Amazing)) I had more than 999+ unread emails. I love Gmail, but it was a bit messy. Spike solved the problem, just in 30 mins I deleted, unsubscribed, sorted all of them! Cool 😎 + automatic deletion feature is awesome 👍 Edit 2025-03-06: this app is still great, but giving it only 4 stars since some of my messages are still unread even if I have read them several times, thus a bit glitchy. I'm force to clean the app storage and log in back then go through all settings again. Please fix

1. Does not have HTML signatures. 2. Your email address is harvested and you get a "nice" but unexpected welcome email and are automatically subscribed to their newsletter. I don't know if my contacts' emails are being harvested as well. An email client should not be collecting my contact info!
