Great with outbox flaws – Spark Mail + AI: Email Inbox Review

Great app. been using for years. Lately my emails sit in my outbox though, and it feels like a glitch with Spark saying email can’t be sent. Happens 3 or 4 times a day when i’m sending emails on my phone - frustrating if i don’t catch it because delivery is unreliable.
