Send Email connectors display the
icon in the shape by default. See Change a Send Email Connector's Icon.
After a Send Email connector is added to a Process model, optionally customize these aspects of its appearance. Each Send Email connector's appearance may only be changed individually.

Loop Characteristics Panel Settings
Specify Characteristics to Perform Multiple Instances of the Task
Use the Loop Characteristics panel settings to specify how to perform multiple instances of this element. The following loop modes are available for this element:
No Loop Mode: Select the No Loop Mode option to perform this element's Task only once.
Loop: Select the Loop option to sequentially repeat this element's Task multiple times until an exit condition is True. This is useful when a Task should be performed multiple times with the same set of data, such as, processing a credit card payment. This loop mode has the following characteristics:
The element's Task is repeated until the exit condition is True or the maximum iterations limit is reached.
At any given time, only one instance of the Task is active. The subsequent instance does not begin until the current instance completes.
The same exit condition evaluates at the end of each instance; however, value(s) of the Request variable(s) used in the exit condition can change during an instance resulting in the exit condition to eventually evaluate as True.
If any one instance of that Task does not complete, workflow pauses.
All active instances are terminated if an interrupting boundary-type event element triggers.
An element configured in this mode shows the Loop icon
 in Process Modeler.
Multi-instance (Parallel): Select the Multi-instance (Parallel) option to perform this element's Task multiple times in parallel a fixed number of times. This is useful when performing any action in bulk, such as sending an email to several people. This loop mode has the following characteristics:
Instances of the Task are governed by the size of an array-type Request variable where a new instance is created for each item in this variable. For example, an array with 10 items will create 10 parallel instances of this Task that each contains data from its respective array index.
All instances begin simultaneously when this element triggers; however, they perform their Task independently of each other.
The Task as a whole completes when all instances are complete.
The output from each instance can either be saved in the source Request variable or a new array-type Request variable.
All active instances terminate if an interrupting boundary-type event element triggers.
An element configured in this mode shows the Multi-instance (Parallel) icon
 in Process Modeler.
Multi-instance (Sequential): Select the Multi-instance (Sequential) option to perform this element's Task multiple times sequentially a fixed number of times or until an exit condition is True. This is useful when sequentially repeating a Task multiple times but with a different set of data each time. This loop mode has the following characteristics:
Instances of the Task are governed by the size an array-type Request variable where a new instance is created for each item in this variable. For example, an array with 10 items will create 10 parallel instances of this Task that each contains data from its respect array index.
At any given time, only one instance of the Task is active. The subsequent instance does not begin until the current instance completes.
At the end of each instance an exit condition evaluates and the loop activity halts if the exit condition is True.
The Task as a whole completes when all instances are complete.
The output from each instance can either be saved in the source Request variable or a new array-type Request variable.
All active instances terminate if an interrupting boundary-type event element triggers.
An element configured in this mode shows the Multi-instance (Sequential) icon
in Process Modeler.
