Every connected mailbox carries a reputation score out of 100, and it is one part of how Fuzegenai protects deliverability. Fuzegenai shows it on Email Accounts in the Reputation column, and uses it to decide how much campaign volume that mailbox is allowed.
The ratings you see
The Reputation column shows a word, a percentage and a bar. The word maps to the score like this.
| Rating | Score | Effect on campaign sending |
|---|---|---|
| Excellent | 90 and above | Full daily volume |
| Good | 75 to 89 | Full daily volume |
| Average | 50 to 74 | Full daily volume |
| Bad | 25 to 49 | About a fifth of the daily limit |
| Critical | Under 25 | Not used for campaigns |
You can filter the table by these with the Reputation dropdown, which lists All reputation, Excellent, Good, Average, Bad and Critical.
The separate Health column is an exception list, not a rating. A mailbox with nothing wrong reads Healthy. Otherwise it names what needs attention — Low reputation, Critical reputation, Limit reached, Warming, Paused, Sync error, Token expiring or DNS failing. Hover it for the full list.
What feeds the score
The score is built from signals that cannot be faked, over a rolling 14-day window that decays as it ages:
- Where your mail lands — inbox against spam folder. This is the largest single input.
- Bounces and complaints, both from warmup and from your real campaigns.
- Authentication pass rate for DKIM and DMARC. See Set up SPF, DKIM, and DMARC for your domain.
The score is capped while the evidence is thin. A mailbox with few observations, few active days or an early warmup level cannot score highly however clean it looks — the number has to be earned with volume and time. Scores are combined per provider and the worst provider wins, so a mailbox landing well on Gmail and poorly on Outlook is rated on the Outlook result.
Warmup replies, stars and forwards are deliberately excluded. Seed mailboxes perform those on a schedule, so they prove nothing.
The Warmup page shows the working (the warmup ramp itself is in What is domain warmup and how long does it take?): Placement, Confidence, Active days, Sample, Auth health, Worst ESP and a Per-ESP placement breakdown.
What happens automatically when it drops
The app reduces volume rather than cutting a mailbox off at the first bad day:
- Bad — the mailbox keeps sending campaign mail at roughly a fifth of its daily limit, so it can recover instead of digging deeper.
- Critical — the mailbox is not selected for campaign sends at all, and a mailbox that stays there is moved back to
WARMINGto re-warm. - Warmup volume is throttled by the score too, so a struggling mailbox is not pushed harder.
Bounces feed the score directly, so a high bounce rate is often the first cause to rule out; see Bounces: hard, soft, and what to do. If mail is already going to spam, work through Emails are landing in spam.
Scores update within about a minute of new signals arriving, with an hourly sweep as a backstop.
Google Postmaster Tools
Connecting Google Postmaster Tools is optional and adds Google's own view of your sending. Open the Postmaster Tools page, use Connect Google account for a domain, then Sync now. It shows Domain reputation, IP reputation, User-reported spam and SPF, DKIM and DMARC pass rates as Google reports them. Google needs the domain verified (Google's setup guide), around 48 hours, and steady daily volume to Gmail before there is anything to show. Your Fuzegenai reputation score is calculated without it.
If a mailbox is stuck at Bad or Critical and you cannot see why, write to priority@fuzegenai.com.
