Show html email status under account

Shanker

As per this reference, HTML Email Status Related list is available only for Leads, Contacts and Person Accounts which has the standard email field.

if your question is about adding it to Person Accounts then you can go to Person Account page layout and add it.

but if its for normal Accounts which doesn't have a standard Email field, you cannot add this related list directly. You need to build a visualforce page which can display the related list from the associated Contact and then you can add this VF page into the Standard Account page layout.

It looks like you cannot query the object directly but you could query the parent of the EmailStatus, for example the contact and it's children records and filter it by account:

Select Name, AccountId, (Select Id, EmailTemplateName From EmailStatuses) From Contact WHERE AccountId = '0018000000QbytrAAB'
