title: How long does a page alive while sending multiple mails simultaneously?
body: <p>I have a CSV file which contains for example 50 different mails in 50 rows. When I import the file, I need to read that mails one by one and store mails in the database and then send some contents to every each of them.
  I'll implement that functionality with php mail function.</p>
  
  <p>The problem is for sending that multiple mails, would it exceed the maximum loading time? Would it crash the page? If so, are there any other ways to achieve my requirements? </p>
  
  <p>Thanks.</p>
