# Overview

> Learn how to create and run AI-powered email campaigns in Callers, where your AI agent sends, reads, and replies to emails automatically.

## What Are Email Campaigns?

Email campaigns bring Callers' AI agents to your inbox. Instead of calling or
texting, your AI agent sends personalized emails, reads the replies it receives,
and responds automatically - following the script and goals you define, just
like your voice and text campaigns.

Email is ideal for longer-form outreach, professional follow-ups, and any
audience that prefers to communicate in writing. Because conversations happen
asynchronously, your contacts can reply whenever it suits them, and your AI agent
picks the conversation back up the moment a reply arrives.

## Key Benefits

    context, carrying the conversation forward toward your goal.

    Connect several sending addresses and let Callers distribute emails
    across them to protect deliverability and sender reputation.

## How Email Campaigns Work

<Steps>
  <Step title="Connect Your Mailboxes">
    Connect the email accounts your campaign will send from - Gmail, Outlook,
    Yahoo, or any provider over SMTP. See
    [Email Setup](/documentation/email-campaigns/email-setup) for details.
  </Step>

  <Step title="Build Your Script">
    Use the same script builder you already know to define the conversation flow,
    what the AI agent should achieve, and how it should respond to replies.
  </Step>

  <Step title="Set a Default Subject and Signature">
    Choose the subject line for the first email and add a signature so every
    message looks polished and professional.
  </Step>

  <Step title="Upload Contacts">
    Add your contact list. For email campaigns, each contact needs an email
    address. See [Uploading Contacts](/documentation/using-callers/uploading-contacts).
  </Step>

  <Step title="Launch">
    Start the campaign. The AI agent sends the first email, watches for replies,
    and handles the conversation from there.
  </Step>
</Steps>

## Supported Email Providers

Connect the mailboxes you already use. Callers supports the major providers as
well as any custom mail server over SMTP.

  <Card title="Any Provider (SMTP)" icon="server">
    Connect any other email provider or custom mail server using SMTP for
    sending and IMAP for reading replies.

## Sending and Replying

* **Outbound sending** - The AI agent sends the first email to each contact
  using one of your connected mailboxes.
* **Inbound replies** - When you connect a mailbox for receiving, Callers watches
  that inbox and hands new replies to the AI agent, which responds in the same
  email thread.
* **Threaded conversations** - Replies stay within the original email thread, so
  the exchange reads naturally for your contact.

<Info>
  To have your AI agent read and reply to responses, make sure the mailbox is
  connected for **both** sending and receiving. A send-only mailbox can deliver
  emails but won't pick up replies.

## Getting Started

<Steps>
  <Step title="Create an Email Campaign">
    From your dashboard, click **New Campaign** and choose **Email** as the
    campaign type.
  </Step>

  <Step title="Connect and Select Mailboxes">
    Open **Mailboxes** and connect the addresses you want to send from and
    receive replies on.
  </Step>

  <Step title="Configure Subject, Signature, and Follow-Ups">
    Set your default subject line, add a signature, and decide how follow-ups
    should behave.
  </Step>

  <Step title="Upload Contacts and Launch">
    Add your contact list and start the campaign.
  </Step>
</Steps>

<Info>
  Email campaigns share the same contact management, analytics, and reporting as
  your voice and text campaigns. If you already run campaigns in Callers, email
  will feel familiar from day one.
