Quick tutorial on how to send emails using Python and smtplib.
Sendgrid offers 100 free outbound emails per day, sign up with them via sendgrid.com/free, create a API Key and save your credentials in a safe place.
You first need to verify your account by sending a mail using their API, but it's step by step so won't take more than 2 minutes to complete.
Once the verification is completed, our Python Code:
import smtplib from email.MIMEMultipart import MIMEMultipart from email.MIMEText import MIMEText mail_from = 'Ruan Bekker <email@example.com>' mail_to = 'Ruan Bekker <firstname.lastname@example.org>' msg = MIMEMultipart() msg['From'] = mail_from msg['To'] = mail_to msg['Subject'] = 'Sending mails with Python' mail_body = """ Hey, This is a test. Regards,\nRuan """ msg.attach(MIMEText(mail_body)) try: server = smtplib.SMTP_SSL('smtp.sendgrid.net', 465) server.ehlo() server.login('apikey', 'your-api-key') server.sendmail(mail_from, mail_to, msg.as_string()) server.close() print("mail sent") except: print("issue")
When I ran the code, I received the mail, and when you inspect the headers you can see that the mail came via sendgrid:
Received: from xx.xx.s2shared.sendgrid.net (xx.xx.s2shared.sendgrid.net. [xx.xx.xx.xx])
