invalid_email: the address syntax is not valid

invalid reason: invalid_email

The address is not written as a valid email address.

What it means

The address failed the syntax check, so no DNS or SMTP check was needed. It cannot receive mail as written.

Why it happens

• Missing or doubled @ (jane.example.com, jane@@example.com).
• Spaces, commas or quotes copied from a spreadsheet (jane doe@example.com, jane@example.com,).
• A domain without a dot or ending with one (jane@example, jane@example.).
• Two dots in a row, or a dot at the start or end of the part before the @.

What to do

• Look at the address before deleting it: many syntax errors come from exporting a file (an extra comma, a space, two addresses in one cell) and are easy to fix.
• In a form, catch it on the page with a simple format check and ask the person to correct it.
