Create a welcome email for newly added WordPress users

This is a welcome email plugin that needs to go into your plugins folder, create a file called something like welcome.php or welcome-email.php and paste the following code in to that file. The file then needs to be copied to your wp-content/plugins/ folder. Once uploaded login to your dashboard > plugins and look for the newly added plugin then activated it.

Now you will have more of a personalised message for your newly registered users. Changes can be made in the plugin to adapt the message you would like triggered.
