EmailMessage

Represents an email in Salesforce.

Supported Calls

create(), delete(), describeLayout(), describeSObjects(), getDeleted(), getUpdated(), query(), retrieve(), search(), undelete(), update(), upsert()

Special Access Rules

EmailMessage is only available for orgs that use Email-to-Case or Enhanced Email, which is automatically enabled for most customers.

To use reply and forward functionality, FromAddress must specify an email address that exists in EmailMessageRelation, with a RelationType of FromAddress.

The Status field is mostly read-only. You can change the status only from New to Read.

update() is supported when an email record is in Draft status, and IsPrivateDraft is false. It’s also supported if the email status is Draft, IsPrivateDraft is true, and CreatedBy is associated with the current user. When the email record isn’t in Draft status, the IsExternallyVisible field and custom fields only can be updated.

Access to an email message depends on the associated object. The user who created the email is specified in CreatedById and always has access, unless that user is a guest user. Guest users have read access if the message is marked as IsExternallyVisible.

The object that’s used to determine access differs for Email-to-Case and Enhanced Email.

Email-to-Case—When Email-to-Case is enabled and the email is Case-based (the ParentId field is Case), access depends on the user’s access to the related Case record. If the email message is a draft, only the user in the CreatedById field or users with the Modify All Data permission can access it.
Enhanced Email—Access is activity-based. The ActivityId field specifies an associated Task record. You can control access to activity-based objects with the Access Activities permission. Users with the Modify All Data permission can also access the message.

When you use the API to insert EmailMessage records in bulk, the same access rules apply: access is based on cases in ParentId fields or by tasks in ActivityId fields. When inserting a single record, set the CreatedById field to the user performing the operation or leave it blank.

Fields

Field	Details
ActivityId	Type reference Properties Create, Filter, Group, Nillable, Sort Description ID of the activity that is associated with the email. Usually represents an open task that is created for the case owner when a new unread email message is received. ActivityId can only be specified for emails on cases. It’s auto-created for other entities.
BccAddress	Type string Properties Create, Filter, Nillable, Sort, Update Description A string array of email addresses for recipients who were sent a blind carbon copy of the email message. Include only email addresses that aren’t associated with Contact, Lead, or User records in Salesforce. If the recipient is a contact, lead, or user, add their ID to the BccIds field instead of adding their email address to the BccAddress field. When adding their ID, the email message is automatically associated with the contact, lead, or user. For an Experience Cloud site user who isn’t the sender of the email, this field returns null. You can’t send emails unless there’s at least one recipient.
BccIds	Type JunctionIdList Properties Create, Update Description A string array of IDs for contacts, leads, and users who were sent a blind carbon copy of the email message. Each ID is linked to an EmailMessageRelation record, which represents the relationship between an email message and a Contact, Lead, or User record. For an Experience Cloud site user who isn’t the sender of the email, this list is empty. Adding a JunctionIdList field name to the fieldsToNull property deletes all related junction records. This action can’t be undone. Warning
CcAddress	Type string Properties Create, Filter, Nillable, Sort, Update Description A string array of email addresses for recipients who were sent a carbon copy of the email message. Include only email addresses that aren’t associated with Contact, Lead, or User records in Salesforce.

CcIds	Type JunctionIdList Properties Create, Update Description A string array of IDs for contacts, leads, and users who were sent a carbon copy of the email message. Each ID is linked to an EmailMessageRelation record, which represents the relationship between an email message and a Contact, Lead, or User record.

ClientThreadIdentifier	Type string Properties Create, Filter, Nillable, Sort, Update Description A value used by third-party email clients to identify which thread an email belongs to, stored only when found in email headers.

For example, if Email-to-Case detects an Outlook-specific header called Thread-Index, it stores its first 22 bytes in uppercase hexadecimal format in this field. Available in API versions 56.0 and later.
ContentDocumentIds	Type JunctionIdList Properties Create, Update Description A string array of IDs for content documents, such as files and attachments, that are associated with an email.

Usage

If your org uses Email-to-Case, a case is created when an email is sent to one of your company’s addresses. The email, which is related to the case by the ParentID field, is stored as an EmailMessage record. When users view the email, they see the EmailMessage record.

If your org uses Enhanced Email, each email is stored as an EmailMessage record and a Task record. When users view an email, they see the EmailMessage record.

Sample Code—Apex

This sample logs email activity in Salesforce.

1// if EnhancedEmail Perm is not enabled, continue logging the email as a task
2
3// if EnhancedEmail Perm is enabled, create an EmailMessage object
4EmailMessage emailMessage = new EmailMessage();
5emailMessage.status = '3'; // email was sent
6emailMessage.relatedToId = '006B0000003weZGIAY'; // related to record e.g. an opportunity
7emailMessage.fromAddress = 'sender@example.com'; // from address
8emailMessage.fromName = 'Dan Perkins'; // from name
9emailMessage.subject = 'This is the Subject!'; // email subject
10emailMessage.htmlBody = '<html><body><b>Hello</b></body></html>'; // email body
11// Contact, Lead or User Ids of recipients
12String[] toIds = new String[]{'003B000000AxcEjIAJ'}; 
13emailMessage.toIds = toIds;
14// additional recipients who don’t have a corresponding contact, lead or user id in the Salesforce org (optional)
15emailMessage.toAddress = 'emailnotinsalesforce@toexample.com, anotherone@toexample.com';
16insert emailMessage; // insert
17
18// Add Email Message Relation for id of the sender
19EmailMessageRelation emr = new EmailMessageRelation();
20emr.emailMessageId = emailMessage.id;
21emr.relationId = '005B0000003qHvOIAU'; // user id of the sender
