Requirements:

• free
• will not delete my account due to inactivity
• privacy focused (doesn’t have to be crazy private, just decent)
• doesn’t require my phone number
• doesn’t require an invitation (like riseup mail)

Additionally it would be cool if it allowed me to have few email addresses in 1 account (skiff lets you have 4 addresses you can send emails from, but they are shutting down their service).
