Email Campaign Sender Setup Guide

Setting up proper sender information is crucial for successful email campaigns. This guide covers essential steps for creating and authenticating your sender details.

Key Requirements:

  • Use custom domain email addresses (avoid free services like Gmail)
  • Authenticate both email address and domain
  • Provide accurate sender information to comply with CAN-SPAM regulations
  • Maximum of 10 sender information sets allowed

Creating Sender Information:

  1. Navigate to Email Campaign Settings
  2. Select Sender Information
  3. Click Add Sender
  4. Enter sender name (visible to recipients)
  5. Add sender email address (preferably custom domain)

Authentication Process:

  1. Email Authentication
  • Check inbox for authentication code
  • Enter code in Set Sender Information window
  • For missing emails, check spam folder for [email protected]
  1. Domain Authentication
  • Squarespace domains: Automatically authenticated
  • Third-party domains: Requires manual authentication
  • DMARC policy must allow authentication

Best Practices for Domain Setup:

  1. Register domain through Squarespace
  2. Set up custom email with Google Workspace
  3. Create and authenticate sender information

Free Email Service Limitations:

  • Major providers restrict mass email delivery
  • Some free email domains are blocked
  • Squarespace generates alternative sending addresses for Gmail users
  • Avoid using addresses from: aol.com, yahoo.com, icloud.com, etc.

Managing Sender Information:

  • Edit sender name through Email Campaign Settings
  • Email addresses cannot be modified (create new sender instead)
  • Delete unused sender information as needed

Following these guidelines ensures better deliverability rates and prevents your campaigns from being marked as spam.
