In the process of EDM marketing, many customers mentioned that the success rate of email delivery is too low. This article will analyze the reasons for this.

I. problems of our own side

The wrong address of the recipient of the mail is the main reason for the bounce.

The recipient's email address is generally in name@domain.com format, where name is the recipient's mailbox name and domain.com is the domain name of the recipient's mailbox service provider. Incorrectly filling in either of these two parts may result in a letter return.

You can follow these steps to check the recipient address you filled in:

1. Check whether the domain name contains characters that are not allowed to be used, such as /, *?;, etc. These characters may be the wrong characters that you inadvertently enter when you hit the keyboard.

2. Please check whether the domain name format is legal. Generally speaking, the domain name format is domain.com.

3. Please check whether there are spaces that should not appear in the recipient address you entered

4. Check the recipient address you entered again to see if there are some confusing characters in the address that cause you to type incorrectly. For example:

Capital O and the number 0

Lowercase l and the number 1

Lowercase g and the number 9

Lowercase l and uppercase I.

After the above check, you are still unable to find the error reason of the recipient's address, please contact the other party to make sure that the email address is correct.

Second, the question of the other party

The recipient's mailbox or the recipient's mail service provider may also prevent your mail from being delivered. Here are some of the most common reasons:

1. The recipient's mailbox is full or the remaining space is unable to accommodate the message you sent.

2. The recipient rejected your email

3. The recipient's mail service provider has a limit on the frequency of receiving mail.

4. The recipient's mail service provider identifies your mail as spam.

5. The recipient's mail service provider has blocked your email address.

The recipient's mailbox is full or the remaining space is unable to accommodate the message you sent.

If the recipient's mailbox is already full, or if the remaining space in his mailbox is smaller than yours, the message will not be delivered successfully.

The recipient rejected your email.

The recipient may have created some message filtering rules that caused your message to be rejected. For example, add you to the blacklist.

The recipient's mail service provider has a limit on the frequency of receiving mail.

In order to prevent the infringement of spam, many mail service providers have imposed restrictions on the frequency of mail acceptance. If you send a message to a recipient too frequently, or send a large number of messages to a user to which a mail service provider belongs, the mail service provider may temporarily refuse to accept your message, causing the message to be returned.

If you send emails to the same mail service operator too frequently, you can try to slow down your sending speed and see if you can solve the problem.

The recipient's mail service provider classifies your mail as spam.

Your email may contain keywords that appear to be advertised, causing the recipient's email service provider to reject your email as spam.

The recipient's mail service provider blocked your email address.

The recipient's mailbox service may have blacklisted your email address and refused to receive any mail you sent.

III. Network problems

Unstable network communication quality or too slow network speed may also lead to mail can not be sent successfully, resulting in bounce.

QQ Mail's mail server may be temporarily unable to contact the recipient's mail server, or there may be an error or disconnection during the contact process, resulting in the recipient being unable to receive your email.
