Send custom content templates or drag and drop editor emails via the [SparkPost](🔗) channel action, from a Flow (One-time Send, Recurring, or Triggered).
Before you begin
Review [Flows and Channel Actions: How They Work](🔗).
If you haven't already, [have an engineer connect your SparkPost account to Simon](🔗).
# Action Types
|Send Email to Contact||Send an email to your contact via your existing Sparkpost account.||✅||✅||❌||✅|
# Field Descriptions
## Email Details (Required)
Click **View Simon Templates in Content** to open the [Content Editor](🔗) in a new tab for the template you've selected. If you haven't selected anything, the template list opens for you to view and open an existing template.
The template you chose will populate the subject line, or you can enter a new subject line for your email or click **\</>** to customize with Jinja:
## Contact Addresses
The template you chose populates these fields, or you can edit them directly in the channel action:
** From Email**: The email you want to appear in the from field in the delivered email (not necessarily the email you want replies delivered to.
**From Name** (Optional): Sometimes called a [friendly from name](🔗).
**Reply-To Email** (Optional): Address you want replies routed to should a contact reply to your message. If left blank, Simon Mail defaults routing replies to the From Address.
## UTM Parameters (Optional)
UTM Parameters automatically append these [Google Analytics key/value pairs](🔗) to the query string of all the hyperlinks in the selected template so that you do not have to hard code those parameters into your hyperlink code one by one yourself.
### Disable Default UTM Parameters or Customize Defaults
We include UTM parameters by default, but you can choose to disable this feature either by flow, or globally.
To disable the UTM parameters for the **current flow only**, add the _SparkPost_ action then toggle the ** Add UTM parameters to links** option to off:
To disable UTM Parameters globally _or_ customize your UTM defaults:
From the left navigation expand **Admin Center** the click **Settings**.
Click **UTM Tracking**.
Either toggle **Add UTM parameters to all campaign links** to off (no UTM parameters will display in any campaign creation) _or_ update the defaults you want to display in your campaign creation.
### Parameter Definitions
[Read parameter definitions here](🔗). Simon specific defaults are:
|utm_source||defaults to `|
|utm_medium||defaults to `|
|utm_campaign||Flows inherit the flow name, Journeys inherit the step name|
## Metadata (Optional)
Include a **Name** and **Value**.
Toggle the **Bell** on/off to alert if there's empty [Custom context basics](🔗).
You can also copy the name/value pairs from a previous flow or journey:
Click **Edit** to select and preview the value directly from Contacts, Lookups, or Blocks.
Click the **Trash Can** to delete.
You can add an unlimited number of metadata name/value pairs. Any metadata you add here flows through the channel and then back to SparkPost for you to use there.
## Frequency Cap (Optional)
**Max Sends per Period** Choose how many times (1-5, or Unlimited) to send the email within the period you choose.
**Period**: Choose from a number of increments from 1-365 days, or choose N/A.
## Send a Test (Optional)
### Test Recipient Contact
Choose an email address to, optionally, _send a live test_ email to and preview your send. Note, UTM parameters are not appended in test sends.
