# Manage tags

> Use tags to classify contacts

## What is a tag?

A tag is a label for organizing and finding contacts. Use tags for known attributes, similar to labels in a CRM.

## Use tags in a campaign

When creating a campaign, select recipients by tag. If a contact belongs to multiple selected tags, Sendify counts and sends to that contact only once.

> [!TIP]

> Use a consistent naming convention such as `Region-North America` or `Industry-SaaS`.
