# Add Attachments to a Visualforce Email Template You can add attachments to your Visualforce email templates. Each attachment is encapsulated within a single `` component. Code within `` can be a combination of HTML and Visualforce tags. The example in [Create a Visualforce Email Template](/docs/platform/salesforce-pages-developers-guide/guide/pages-email-templates-creating.md) shows how to create a Visualforce email template by iterating through some data and displaying it to an email recipient. 1. To create an attachment that contains the data from the example, use the `` component. This attachment is an unformatted text file. ```apex_page

Dear {!recipient.name},

Attached is a list of cases related to {!relatedTo.name}.

For more detailed information, log in to Salesforce.com Case Number: {!cx.CaseNumber} Origin: {!cx.Origin} Creator Email: {!cx.Contact.email} Case Number: {!cx.Status} ``` 2. To define the name of the attached file, set the `filename` attribute. While it’s good practice to define an easily identifiable name, it isn’t required. If you leave the name undefined, Salesforce generates a name for you. A file name without an extension defaults to a text file. To render the attached file as a CSV, add the .csv file extension to the file name. ```visualforce {!cx.CaseNumber} {!cx.Origin} {!cx.Contact.email} {!cx.Status} ``` To render the attached file as an HTML file, add the .html file extension to the file name. ```visualforce

Case Number	Origin	Creator Email	Status
{!cx.CaseNumber}	{!cx.Origin}	{!cx.Contact.email}	{!cx.Status}

``` Although you can define only one file name for every `` component, you can attach multiple files to an email. 3. To render the attachment as a PDF, set the [`renderAs`](/docs/platform/salesforce-pages-developers-guide/guide/pages-output-pdf-renderas.md) attribute to `"PDF"`. Before using this feature, review the [Visualforce PDF Rendering Considerations and Limitations.](/docs/platform/salesforce-pages-developers-guide/guide/pages-output-pdf-considerations.md) ```visualforce

You can display your {!relatedTo.name} cases as a PDF:

Case Number	Origin	Creator Email	Status
{!cx.CaseNumber}	{!cx.Origin}	{!cx.Contact.email}	{!cx.Status}

``` :::note The `renderAs` attribute accepts any MIME type as a valid value. However, Visualforce supports only PDF rendering. Visualforce doesn’t generate other file formats. It only sets the `Content-Type` field of the HTTP response header to the specified MIME type. Some file formats, such as .xlsx, can fail to render. ::: 4. You can also style your attachment with images or style sheets. Styles are associated with attachments [the same way as they are in Visualforce email templates](/docs/platform/salesforce-pages-developers-guide/guide/pages-email-templates-stylesheets.md), either as inline code or by using a custom component. Attachments rendered as PDFs can reference static resources through the [`$Resource` global variable](/docs/platform/salesforce-pages-developers-guide/guide/pages-resources.md), so you can refer to an image or style sheet within the body of the PDF. For example, this attachment includes a logo in the PDF: ```visualforce

... ``` This attachment references a style sheet that’s saved as a static resource: ```visualforce ... ``` :::note Referencing static resources on a remote server can increase the time it takes to render a PDF attachment. You can’t reference remote resources when creating PDF attachments in an Apex trigger. Doing so results in an exception. :::
