Email management - sending a standard email to individuals on list

Take a standard text only email and send it individually to a list of email addresses with personalised first name. This needs to be sent individually from a company email address to be set up and not through an email marketing platform or tool. The work scope involves managing provide lists, simple cut and paste of a standard email text and subject header provided and then personalise the first name only before sending. Target is to send 350 emails per day. Project is 8 hours per day, five days per week for a period of one month.
