Deloosh counts how many campaign emails each person has received from you in the last 30 days, and it protects them at two levels: a soft cap that coaches you (around 4 by default) and a hard ceiling that blocks the send (around 8 by default). The hard ceiling denies with frequency_hard_ceiling.
The two levels
The soft cap is not a block. Cross it and the send still goes out. The send plan shows the configured Soft cap as a per-recipient coaching threshold. Its separate 30d sends figure is the workspace-wide total of marketing sends, so do not compare that tenant-wide number with the per-recipient cap.
The hard ceiling is a block. A recipient at or over the ceiling is denied, with a reason naming the count and the configured ceiling: “{recipient} at the hard ceiling: {n} cap-governed sends in 30d for tenant {your workspace} (ceiling {hard})”. The rest of the audience is unaffected — one person hitting their ceiling does not stop the send to everyone else.
The frequency check is per recipient over a rolling 30 days, and it counts campaign sends — marketing and cold outreach. It is not the tenant-wide 30d sends field and not a monthly volume budget for your workspace; that separate limit is covered in SEND-8, Monthly send caps.
About those numbers
Around 4 and around 8 are the shipped defaults, not a contract. They are configurable per workspace, so read them as Deloosh’s default judgment about email fatigue rather than a promised constant. The send plan shows the values actually in force for you.
Why fatigue is a deliverability problem, not just a courtesy one
Higher per-recipient frequency can increase fatigue, unsubscribe, and complaint risk. The soft cap makes that risk visible; the hard ceiling prevents campaign sends once the configured recipient-level limit is reached.
Review a recipient near the ceiling before adding another campaign send. If a whole cohort has dense recent histories and little recorded activity, consider the dormant-subscribers signal — see SIG-7, The dormant-subscribers (sunset) signal.
What to do when someone hits the ceiling
Wait for their 30-day window to roll forward, or narrow your audience so they are not in it. If you genuinely need a higher ceiling for your business, it is a per-workspace setting — ask in chat.
The pacing projection is separate: it advises whether to split a send or move its deadline, but does not yet spread the send automatically. See SEND-12, Safe-send-by, pacing, and “split or move the deadline”.
