Invalid Email Address
- Shonal Singh
BUZ only. recognises standard email format, which means:
- A prefix that appears to the left of the @ symbol
- A domain that appears to the right of the @ symbol
- Letters (A-Z), numbers, underscore ( _ ), dashes ( - ) and periods ( . )
Most email service providers will NOT allow you to have special characters (other than the ones above) to prevent bounce back emails and/or the emails going to spam/junk mailbox. There are some email service providers that do allow some extra special characters such as apostrophe’s ( ' ), exclamation marks ( ! ) e.t.c. however it’s not recommended as these can cause issues when sending and receiving to mailboxes such as @outlook.com and @gmail.com.
