Frequently asked questions

What is inbox placement?
Inbox placement is the percentage of your sends that actually land in the recipient's primary inbox, as opposed to the Promotions tab, the spam folder, or being dropped silently. It's the metric that matters; delivery rates from your ESP only count what didn't bounce.
How does inbox placement testing work?
We give you a seed list of real mailboxes across every major provider. Add the list to your campaign as you would any other recipient, and we'll generate a report showing exactly where your message landed at each provider.
Which providers do you support?
All the big ones: Gmail, Outlook / Microsoft 365, Yahoo, iCloud, AOL and regional providers including Comcast, Orange, Mail.ru, GMX and more.
How many blacklists do you monitor?
We continuously monitor your domains and IPs against 120+ real-time blacklists, including Spamhaus, SpamCop, Barracuda, SORBS, URIBL and every other reputation list that matters.
What's email warmup?
New sending domains start with zero reputation. Warmup gradually increases volume in a pattern that mailbox providers recognize as healthy, so you don't get throttled or filtered when you ramp up.
How does authentication monitoring work?
We continuously verify your SPF, DKIM and DMARC configuration, and check that every sending source aligns with your published policy. You'll get an alert the moment something drifts.
