How to clean your list?

[mdsojolh444]

There are two types of list cleaning: "methods you can do right now" and "methods you should do regularly." We will explain each one.

List cleaning you can do right now
The most reliable thing to do right now is to delete any email addresses that have bounced back. These bounce back emails will be returned as error emails, so you can immediately tell which email addresses were not delivered to. If there is a high probability that the email address is valid, such as an address on a business card you received from the other person, you can delete it if it has bounced back multiple times.

Another thing you should do is delete the "contact address." Contact india whatsapp number data addresses are used by many companies as the address of their main contact point, as shown below.

These email addresses can easily be obtained by third parties, and can even be inferred and arbitrarily generated, so if there are many of these addresses included, it may be considered spam. If it is an email address received from the other party, there is no problem, but if there is an unknown contact address, it is safer to delete it.

Regular list cleaning
Next, as part of your regular maintenance, you should also delete any "provider emails" or "carrier emails" that you may want to clean your list from. Provider emails are email addresses issued by major providers such as "ocn" and "plala," and many people used them for work in the past, but now most people use their company email addresses or free email addresses.

Carrier email is an email address with a domain such as "docomo.ne.jp" or "ezweb.ne.jp" issued by a mobile carrier.

These email addresses are likely to be old, and even if they were delivered, it is quite possible that the recipient did not see them. Since this leads to an increase in the number of unnecessary deliveries, we recommend deleting them as part of list cleaning.
