What’s new
Changes to ProbeKit, newest first.
Bounce codes, a status page, renewals, and an app for your phone
- A bounce code library (/bounce): SMTP reply codes, enhanced status codes, and common bounces from Microsoft, Gmail, Yahoo, and other providers, each with what it means, the likely causes, and the fix.
- ProbeKit’s own status page (/status): the website, API, monitoring, DMARC ingestion, and mail, checked every minute, with 90 days of history and any incidents.
- Dashboard → Renewals: every domain and certificate expiry you watch in one calendar, soonest first, with reminders at 60, 30, 14, and 7 days, and a CSV export (Pro and MSP).
- Install ProbeKit on your phone or desktop from the browser, like an app.
- A short tour of the dashboard the first time you sign in, and a clear next step on every empty list.
- The Email Header Analyzer now explains how to copy the full headers in Gmail, Outlook, and Apple Mail, and what it shows you.
- Every tool page starts with a two-sentence explanation of what the tool does and when to use it.
For MSPs: client import, PSA tickets, reports you can show
- A page for MSPs (/msp) with the per-client math, a sample white-label client report and a live demo status page.
- Clients → Import: upload a CSV of clients and domains, see what will happen to every row, then create them in one go.
- “Monitor everything” on a client sets up Domain Health, DMARC, SPF, DKIM, blacklist, certificate and DNS-change monitors for each of its domains.
- The client page shows domains, monitors, open incidents, DMARC, the status page and the report schedule together.
- Autotask and ConnectWise Manage: a ticket per incident, a note when it’s acknowledged, closed when it clears (MSP plan).
- The MSP plan now has a 14-day free trial, like Pro.
- Referral links: whoever signs up through yours gets a 30-day trial; you get a month free when they first pay.
- Status pages show a small “Monitored by ProbeKit” badge (optional on MSP).
- Comparison pages for dmarcian, EasyDMARC, DNSChecker and Hardenize.
Watch your domains, share results, see the trend
- Pick alert channels on the monitor form itself, and add an email, Slack, Teams, Discord, PagerDuty or webhook channel without leaving it.
- When a monitor finds something real (a certificate about to expire, a new blacklist listing, SPF or DMARC broken, a DKIM key gone, a DNS change, a domain about to lapse, a site down) owners and admins get a short email with the fix. At most one a day per monitor.
- “Monitor everything on this page” under Domain Health adds the monitors that domain doesn’t have yet, within your plan.
- Share any result as a public link (not indexed, 90 days, you can turn it off).
- Monitor pages show uptime and response time (median and p95) or status over 7, 30 and 90 days, with incidents marked.
- The dashboard groups monitors by domain (and by client on MSP); every row, status and history dot links to the monitor, and “This was me” acknowledges a change you made.
- Domain Health weighs blacklists: a minor list on your mail provider’s server is a warning, not a failure.
Smart search, passkeys, status pages and Explain & Fix
- One smart search box on the home page, dashboard and header: type a domain, IP, email or URL and pick a check. Press / to focus it.
- Paste a bounce anywhere you search and Diagnose opens with it.
- Domain fields remember your recent entries, on this device or across devices when you’re signed in.
- Every result now suggests the next checks to run, and you can save or export it.
- Works properly on phones: a menu, card layouts for tables and a Run button that stays in reach.
- Sign in with a passkey (Face ID, Touch ID, Windows Hello or a security key). Forgot-password links now expire after 30 minutes and work once.
- New monitors: ping, TCP port, SMTP + STARTTLS, DKIM selector, MTA-STS + TLS-RPT, nameserver consistency, security headers and a daily Domain Health score. Certificate monitors now also catch chain and TLS changes.
- Public status pages for your domains or clients, branded on MSP.
- “Explain & Fix” turns any result into a verdict, the impact and the exact records to paste (where AI is enabled).
- Plans page with monthly and annual prices and a full comparison; usage meters in Account.
- New pages: how to get delisted from each blocklist, SPF/DKIM/DMARC setup for Microsoft 365 and Google Workspace, and ProbeKit vs MxToolbox.
- Fixed: the site header could disappear in Safari 26.
Diagnose
- Paste a bounce, NDR or SMTP error and get the cause and fix instantly, plus 22 guides for the most common errors.
Monitoring, DMARC reports and the API
- Monitors with email, webhook, Slack, Teams, Discord and PagerDuty alerts.
- Hosted DMARC aggregate report ingestion with dashboards.
- A REST API with an OpenAPI spec, and the weekly digest.
