●user@example.com●userexample.com
●first.last+tag@sub.domain.org●@nodomain.com
●admin123@company.io●user@@double.com

How it works

Matches a local part (letters, digits, dots, underscores, percent, plus, hyphen) followed by @ and a domain with at least one dot and a TLD of two or more letters. It rejects addresses without an @ sign, consecutive dots, or missing TLD. This pattern covers the vast majority of real-world email addresses without full RFC 5322 complexity.

Code Usage

JavaScript

const regex = /^[a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}$/;
regex.test("user@example.com"); // true

Python

import re
pattern = re.compile(r'^[a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}$')
bool(pattern.match("user@example.com"))  # True

Go

import "regexp"
r := regexp.MustCompile(`^[a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}$`)
r.MatchString("user@example.com") // true
