This leads to common problems like contact form submissions never arriving, or customer notifications going straight to the spam folder. **Dibrother Simple SMTP** solves this problem permanently. It reconfigures the ` wp_mail()` function to send all emails through a professional SMTP provider of your choice. This authenticates your emails, dramatically improving deliverability and ensuring your important messages reach the inbox every time. **Key Features:** * **Reliable Email Delivery:** Send all WordPress emails through a trusted SMTP server. * **Easy to Configure:** A clean and simple settings page guides you through the setup in minutes. * **Secure:** Supports SSL and TLS encryption to protect your email content and credentials. * **Lightweight and Fast:** No bloated code or unnecessary features. It does one job and does it perfectly. * **Test Email Functionality:** Quickly send a test email to verify your configuration is working correctly. * **Universal Compatibility:** Works with any SMTP provider, including Gmail, SendGrid, Mailgun, Amazon SES, and your own private email server. **(Tiếng Việt)** **Email từ website WordPress của bạn có bị thất lạc hoặc rơi vào spam không?** Mặc định, WordPress sử dụng hàm `mail()` của PHP, một phương thức thường không đáng tin cậy và hay bị các máy chủ hosting giới hạn. Điều này dẫn đến các vấn đề phổ biến như không nhận được email từ form liên hệ, hoặc thông báo cho khách hàng bị chuyển thẳng vào hòm thư rác. **Dibrother Simple SMTP** giải quyết triệt để vấn đề này. Plugin sẽ cấu hình lại hàm `wp_mail()` để gửi tất cả email thông qua một nhà cung cấp dịch vụ SMTP chuyên nghiệp mà bạn chọn. Điều này giúp xác thực email của bạn, cải thiện đáng kể tỷ lệ gửi thành công và đảm bảo các thông điệp quan trọng luôn đến được hộp thư đến. ## Screenshots * [[ * The clean and simple settings page. ## Installation 1.

You can get your SMTP settings from your email provider (like Gmail, Outlook) or your transactional email service (like SendGrid, Mailgun, etc.). They will provide you with the Host, Port, Username, and Password. ### Can I use this with Gmail? Yes! For Gmail, you would typically use: * **SMTP Host:** `smtp.gmail.com` * ** SMTP Port:** `587` * **Encryption:** TLS * **Username:** Your full Gmail address( e.g., `your.name@gmail.com`) * **Password:** Your Gmail **App Password**. You need to generate an App Password in your Google Account security settings. Using your regular password will not work if you have 2-Factor Authentication enabled. ### Where can I get support?
