The throttle
Attaching prospects to a campaign does not email them all at once. New prospects begin the sequence at the rate set by the campaign's Daily Prospect Start — 50 per day by default.
Why it defaults to 50
Volume control is deliverability control. A brand-new or low-volume mailbox that suddenly sends hundreds of cold emails a day gets filtered. Starting at 50/day per campaign and letting your Daily Sending Limit (per mailbox, in Settings) act as the backstop keeps sending patterns natural.
Choosing a number
- New mailbox or new domain — start low (10–30/day) and ramp over weeks.
- Warm, established mailbox — 50–100/day is a common working range.
- Multiple campaigns on one mailbox — remember the per-mailbox Daily Sending Limit caps the combined total.
Checking who's in flight
The Outbox shows exactly what's scheduled (Scheduled), currently going out (Processing), and what's gone (Sent) — the ground truth for "who got emailed today".
