First, confirm it is actually Mailchimp and not your store. Then contain the damage and communicate. Here is exactly how to do that during a Mailchimp outage, plus what usually breaks and how long incidents tend to last.
How do I confirm Mailchimp is actually down?
Check two independent sources before changing anything in your store. First, StatusBird's live Mailchimp status page, which is based on independent checks every 2 minutes. Second, Mailchimp's own status page at status.mailchimp.com/. If the official page still shows green, do not assume you are wrong: vendors often acknowledge incidents well after they start. If both look clean, the problem is more likely your store's configuration or a specific integration.
What does a Mailchimp outage look like?
- Mailchimp dashboard not loading or logins failing
- Scheduled campaign stuck or showing no delivery activity
- Automation and journey emails not arriving
- Embedded signup forms or Mailchimp landing pages not loading
- Store integration showing sync errors or stale audience data
What breaks in your store
During a Mailchimp outage, scheduled campaigns may not send and automations like abandoned cart journeys stop firing, pausing the revenue those emails normally drive. The dashboard can be unreachable, so you cannot build, edit, or check on sends mid-promotion. Mailchimp-hosted signup forms and landing pages may fail to load, halting list growth, and store integrations stop syncing new customers and orders, which delays automation triggers even after recovery.
For context, Mailchimp has had no major incidents in the last 90 days of StatusBird's independent monitoring (100.0% availability), so a real outage is unusual. That makes it easy to mistake one for a problem on your end, which is why confirming first matters.
What to do during the outage
- Check status.mailchimp.com to distinguish a dashboard outage from a sending outage, since campaigns sometimes deliver even when the UI is down.
- Hold time-sensitive campaign launches until sending is confirmed healthy.
- Verify a stuck campaign's delivery stats after recovery before resending, to avoid emailing your list twice.
- Replace links to Mailchimp-hosted landing pages in active ads with pages on your own domain.
- After recovery, confirm your store sync caught up and that automation triggers fired for outage-window carts and orders.
Frequently asked questions
My promotion email was scheduled during the Mailchimp outage. Do I need to resend it?
Check first. Queued campaigns often send late once the outage clears, and resending blindly risks double emails to your entire list. Look at the campaign's delivery report after recovery; only resend, and only to unsent recipients, if delivery clearly failed.
Will my abandoned cart automation catch the carts abandoned during the outage?
Often yes with delay, since the store sync backfills events and journeys process them late. But it is not guaranteed for every event, so review automation activity for the outage window and consider a manual send to any high-value abandoned carts that slipped through.
After the outage
Once Mailchimp recovers, verify the affected workflows end to end rather than trusting the status page. Note the start and end times while they are fresh: if you are on a paid Mailchimp plan with an SLA, documented downtime is what a service credit claim is built on. See how to claim SLA credits for the process.
How this data is measured
StatusBird checks Mailchimp's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the Mailchimp reliability page and current status on the Mailchimp status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors Mailchimp and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up. Start monitoring free, no card required for the free plan.
