Introduction

Contacts are the people you send emails to in AutoSend. Each contact has a unique email address and associated data like name, location, or any other information you’ve added through fields.

Contacts can be organized using Lists or Segments for better targeting.

All Contacts

The All Contacts list shows every contact you’ve ever added to your account.

Contacts can come from:

• Manual additions
• Imported via CSV
• API integrations
• Sign-ups or form submissions

You can filter and search contacts, and view detailed insights for each.

Contact Details

Clicking on any contact opens their Contact Details page, where you can view:

• Details: Basic information (email, name, etc.), Reserved and Custom Fields.
• Lists & Segments: All the lists and segments the contact belongs to
• Unsubscribes: The kind of emails a particular user has unsubscribed from.
• Email Activity: The email history of a particular user.

Custom Fields

Custom fields let you store additional information beyond the reserved ones — for example, “Company,” “Plan Type,” or “Signup Date.”

They can be text, number, or date fields

You can use these in both marketing campaigns and transactional emails to personalize your content using variables like {{custom_field_name}}.
