Sending Limits
Daily quota caps per mailbox
Gmail free: 500/day · Workspace: 2,000/day.
Separate from campaign quota.
0 = no retries. 1 = one retry.
Reply-To Address

Leave blank to use each sender's own address. A dedicated reply-to helps track replies and looks more professional.
Delay & Batch Defaults
Default values pre-filled in campaign sending mode
Shortest gap in Random Delay / Burst modes.

Test Email Defaults
Pre-filled values in the Send Test Email modal

Subject used when no custom subject is entered.
Override the built-in test template with a custom one.
Email Open Tracking
One-time setup for live open-rate tracking
Public URL where this app is reachable. Required for tracking pixels — without it, open tracking is inactive for all campaigns. Your own app URL works; no separate tracking domain needed.
✓ Tracking active for campaigns with "Track opens" enabled.
How it works
A 1×1 tracking pixel is embedded in each email. When a recipient opens the email, the pixel loads from your app and the open is recorded.
Open tracking requires campaigns to have Track Opens enabled at launch. Pixel is only injected when the App Base URL is set.
Sender → Lead Provider Routing
Match senders to leads by email provider (Gmail→Gmail, Microsoft→Microsoft)
Off: All senders rotate equally across all leads regardless of provider. Default behaviour — no provider matching.
Requirements
  • Leads must be scanned for provider on the Leads page.
  • Senders matched by account type: Outlook OAuth = Microsoft, Gmail OAuth = Google, SMTP = inferred from host.
  • Smart mode fills in from the full pool when no matching sender is available — safest choice.
  • Strict mode skips leads with no matching sender — use only when you have senders for every provider type.
