Labels are good, perhaps better than folders. But they’re not for everyone. In small numbers, labels are definitely better. But the implementation provides a flat perspective of my archive. I would need some 30 labels to replace my 43 IMAP folders. That’s a bit too much for a flat categorization. And with 1 GB of storage, it’s just going to get worse.
And I wish that Gmail provided more control over my from email address. I hide my real address behind a cloud of forwarders, but there is no way to hide when Gmail uses the real address on every outbound email. Maybe they think they have the answer to spam and I don’t need to hide my real address. But I’m not going to convert without being able to hide.
All in all a good effort. Not quite good enough to make me leave FastMail. But definitely good enough to become the archive for all my mailing lists.
