Do your emails land in the inbox, or in spam?
UpperBuss shows your delivery health at a glance: bounce rate, replies, spam complaints and warmup status, in traffic-light colors.
At a glance · Traffic-light colors · No extra cost · In progress
Two layers, one view
Mailbox health (warmup, health score, daily limit) and 30-day sending health (bounce rate, replies, spam complaints, unsubscribes), summarized on one page.
Traffic lights, not guesswork
Green, yellow, red: a high bounce rate or low reply rate stands out immediately, before it hurts your domain reputation.
Honest about the limits
These figures show your delivery health, not the exact inbox-vs-spam placement, only a seed test measures that. But bounces, complaints and replies warn you early.
No extra cost
Based on your own sending data and warmup, no expensive extra tool, no additional subscription.
