Error: 442 Connection Dropped During Transmission

What Is Causing This Error?

SMTP error 442 is a server response that indicates a temporal failure when sending emails through your site.

This error can occur due to a variety of reasons. The most common cause of this error is network issues between the SMTP server and the recipient’s email server.

In some cases, it could originate from the SMTP server you configured. Some SMTP service providers require account verification before you can start sending emails. If your account is unverified, you’ll likely encounter this error.

Resolving the Error – Solution

Since this error is often a temporary network issue, retrying after a while should resolve the error on your site. We also recommend checking your SMTP server settings to ensure it’s properly configured.

However, if you’re using AuthSMTP as your email service provider, this error could occur if your account hasn’t been verified. In such a scenario, you’ll need to contact their team to help verify your account.

Alternatively, you could switch to an API-based email service provider like SendLayer. Using SendLayer ensures emails from your site get delivered and prevents you from encountering occasional network issues.

That’s it! Now you know how to troubleshoot and fix the SMTP error 442 issue.
