How many cold emails should I send?

Work backwards from your revenue target. If your average deal is $5,000 and close rate from meeting is 25%, you need 4 meetings per deal. At a 3% meeting rate per email, you need ~133 emails per deal closed.

Does email list size affect deliverability?

Sending volume affects sender reputation. Keep daily sending volume under 500 emails per domain (100 for new domains). Warm up new domains over 4–8 weeks. Use email verification to remove invalid addresses before sending.

What is a good cold email open rate?

A 30–45% open rate is strong for B2B cold email. Below 20% suggests a subject line or deliverability problem. Open rates have become less reliable since Apple's Mail Privacy Protection (MPP) which pre-loads tracking pixels.

How do I improve cold email reply rates?

Key levers: (1) personalize the first line with specific research about the prospect, (2) lead with a problem they have rather than your product, (3) short emails (under 100 words) outperform long ones, (4) include a clear, low-friction CTA.

How is cold email ROI calculated?

Multiply list size through each funnel stage — opens, replies, meetings, closed deals — then multiply closed deals by average deal value for projected revenue. ROI = (revenue − campaign cost) ÷ campaign cost × 100. A small lift in reply rate compounds through the entire funnel.

Is my data sent to a server?

No. The cold email forecast runs entirely in your browser with JavaScript. No campaign figures, list sizes, or revenue numbers are uploaded, logged, or stored anywhere.

Troubleshooting

How to fix common syntax errors

Most “invalid JSON” failures come from a small set of mistakes. Paste the failing JSON above, click Validate, and the tool points you at the exact line and column.

Treating open rate as the primary success metricopenRate = 60%, but replies = 0.5%

Open tracking is unreliable since Apple MPP pre-loads pixels. Use reply rate as the ground-truth metric — it cannot be faked.

Sending too many emails per day from a new inbox200 emails/day from 1-week-old domain

New inboxes should send 20–50/day and ramp over 4–8 weeks. High volume from cold domains triggers spam filters and kills deliverability.

Including unverified addresses in list sizelistSize = 5,000 unverified contacts

Remove invalid and catch-all addresses before forecasting. 10–20% of most lists are undeliverable; sending to them burns your sender reputation.

Single email with no follow-up sequence1 email sent, no follow-ups

Most replies come on follow-up 2 or 3. A 3–5 step sequence is 2–3× more effective than a single send.

Applying meeting rate to all replies, not positive repliesmeetingRate applied to total replies = 15%

Meeting rate should apply only to positive/interested replies. Applying it to all replies overestimates meetings — positive replies are typically 30–50% of total replies.

Understating campaign costcost = list purchase price only

Include tool subscriptions (sequencer, verifier, enrichment), copywriting time, and rep time. Total campaign cost is often 2–3× the list cost alone.
