Some of my emails drop into Spam Folder at recipient.
When sending email the receiving server will apply certain rules and conditions to attempt to pick out what messages appear to be spam. These rules and conditions change depending on how the receiving server is configured.
The email you sent may have contained certain links, images keywords or any content that the server receiving it may have falsely flagged as spam. Unfortunately we are unable to make any changes to assist in delivering it to the inbox. This is controlled by the recipients server configuration. We recommend that you have the recipient add your domain or email to their safe senders list to prevent this from happening in the future.
