Do you ever create sites and need an email address for it but it’s not something you plan on using often or a project you’re not going to pursue yet? Back in the good old days, you could slap Gmail on that domain for free, but now it’s $5 per user per month and that adds up. Zoho has a free mail plan which is super nice. It’s what I use for StartupResources.io. It’s free up to ten users for the basic plan, and their paid plans are affordable if you need to scale up. It has a nice iPhone app as well.
