MailChimp List Subscribe Form

The MailChimp plugin allows you to quickly and easily add a signup form for your MailChimp list.

Developer Mode

You can enable "Devleoper Mode" by adding the following line to your wp-config.php file just above the "That's all, stope editing!" line.

define('MAILCHIMP_DEV_MODE', true);

This will enable the MailChimp List Subscribe plugin to operate without the need to connect an external MailChimp Account, and will provide a subscription form widget that will not actually submit anywhere.

This will allow you to style and configure the widget in non-production environments that are not publicly accessible.

For more Developer Mode customization options see the following article:



If you are upgrading to version 1.2.1 and you used the widget in your sidebar previously, all you need to do is drag the MailChimp Widget back into the sidebar, visit the MailChimp settings page (which will have maintained your prior settings), click the "Update List" button, and you're done!

If your language is not listed above, feel free to create a translation. Here are the basic steps:

  1. Copy "mailchimp_i18n-en_US.po" to "mailchimp_i18n-LANG_COUNTRY.po" - fill in LANG and COUNTRY with whatever you use for WPLANG in wp-config.php
  2. Grab a transalation editor. POedit works for us
  3. Translate each line - if you need some context, just open up mailchimp.php and search for the line number or text
  4. Fork the repository on github
  5. Clone the develop branch
  6. Add the appropriately named files to the /po/ directory and edit the /readme.txt to include how you'd like to be attributed
  7. Make a pull request
