If you own a digital store powered by Easy Digital Downloads (and not only) you might find the following plugins useful. Do not take my word for it, please, test and check their compatibility with your website first. Also, remember, the less plugins you have active, the better your website performance is. So try to keep only the essential/most useful ones and leave your dashboard nice & clean as much as possible.
Coming Soon Page & Maintenance Mode by SeedProd (FREE)
Work on your site while visitors see a "Coming Soon"; or "Maintenance Mode"; page. As an admin you will still be able to see your website.
Post Types Reorder (FREE)
Reorder your downloads without modifying the date. A simple drag & drop AJAX interface and your products will be displayed in the order you wish. A must have plugin.
MailPoet Newsletters (FREE)
This plugin simply works. It helps you add a subscribe form wherever you wish in your website, gathers e-mail addresses from your visitors if they choose to submit; then you can easily send newsletters post notifications or autoresponders from WordPress dashboard.
Digital Paybox (PREMIUM - $22.00)
Outside Easy Digital Downloads plugin, you can use this plugin for sharing freebies and making a few bucks maybe. Let people decide if they want to pay your download and what it’s worth. You can set up the "Pay what you want"; system with this plugin.
A big no - the lack of adding an URL download file outside WordPress. The files are attached to Media Library which is not a good practice for larger or a big volume of items.
Also, the e-mail addresses aren’t stored in a way that you can send mass newsletters. Therefore, if the visitors decide that your product worths $0.00 and downloads it for free, you are left with nothing. No additional traffic, no newsletter sign ups, no money.
Opt-In Panda for WordPress (PREMIUM - $23.00)
Leave the annoying pop-ups aside and get more subscribers in an elegant way: ask the visitors to enter their email addresses (without refreshing the page) to unlock your content ( or a download file, an mp3 file, anything). Build large mailing lists on MailChimp, Aweber, GetReponse, MailPoet (and other). But, too many steps required until you can actually see the content. On the first test I coulnd’t actually see the content after subscription. So to me, the script failed. I am sure there is a good explanation but your visitors couldn’t care less.
Contact Form 7 (FREE)
Let visitors contact you through your website. Contact 7 Form supports Ajax-powered submitting and spam filtering. It is very flexible and you can customize the mail contents with simple markup. Not the most user friendly.
WP Retina 2x (FREE)
Image files required by the Retina (High DPI) devices are created and displayed to your visitors.
WP Code Highlight (FREE)
Useful if you are selling digital products that require syntax highlighting of source code snippets.
W3 Total Cache (FREE)
Improve user experience and page speed. Make sure you follow the W3 Total Cache Config documentation. Be careful, this is a very complex and powerful plugin which can save your day or ruin your day!
BJ Lazy Load (FREE)
Lazy load images, videos and iframes make your website load faster and saves bandwidth.
