# Send an Email via Mailjet Plugin
You can send emails to your users from Acho apps via [Mailjet](https://www.mailjet.com/) Plugin. You'll need a free Mailjet account to use Mailjet send API service.
### 1. Find your Mailjet API Key and Secret Key
Go to account setting -> Rest API -> [API Key Management (Primary and Sub-account)](https://app.mailjet.com/account/apikeys) to acquire your api key and secret key.
### 2. Create or enter an app[](https://docs.retool.com/queries/guides/emails#1-create-an-app)
If you haven't created an app yet, [log in Acho](https://app.acho.io/main/apps) and click **Create new Data App**. Create a blank app or start from a template.
### 3. Install Mailjet service
Find [plugin store](https://docs.acho.io/app-builder/app-construction/plugin-store) on the side bar, click on Mailjet API, install the API and add to API services. Once it is installed and added to API services, you can find it as an [action](https://docs.acho.io/app-construction/interactions/add-an-interaction#actions) in API services category.
### 4. Add an input element and add [action flow](https://docs.acho.io/app-construction/interactions#action-flow)
Drag an [input](https://docs.acho.io/app-builder/app-construction/elements/form-elements/input) element from elements list, and add **event** -> **action** to trigger the Send Email Service. In this example, I use Press Enter to trigger the action. Then fill all these fields required for sending an email.
* apiKey: A string field that requires your API key, which serves as an authentication mechanism for accessing Mailjet's services.
* apiSecretKey: A string field for the secret API key that corresponds to your API key, used to enhance security and verify your API requests.
* fromEmail: The sender's email address, indicating who the email is being sent from.
* fromName: The sender's name or the display name associated with the sender's email address.
* toEmail: The recipient's email address, indicating who will receive the email.
* toName: The recipient's name or a display name associated with their email address.
* subject: A string that holds the subject or topic of the email, conveying the main purpose or content of the message.
* textPart: Plain text part of the email's content, which is typically shown when HTML rendering is unavailable.
* htmlPart: Used to store the HTML-formatted version of the email's content, enabling rich formatting and styling for the email's appearance.
{% hint style="info" %}
**apiKey**, **apiSecretKey** is what we get from Step 1
The **fromEmail** must be an approved sender connected to your Mailjet account.
{% endhint %}
{% hint style="info" %}
You can use `${event.value}` in **textPart** so that what you entered in input element will be sent as the text part of the email.
{% endhint %}
{% hint style="info" %}
You can use a form to collect multiple input and control all these parameters seamlessly. See [use-custom-form-container-to-collect-user-inputs](https://docs.acho.io/app-builder/popular-use-cases/use-custom-form-container-to-collect-user-inputs "mention") for details.
{% endhint %}
{% hint style="info" %}
If you want to automate the send email process, consider using an auto-updated Query Node to trigger the **Send an email** action, and use [Action condition](https://docs.acho.io/app-builder/app-construction/interactions/add-conditions-to-interactions) to control it.
{% endhint %}
### 5. Test
Go to [preview](https://docs.acho.io/app-builder/preview) to test the interaction. In this example, I used the input value as the text part of the email.\
