Fix Email Sending Errors – Skip Invalid Emails for OpenCart 3.x

Fix Email Sending Errors – Skip Invalid Emails for OpenCart 3.x

Description

This extension prevents errors caused by marketing emails being sent to invalid or non-existent email addresses.
In some cases, OpenCart attempts to send messages to email addresses that contain typos or are no longer valid, resulting in mail delivery failures or broken sending processes.

One of the most common issues is the SMTP error:
"Error: RCPT TO not accepted from server!

Server response: 550 5.1.1 : Recipient address rejected: User unknown in local recipient table",

which stops the entire campaign if not handled.

With this module, such email addresses will be automatically skipped during bulk mail sending (Marketing → Mail), ensuring a more stable and successful email campaign by allowing the process to continue even if some emails are invalid.

Features

  • Skips invalid or non-existent email addresses during marketing mail sending

  • Prevents mailing errors and campaign interruptions
