Cold Email Software Price: What Moves the Number
Cold email software price here is a published monthly rate set by volume. Starter is $18/month for 2,000 emails and one SMTP slot. The number moves on three things: sends per month, contacts you store, and mailboxes you connect. Nothing else is metered.

The published monthly list, read in one pass
Six monthly plans sit on this site, and each one is a fixed rate against a send ceiling. Starter is $18/month for 2,000 emails and one SMTP slot. Growth is $38/month for 10,000 emails, a reply inbox and API keys. Scale is $78/month for 50,000 emails and bulk campaigns. Business is $198/month for 100,000 emails and two SMTP slots.
Above that, Agency is $498/month for 250,000 emails and five SMTP slots, and Enterprise is $1000/month for 500,000 emails and ten SMTP slots with a managed pool. Read the list as a ladder of send ceilings. Each rung also widens the features that surround the send: diagnostics, mailbox health, API workflows.
- Write down your send ceiling before you compare any two rows
- Count SMTP slots you actually need, not the ones you might add
- Check whether reply inbox and API keys appear on the rung you chose
- Compare the full monthly list side by side before deciding
If you want every rung in one table,the full monthly price listsets the six plans against their send ceilings and slots.
Input one: sends per month
Sends are the first lever. A campaign of 500 contacts touched four times is 2,000 emails, which fits Starter at $18/month exactly. Touch the same 500 contacts eight times and you are at 4,000 emails, which does not fit Starter. You either cut touches or move to Growth at $38/month for 10,000 emails.
The arithmetic is simple and worth doing before you buy. Multiply contacts by touches to get your monthly send figure, then find the first rung whose ceiling covers it. Do not buy on the contact count alone, because the send count is what the plan actually meters.
- Multiply contacts by planned touches to get monthly sends
- Pick the first plan whose ceiling covers that figure
- Leave room for follow-ups, which count as sends too
- Recheck the figure whenever you add a sequence step
Input two: contacts you store
Contacts are the second lever, and on this site they are not the metered unit on the monthly plans. The send ceiling is. That means a large stored list does not by itself push you up a rung; the emails you send to it do. A list of 20,000 contacts mailed once is 20,000 sends, which lands on Scale at $78/month.
This matters when you compare against the tool you are leaving, which may meter stored contacts separately. Check that vendor's current published terms rather than assuming the two bills move together. Here, a big list is only expensive when you mail it.
- Confirm whether your current vendor meters stored contacts
- Estimate sends from the segment you will actually mail
- Keep dormant contacts unmailed until a campaign needs them
- Recheck the send figure after any list import
For a per-month view that starts from volume rather than list size,monthly cost by send volumewalks the same six plans from the send side.
Input three: mailbox count and SMTP slots
Mailboxes are the third lever, and here they appear as SMTP slots. Starter carries one slot, Business two, Agency five and Enterprise ten. Growth and Scale sit between them on sends but not on slots, so a team running several sending identities should read the slot column before the send column.
A worked example. Two sending identities on separate domains need two slots, which puts you on Business at $198/month for 100,000 emails. If one identity would do, Starter at $18/month covers 2,000 sends and the second domain waits. Slots, not sends, decide that jump.
- Count distinct sending identities, not inboxes you read
- Match each identity to a domain you control
- Check the slot column before the send column
- Add slots only when a second domain is ready to send
When a lifetime licence beats a monthly plan
The monthly ladder suits volume that changes. A lifetime licence suits a fixed job. AI Sales Agent at $149 carries 2,000 managed sends a month, one sender identity and AI-written sequences, which is the Starter ceiling as a one-time price. That is worth weighing if your volume is steady and small.
The catalogue is wider than cold email, so read it narrowly. LocalSMTP at $149 gives five verified SMTP accounts with SMTP and IMAP settings. Mail Pro at $149 is a lifetime unlimited licence with warm-up on every account. Neither is a send plan; both are pieces you might otherwise rent monthly.
- Compare a lifetime licence against twelve months of the matching plan
- Check the licence's monthly send allowance, not just the price
- Treat SMTP and warm-up tools as separate purchases
- Buy a licence only when the volume is predictable
Before you commit to either shape,buying cold email softwarecovers what to confirm at checkout and what to test in week one.

What it will not do
The price list is honest about ceilings, and it is also honest about what a plan cannot fix. Buying a higher rung does not repair a weak offer, a cold domain or a list that never opted in to anything resembling your pitch.
- It will not raise a send ceiling mid-month; you change plan or wait
- It will not add SMTP slots without moving to a higher rung
- It will not guarantee inbox placement on any plan
- It will not meter stored contacts on the monthly plans, so list size alone will not show up on the bill
- It will not replace domain warm-up, which is a separate purchase
Frequently asked questions
What is the cheapest monthly plan here?
Starter at $18/month. It carries 2,000 emails a month and one SMTP slot, with AI assistance. That suits one sender mailing a small list a few times. If you need a reply inbox or API keys, the next rung is Growth at $38/month.
Do stored contacts change the price?
Not on the monthly plans. They meter sends, not stored contacts. A large list costs you only when you mail it. Check the tool you are leaving against its own published terms, because some vendors meter contacts separately and the two bills then move differently.
How do SMTP slots affect what I pay?
Slots rise with the plan. Starter has one, Business two, Agency five, Enterprise ten. Growth and Scale sit between on sends but not on slots. If you run two sending identities, you are on Business at $198/month even if your send volume is small.
Can I combine a monthly plan with a lifetime licence?
Yes, they are separate purchases. AI Sales Agent at $149 covers 2,000 managed sends a month as a one-time price, and LocalSMTP at $149 gives five verified SMTP accounts. Neither removes the need for a send plan if your volume exceeds what the licence allows.
Pick the rung your sends actually reach
Work out contacts times touches, then match that figure to the published ladder. Starter at $18/month covers 2,000 sends; Growth at $38/month covers 10,000.
