Start Here

First, go to API Settings and save your EmailGuard API key and Instantly API key. The app only uses two keys total.

• EmailGuard is used for inbox placement, blacklist checks, and email host lookup.
• Instantly is used for inbox placement sending and blocklist management.

Inbox Placement

Use this to test if a sender email lands in inbox, spam, or fails.

• Add sender emails manually or import CSV.
• Select the senders you want to test.
• Click Test Selected.

Blacklist Checker

Use this to check if a sender domain is listed on blacklists.

• Add a domain or sender email.
• Run Check or Check Selected.
• Review blacklist count, health, and details.

Email Host Lookup

Upload a CSV with an Email column. The app keeps the original columns and adds new export columns.

• Email Host
• Proofpoint
• Email Host Status
• Email Host Checked At

Instantly Blocklist

Use this to block or unblock emails and domains in Instantly.

• Add an email or domain.
• Click Block to add it to Instantly.
• Click Unblock to remove it from Instantly.

Common Fixes

• If something fails, check API Settings first.
• If a new page does not work, restart the server with Ctrl + C, then npm start.
• If CSV upload fails, make sure there is an Email column.
• If sidebar changes do not appear, hard refresh with Ctrl + Shift + R.
