FAQ
How does the spam detection work?
We send your newsletter content to seed email accounts we control across Gmail, Outlook, Yahoo, and Apple Mail. We then connect via IMAP to check whether each message landed in the inbox or spam folder, giving you real placement data — not estimates.
Who is this for?
Newsletter creators with 1,000+ subscribers who rely on email as a primary channel. If even 10% of your emails land in spam, you're losing significant reach and revenue. DeliverCheck helps you catch and fix issues before they compound.
Can I test before I send to my list?
Yes — that's the core use case. Paste your newsletter content, run a test, and get placement results within minutes. You'll see exactly which providers flagged your email as spam and get specific recommendations to improve deliverability before your real send.
