Email sending error

Sending emails from contact forms is a crucial part of many websites and applications, but sometimes these emails don’t get delivered, and an SMTP error occurs. An SMTP error can happen for several reasons, and in this article, we’ll look at the five most common causes of SMTP errors with contact forms and how to fix them.

So here is the First 5 Common issue of every contact form and how to fix that.

  1. Incorrect SMTP server settings: One of the most common causes of SMTP errors is incorrect SMTP server settings. Check your email service provider’s documentation to ensure you have entered the correct SMTP server settings, such as the server hostname, port number, and encryption type. You should also verify that the login credentials are correct, including the username and password. Make sure to check for any typos and that there are no spaces or extra characters in the settings.
  2. Firewall or network issues: SMTP traffic is sometimes blocked by firewalls or networks, which can cause SMTP errors. You can test if a firewall is causing the issue by temporarily disabling it, or try using a different network or device to see if that fixes the problem. If your SMTP traffic is being blocked, you can contact your IT department or network administrator for help.
  3. Email quota or limitations: Your email service provider may limit the number of emails that can be sent per day or per hour, or they may block emails from specific IP addresses. Check if there are any limits or restrictions in place, and if so, try sending the email again later or contact your email service provider to remove the restriction.
  4. Authentication issues: SMTP servers require authentication to verify that the sender is authorized to send the email. Check that your SMTP server settings include valid authentication details, such as a username and password. If you’re unsure, contact your email service provider for assistance.
  5. Code issues: Contact forms often rely on code libraries or plugins, and sometimes these can have bugs or errors that cause SMTP issues. Check the code that handles the email-sending functionality for any syntax errors, and ensure that you’re using the latest version of any plugins or libraries. If you find any issues, you can try fixing the code yourself or contact a developer for assistance.
