# Subscriber Management

> Manage subscribers, imports, exports, custom fields, tags, double opt-in, and dynamic segments.

## Guides
- [Subscribers](https://mailrith.com/docs/subscribers.md): The Subscribers page is the operating hub for your subscriber list — search, status filtering, bulk actions, CSV imports and exports, and per-subscriber activity timelines all live here.
- [Subscriber Imports, Exports, and Bulk Actions](https://mailrith.com/docs/subscriber-imports-exports.md): Imports, exports, and bulk actions help you move and update large subscriber groups without manual row-by-row work. This guide explains how to prepare clean CSV files, map fields, monitor background jobs, and avoid accidental broad changes.
- [Custom Fields](https://mailrith.com/docs/custom-fields.md): Custom fields are the shared data schema for your workspace — define them once and they become available across subscriber records, forms, segmentation rules, automation conditions, and email merge variables.
- [Tags](https://mailrith.com/docs/tags.md): Tags are the fastest way to categorize subscribers — apply them through imports, forms, automations, and magic links, then use them as targeting filters across every send surface in Mailrith.
- [Double Opt-In](https://mailrith.com/docs/double-opt-in.md): Double opt-in helps prove that a subscriber controls the email address they submitted. In Mailrith, it is configured on tags so each signup category can have its own confirmation email and success experience.
- [Segments](https://mailrith.com/docs/segments.md): Segments define reusable subscriber rules that stay current without manual maintenance — use them to target broadcasts, filter sequence emails, and build complex nested conditions from simple building blocks.
