[SalesForce] Check For Special Characters in Emails

I would like to clarify something that, the email is not sent until the Apex transaction is committed.

Here are two links related to this situation:- http://help.salesforce.com/HTViewSolution?id=000006765 https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_forcecom_email_outbound.htm

Here is code for forcefully sendEmail to Logged In User.

trigger triggerOnContact on Contact (before insert, after insert) {

    Map<String,Contact> existingContactMap= new Map<String,Contact>(); //creating Map of contact with email you, because you can use other field while sending email
    Map<String,String> emailMsg = new Map<String,String>();

if(trigger.isBefore){
    Set<String> emailSet =new Set<String>();
    for(Contact contactObj : trigger.new){ 
        if(String.isNotBlank(contactObj.Email)) emailSet.add(contactObj.Email); 
    }
    For(List<Contact> contacts : [SELECT Name, Email From Contact WHERE Email in: emailSet ]){
        for(Contact contactObj : contacts){
            if(!existingContactMap.containsKey(contactObj.Email)){
                existingContactMap.put(contactObj.Email,contactObj);
                emailMsg.put(contactObj.Email,contactObj.Name);
            }
        }
    }
    List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();
    for(Contact contactObj : trigger.new){
        if(String.isNotBlank(contactObj.Email)){
            if(!existingContactMap.containsKey(contactObj.Email)){
                contactObj.IsContactExistWithEmail__c=true;//for deleting records
                mails.add(sendErrorEmail(contactObj.Email,existingContactMap, emailMsg));
                // contactObj.addError('The Email \''+ contactObj.Email + '\' is already available in the Contact.');
            }
        }
    }
    if(mails.size()>0)
        Messaging.sendEmail(mails); 
} else{
    List<Contact> contactToDelete = new List<Contact>();
    for(Contact contactObj : trigger.new){
        if(contactObj.IsContactExistWithEmail__c)
            contactToDelete.add(new Contact(id=contactObj.id));
        }
        if(contactToDelete.size()>0)
            delete contactToDelete;
    }

/** * method is used to creating Emails **/ private Messaging.SingleEmailMessage sendErrorEmail(String email,Map existingContactMap1, Map emailMsg1){ List toAddresses = new List{UserInfo.getUserEmail()} ; //getting Login user's Email System.debug(toAddresses); //Sending Mail Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage() ;

// Assign the addresses for the To and CC lists to the mail object
mail.setToAddresses(toAddresses);

//Email subject to be changed
mail.setSubject('Contact already exist with Email');

//Body of email
mail.setHtmlBody('Hi '  + emailMsg1.get(email)
                        +',\nBelow Email is does not exist in Contact records.\nEmail:'+email
                        +'\n so we Deleted the record.');
return mail;

}

}

See Case IsClosed Trigger Bug?

This is not a bug. Currently the setting of this value is not done until the save which comes after the before trigger in the event timeline.

There are two workarounds available for you I believe:

1) Execute your logic in an after trigger. This occurs after the save and thus the value should be set. 2) Query CaseStatus with the value provided by the user for the status to determine if it is flagged as a closed status.

Which one you take would depend on whether you need to modify the object in any way since this is allowed in before triggers but not in after triggers.

Sounds like the easiest approach may be to use an after trigger instead.
