If sending to multiple people within a company (domain), the innate option to send to one person per domain for the entire sequence, and only send another to another person within the domain after no replies from the previous person.

For example, let's say I have the two leads, ceo@acme.com and cmo@acme.com. I would like to be able to 1) send as normal, meaning it will send to all parties regardless of replies. 2) priotize this who to send to first, and only if there are no replies after the sequence more on to next priortized contact 3) just stop sending out to other accounts within the same domain if anyone from that domain replies (instantly has option 3).

This is important because at times we are working different angles of getting "into" an organization, and we may not know who will reply first. We don't want the perception of "going around" someone we are already conversing with and lose good will.
