Connecting Subdomains to HubSpot for Email Sending

A Step-by-Step Guide to Configure Your Subdomain for HubSpot Email Deliverability

Issue:

You may experience difficulties when trying to set up a subdomain as an email sending domain in HubSpot, especially if your main website is hosted with a different provider.

Solution:

Follow these steps to successfully connect your subdomain to HubSpot for email sending:

1. Verify Your DNS Settings

  • Start by checking the DNS records for your subdomain. You’ll need to configure a CNAME record that points to HubSpot.
  • If necessary, don't forget to add a TXT record for DMARC. This will help authenticate your emails and improve deliverability.

2. Check Hosting Provider Configuration

  • Ensure that the settings from your main site’s hosting provider do not conflict with HubSpot's requirements. This includes verifying that any existing records do not hinder the connection.

3. Consult HubSpot’s Email Authentication Guide

  • For detailed steps on connecting and verifying your email sending domain, refer to HubSpot's guide on email authentication. This guide provides in-depth instructions to help you through the process.

Summary:

By ensuring you have the correct DNS records and confirming that your hosting provider settings align with HubSpot's requirements, you can successfully configure your subdomain as an email sending domain in HubSpot. If you continue to experience issues, please consult HubSpot’s extensive guides or reach out to HubSpot support for further assistance.
