Delayed Email Plugin

WordPress plugin WP Delayed Mail lets you send an email at a later time. Why would you need to do this? Well if you’re running an online store you may come across a need where you would like to follow up with a customer after a specific period of time such as after a purchase or after registration.

This plugin allows you to add code to be send an email at a later time

To use it, pass the same arguments you would to wp_mail() instead to wp_delayed_mail(), except make the first argument the time at which you want the email to be sent, in a Unix timestamp.

For example, to send an email immediately in WordPress, you would usually do the following:

wp_mail(
   'recipient@example.com',
   'Subject',
   'Hi, there!'
);

To send it instead four hours later using wp_delayed_mail

wp_delayed_mail(
   time() + ( 60 * 60 * 4 ),
   'recipient@example.com',
   'My Subject',
   'Hello!  How are you?'
);
