Warning for folks using or considering using the Spark client. I downloaded and set up the Spark email client back in 2019, thinking I'd enter my IMAP credentials for local email usage.

My fault for not reading how it works, including storing my email credentials (username and password) on their servers, and storing my emails on their servers to send push notifications.

What's worse is that I've got almost 1000 email aliases ([e-mail]) set up over the years to filter email and block companies that send spam or get hacked. And I started to receive marketing email from Readdle (company behind Spark) to my main email address (which I would never give out to any company).

Tl;dr: they store your email credentials and send marketing emails to your main address.
