📧 How to Send Emails Like a Pro Using Termux and Python in 2025

Short Snippet: Learn how to send emails using Termux and Python with your Gmail SMTP. This easy guide explains app password setup, email scripting, and sending messages securely — all from your Android phone.

📬 Introduction

Did you know that you can send emails straight from your Android phone using Termux and Python? Whether you're into ethical hacking, automating work, or experimenting with cool projects, this guide helps you create a real email-sending tool using Gmail SMTP!

🧠 What is SMTP?

SMTP stands for Simple Mail Transfer Protocol. It’s how your emails are sent from one server to another over the internet.

It acts like a postman for emails.
Used by Gmail, Outlook, Yahoo, etc.
Allows apps or scripts to send emails securely.

🔐 How to Create a Gmail App Password

To send mail via Gmail SMTP securely, you need to create an app-specific password:

Go to account.google.com
Navigate to Security
Enable 2-Step Verification
After that, go to App Passwords
Select:
- App: Mail
- Device: Other (Termux/Python)
Click Generate
Copy the 16-digit password shown — this is your app password.

💡 This app password is safer than your Gmail password. You’ll use it only for your script.

📲 Setting Up Termux

Now let’s get Termux ready to send mail.

Step 1: Install Python and Update Termux

pkg update && pkg upgrade
pkg install python

Step 2: Create the Python Script

nano mail.py

Paste the following code:

import smtplib
from email.message import EmailMessage
import getpass

print("\n" + "="*50)
print("        MAIL by kumarsmagic.com")
print("="*50 + "\n")

smtp_server = input("SMTP server (e.g. smtp.gmail.com): ").strip()
smtp_port = int(input("SMTP port (e.g. 587): ").strip())
email_address = input("Your email address: ").strip()
password = getpass.getpass("Your app password: ")

to_email = input("\nRecipient email: ").strip()
subject = input("Subject: ").strip()
body = input("Message body: ").strip()

msg = EmailMessage()
msg['Subject'] = subject
msg['From'] = email_address
msg['To'] = to_email
msg.set_content(body + "\n\n-- Sent via kumarsmagic.com mailer")

try:
    with smtplib.SMTP(smtp_server, smtp_port) as smtp:
        smtp.starttls()
        smtp.login(email_address, password)
        smtp.send_message(msg)
    print("\n✅ Mail sent successfully!")
except Exception as e:
    print(f"\n❌ Failed to send email: {e}")

📤 Run Your Script

Now simply run the script using:

python mail.py

It will ask for the following inputs:

SMTP Server: smtp.gmail.com
Port: 587
Your Email
Your Gmail App Password
Recipient Email
Subject
Message Body

✅ If all goes well, your mail will be sent instantly!
