Most deliverability problems are discovered after a campaign has already gone out: replies dry up, bounces climb, and nobody can say whether the problem is the list, the mailboxes or the domain. Two checks before you send remove most of that guesswork: validating the list, and testing where your email actually lands.
Validate the list first
Invalid addresses bounce, and bounces hurt the reputation you spent weeks building during warm-up. Email Validate checks every address before it is used in a campaign.
CheckValidity
- What it tells you
- Whether the address is correctly formed and can exist
CheckDeliverability
- What it tells you
- Whether mail sent to the address is likely to be accepted
CheckMailbox status
- What it tells you
- Whether the mailbox exists and is active
CheckCatch-all status
- What it tells you
- Whether the domain accepts every address, so a pass says little
| Check | What it tells you |
|---|---|
| Validity | Whether the address is correctly formed and can exist |
| Deliverability | Whether mail sent to the address is likely to be accepted |
| Mailbox status | Whether the mailbox exists and is active |
| Catch-all status | Whether the domain accepts every address, so a pass says little |
Then test placement
Inbox Placement sends a test and compares where it lands across inbox and spam or junk, then shows the percentage that reached the inbox. A strong result means you can launch with confidence. A weak one means you fix the problem first.
Reading a weak result
- Check InfraGuard for the domain: score, blacklist status, DNS checks, bounces and IP / IPT monitoring.
- Check Email Insights for the mailboxes: bounce rate, reply rate and email health status.
- If the mailboxes are new, give warm-up more time. 2 to 3 weeks is the minimum, not the target.
- Re-run the placement test after each fix so you know which change made the difference.
Make it routine
Validate every new list and run a placement test before every new campaign. Both take minutes, and both are cheaper than recovering a damaged domain.
