aibot88 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)
For INSURANCE inboxes (maintaining reputation long-term):
{
"warmup_enabled": "true",
"total_warmup_per_day": 15,
"daily_rampup": 0,
"reply_rate_percentage": "20"
}
Lower volume, no ramp — just keeps the inbox warm.
For ACTIVE inboxes (currently in live campaigns):
{
"warmup_enabled": "false"
}
Warmup off so the daily send budget goes to real prospects.
Signature template
The default template, applied in bulk via set-signatures.ts, is:
{from_name}
{title}
{company}
{address}
Rendered (for example):
Jane Smith
Founder
Acme
123 Main St, Suite 400, Austin, TX 78701
Where each value comes from:
{from_name}— the inbox's ownfrom_namefield if set (different personas per inbox), elseSENDER_FIRST_NAME + SENDER_LAST_NAMEfrom.env{title}—SENDER_TITLEenv var{company}—SENDER_COMPANY_NAMEenv var{address}—SENDER_PHYSICAL_ADDRESSenv var (REQUIRED by CAN-SPAM — always include a real mailing address)
Required .env entries for the default template:
SENDER_FIRST_NAME=Jane
SENDER_LAST_NAME=Smith
SENDER_TITLE=Founder
SENDER_COMPANY_NAME=Acme
SENDER_PHYSICAL_ADDRESS=123 Main St, Suite 400, Austin, TX 78701
Custom template override:
# Pass inline (use \n for newlines)
npx tsx scripts/set-signatures.ts --all --template="Cheers,\n{from_name}\n{title}\n{company}\n{address}"
# Or from a file
npx tsx scripts/set-signatures.ts --all --template-file=./my-signature.txt
Available placeholders: {from_name}, {from_email}, {domain}, {title}, {company}, {address}.
Email body order in campaigns:
In Smartlead sequences, always end the body with %signature% — Smartlead injects the inbox's signature there. Order:
<body content>
<PS unsubscribe line>
%signature%
This puts %signature% (with name + title + company + address) on the bottom, satisfying CAN-SPAM's physical-address requirement automatically for every inbox.
Health dashboard output
list-health.ts prints a CSV + summary:
email warmup reputation sent_today health_status
john@example.co on good 18 healthy
jane@example.co on fair 5 warming
sales@other.co off n/a 28 active
support@other.co on bad 0 blocked
Summary:
Total inboxes: 80
Warmup on: 50
Active (warmup off): 28
Blocked/failed: 2
Reputation:
Good: 65
Fair: 10
Bad: 3
Unknown: 2
Action items:
- 2 inboxes blocked — run /email-deliverability-audit
- 3 inboxes with "bad" reputation — consider pausing
Common workflows
Day 1 after Zapmail provisioning
# 1. Enable warmup on all newly created inboxes
npx tsx scripts/set-warmup.ts --mode=enable --tag=new --warmup-per-day=40 --ramp=5
# 2. Set signatures
npx tsx scripts/set-signatures.ts --tag=new --template="Best,\n{from_name}"
# 3. Tag them as insurance (they aren't active yet — warmup for 2 weeks first)
npx tsx scripts/tag-inboxes.ts --tag=new --add-tag=insurance
npx tsx scripts/tag-inboxes.ts --tag=new --remove-tag=new
Activating insurance inboxes into a live campaign
# 1. Identify warm insurance inboxes with good reputation
npx tsx scripts/list-health.ts --tag=insurance --filter=reputation:good --out=activate-candidates.csv
# 2. Flip them to active
npx tsx scripts/tag-inboxes.ts --ids-from-csv=activate-candidates.csv --add-tag=active --remove-tag=insurance
# 3. Disable warmup (they're sending for real now)
npx tsx scripts/set-warmup.ts --mode=disable --tag=active
Weekly health check
npx tsx scripts/list-health.ts --all --out=health-$(date +%Y-%m-%d).csv
Review the action items. Replace blocked inboxes.
The 1% rule — when to retire an inbox
A healthy inbox should have an overall reply rate of ≥1% after sending 200+ emails. Below that, it's likely burned or has poor deliverability.
To identify inboxes failing this rule:
# Run the audit to find offenders
/email-deliverability-audit → scripts/audit-performance.ts --days=30 --out=/tmp/audit/performance.csv
# Then tag the failing inboxes as retired
cat /tmp/audit/performance.csv | awk -F',' '$11 == "\"true\"" { print $1 }' > /tmp/retire-ids.txt
npx tsx scripts/tag-inboxes.ts --ids-from-csv=/tmp/retire-ids.txt --add-tag=retired --remove-tag=active
npx tsx scripts/set-warmup.ts --mode=disable --tag=retired
Common gotchas
- Warmup settings are per-inbox. There's no global setting. Scripts loop and hit each inbox individually.
- Rate-limiting. Smartlead allows ~33 req/sec. The scripts use 5 concurrent by default. Don't crank this higher without testing.
- Warmup blocked. If
is_warmup_blocked: true, the inbox is flagged (usually for spam-like behavior in warmup). Manual investigation needed. - Tags have no delete endpoint in some Smartlead versions — tags can only be ADDED. To "remove" a tag, replace the full tag list with a new one that omits it. The script handles this automatically.
- Signature formatting. HTML signatures can break rendering across Gmail/Outlook/Apple Mail. Keep it plain text or use minimal
<br>tags. Test in Gmail/Outlook after setting. - Warmup ramp accumulates. If you set
daily_rampup: 5, the inbox sends 1 on day 1, 6 on day 2, 11 on day 3... up tototal_warmup_per_day. To reset (e.g. after a break), disable then re-enable.
What to do next
If you just provisioned new inboxes: enable warmup (set-warmup.ts --mode=enable), apply signatures (set-signatures.ts), tag as insurance, then wait 2 weeks for warmup. After 2 weeks, promote insurance → active.
If inboxes are already warm: proceed to list-building (/prospeo-full-export, /disco-like, etc.) using active-tagged inboxes.
Or wait: if health dashboard shows bad-reputation inboxes, retire them first (tag retired, disable warmup) before launching a new campaign.
