How many days for your list?

A simple estimate of the time needed to start first contacts.

Your first-contact pace

First contacts spread over20 sending daysEstimate, excluding follow-ups and interruptions

50 new people per day across all mailboxes.

Sending days, not a guaranteed date

The result divides people by the daily first-contact capacity across mailboxes, rounded up to a whole day. If you send only Monday through Friday, five sending days generally correspond to one calendar week.

What can extend the duration

This model does not simulate follow-ups, their priority, total sending caps or a gradual volume ramp. Pauses, errors, time zones and provider limits can also affect duration. The result is not a delivery promise.
