Add a sending domain.
Monitoring
Monitor sender-domain health before it hurts placement.
Create monitor schedules for sender identities, compare placement reports over time, and receive alerts when a score drops.
Live: monitor schedules create seed-list instructions and alerts. Automated send-as is not included yet.
Workflow
Simple enough to run before every important send.
Send each scheduled test from the same sending platform.
Track health and placement changes together.
Guide
Use the result as evidence.
When to use this
Domain health monitor is useful for teams that want early warning before domain problems hurt placement. The job is to connect sender-domain health signals with recurring placement history, using evidence that is specific to the sender and message path under test.
The main risk is discovering DNS drift, blacklist changes, or provider spam placement only after a campaign suffers. 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 authentication status, DNS checks, latest score, trend movement, next run time, and alert state. These signals help separate a broad sender problem from a provider-specific issue or a temporary pending state.
The checks to review are SPF, DKIM, DMARC, MX, PTR, BIMI, MTA-STS, TLS-RPT, blacklist signals, and provider placement. 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 add a sender, schedule comparable tests, review score changes, and alert on meaningful drops. 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.
Does Sendlander send the scheduled monitor emails for me?
Not yet. Sendlander creates scheduled seed-list instructions and alerts; you still send the test email from your normal platform.
Will this replace a DMARC platform?
No. Sendlander will focus on deliverability diagnostics, not full DMARC operations.
