How many outbound emails go out a day

#The daily cap

Sends go out 8 seconds apart, up to a cap per mailbox per day. The cap is 30 by default and is set for your account.

The cap counts emails sent, not drafts written, and each run only prepares what the busiest mailbox can still send that day.

#Mailboxes and subject lines

Drafts rotate across the mailboxes set up for your outbound, and subject lines rotate from a small pool, because a batch of identical subjects reads as a blast. Pacing keeps the sending mailboxes healthy.

#Large lists

Address lookups are capped at 150 a day by default, so a large list is worked through over several days. Each person gets at most one opener in 30 days.

#Follow-ups

Follow-ups are checked each day at 8am Eastern and go out in the same thread, up to two, three days apart.
