How many mails are there on my number

I'm happy to help! However, I need a bit more information from you. Could you please provide me with the following details:

1. What type of phone number are you referring to (e.g. mobile, landline, VoIP)?
2. Which email service provider or platform do you use (e.g. Gmail, Outlook, Yahoo)?

Once I have this information, I can try to help you find out how many unread emails you have on your account.
