Technical Details

  1. MailPress sends one mail for each recipient, so before sending thousands of mails in one pass, make sure your webserver and mailserver can afford it !
    (see also Batch_send add-on)
  2. Requires php7
  3. php function proc_open must be available
  4. php extensions simplexml and intl must be available


  1. Before any installation, make sure you have a smtp server available (supports smtp (default) or sendmail).
  2. Have all informations to access to this server at hand.
  3. The installation process is like any other plugin.
  4. Once activated, go to “Settings > MailPress”, fill and save the settings for each tab (General, (Connection to your mail server), Test, …
  5. Once everything is set, use the Test tab in “Settings > MailPress” to validate your settings (your first mail with MailPress)
  6. You can also install the MailPress widget on your front page : “Appearance > Widgets”.
  7. Just browse the different MailPress admin screens, read the help in the help tab for each screen.
  8. Now that you are familiar with this plugin, you can visit “Plugins > MailPress Add-ons” to add options to your plugin (may be you already did it to activate sendmail).
  9. I wisely recommand to activate add-ons one by one, and see what are the changes in the MailPress settings admin panel, in the help, etc …

“Fatal Error” X|

When I try to activate the plugin a popup appears saying it can't be activated. Actually the best newsletter plugins are TheNewsletterPlugin and Mailpoet. Hope to see Mailpress join the crew soon! Teo (3 stars of encouragement)


Es el sistema que he venido utilizando en los últimos años. Es un sistema muy potente y gratuito pero resulta difícil de configurar, tiene pocas opciones para adaptar el tema (y no es fácil) y lo peor, cada vez que actualizas a una nueva versión tienes que hacerlo manualmente porque se desconfigura todo! Tiene un foro de ayuda que el autor atiende amablemente, pero si tienes un problema complicado te tienes que apañar como puedas. No lo recomiendo.
