(Mail Delivery Subsystem) 检查接收者 email 是否能够接收？

Question

I'm trying to send important email to an organization. their email account is always full. thus, It never receives my email due to the following error.

title:
Mail Delivery Subsystem

from:
mailer-daemon@googlemail.com

message:
Your message could not be delivered to ******@gmail.com. Either his inbox is full or he's getting a lot of mail right now.

The email account that you tried to reach is over quota. Please direct the recipient to https://support.google.com/mail/?p=OverQuotaTemp

not exact but similar problem

The error is clear but I need to find some solution.

I need some service or app to check out if the target email "the receiver" is available to receive now or not.

I assume the receiver might empty some space someday, and then I can send my email again if I have sort of service like the up mentioned.

As Inte.net standard, this is an expected behaviour and there is no work around for this unless the organization is willing to let you access the API for their account, which won't likely be the scenario since it is like asking to share access to their Gmail account to check the content.

If you had the notification Message sent ( which appears at the bottom left after sending your email ) and you do not receive the Message not delivered email and it is safe to assume that your message has been delivered to their inbox.

What you can do on top of this is to enable the read receipt when you compose your message. This is the closest thing we can have of getting a notification from the recipient.

The way read receipt works is when they open your email they will have a prompt to notify you with the option to approve or not. If they approve it you will receive an email notification, otherwise, you won't.
