Track blocklists, complaints and authentication health, with alerts and clear next steps.
AI risk scoring warns of reputation drift and explains the fix in plain steps.
Daily checks of your IPs and domains across major lists.
We check your sending IPs and domains against major blocklists every day. A listing that would otherwise surface as unexplained bounces is flagged early, with the list named so you know exactly where to look.
Follow complaint rates by domain and stream.
Complaint rate is one of the strongest signals mailbox providers use. Follow it by domain and by stream so a problem campaign is easy to find and stop before it affects the rest of your mail.
Spot SPF, DKIM or DMARC regressions.
SPF, DKIM and DMARC settings drift when DNS is edited or a new tool is added. Authentication health shows regressions as they happen so a quiet misconfiguration does not cost you inbox placement for weeks.
Email or webhook when a threshold is crossed.
Set thresholds and get email or webhook alerts when they are crossed. The right person hears about a problem while there is still time to fix it, without watching a dashboard all day.
Each issue links to the step that resolves it.
Each issue links to the step that resolves it, so you move from 'something is wrong' to 'here is what to change' without searching documentation. Fixes are written for operators, not only for deliverability specialists.
Know how to request removal and what to fix first.
When a listing happens, knowing how to request removal and what to fix first saves days. We explain the process for each list and the changes that make removal likely to stick.
Everything you send from is monitored automatically.
Choose when you want to be alerted.
Follow the guidance attached to each alert.
Each stage plays automatically. Select one to pause on it. Illustrative interface: all figures and addresses shown are sample data.
A listing or a rising complaint rate rarely appears without warning. The monitor makes the warnings visible.
Email reputation monitoring is the continuous tracking of the signals that decide whether mailbox providers trust your mail, including blocklist listings, complaint rates and authentication health. MigoSMTP monitors your sending IPs and domains, checks them against major blocklists, and alerts you by email or webhook when a threshold is crossed or an address is listed. Checks run automatically on a schedule, so nobody has to remember to look, and results are kept as history you can compare against later.
You add your domains and IPs, set the thresholds that matter to you, and follow the guidance attached to each alert. Authentication monitoring spots regressions in SPF, DKIM or DMARC, such as a record that stopped aligning after a DNS change. History shows what changed and when, and the free blacklist check tool handles quick lookups. Thresholds are yours to set, and alerts can go to a person, a shared mailbox or a webhook that opens a ticket automatically.
Reputation problems rarely appear without warning. A rising complaint rate or a minor listing precedes broader blocking, and fixing them while small protects inbox placement. Our AI features score risk, explain the likely cause of each alert in plain English and suggest next steps, while leaving decisions to your team. Used with analytics and warmup, monitoring gives a complete view of what is helping or hurting your standing at each provider.
Daily checks flag when a sending IP appears on a blocklist. You see which list, why it is likely, and what to fix before requesting removal.
Track complaints separately for marketing and transactional streams. If marketing complaints climb, you can pause or segment that stream before it affects critical messages. Isolation protects what matters most.
After a DNS migration, monitoring shows if SPF or DKIM stopped passing for part of your traffic, so you correct it before mailbox providers start filtering.
Pair reputation alerts with a warmup plan. If signals turn bad during the ramp, you hear about it the same day and can slow volume.
Add a domain you have just taken on and see its blocklist status, authentication health and complaint signals before you send anything.
Use the monitor history to show leadership or clients how reputation has moved, and what you changed when it did.
A free lookup answers one question once. Monitoring tells you when something changes.
The free check is useful for investigating a single address. The monitor is what protects day-to-day sending.
A reputation risk score combines complaint trends, bounces, authentication health and listing signals into one indicator with the factors behind it. You set the level at which alerts fire.
When an alert fires, the copilot lists likely causes, such as a stale segment or a missing DKIM selector, and links the relevant guide. You verify and act on it.
Trend models project whether a complaint or bounce rate is heading toward your threshold, giving you notice before the line is crossed. Forecasts are estimates, not guarantees.
For listings, the assistant drafts the removal request and a checklist of fixes to complete first. You review the text and submit it yourself. Everything is reviewable afterwards.
AI features are assistive: they score, explain and draft, and your team decides what to change and what to submit.
Requesting removal without addressing the reason often leads to relisting. Remove bad addresses, stop risky sources and confirm authentication first.
Start with monitoring, move to enforcement once aligned traffic is clean, and review reports for sources you did not know were sending.
Include a clear unsubscribe and honour it quickly. Track complaints per stream so one problem list cannot hide in a healthy average.
Mail engaged contacts first and reduce frequency to inactive ones. Poor engagement is a quiet reputation drain that rarely triggers a listing on its own.
When a customer reports missing mail, check the sending IP and domain right away. It rules out or confirms a listing in seconds.
Add all of them, including ones used rarely. A listing on a forgotten address is usually found only after mail fails.
Listed on a blocklist and unsure what to do? Our team can review it with you.
Email blacklist monitoring regularly checks whether your sending IPs or domains appear on blocklists used by mailbox providers, and alerts you if they do. Early notice lets you fix the cause and request removal before delivery suffers widely. Early alerts prevent surprises.
The reputation monitor shows the lists checked for each IP and domain, and the free blacklist check tool lets you look up a single address. Coverage can differ by list type, so the monitor view shows the exact set that applies to your account.
Read the alert, which explains the likely cause and the removal steps for that list. Fix the underlying issue first, such as a compromised account or bad list, then submit the removal request. Re-check after a day or so. Wait a day before rechecking.
Yes. Use the free blacklist check tool to look up an IP or domain without setting up monitoring. Monitoring adds scheduled checks, history and alerts. Monitoring adds history, thresholds and alerts, so you hear about a listing without having to remember to look. Quick checks are helpful for ad hoc questions from colleagues and customers.
IP reputation reflects the behaviour of mail sent from a specific address. Domain reputation follows your sending domain wherever it sends from. Mailbox providers use both, so monitor both, especially when you change providers or IPs. Both can move independently of each other.
Authenticate with SPF, DKIM and DMARC, send only to people who want your mail, remove bounces and inactive addresses, keep complaints low and ramp volume gradually on new IPs. Consistency over weeks matters more than any single fix. Review the results every week.
AI combines signals into a risk score, explains the likely causes of alerts, forecasts drift toward your thresholds and drafts delisting requests. You review and decide every action. Scores are guidance, not a guarantee of placement.
History helps you see what changed around the time a problem began. How far back it goes depends on your plan, so check your plan details and export key reports if you need records for audits or post-incident reviews.
