Cheapest Cold Email Software by Real Monthly Cost

The cheapest cold email software in 2026 is Saleshandy once you count the mailboxes you have to buy. Its Starter plan is $34 a month on annual billing ($41 monthly) for 2,000 active prospects and 6,000 emails a month, and it sells sending mailboxes from $2.99 each. Smartlead has the lowest plan card at $32.50 a month annual ($39 monthly), but its mailboxes cost $4.50 each, so ten of them put it about $13 a month behind. GMass is cheaper still on paper at $249 a year, but that plan has no follow-up sequences.

We read every price below on the vendor's own pricing page in October 2026, from US-dollar pricing. Cold email pricing changes often, so treat this as a snapshot and confirm the figure at checkout. The point of this page is the method, which stays useful after the numbers move: compare the whole monthly bill for the volume you will actually send, not the cheapest plan card.

Cheapest cold email software by entry price

This is the number most roundups stop at. It tells you what the smallest paid plan costs, and almost nothing about what you will pay once a campaign is running.

What does cold email software really cost per month?

To compare like for like, price one realistic setup: a founder or a single SDR sending a three-step sequence to 2,000 prospects a month. That is about 6,000 emails. At a safe 30 emails a day per mailbox, it needs roughly 10 sending mailboxes spread over 4 secondary domains. Here is the monthly bill on annual billing, using the tool's own mailbox prices where it sells them.

Two things jump out. First, the ranking changes once mailboxes go in. Smartlead's plan card is $1.50 cheaper than Saleshandy's, and its bill is $13.26 more, because Smartlead resells mailboxes at $4.50 while Saleshandy sells them from $2.99 on an annual fixed term. If you size your domains and mailboxes first, you will know which number dominates your bill. Second, several of the cheapest-looking plans do not fit this volume at all. Instantly Growth stops at 5,000 emails, Mailshake Starter at 1,500 sends from one address, and GMass Standard cannot send follow-ups.

What is the cheapest cold email software for a solo founder?

For a solo founder sending under 6,000 emails a month, Saleshandy Starter is the cheapest complete setup at about $69 a month all in on annual billing, with warm-up, rotation and 1,500 lead credits a month included. If you already pay for Google Workspace mailboxes and only send from Gmail, GMass Premium at $349 a year is cheaper, with sequences but no inbox rotation.

The catch with Saleshandy Starter is the single seat and the 2,000 active prospect limit. The moment a second person needs access, the next plan is Pro at $76 a month annual for 10 users, 30,000 active prospects and 100,000 emails. Our Saleshandy pricing breakdown walks through each tier.

What is the cheapest cold email software for agencies and high volume?

At agency volume the per-email cost matters more than the entry price. Instantly Hypergrowth sends 125,000 emails a month for $77.60 annually, which is well under a tenth of a cent per email, with unlimited mailboxes. Saleshandy Pro sends 100,000 for $76 with 10 users. Smartlead's higher tiers add white label and client workspaces, which is why agencies reselling outbound often pay more for it. The Saleshandy vs Smartlead comparison covers that trade in detail.

Is cheap cold email software worth it?

Cheap software is worth it when the expensive part of your outbound is already handled: a verified list, warmed mailboxes on separate domains and copy that earns replies. It is not worth it when it pushes you to skip those, because a burned domain costs more to replace than a year of any plan on this page. Spend the savings on mailboxes and verification, not on more volume.

The other hidden cost is time. Every tool above sends what you write. If you are writing 2,000 personalized openers by hand, a $34 plan is buying you a much bigger job, and that labor is the line that usually decides what each meeting really costs.

How much should cold email software cost?

For one sender at a few thousand emails a month, expect to pay $35 to $85 a month for the software and another $30 to $50 for 10 mailboxes and their domains, so roughly $70 to $130 all in. Teams of three to five usually land between $150 and $400 a month. Per-seat tools climb fastest as you hire, flat per-workspace tools stay put.

Most founders pay for these tools on a company card and stop looking at the total after the first month. If you want to see what the outbound stack actually costs over a quarter, turning the card statement into a spreadsheet and filtering for the vendors on this page takes a few minutes and usually finds a forgotten mailbox subscription or two.

What is the cheapest way to send cold emails?

The cheapest safe way is a low-cost sender with unlimited mailboxes, plus mailboxes bought at the lowest per-inbox rate you can find, around $3 to $5 each. Send no more than 30 to 50 emails a day per mailbox, verify every address first, and keep sequences to three or four steps. Sending from your main Google Workspace domain is cheaper still, and it is the one shortcut that can cost you your company email.

Cheapest is not the same as cheapest per reply

Every price on this page buys a sending engine. None of the low-cost plans research a prospect and write the email for them, and that is where reply rate is won. AutoMail is not the cheapest line in the first table. It costs $24 a month on annual Starter or $49 on Growth, flat per workspace with unlimited seats, and it does the part the others leave to you: it reads each company, writes the opener and every follow-up for that prospect, sends from your warmed and rotated inboxes, stops the thread on reply and routes interested prospects to your booking link. If two cheaper tools would leave you writing every email yourself, compare on cost per reply. See AutoMail pricing or the full cold email software pricing comparison across the category.
