How To Send Emails Using Your Python Discord Bot

Note:

You need an email and SMTP credentials.
Example (Gmail):

– SMTP Host: smtp.gmail.com
– Port: 587
– Email: [email protected]
– App Password: required if Gmail has 2FA enabled

You should place these values directly in your code.

1. Log In to Your Panel

---

2. Select the ‘Files’ Tab

---

3. Create Your Main Bot’s File

Create a new file called index.py then paste the following code.

What this code does:

• Creates a Discord bot that listens for commands. We use the discord.py library for this.
• The bot uses ! as its starting symbol (the command prefix).
• Adds a command:
  • !mail [email protected] Your message here
• When a user types the command, the bot will:
  • Separate the message: It easily grabs the first word after !mail as the email address to send to, and the rest of the text as the email body.
  • Build the Email: It uses a special Python tool (MIMEText) to package the message content into a standard email format, setting a subject and who the email is From and To.
  • Connect to the Email Server (like connecting to Gmail or Outlook):
    • It finds the email server using the saved details (SMTP_HOST, SMTP_PORT).
    • It quickly calls server.starttls() to turn on security (encryption) , so your login details are safe.
    • It then logs in using the bot owner’s email and password (SMTP_USER, SMTP_PASS).
  • Send the email to the address you typed.
  • Reply in Discord with one of two simple messages:
    • “Email sent to **<recipient>**!” if everything worked perfectly.
    • “Email failed. Error: **<error message>**” if there was a problem (like a wrong password or a typo in the recipient’s email).
  • Prevents Crashes: This is all done inside a special try...except block, which means if something goes wrong, the bot just sends the error message and keeps running instead of stopping completely.
• Uses Python’s built-in smtplib tool for all the work of talking to the email server.

    try:
        msg = MIMEText(text)
        msg["Subject"] = "Message from Discord Bot"
        msg["From"] = SMTP_USER
        msg["To"] = recipient

        server = smtplib.SMTP(SMTP_HOST, SMTP_PORT)
        server.starttls()
        server.login(SMTP_USER, SMTP_PASS)
        server.sendmail(SMTP_USER, recipient, msg.as_string())
        server.quit()

        await ctx.send(f"Email sent to **{recipient}**!")
    except Exception as e:
        await ctx.send(f"Email failed. Error: `{e}`")

bot.run("YOUR_DISCORD_BOT_TOKEN")
