In my knowledge, among paid email services, only Runbox doesn't recycle email addresses. Fastmail, Posteo.de and mailbox.org recycle your address within a few months. I don't know what Mailfence's policy is on this. Are there any other paid and privacy focused services that do not recycle email addresses on their domains?
