Error if email address does not exist

[shahriyasojol114]

As mentioned above, if you are getting an error about a non-existent email address, this can be resolved by checking that there are no errors in the username or domain name.

Please check that the format of the characters and numbers in the user name or domain name are correct, and if there is a way to contact the person other than email, please ask them for the correct address. You can also display a message on My Page indicating that there is a delivery error.

If the problem persists, please check to see if your email address has been deleted.

If an incorrect address exists, the email will be sent to a france mobile database different address than the intended recipient. In some cases, this could lead to the leakage of personal information, so be sure to check the recipient address carefully before sending.

When distributing email newsletters, etc., operational measures such as obtaining recipient addresses through double opt-in are also necessary.

Error message due to spam detection
The criteria for determining whether an email is spam differs depending on each spam filter, and are not publicly disclosed, so it is difficult to create email content that will not be detected as spam. (It is generally said that TEXT emails are less likely to be detected as spam than HTML emails, and that emails that do not contain URLs or advertising content are less likely to be detected as spam.)

The most reliable way to prevent your email from being marked as spam is to have the recipient set up their email so that emails with specific "From" addresses are not marked as spam.
