Dear all three email

You want to send an email to all three recipients. Here's an example of how you can do it:

Subject: [Insert subject line here]

Dear [Recipient 1], [Recipient 2], and [Recipient 3],

[Insert your message here]

Best regards, [Your Name]

This format is a common way to address multiple recipients in an email. You can replace the recipient names with the actual names of the people you want to send the email to.

If you want to make it more formal, you can use a more formal greeting such as:

Dear Sir/Madam,

or

Dear All,

Just make sure to adjust the tone and language according to the context and the relationship you have with the recipients.

Let me know if you need any further assistance!
