The first 2 weeks we're building infrastructure and testing messaging. Then we need time to warm up domains properly and optimize based on real response data. By day 30–45 you're getting consistent meetings, and by day 120 the system is fully matured and performing at peak.

What do you need from our team?

Access to your CRM for meeting bookings, 1–2 hours upfront for ICP definition, and a point person for meeting coordination. We handle everything else—the data, the emails, the infrastructure, the optimization.

Will this hurt our email deliverability?

No. We use dedicated sending infrastructure completely separate from your company domain. If anything goes wrong (rare), it affects our systems, not yours.

What if we don't get results?

We show early indicators by day 30 (reply rates, positive responses). If the data suggests it's not working, we pivot strategy or part ways—no 12-month lock-in.

What happens after 120 days?

Most clients continue on a monthly retainer because we're still delivering meetings. Some bring it in-house (we'll train your team). You decide based on ROI.

The Email Volume Formula

Cold email volume isn't arbitrary. There's a formula:

Daily Capacity = Domains × Inboxes per Domain × Emails per Inbox

Safe limits:

Emails per inbox: 30-40/day (never exceed 50)
Inboxes per domain: 2-3 (more risks domain reputation)
Warmup period: 14 days minimum before full volume

Example:

You want to send 300 emails/day.

300 ÷ 35 (avg per inbox) = 8.6 inboxes needed 8.6 ÷ 2.5 (inboxes per domain) = 3.4 domains

Round up: 4 domains, 2-3 inboxes each = 10 inboxes = 350 emails/day capacity

Buffer matters. You want 15-20% extra capacity for warmup rotation and recovery.

What This Means For Revenue

Here's the executive summary:

Daily Volume	Expected Meetings/Month	Pipeline (at $15K deal)
100 emails	3-5	$45K-$75K
300 emails	9-15	$135K-$225K
500 emails	15-25	$225K-$375K
1,000 emails	30-50	$450K-$750K

These assume 3% reply rate, 50% meeting rate—our client averages.

The infrastructure below is what makes those numbers happen.

Infrastructure Breakdown

Domains

Why secondary domains: Never send from your main domain. One spam complaint and you've destroyed your primary business email.

Domain naming patterns:

getbuzzlead.com
trybuzzlead.com
buzzleadhq.com
withbuzzlead.com
buzzleadteam.com

Keep them professional. Match your brand. Avoid weird TLDs.

Cost per domain:

.com: $12-15/year
.io: $30-50/year
.co: $25-30/year

The domain formula:

Domains Needed = (Daily Volume ÷ 30) × 1.5

That 1.5x multiplier accounts for warmup rotation and recovery domains.

Inboxes

Google Workspace vs. Outlook: Both work. Google has slightly better deliverability. Outlook is cheaper for high volume.

We use a 70/30 Google/Outlook split for most clients.

Cost per inbox:

Google Workspace: $6-12/month
Microsoft 365: $6-12/month

Setup time:

Creating accounts: 30 min per domain
DNS configuration: 15 min per domain
SPF/DKIM/DMARC: 20 min per domain

Warmup

New inboxes can't send at full volume immediately. They have no reputation.

Warmup schedule:

Days	Emails/Day
1-3	5
4-7	10
8-10	20
11-14	30
15+	Full capacity

Warmup tools: We use the built-in warmup in SmartLead and Instantly. Both work. Cost is included in platform pricing.

The 75% rule: Monitor inbox placement weekly. If you drop below 75% inbox rate, pause immediately. Fix the issue. Retest. Resume.

47 meetings booked
$520K in immediate pipeline

Common Volume Mistakes

1. Sending Too Much, Too Fast

You bought 10 domains. Set up 30 inboxes. Immediately sent 1,000 emails.

Result: 40% landed in spam. Domains burned. Months of recovery.

Fix: Follow the warmup schedule. No exceptions.

2. Too Few Domains

You're trying to send 300/day from 2 domains.

Result: Each domain is sending 150/day. That's suspicious volume. Reputation tanks.

Fix: More domains = lower volume per domain = better deliverability.

3. Ignoring the Buffer

You calculated exactly 10 inboxes for your volume. You set up exactly 10 inboxes.

Result: When one inbox has issues, you're under-capacity. No room to rotate.

Fix: 15-20% buffer. Always.

4. Chasing the Cheapest Domains

You saved $50 by buying domains with obscure TLDs.

Result: Lower deliverability out of the gate. Some email providers filter unusual extensions more aggressively.

Fix: .com is worth the premium. Professional-looking domains build trust.

Sending Platform Selection

Your volume determines your platform:

Volume	Platform	Why
< 500/day	SmartLead	Best all-in-one for SMB
500-2,000/day	Instantly	Scales affordably
2,000+/day	Email Bison	Enterprise features

SmartLead: $39/mo. Includes warmup. Unlimited inboxes.

Instantly: $37/mo. Good analytics. Easy setup.

Email Bison: Custom pricing. Private IPs. White-glove support.

We use Email Bison internally. For most clients starting out, SmartLead is the right call.

How many cold emails can I send per day safely? 30-40 per inbox. With 10 inboxes across 4 domains, that's 300-400 emails/day at safe limits. Push past this and you risk deliverability issues.

How many domains do I need for cold email? Use the formula: (Daily Volume ÷ 30) × 1.5. For 300 emails/day, that's about 15 domains. The 1.5 multiplier gives you buffer for warmup and rotation.

What's the cheapest way to scale cold email volume? Look for domain deals, but don't sacrifice professionalism. Use Google Workspace at $6/user. Run warmup through your sending platform (included). Total infrastructure cost: ~$200/month for 500 emails/day capacity.

How long does it take to warm up new email accounts? 14 days minimum. Start at 5 emails/day, ramp to 30-40 by day 15. Rushing warmup is the #1 cause of new account burnout.

Should I use Google or Outlook for cold email? Both work. Google Workspace has slightly better deliverability. Outlook is cheaper at scale. We recommend a 70/30 split for diversification.
