Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.02442 |
| Opus 5 | $0.00051 | $0.01221 |
| Sonnet 5 | $0.00020 | $0.00488 |
| Haiku 4.5 | $0.00010 | $0.00244 |
Grade A, and why
smartlead-inbox-manager scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to smartlead-inbox-manager — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Smartlead Inbox Manager
Zapmail hands you hundreds of new inboxes. Smartlead needs them configured: warmup enabled with the right ramp, signatures set so emails don't look bare, tags applied so you know which are active vs insurance, and health monitored so dead inboxes get recycled.
This skill does all of that via the Smartlead API.
Core operations
| Operation | What it does | Script |
|---|---|---|
| Enable warmup | Turns on warmup with correct ramp (start 1/day, +5/day up to 40/day) | set-warmup.ts --mode=enable |
| Disable warmup | Turns off warmup (use for insurance inboxes) | set-warmup.ts --mode=disable |
| Set signatures | Bulk-applies a signature template to inboxes | set-signatures.ts |
| Tag as active | Adds the "active" tag | tag-inboxes.ts --tag=active |
| Tag as insurance | Adds the "insurance" tag | tag-inboxes.ts --tag=insurance |
| Health dashboard | Lists all inboxes with warmup status, reputation, daily sent | list-health.ts |
Active vs insurance (the tagging convention)
Not every inbox should send all the time. A common pattern:
- Active inboxes — currently sending in live campaigns. Warmup OFF (or minimal) to prioritize real sends.
- Insurance inboxes — warmed but idle, held in reserve. Warmup ON to maintain reputation. Swap in when an active inbox burns out.
Tags are how you track this at scale. Filter by tag in Smartlead UI or via API.
Inputs
Every script reads:
SMARTLEAD_API_KEY(env var)- Inbox selector:
--ids=1,2,3OR--domain=example.comOR--tag=insuranceOR--all - Operation-specific flags (see each script)
Warmup ramp settings
Default warmup config for a NEW inbox (week 1-4 of warmup period):
{
"warmup_enabled": "true",
"total_warmup_per_day": 40,
"daily_rampup": 5,
"reply_rate_percentage": "20"
}
total_warmup_per_day: max emails/day the inbox sends in warmup network (peak)daily_rampup: increment per day (day 1 = 1, day 2 = 6, day 3 = 11, etc. up to the cap)reply_rate_percentage: how often warmup peers reply (20% is realistic)
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
