Use a Subdomain When Sending Emails

This guide outlines the steps for sending emails using a subdomain and managing replies in both HubSpot and Mailchimp. Using a subdomain for bulk email sends helps improve the sender score and protects the email reputation of the main domain.

Notes

Using a subdomain for bulk email sends helps improve the sender score and protects the email reputation of the main domain.
The subdomain email address is stankruss@mailer.expocentric.com.au.
For Mailchimp, always update the From Name to Stan Kruss and the From Email to the subdomain address before sending.
For HubSpot sequences, always select the subdomain email from the 'From' address dropdown before sending.
Mailchimp replies can be managed via the Mailchimp inbox or directly via Outlook if CC'd.
HubSpot replies are accessible via the shared Outlook inbox or the contact's activity timeline in HubSpot.
