# Overview

A **Follow-up campaign** is a type of web push campaign available in PushPushGo. It enhances communication with users by allowing you to send a **series of notifications** or **increase the reach** of a specific message.

Each Follow-up campaign consists of a **source campaign** and one or more **follow-ups** that are sent after the source campaign.

You can use a follow-up strategy in two main ways:

1. **Create a sequence of notifications** to maintain ongoing user engagement.
2. **Increase the reach of a campaign** by sending follow-ups to subscribers who did not receive the original message — for example, due to technical issues or temporary unavailability at the time of the initial send.

This feature helps ensure **broader message delivery** and supports **multi-step communication strategies** for more effective user engagement.
