Knowing where you stand.
WHAT TO CHECK
Blacklists, for your domain and sending addresses Your platform's reported complaint and bounce rates Whether test messages authenticate correctly Whether messages land in inbox or spam at major providers
BLACKLIST CHECKS
Several free tools check your domain against the main lists.
A listing explains sudden delivery failure and should be investigated rather than merely delisted.
YOUR PLATFORM'S REPORTS
Bounce rate, complaint rate and unsubscribe rate.
Rising numbers indicate a problem before delivery collapses.
TESTING DELIVERY
Send a campaign to test addresses at the major providers and see where it lands.
Some services automate this across many providers.
WHAT AFFECTS REPUTATION
Complaints, hard bounces, sending to inactive addresses, sudden volume changes, and content signals.
IF YOU ARE LISTED
Find why. Delisting without fixing the cause means relisting.
Usually it is a compromised account sending spam, or a campaign to a bad list.
HOW OFTEN TO CHECK
Before any significant campaign, and whenever delivery seems to have changed.
