Missing email activity when SendEmail failed: EMAIL_ADDRESS_BOUNCED, The target object email address is currently marked as bounced

Question

Salesforce recently stopped creating email activity records for emails which failed because they bounce.

Below is the error I am getting:

SendEmail failed. First exception on row 0; first error: EMAIL_ADDRESS_BOUNCED, The target object email address is currently marked as bounced.: [targetObjectId, ...]

When I use the below code:

public static Messaging.SendEmailResult sendEmail(Id whatId, Id emailTemplateId, String emailTemplateDeveloperName, String orgWideEmailId, Id targetObjectId, String emailAddress, Boolean saveActivity) {

    Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

    if (String.isNotBlank(emailTemplateId)){

        mail.setTemplateId(emailTemplateId);

    } else if (String.isNotBlank(emailTemplateDeveloperName)){

        mail.setTemplateId(getEmailTemplateId(emailTemplateDeveloperName));    
    }

    if (String.isNotBlank(whatId)){
        mail.setWhatId(whatId);
    }

    if (String.isNotBlank(targetObjectId)){

        mail.setTargetObjectId(targetObjectId); 

    } else if (String.isNotBlank(emailAddress)) {

        mail.setToAddresses(new String[] {emailAddress}); 
    }

    if (String.isNotBlank(orgWideEmailId)){
        mail.setOrgWideEmailAddressId(orgWideEmailId); 
    }

    mail.setSaveAsActivity(saveActivity);
    mail.setOptOutPolicy('FILTER');

    Messaging.SingleEmailMessage[] messages = new List<Messaging.SingleEmailMessage>();
    messages.add(mail);

    Messaging.SendEmailResult[] results = Messaging.sendEmail(messages);

    handleEmailResults(results);

    return results[0];
}

private static void handleEmailResults(Messaging.SendEmailResult[] results) {

    for(Messaging.SendEmailResult result :results) {                

        if(!result.IsSuccess()) {                    
            List<Messaging.SendEmailError> errors = result.getErrors();
            if (errors.size() > 0){
                Messaging.SendEmailError err = errors[0];
                System.debug(err.getMessage());       
            }                   
        }
    } 
}

I've doubled checked, and setSaveAsActivity is definitely being set to true

Question

1. Why aren't the email activities being created?
2. What can I do to fix it?

Answer 1

Why aren't the email activities being created?

Emails that fail to send are not saved as an activity. For example, if it is missing a subject, recipient, etc, it will not be saved anywhere.

What can I do to fix it?

You need to check if it failed, and manually save activities if you want to record the activity.
