Superfast Newsletters with Mailgun

Sending newsletters directly from your WordPress site may be an easy solution, but it runs into severe limitations when you have a large mailing list, say more than 1000 subscribers. I discussed that in my previous post.

Using Mailgun as your email delivery provider in combination with the Newsletter plugin is a great solution that avoids the deliverability issues associated with shared hosting.

The standard Mailgun add-on

The standard Mailgun add-on for Newsletter sends only one email at a time through the Mailgun API. With the “Turbo” option, you may be able to increase the speed by sending up to 10 requests at a time, if your installation supports that.

But that still means 10,000 API requests in order to send your newsletter to 10,000 subscribers. This puts a significant strain on your website. Just as importantly, it will take a long time before all your subscribers receive your newsletter.

Superfast Mailgun

Fortunately, Mailgun has a “Batch Send” API that allows you to send an email to up to 1,000 addresses in a single API call. For 25,000 subscribers, that’s 25 API calls instead of 25,000 calls. Quite a difference. It will take a lot less time to send out your newsletter.

The Superfast Mailgun add-on for the Newsletter plugin allows you to take full advantage of this capability and thus greatly speed up the delivery of your newsletters, so that all your subscribers receive your newsletter on time.

The free version of Superfast Mailgun is available from your WordPress dashboard and on wordpress.org. Once you install it, you can easily upgrade to the paid version which offers the full range of features.
