How many mails we can bcc at one time

The maximum number of recipients you can BCC (blind carbon copy) in an email varies depending on the email service provider, email client, and even the recipient's email server.

Here are some general guidelines:

Gmail:

• The maximum number of recipients you can BCC in a single email is 500.
• If you try to send an email with more than 500 recipients, Gmail will truncate the list and only send the email to the first 500 recipients.

Outlook:

• The maximum number of recipients you can BCC in a single email is 50.
• If you try to send an email with more than 50 recipients, Outlook will truncate the list and only send the email to the first 50 recipients.

Yahoo Mail:

• The maximum number of recipients you can BCC in a single email is 100.
• If you try to send an email with more than 100 recipients, Yahoo Mail will truncate the list and only send the email to the first 100 recipients.

Other email services:

• AOL Mail: 100 recipients
• Hotmail: 100 recipients
• iCloud Mail: 100 recipients
• ProtonMail: 100 recipients

Email clients:

• Mozilla Thunderbird: 100 recipients
• Microsoft Outlook (desktop app): 50 recipients
• Apple Mail: 100 recipients

Recipient's email server:

• Some email servers may have their own limits on the number of recipients you can BCC. For example, some corporate email servers may have a limit of 20-50 recipients.

It's important to note that sending large numbers of emails to multiple recipients can be considered spamming and may be blocked or flagged as spam by email providers. It's always a good idea to check with your email provider or email client for their specific limits and guidelines on BCCing.
