The secret of mass mailing technology

Believe that a lot of webmaster are lazy, I believe many owners have used to promote the site of mass mail, but also believe that most of the webmaster think that if the message sent out and into the inbox effect is very obvious. So how does the mail go? How do I get into the inbox? How do you think your email is spam? I will talk about this problem based on my one-month experience in mail-sending.

Let's start with two ways to send mail. One is the DNS speedpost, either through an SMTP server or a relay server. DNS SpeedPost is to use the Internet DNS server directly sent out mail, this does not go through the SMTP server, that is, not through the smtp,126.com,smtp.tom.com these, so the letter name can be arbitrarily taken, the sender's mailbox can also casually, so you can be anonymous. So that we can say, so we can use such a DNS server has been hair all the time ah. Wrong。 For example, we send to QQ or send to 126, their servers can be judged from the DNS sent the letter. Foxmail is the function of the DNS SpeedPost, is only a single send, you send it, sent to the QQ mailbox, is into the dustbin, and then send a few more, directly to receive. Currently on the market many bulk mail or use of this technology, I would say that the DNS group has been dying. The success rate is very low. Software is a bluff.

Then only through the SMTP server to send. There are many techniques and experiences in this process. Sometimes back to the letter how I do not know why, and then studied for one months on the general groping out, today to share my experience to everyone.

We must first understand the process of the letter. POP3 is the recipient, SMTP is the letter. I'll draw a picture for you to see. For example, we use Tom's mailbox to send a letter to QQ. Then it is:

The IP and form of the message sent (either on the Web or on the client side)--pop3.tom.com--smtp.tom.com--pop3.qq.com

We can understand this picture clearly. Our mail content, IP address, the form of the letter is by our credit relay server POP3 judgment. Finally to send to which mailbox, he judged is the relay server and our mail content.

After a lot of my test (we sent the target is QQ mailbox)

The POP3 of the 1.tom mailbox does not judge the message sent. All accepted. But next time to send QQ. QQ will make judgments. The basis of the judgement is the content of the mail, so to modify the content of the message is not advertising, but the same frequency, such as a 1W send, will be QQ judge as spam. So that the letter back to Tom's mailbox.

2.foxmail Mailbox is Tencent's product. The technology is the same as QQ mailbox, the first to determine the routing of IP and content, content to do the best (not be judged as spam) IP fixed, about 400 blocked. Directly to Foxmail's POP3. So the way to deal with this is to switch IP.

3. Own peanut shell dynamic Domain name analysis to build the local SMTP and POP3 server, our own POP3 and SMTP, there is no verification, so all can be sent out, and then sent to QQ, for this inexplicable SMTP server, QQ judge the basis of the first is the frequency limit, Our SMTP is too frequent to the QQ mail server to send mail, resulting in a return. If you still send it frequently, your email address will be blocked, and frequently, your SMTP address should be blocked.

4. Other mailboxes.

Sina's POP3 to judge the client, if it is not OE or foxmail class of well-known software or in the web of the Sina mailbox sent, directly to the POP3 server.

Gmail sent to the QQ mailbox, received.

Send with Sougou mailbox. Not receive.

e-Mail can only be sent to its users when the client is set up. Failed。

QQ after 10 minutes after receiving a letter from Gmail.

Smtp.yeah.net test failed.

Sina sent successfully, note that after the registration of the mailbox to open POP3 and SMTP in the account settings. But QQ did not receive. Can be sent out in the mailbox. Not be sent out in the software. It is estimated that Sina has made a judgment on the sending end.

3126.com sent successfully. But I didn't get it. In the mailbox also can not send QQ mailbox. There is no hope at all.

Smtp.ymail.cn sent successfully. But in the trash.

ymail.com send failed.

There is a lot of learning and complexity in this midst. Sometimes do not randomly send a letter, or QQ notice your mailbox or your SMTP, the next hair on over. Maybe I've said so much, and a lot of people will not understand. I still have a lot of things to say, for fear that everyone will not accept it. Mail mass is a troublesome thing. From the Internet this day junk mail is a hit target. At present, the end is also basically mature, spam is increasingly difficult to send. TX's anti-spam is the best to do. I don't have a good way to make sure that I'm sending all my inbox.

Then everyone is concerned about how to send into the QQ mailbox. This article discusses the ultimate goal of my test is QQ mailbox, because the QQ mailbox is the most difficult to challenge, of course, other mailboxes will be relatively simple.

That's what I'm doing right now. Tom's mailbox is the worst. Send the basic message he does not filter to the QQ. So I used Tom's hair, but that's why. Tom's mailbox to QQ hair is into the dustbin. Don't believe you try. But go into the dustbin and go into the rubbish bin. I want to tell you want to give QQ hair some people are into the dustbin can not enter many seals, but I can enter tens of thousands of a day. It's from Tom's mailbox.

With Vmailsener This software, I apply for 25 Tom mailboxes, he will rotate the hair. Basically I will send 6000 letters at a time. These 6000 are all can send out, but all in the QQ trash box. It's okay. My heart is not greedy, can enter the rubbish bin on it. Because sooner or later one day the owner of the mailbox will see. 6000 is my own custom. No more. Once I have been downloaded 1W, 1W after the letter to all the direct return of Tom. This 6000 is finished, then wait 2 hours to send 6000 again, so hair 10 times a day. You can send out 6W. Don't be greedy.

This is the day, of course, evening, because I was in the dormitory with a router to surf the internet, and so on the evening students sleep after I use ADSL internet, you can switch IP, switch IP do. Because we are going to use the Foxmail mailbox hair. Foxmail is very strict, will judge your IP, so we need to switch IP. So in the daytime with Tom (because Tom is stupid, Tom will not be a letter to you to do very strict judgment), a Foxmail mailbox to QQ letter, 20 consecutive letters can not be issued. 20 a foxmail, the continuous hair 400 or so can not be. So plus switching IP, you can achieve more. I use 20 foxmail, with Vmailsender, plus an ADSL redial software. Set the appropriate number of seconds. Send 2000 letters. Actually can be sent. But I'm satisfied. Because an ADSL total can switch these 255 IP. Send these 2000 times some IP has been temporarily blocked, and some mailboxes have been temporarily blocked. I'll keep it for the next night. Is this 2000? I can also build my own SMTP server. With what? Use a Mmail server. The official price is probably more than 4,000. The trial version can be tested for 30 days and set up 20 accounts. Of course I have cracked version. We build a server ourselves. We do not judge this end, sent to QQ, every night I also send 2000 letters.

So every day I guarantee 4000 into the QQ Inbox, 6W sealed into the QQ garbage bin. We all know that QQ Mail letter will be on the desktop in the lower right corner to remind. QQ mailbox quality is very high. Every day these 4000, whether it is to do a chat room CPA registration or is currently very hot SNS invitation, are very optimistic, and every day 6W of spam will be the owner of the Mail constantly unearthed.

Say the end word. Online now popular mail mass software I have tried the basic. Every satisfaction. Mass mailing is a combination of various software. The effect I'm combining right now is what I'm talking about. I have a friend also said the most important is the method, not the software, he said he used 5 software to ensure that 95% letters to the QQ Inbox, I did not ask him, I do not believe. Because after one months of research, according to my drawing of the theory of the diagram I really do not have any better way.

About the mail mentioned in this article, some friends want to discuss with me can add my QQ9353439. Besides, I just took him to do technical research, after one months of research has never sent a spam mail, I hope you do not scold me.

Finally, spent one night writing this technical article, also soft. I've created a new resource site with a variety of promotional software I've tried out. Just built, the software is not much, and then slowly add on.
