These are SparkPost's components, named and scored by SparkPost. We do not map them onto the functions we check above, because we have no way to know which of their components our checks touch. Two lists, side by side, neither one rewriting the other.
This is SparkPost's own claim about their service, shown separately from what we measured. We never change our own numbers based on what a vendor reports, and this reading never changes theirs. Read both.
SparkPost response time, by region
Is it SparkPost, or is it you?
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 SparkPost -- it cannot diagnose SparkPost's own systems.
What we measured, function by function
SparkPost 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.

We will tell you when our probes stop reaching SparkPost, and again when they can reach it again. That is our own measurement from ten regions, not SparkPost's status page. No account, no card.

These are unverified reports from people using SparkPost, 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 SparkPost yet, which is not evidence that nothing is wrong.
Recent outages
measured entries are our own probes' readings; declared entries are the vendor's. How this check works
We have been measuring SparkPost since August 22, 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.

What SparkPost's SLA implies, from our measurement
At or above your target
We measured none of downtime for SparkPost over the last 30 days, which is 100% uptime by our reading. A 99.9% target allows 43 minutes over that period.
By our measurement there is no shortfall to claim for this period.
This is computed from our own probe measurements, not from SparkPost'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.
