Guide
Use the result as evidence.
When to use this
Email deliverability test is useful for operators who need to know whether accepted email is actually visible. The job is to separate transport delivery from mailbox folder placement, using evidence that is specific to the sender and message path under test.
The main risk is assuming delivered events mean recipients saw the message in the primary inbox. Sendlander keeps the workflow grounded by tying the page back to real reports, real seed results, and visible diagnostic checks instead of generic deliverability advice.
What the report should prove
The useful evidence includes accepted send path, seed matches, folder results, provider summaries, latency, and report history. These signals help separate a broad sender problem from a provider-specific issue or a temporary pending state.
The checks to review are bounce and delivery context, inbox placement, authentication, sender identity, links, and content risk. The result should lead to one or two concrete fixes, not a vague list of every possible deliverability concern.
How to act on it
A practical workflow is to use delivery logs for transport health, then use Sendlander reports to check inbox, spam, and pending placement. After each meaningful change, rerun a comparable test so the team can tell whether placement improved.
Use this page as an entry point into the product, then save the report in the dashboard when the result matters. Saved reports make follow-up tests easier to compare and keep the next fix tied to evidence.
Details
Focused answers.
What does this test measure?
It measures where seed inboxes receive the email. It does not guarantee every real recipient will see the same placement.
Can I test cold email campaigns?
Yes, but you are responsible for the legality and permission basis of your campaigns.
