# Mailout Folders Every mailout in UbiQuity lives inside a Mailout Folder. Use folders to group similar mailouts together — for example, by campaign type, audience, or opt-in category. > **Note:** If you delete a Mailout Folder, all mailouts inside it will also be deleted. *** ### Mailout Folder filters You can apply a filter to a Mailout Folder so that it is automatically applied to every mailout created within that folder. This is particularly useful when you have multiple opt-in fields in your database — for example, *Opted In Marketing*, *Opted In Newsletter*, and *Opted In Product Updates*. By creating a folder for each communication type and setting the appropriate filter on each folder, you ensure the right contacts are always targeted without having to re-apply the filter each time. Example setup: * Create a folder called *Marketing Emails* with a filter of *Opted In Marketing = Yes* * Create an Update Form with the *Opted In Marketing* field on it * Add the link to that form in the email templates used for marketing sends * When a recipient clicks the opt-out link and sets *Opted In Marketing = No*, they will automatically be excluded from future mailouts in that folder You can still apply additional filters at the individual mailout level on top of the folder filter. *** ### Mailout Folder reports Folder-level reports let you view and compare performance across multiple mailouts in the same folder. When creating a report, select the mailouts you want to include. You can change which mailouts are included after the report is created using the **Modify Report** option. Folder reports include: * An **Overview** page showing combined stats across all included mailouts * A **Comparison** page for side-by-side comparison of individual mailout performance — useful for subject line testing and campaign analysis * A dropdown to view the individual report for each mailout Reports can be shared via a link. Anyone with the link can view the report without logging in to UbiQuity. No personally identifiable information is shown. The link is not published anywhere — access requires knowing the URL. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
