How Do I Find the Web SMTP Server?

When it comes to setting up email functionality on a website, one of the most important pieces of information you need is the SMTP server. The SMTP server is responsible for sending outgoing emails from your web application or website. In this tutorial, we will learn how to find the web SMTP server using different methods.

Method 1: Checking with Your Web Hosting Provider

If you have a hosting provider for your website, they usually provide an SMTP server for you to use. Most hosting providers have documentation or support articles that outline the necessary information for setting up email services.

To find the SMTP server provided by your hosting provider:

  1. Login to your hosting account control panel.
  2. Look for the email settings section or similar.
  3. Navigate to the section that provides SMTP server details.
  4. Note down the SMTP server address and any required authentication credentials like username and password.

Method 2: Performing DNS Lookup

If you don’t have access to your hosting provider’s documentation or if you are managing your own servers, you can perform a DNS lookup to find the SMTP server associated with your domain name. Here’s how:

  1. Open a command prompt (Windows) or terminal (macOS/Linux).
  2. Type ‘nslookup -q=mx’ (replace ‘’ with your actual domain name).
  3. Note down the MX record(s) returned by the command.
  4. Use the SMTP server address provided in the MX record(s) as your web SMTP server.

Method 3: Contacting Your IT Department or System Administrator

If you are part of an organization or have an IT department managing your website, they should be able to provide you with the necessary information about your web SMTP server. Reach out to your IT department or system administrator and ask for the SMTP server details.

Remember to provide them with relevant information such as:

  • Your domain name
  • The purpose of using the SMTP server (e.g., sending transactional emails, newsletters, etc.)

Method 4: Using Third-Party Email Service Providers

If you don’t want to deal with setting up and managing your own SMTP server, using a third-party email service provider can be a great alternative. These providers offer easy integration options and take care of the email infrastructure for you.

Some popular third-party email service providers include:

  • SendGrid
  • Mailgun
  • Amazon SES (Simple Email Service)
  • Mandrill

To use a third-party email service provider:

  1. Create an account with the provider of your choice.
  2. Follow their documentation or guides on how to integrate their services with your website.
  3. Note down any required API keys or SMTP server addresses provided by the provider.

These third-party services often provide easy-to-use APIs and libraries for various programming languages, making integration a breeze.


Finding the web SMTP server is essential for setting up email functionality on your website. Whether you check with your hosting provider, perform a DNS lookup, contact your IT department, or use a third-party email service provider, there are multiple methods to obtain the necessary information. Remember to keep any required authentication credentials and API keys secure to ensure safe and reliable email communication from your web application.
