How to Send 100,000 Emails Weekly Without Encountering Delivery Issues
Sending large quantities of emails weekly can present significant challenges, particularly in ensuring their successful delivery. While DIY solutions are possible, they require considerable technical expertise and may ultimately prove impractical.
Outsourcing for Simplicity and Cost-Effectiveness
The most straightforward and cost-effective approach is to outsource email delivery to specialized companies. This eliminates the need for in-house infrastructure and the complexities associated with maintaining email deliverability.
DIY Considerations for Self-Hosting
If outsourcing is not feasible, consider the complexities involved in self-hosting an email sending system:
Infrastructure and Technical Requirements:
- Dedicated SMTP server with sufficient capacity to handle the volume
- Configurable SMTP wrapper to send emails efficiently
- Custom sender function to process and send emails
- Sufficient virtual memory to avoid PHP memory limits
Delivery Optimization:
- Shuffle email delivery to avoid server bans
- Establish proper PTR, SPF, DKIM records
- Handle remote server timeouts and other network issues
Content and Compliance:
- Create non-spammy content that stands out from actual spam emails
- Handle invalid email addresses and maintain a clean subscriber list
- Manage unsubscribes to prevent users from marking emails as spam
- Handle email bounces and rejects effectively
Legal Implications:
- Comply with federal, state, and local anti-spam regulations
- Consider the impact of sending emails to recipients in different countries
Additional Considerations:
- Handle the delays inherent in SMTP protocol
- Mitigate the risk of emails being flagged as spam
- Address issues related to various email clients, particularly Microsoft Outlook
Conclusion:
While it is technically possible to self-host an email delivery system for large volumes, the complexities and difficulties involved make it a challenging and potentially time-consuming endeavor. Outsourcing remains the most practical and cost-effective solution for ensuring successful and compliant email delivery.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
