A Low Cost Cold Email Platform Measured Per 1,000 Emails
Cost per 1,000 emails divides a plan's monthly price by its included volume, times one thousand. On the published plans that figure falls as you move up tiers: Starter costs more per thousand than Growth, and Growth more than Scale. A low monthly price is not the same as a low unit cost.

How to Work Out Cost Per 1,000 Delivered Emails
Take the monthly price, divide by the included send volume, then multiply by one thousand. Starter at $18/month includes 2,000 emails, so each thousand costs nine times the monthly price divided by eighteen. Do the same sum for Growth at $38/month with 10,000 emails and the per-thousand figure drops sharply, because the volume grows faster than the price.
This is the only honest way to compare a low cost cold email platform. A plan that looks small on the invoice can carry the highest unit cost, and a plan that looks large can be the cheaper place to send the same number of emails. Run the sum on your own monthly volume before you choose a tier.
- Write down your monthly send volume first, not your budget
- Divide each plan price by its included emails
- Multiply by one thousand for the unit figure
- Recheck the sum at your busiest month, not your average
If the per-thousand figure is your main filter, start withcheap cold email softwareand compare plans on volume rather than sticker price.
Where a Low Monthly Price Stops Being Low
Starter at $18/month covers 2,000 emails. If you actually send 10,000 a month, you either buy Growth at $38/month or you stay on Starter and run out early. Staying low means sending less, not paying less for the same work. The plan did not get expensive; your volume outgrew it.
The same step repeats further up. Scale at $78/month covers 50,000 emails. Business at $198/month covers 100,000. Each tier raises the price, but it raises the included volume by more, so the cost per thousand keeps falling. The break point is where your volume sits, not where the price looks comfortable.
- Find the tier whose included volume sits just above your real send count
- Treat a plan you outgrow as a signal to move up, not to throttle
- Compare two adjacent tiers at your own volume before switching
- Recalculate after any list growth, since the tier you fit changes
Sending volume also depends on how many SMTP slots you hold, which is whycheapest cold email software with SMTPis worth reading alongside this page.
A Worked Example at 50,000 Emails a Month
Suppose you send 50,000 emails a month. Scale at $78/month includes exactly that volume, so you pay the plan price once and the cost per thousand is the plan price divided by fifty. Agency at $498/month includes 250,000 emails, five times the volume of Scale, and costs more than six times as much, so at 50,000 sends Scale is the lower unit cost of the two.
Now suppose you send 250,000 a month. Scale covers 50,000, so you would need five of those plans to match the volume, and five $78/month plans cost more than one Agency plan at $498/month. The unit cost flips. This is the whole argument: the cheap plan is cheap only at the volume it was built for.
- Multiply the smaller plan by the number of copies you would need
- Compare that figure with the single larger plan price
- Check whether the larger tier includes the SMTP slots you need
- Confirm the included volume in writing before you commit
Reading the Tier List Against Your Own Numbers
The published plans run from Starter at $18/month with 2,000 emails to Enterprise at $1000/month with 500,000 emails and ten SMTP slots. Every tier between them raises volume by more than it raises price, which is why the per-thousand figure falls as you climb. None of them is a trick; they are priced for different send counts.
The mistake is buying the lowest tier and expecting the unit cost of the highest. If your list is small, Starter or Growth is genuinely the low cost cold email platform for you. If your list is large, the low monthly price is a false economy and the higher tier is the cheaper way to send.
- Match the tier to your list size, not to your first invoice
- Check included SMTP slots if you send from several domains
- Note that Business and above add diagnostics and API workflows
- Ask what happens when you exceed the included volume
Once the per-thousand sum points to a tier,buy cold email softwaresets out what the purchase actually includes.
Volume Changes the Answer, Not the Price List
Prices here are published and fixed. What changes is which one applies to you. A reader sending 2,000 emails a month and a reader sending 250,000 are looking at the same table and reaching opposite conclusions, and both are correct for their own volume. That is why the per-thousand figure matters more than the headline number.
Before you commit, write your monthly send count on paper and run the division for two or three tiers. The result tells you where your volume sits and which plan is genuinely low cost for you. It takes a few minutes and it replaces guesswork with arithmetic.
- Use last month's actual send count, not a forecast
- Run the sum for the tier above yours as well
- Revisit the sum whenever your list grows
- Keep the included volume and price in your own notes

What it will not do
The published plans price sending volume and SMTP capacity. They do not lower the cost per thousand for you, and they do not make a small plan cheap at a large volume. Read these before you assume the entry tier will carry a growing list.
- It will not keep your unit cost low if you send far above your tier's included volume
- It will not add SMTP slots beyond the number published for your plan
- It will not convert your volume into a discount or a custom rate
- It will not guarantee placement in an inbox at any price
- It will not stop your per-thousand figure rising if you stay on a tier you have outgrown
Frequently asked questions
Is the cheapest monthly plan always the lowest cost per email?
No. Starter at $18/month includes 2,000 emails, so its cost per thousand is high relative to larger tiers. The lowest unit cost comes from the tier whose included volume sits closest above your real send count, not from the smallest invoice.
How do I work out cost per 1,000 emails myself?
Divide the monthly price by the included email volume, then multiply by one thousand. For Scale at $78/month with 50,000 emails, the plan price divided by fifty gives the per-thousand figure. Use your own send count to decide which tier to test.
What happens if I send more than my plan includes?
Your volume exceeds the tier you bought, so you either move up to the next published plan or send less. The plans do not convert excess volume into a lower rate, and no discount is published for exceeding the included amount.
Do the same sums apply to lifetime deals?
No. Lifetime deals are one-time prices sold elsewhere and priced on different inclusions. This page compares the monthly plans only. If you want a one-time licence, check the published lifetime terms and note that code SALE20 takes 15% off them.
Run the Division, Then Pick the Tier
Write your monthly send count down, divide each published price by its included volume, and choose the tier that fits. Growth at $38/month covers 10,000 emails when your list has outgrown Starter.
