Superfast Mailgun for the Newsletter plugin

The Superfast Mailgun add-on for the Newsletter plugin allows you to take full advantage of the Mailgun “Batch Send” API. This makes it possible to send a newsletter to up to 1,000 addresses in a single API call. For 10,000 subscribers, that’s 10 API calls instead of 10,000 calls. Quite a difference. It will take a lot less time to send out your newsletter.

• Sends newsletters to up to 1,200 subscribers per hour.
• Polls Mailgun for “bounces” and updates your mailing list accordingly.
• Support by email or through the forum on wordpress.org

Note: Filters 'newsletter_message_html', 'newsletter_message_text', 'newsletter_message_subject' and 'newsletter_message' are called only once per email, and receive a null $user parameter. This is because Mailgun takes care of replacing user-specific tags in the email. Note that the Newsletter plugin has deprecated filters 'newsletter_message_html', 'newsletter_message_text' and 'newsletter_message_subject' in favour of 'newsletter_message'.When they are removed, this addon will stop using them as well.

This add-on will only work if you have The Newsletter Plugin installed (version 7.8.0 or higher). To use the Superfast Mailgun add-on, just install it like any other plugin.
