Is Mailchimp down?
Partially degradedchecked 2 minutes ago
Mailchimp is answering our probes, but its web surface is running at least 0.6x its 7-day median from UK, Asia-Pacific, US-Central, Southeast Asia, US-West and Australia. Everything else we check answered at its usual speed.
As of Oct 19, 2026, 8:53 PM UTC, RealUptime's checks of Mailchimp passed in all 10 regions that returned a reading.
Our checks of Mailchimp did not fail from two or more distant regions in the 60 days we have checked it (since Aug 20, 2026). This does not show Mailchimp works for users.
Mailchimp publishes no status feed we can read, so the only reading here is our check reading on the left.
Mailchimp response time, by region
Check your own site while you wait on Mailchimp
Watching an outage above does not tell you whether your own connection or site is also having a problem. Enter your own URL for one live check, right now, no signup. This checks the site you enter, not Mailchimp. It cannot diagnose Mailchimp's own systems.
What we measured, function by function
Mailchimp answers on more than one surface, and they can fail apart. Each row is one surface, checked from the same regions. The verdict above follows the api row, because that is the surface we treat as this service's own; a failure on any other row is a partial outage, not a full one.

These are unverified reports from people using Mailchimp, counted separately from what our own probes measure. Anyone can file one, no account is needed, and the region on a report is chosen by the person filing it. We never open, extend or close an outage in our record based on report volume: only our own measurements do that. We have not received any reports for Mailchimp yet, which is not evidence that nothing is wrong.
Recent probe events
No probe events on record yet for Mailchimp.
check entries are our own probes' readings; declared entries are the vendor's. How this check works
We have been measuring Mailchimp since August 20, 2026. We show nothing from before that date, and we never add an outage we did not observe ourselves, from any source.

Monitor your own site the same way
This page shows what we see when we check this service, using the same ten regions, for a site you run. RealUptime Monitor watches your own servers from inside your network, and it starts free.

The window is printed on it, so the number always says what period it covers. If our readings go stale it says stale, and if we have no readings it says so and shows no color. Free, no account, and it links back here. See how the badge works for every window and the honesty rules behind it.

Checking a site of your own? The free website down checker sends it one request and reports the answer, and the SLA calculator shows how much downtime an uptime figure allows.
How our checks compare with Mailchimp's stated SLA
At or above your target
Our checks of Mailchimp failed for none over the last 30 days, which is 100% uptime by our checks. A 99.9% target allows 43 minutes over that period.
Our checks show no gap in this period. That does not rule out one you saw.
These figures come from our own checks of one public endpoint per service. They are not the service's real uptime. This is computed from our own checks, not from Mailchimp's SLA instrumentation. Their contract is normally measured against their own systems, with their own exclusions and a claim window, so their figure and ours will differ. Use this to start the conversation and ask for their number. It is not legal advice and it is not a determination of what you are owed.
What we check
What our check can and cannot see
A pass means the service's servers answered with the sign-in refusal they give any request that is not signed in. It does not show that sign-in works or that anything behind the sign-in wall responds.
