How to send multiple people the mail using UTL_SMTP - oracle

Question

I have been trying so hard but not able to implement
Any solution is great appreciated !!!
I am using APEX 20.x
I Built one form which as following content in it : textfiled , textarea , choosfile , button
FROM EMAIL : TextFiled1
SUBJECT : TextFiled2
NOTES : TextArea1
ATTACHMENT : choosefile1
SUBMIT
Database records in table : EMPLOYEE
ID,NAME,AGE,EMAIL,STATUS
11,ALICE,12,abc#protonmail.com,Y
32,BOB,32,acd#protonmail.com,N
45,RAY,22,xyz#protonmail.com,Y
36,TIN,24,tin#protonmail.com,Y
My code :
CREATE OR REPLACE PROCEDURE send_mail (p_to VARCHAR2,
p_from IN VARCHAR2,
p_subject IN VARCHAR2,
p_message IN VARCHAR2,
p_attachment IN BLOB,
p_notes IN CLOB,
p_smtp_host IN VARCHAR2,
p_smtp_port IN NUMBER DEFAULT 25)
AS
l_mail_conn UTL_SMTP.connection;
BEGIN
l_mail_conn := UTL_SMTP.open_connection(p_smtp_host, p_smtp_port);
UTL_SMTP.helo(l_mail_conn, p_smtp_host);
UTL_SMTP.mail(l_mail_conn, p_from);
UTL_SMTP.rcpt(l_mail_conn, p_to);
UTL_SMTP.open_data(l_mail_conn);
UTL_SMTP.write_data(l_mail_conn, 'Date: ' || TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS') || UTL_TCP.crlf);
UTL_SMTP.write_data(l_mail_conn, 'To: ' || p_to || UTL_TCP.crlf);
UTL_SMTP.write_data(l_mail_conn, 'From: ' || p_from || UTL_TCP.crlf);
UTL_SMTP.write_data(l_mail_conn, 'Subject: ' || p_subject || UTL_TCP.crlf);
UTL_SMTP.write_data(l_mail_conn, 'Reply-To: ' || p_from || UTL_TCP.crlf || UTL_TCP.crlf);
UTL_SMTP.write_data(l_mail_conn, p_message || UTL_TCP.crlf || UTL_TCP.crlf);
UTL_SMTP.close_data(l_mail_conn);
UTL_SMTP.quit(l_mail_conn);
END;

What I am trying to implement :
I need to iterate through my table EMPLOYEE and read one by one email id's and send email to them.
Need to write some for loop to iterate the employee table ? and shoot mail to them with details entered in components along with that if attachment if choosen [optional] : SUBJECT , NOTES , ATTACHMENT
I have 700+ email ids
Need to send all of them same details over their mail one by one reading from table EMPLOYEE
