Reply content:
Advertising emails are not the same as spam, especially when sent to members in bulk. If the effect is good, it can not only achieve the purpose of widespread advertising, but also play the role of communicating with users and increasing user stickiness.As for how to prevent emails from being considered spam and achieve good results, there are the following points to note:
1. First and most importantly, the content of the email must be of high quality , if the form of the email is rough and the content is worthless, it will definitely not achieve the advertising effect, and may even be complained by users;
2. Secondly, it is technical guarantee. For example, you need to choose a high-reputation option. IP sending, ESP whitelist filing, sending frequency control, etc., these can all be achieved by choosing a good email sending service;
3. Finally, there are some email sending tips , which requires long-term exploration, such as surveys on user habits, surveys on the best time to send, etc.
Recently, Sohu launched SendCloud, which specializes in sending triggered emails (including registration activation emails, password retrieval emails, etc.). It will also send newsletter emails (no advertising emails) in the future. It is under internal testing. You can apply for trial~ Advertising emails are not equal to spam emails. Take NetEase mailboxes as an example. If you add AD, you can enter the advertising mailbox, but if you don't add AD, it will easily enter the spam mailbox. There will be a new email notification when entering the advertising mailbox, but there will be no new email notification when entering the spam mailbox.
To reduce the number of emails entering the spam mailbox, you need to start with the title and content of the email, avoid some commonly used words that violate spam rules, code design specifications, etc., understand the rules of the ISP for receiving emails, and follow their rules for delivery. Don't disregard their rules for the sake of your own quantity. Also include an unsubscribe link in the email content to make it more standard. Don't talk about sending it to members. I just want to send advertising emails. Let me give you some useful information! The main technology of the spam filtering system is the Bayesian algorithm. To prevent the emails you send from being judged as spam, please prepare more different email contents. Write neatly, don’t leave a website address or pictures, leave a landline number for your phone number, and leave it different each time. Let’s briefly talk about the principle. The Bayesian system analyzes your emails and proposes ten key contents. Some content is a plus and some is a minus. If there are too many deduction items, it will naturally become garbage. Of course, there are actually more techniques, such as contextual semantic analysis. Just send an email to avoid points deductions. Write the email in normal language. Don't imitate those people who sell invoices and write some strange characters. The system can't read your language and it's just garbage. Websites, pictures, and mobile phones are all minus points. Try not to. Any cheap and replaceable contact information is a minus. Such as qq, email, etc., please understand carefully! The filtering system is not a simple black and white list of keywords, nor will it directly judge it as junk just because you wrote the word "invoice". Don't believe in any tricks and don't be clever. Those tricks are all deceptive. Programmers who write filtering systems are no stupider than you! What unsubscribe link should be added? Still legal? specification? This is in China, with Chinese national conditions, who cares about that? Adding this is an insult to the programmer's intelligence. In any case, emails are ultimately meant for people to read, so how can a machine stop them? To deal with the Bayesian filtering system, please start from my thinking. I wish everyone a happy advertising! Know how to promote customer QQ

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
