Fair-use sending policy

The monthly send allowance, why it exists, and what happens near the limit.

Every simulation leaves from a shared, reputation-managed sending service. To protect inbox delivery for everyone on that service, each organization has a monthly send allowance. It is a fair-use ceiling, not a billing meter, and it applies on every plan, including Free.

Your monthly allowance

The allowance is a multiple of your active headcount. The multiplier widens for larger organizations, since they legitimately run bigger, split campaigns:

  • Every organization: at least 250 sends per month, whatever your headcount.
  • Up to 200 employees: 2.5× headcount. Example: 200 people → 500 sends per month.
  • 201 to 600 employees: 3.0× headcount. Example: 600 people → 1,800 sends per month.
  • 601 to 1,000 employees: 3.5× headcount. Example: 1,000 people → 3,500 sends per month.

The 250 floor means a small team is never starved: below roughly 100 people the headcount multiple would fall under it, so you get the floor instead. A 200-person org, for instance, comfortably runs two full campaigns a month with room to spare, or one campaign split across teams. The allowance resets at the start of each month.

What counts, and what doesn’t

  • Counts: real simulation emails sent to your people.
  • Does not count: test emails you send to yourself while building a campaign.
  • Does not count: security-training emails.

Near or over the limit

  • Around 80% of your allowance, a heads-up appears on the Campaigns page and in the launch step.
  • At 100%, new launches pause. Anything already scheduled or sending is unaffected, and launches resume automatically when the allowance resets.

Need more room in a given month? Top-up packs are on the way; until then, get in touch and we’ll sort it out. See our Acceptable Use Policy for the rules on who you may simulate.
