When managing a WordPress site, effective email communication is important for engaging your audience and improving relationships. However, many site owners struggle with low email delivery rates, leading to frustration when messages end up in spam folders or go undelivered altogether.
Imagine the disappointment of sending out newsletters, updates, or important notifications only to find that they never arrive. This not only affects your engagement rates but can also damage your reputation and trust with your audience.
This is where SMTP service providers can help you. WordPress SMTP plugins can significantly improve your email delivery rates and reliability, ensuring that your messages arrive in inboxes rather than spam folders.
With a variety of options available, from free to premium services, you can select an SMTP solution that aligns with your specific needs and budget.
Let’s find out the best SMTP service providers in this blog.
What is SMTP?
SMTP stands for Simple Mail Transfer Protocol. It is a standard protocol used for sending emails across the internet. When you send an email, SMTP directs it from your email client to the receiving server.
This process involves several steps:
- Connection: Your client connects to an SMTP server.
- Transfer: The email is sent to the recipient’s server.
- Delivery: The recipient’s server stores the email until it is retrieved.
Using SMTP helps ensure that your emails are sent quickly and accurately to their destinations.
Why Use SMTP with WordPress?
Using SMTP with WordPress can significantly improve your email delivery rates. WordPress may use its host server to send emails, which may not always be reliable. Here’s why using SMTP is beneficial:
- Improved Delivery: SMTP servers are designed for email sending, reducing the chances of your emails going to spam.
- Tracking: Many SMTP services offer tracking features so you can monitor your email success rates.
- Authentication: SMTP providers often require email authentication, adding a layer of security to prevent unauthorized use.
Setting up an SMTP plugin in WordPress enables you to manage your emails more effectively and ensures they reach your audience successfully.
