Yes, as long as the email address you select as the From in your marketing emails also contains that same subdomain as your connected email sending domain.
What if I connect a subdomain as my email sending domain, but still send emails using my root domain?
Simply put: your email sending domain won't be used.
- Our logic looks for a match between the domain of the From email address selected in your email draft and the connected email sending domain in the Domain Manager. If you successfully connect info.domain.com as your email sending domain, the From address selected in your email draft will also need to contain @info.domain.com, such as firstname.lastname@example.org
- if you connect info.domain.com and use a From address in your email draft containing @domain.com, recipients will not see your email sending domain, so they will see the default which is “via shared.hubspot.com"
Let's get technical
In most situations, connecting a subdomain for this purpose isn’t necessary - it’s only used for DKIM email authentication and HubSpot is still the domain behind-the-scenes sending the email, so using a subdomain vs. root doesn't make any difference reputation-wise.
