First you need a trigger that will call the email functionality based on the scenarion

 Trigger 
trigger SendEmailNotification on Task (after insert) {

	Set<Id> idContactSet = new Set<Id>();
    EmailManager emailMgr = new EmailManager();
    
    for(Task task : trigger.new) {
        
        if(task.WhoId.getsobjectType != Schema.SObjectType.Contact) continue;
        
        if(task.Subject != 'specific') return
        
        idContactSet.add(task.WhoId);
    }
    
    if(idContactSet.isEmpty()) return;
    
    List<Contact> contactList = [SELECT Id, Email FROM Contact WHERE Id IN :idContactSet];
    
    for(Contact contact :contactList) {
        
        emailMgr.sendMail (contact.Email, task, '' );
    }
    
}

Here is the class to send an EmailManager 
public class {

    // Public method
    public void sendMail(String address, String subject, String body) {
        // Create an email message object
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        String[] toAddresses = new String[] {address};
        mail.setToAddresses(toAddresses);
        mail.setSubject(subject);
        mail.setPlainTextBody(body);
        // Pass this email message to the built-in sendEmail method 
        // of the Messaging class
        Messaging.SendEmailResult[] results = Messaging.sendEmail(
                                 new Messaging.SingleEmailMessage[] { mail });
        
        // Call a helper method to inspect the returned results
        inspectResults(results);
    }
    
    // Helper method
    private static Boolean inspectResults(Messaging.SendEmailResult[] results) {
        Boolean sendResult = true;
        
        // sendEmail returns an array of result objects.
        // Iterate through the list to inspect results. 
        // In this class, the methods send only one email, 
        // so we should have only one result.
        for (Messaging.SendEmailResult res : results) {
            if (res.isSuccess()) {
                System.debug('Email sent successfully');
            }
            else {
                sendResult = false;
                System.debug('The following errors occurred: ' + res.getErrors());                 
            }
        }
        
        return sendResult;
    }

}

I miss the classname for the Email class. Try this code and give me your update. 
public class EmailManager {

    // Public method
    public void sendMail(String address, String subject, String body) {
        // Create an email message object
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        String[] toAddresses = new String[] {address};
        mail.setToAddresses(toAddresses);
        mail.setSubject(subject);
        mail.setPlainTextBody(body);
        // Pass this email message to the built-in sendEmail method 
        // of the Messaging class
        Messaging.SendEmailResult[] results = Messaging.sendEmail(
                                 new Messaging.SingleEmailMessage[] { mail });
        
        // Call a helper method to inspect the returned results
        inspectResults(results);
    }
    
    // Helper method
    private static Boolean inspectResults(Messaging.SendEmailResult[] results) {
        Boolean sendResult = true;
        
        // sendEmail returns an array of result objects.
        // Iterate through the list to inspect results. 
        // In this class, the methods send only one email, 
        // so we should have only one result.
        for (Messaging.SendEmailResult res : results) {
            if (res.isSuccess()) {
                System.debug('Email sent successfully');
            }
            else {
                sendResult = false;
                System.debug('The following errors occurred: ' + res.getErrors());                 
            }
        }
        
        return sendResult;
    }

Use this 
trigger SendEmailNotification on Task (after insert) {

	Set<Id> idContactSet = new Set<Id>();
    EmailManager emailMgr = new EmailManager();
    
    for(Task task : trigger.new) {
        
        if(task.WhoId.getSObjectType() != Schema.Contact.SObjectType) continue;
        
        if(task.Subject != 'specific') return
        
        idContactSet.add(task.WhoId);
    }
    
    if(idContactSet.isEmpty()) return;
    
    List<Contact> contactList = [SELECT Id, Email FROM Contact WHERE Id IN :idContactSet];
    
    for(Contact contact :contactList) {
        
        emailMgr.sendMail (contact.Email, task, '' );
    }
    
}

That is just a string missed the single quote. Here is with correction
  
trigger SendEmailNotification on Task (after insert) {

	Set<Id> idContactSet = new Set<Id>();
    EmailManager emailMgr = new EmailManager();
    
    for(Task task : trigger.new) {
        
        if(task.WhoId.getSObjectType() != Schema.Contact.SObjectType) continue;
        
        if(task.Subject != 'specific') return
        
        idContactSet.add(task.WhoId);
    }
    
    if(idContactSet.isEmpty()) return;
    
    List<Contact> contactList = [SELECT Id, Email FROM Contact WHERE Id IN :idContactSet];
    
    for(Contact contact :contactList) {
        
        emailMgr.sendMail (contact.Email, 'Submitted form - Talk to an Expert', '' );
    }
