- • Number-based: Numeric-only usernames
- • Mixed: Combination of letters and numbers
Name-based example:
john.smith123@gmail.com
Plus Addressing Support
Enable plus addressing to create emails with tags like user+tag@domain.com. Perfect for testing email filtering, organization, and Gmail/Outlook plus addressing features.
Supported by Gmail, Outlook, and many email providers. All emails sent to user+tag@domain.com are delivered to user@domain.com, allowing you to filter and organize emails by tag.
Plus addressing example:
user+test@gmail.com
Username Length Control
Adjust username length from 4 to 20 characters. Shorter usernames (4-8 chars) are more common in real emails, while longer ones (12-20 chars) provide more variety for testing.
Special Characters & Numbers
Toggle Include Numbers to add digits (0-9) and Special Characters to include dots (.), underscores (_), or hyphens (-). These options make emails more realistic and varied.

- • Testing your own email systems and validation logic
