Question: I want to create some reddit accounts. (which email provider)

I want to create some reddit accounts (and, in the future, I want to buy a few ones), My goa is to create around 10 accounts manually and using free proxies (I want a cheap solution).

However, I have some doubts about the email. What is the best email server for this? Or, is it better to use your own email server? I have some domain names but I'm not sure if it's worth to do that.
