Apostrophe’s in Email Addresses

A rare but valid question

Yes, you can use an apostrophe (') in the local part of an email address (the part before the @). For example:

✅ o’connor@example.com

However, apostrophes in email addresses can sometimes cause issues with certain websites, forms, or systems that do not properly handle them. Some email providers may not allow them at all. If you’re experiencing problems using an email address with an apostrophe, consider using an alternative format, such as:

❌ o’connor@example.com → ✅ oconnor@example.com or o.connor@example.com

Email Providers That Allow Apostrophes:

• Gmail: Allows the use of apostrophes in email addresses.
• Outlook: Permits apostrophes in email addresses.
• Yahoo: Supports the inclusion of apostrophes in email addresses.

Email Providers That Disallow Apostrophes:

• iCloud: Does not allow apostrophes in email addresses.
• ProtonMail: Restricts the use of apostrophes in email addresses.

It’s important to note that while some providers permit apostrophes, using them can sometimes lead to issues with certain websites, forms, or systems that do not properly handle them. If you encounter problems, consider alternative formats such as replacing the apostrophe with a period or omitting it entirely.
