Is it possible to send a email to muliple people at once

Is it possible to send a email to muliple people at once

I have to notify my customers that we cannot service them during the Christmas holiday period and we need to postpone service until a date in Janurary.

Is it possible to send a templated email to multiple customers at once?

The current flow is to
  1. open the contact,
  2. add new ticket,
  3. choose template,
  4. replace the contact name because the template removes the contact name 
  5. send as email
  6. deselect the "Add Ticket Id to email's subject" box
  7. submit and send
  8. then manually close the ticket
I need to do this for around 100 customers.

Is there any way I can do this in bulk?
