Volume calculator — how much to send to hit your MQL target.

Set your goal. The math updates live. It’s the same back-of-napkin work I do in every first call — just exposed as sliders so you can run it yourself.

Target MQLs per month 10

3 15 30 50

An MQL here = positive reply that books a first-call slot.

Your ACV $25K

$5K $25K $50K $100K+

Used to size the opportunity alongside cost-per-MQL.

Reply rate you can realistically hit 2.0%

0.5% 2% 3.5% 5%

Assume "positive" replies only. 2–3.5% is typical for signal-based outbound.

Positive-reply → booked-meeting rate 30%

15% 30% 45% 60%

Of positive replies, how many actually book. 25–35% is typical with prompt follow-up.

Sending discipline

35/day keeps you well under Google’s throttle threshold. 45/day starts flirting with it.

0 contacts/month you need to send to hit the target.

Weekly sends

Split across your inboxes

Daily sends

Across business days

Inboxes needed

With discipline headroom

Domains needed

3 inboxes per domain

Target MQLs/month 10

÷ Positive-reply → meeting rate 30%

= Positive replies needed/month 0

÷ Positive-reply rate 2.0%

Contacts/month needed 0

Caveats: This assumes every lever above is running clean — deliverability at 95%+, ICP narrow enough to personalize, sourcing freshness under 60 days. If any of those are broken, add 30–50% to the contacts/month number and plan for a 6–8 week ramp.

Like the numbers? Let’s see if the ICP is deep enough.

The calculator tells you how many contacts to send. The TAM mapper tells you whether those contacts actually exist. Both are wired up from the same ICP definition.
