How to reference certified mail in a letter

When referencing certified mail in a letter, you should include the following information:

1. The certified mail number: This is a unique number assigned to the certified mail piece by the postal service. It can be found on the certified mail receipt and on the certified mail label.
2. The date of mailing: This is the date the certified mail piece was mailed.
3. The name and address of the recipient: This is the name and address of the person or organization to whom the certified mail piece was sent.

Here is an example of how you might reference certified mail in a letter:

"Dear [Recipient],

I am writing to confirm that I mailed a certified letter to you on [Date of Mailing] with the certified mail number [Certified Mail Number]. The letter was sent to [Recipient's Name] at [Recipient's Address].

Sincerely, [Your Name]"

Alternatively, you can also use a more formal tone and include the following language:

"This letter is being sent to you via certified mail, with a return receipt requested. The certified mail number is [Certified Mail Number] and the date of mailing is [Date of Mailing]. Please sign and return the return receipt to confirm receipt of the letter."

It's also a good idea to keep a copy of the certified mail receipt and the certified mail label for your records, in case you need to prove that you mailed the letter.
