EMAIL — MARKETING, COLD OUTREACH & DELIVERABILITY

Paid links. We earn a commission if you buy through links on this page. It never changes our ranking — see how we rank.
Pricing
We do not reprint prices. They change too often for that to be honest, and a number on our page with no date is worse than sending you to the source.
How we rated it
What it is
Tests email deliverability: sends to seed inboxes across providers and reports where it landed, plus blacklist and authentication checks.
Who it is for
Anyone sending email at volume who needs to know whether it is arriving.
Where it is strongest
Finding out that Outlook is sending you to spam before you discover it through a silent month. Spam placement is otherwise invisible — nobody tells you.
Where it falls short
Seed inboxes approximate real ones rather than matching them, so results are indicative. Credit-based pricing. And it diagnoses; fixing reputation is slow work it cannot do.
Our verdict
Recommended for serious senders, because the alternative is finding out from a drop in replies weeks later. Expect it to tell you that you have a problem, not how to fix it.
