Full disclosure: I am an affiliate through these products and services. But, I am so because I use these products on a daily basis and highly recommend them.
Hosting and whatnot
I’ve had my fair share of hosts over the years, I’ve even been an affiliate for quite a few. I can say with confidence that Flywheel is hands down the best. Hosting starts at $15 per site, or you can buy in bulk (like I do). It’ll be the best $15 you’ve ever spent on the internet. It’s managed hosting, and it’s awesome.
Gravity forms is the best contact form plugin out there, period. You can buy it once, but to get updates and continued support you’ll need to renew yearly.
WP Email Capture is a plugin that, well, captures emails. It loads all of them into your WordPress site and then you can export them from there for any type of database or any bulk email service, such as MailChimp.
Easy Digital Downloads is an ecommerce plugin specifically for digital goods. The main plugin is free and then any add ons you need are a few bucks. If you’re selling digital goods, you need EDD. I have a few themes specifically for EDD available over at ThemeForest.
Cart66 is another ecommerce plugin that I love. It can also do digital goods and subscriptions, but where it shines is physical products. I also have a few themes specifically for Cart66 available over at ThemeForest.
