# Contact several people at one company

> Set how many people at the same company a sequence will reach, and stop the rest when one of them replies.

**Multithreading** controls how a sequence behaves when several of its contacts share a company. Cap how many of them it reaches, space out when it reaches them, and decide whether one reply speaks for the rest.

## Set the rules

<Steps>
  <Step title="Open Multithreading">
    In the sequence editor, open **Settings** and find the **Multithreading** section.
  </Step>

  <Step title="Set a company limit">
    Type a number into **Set a company limit**, or leave it as **No limit**.
  </Step>

  <Step title="Turn on Sequential sending within a company">
    One colleague is contacted at a time; the sequence waits for an outcome before moving to the next.
  </Step>

  <Step title="Turn on Stop on reply from company">
    When anyone at the company replies, their colleagues' scheduled sends stop as well.
  </Step>
</Steps>

## Good to know

<AccordionGroup>
  <Accordion title="How does the sequence know which contacts share a company?">
    By the **Company** column mapped on the Audience tab. Map that column for the company limit to have anything to count.
  </Accordion>

  <Accordion title="What happens to the rest once the company limit is reached?">
    They do not get contacted through this sequence. The limit is a ceiling on the whole company, not on each colleague.
  </Accordion>

  <Accordion title="Does Sequential sending wait a fixed amount of time?">
    No. It waits for an outcome at the current step, not a timer, before moving on to the next colleague.
  </Accordion>

  <Accordion title="Why are both settings marked Recommended?">
    Emailing a whole company at once, or ignoring one colleague's reply while others keep hearing from you, reads as spam rather than outreach.
