Know exactly where you'll land — before you send
Sendcheck.io predicts whether each email will reach the inbox and which tab it will land in — Primary, Promotions, Updates or Spam — across Gmail, Outlook, Yahoo and Apple Mail. It analyses your content, checks SPF, DKIM and DMARC authentication, and identifies spam risks using the same signals inbox providers use, so you can fix issues before subscribers ever see them.
- Predicted placement across all four major providers
- SPF / DKIM / DMARC checks
- Spam score analysis
Never send a broken merge tag again
Nothing damages trust faster than 'Hi {FirstName}' going out to 50,000 people. Sendcheck.io detects broken merge tags, missing personalisation, and Liquid syntax errors.

A note from the founder
“I built sendcheck.io because sending an email campaign shouldn't feel stressful. Every send came with the same questions: Did I catch every mistake? Did I test every link? Is something going to break when it reaches thousands of subscribers? The review process was slow too — hours spent waiting for feedback and chasing approvals. So I built sendcheck.io: a tool that checks your emails, finds issues, and tells you exactly how to improve them before you hit send. In under 60 seconds.”
