I have a fastmail account and a gmail account. The former I use for more formal and sensitive communications and accounts, the latter for more frivolous things.

I have a fastmail account and a gmail account. The former I use for more formal and sensitive communications and accounts, the latter for more frivolous things. Most people I communicate regularly with have messages from me from both accounts, so if I lost one, I could carry on communications until I established a new alternative. All important subscriptions using one account for contact, I use the other for an alternate.
