Try this:

 from flask import request, render_template, flash

 @app.route('/', methods=['GET', 'POST'])
 def index():
     if request.method == 'POST':
         email = request.values.get('EMAIL')
         con1 = sqlite3.connect("check10.db")
         cur = con1.cursor()
         data = cur.execute("SELECT EMAIL FROM register WHERE EMAIL = ? ", (email,))
         if data == email:
             return render_template('homepage.html')
         else:
             flash('Check Credentials ')
             return render_template('loginpage.html')
  return render_template("loginpage.html")

Try also to change the variable email like:

email = request.args.get('EMAIL')

You are getting error because of return render_template('loginpage.html', alert).

If you want to send some data from server to HTML page then you can refer to link.

If you want flash message 'check credentials' to the user then refer to this Link
