Same here. Do you think this data is from Email Apps/Clients rather than the addresses? iPhones are extremely popular and so I can imagine loads of people open their mail on their phones. But I have a hard time seeing more users being on Apple mail adresses compared to the huge widespread gmail.com users.
Used to use Sync and I still prefer it in a lot of ways, but I can see the writing on the wall what with ljdawson not having reared his head for well over a year. That app will stop working when Lemmy 1.0 rolls out.
Switched over to Summit and I’m slowly getting used to it. Still missing some features and options and having some bugs, but overall it’s good and I think it will grow into being the best app for me in the future.
