Smartlead's 'Unlimited' Plans Cap Your Sends — Unlimited Is the Contacts, Not the Emails

Four plans, and the naming does real work:

The word "Unlimited" attaches to the contact count. The sends — the thing a cold email campaign consumes — are capped on every plan without exception.

That is not hidden; the numbers are printed on the same page. But a plan called Unlimited Smart sets an expectation the send column then corrects, and the correction is the one that determines whether the plan fits.

Base's $39 looks like the obvious starting point. Convert it into daily reality:

6,000 sends ÷ 30 days = 200 emails a day, across all your mailboxes combined.

Cold email works on volume and sequencing. A three-touch sequence means each prospect consumes three sends, so 6,000 sends is 2,000 prospects a month fully sequenced — which is also exactly Base's contact limit. The two numbers are matched deliberately, and that is coherent design: Base is sized for one small campaign at a time.

What it is not sized for is testing. Running two subject-line variants against a list, then a follow-up sequence to non-openers, exhausts the month quickly. If you plan to iterate rather than send once, Base is a single-campaign plan, not a starter plan.

Pro at $94 gives 90,000 sends — a 15× jump for 2.4× the price, and the point where the platform starts behaving like infrastructure rather than a trial.

Each plan lists a verification allowance that does not match the send allowance:

• Base: 2,000 verified of 6,000 sends
• Pro: 30,000 of 90,000
• Unlimited Smart: 50,000 of 150,000
• Unlimited Prime: 170,000 of 500,000

Verification is what keeps a list from burning your sending domain, and on the top three plans the verification budget covers about a third of the sends.

That ratio is defensible — you verify a contact once and email them three times — but it means the allowances are only in balance if your sequences are around three touches. Run longer sequences and verification is ample; run single-touch blasts to fresh lists and verification, not sends, is your ceiling. The pricing page states verification credits can be purchased separately, without stating the price.

Three published add-ons, none included:

• Whitelabeling — $29/month per client workspace
• SmartServers — $39/server/month
• Email verification — priced by credits purchased (amount not stated)

Whitelabeling is the one to model carefully, because it is priced per client workspace rather than per account. An agency running the platform under its own brand for eight clients is $232/month in whitelabeling alone, on top of a plan.

At that point Unlimited Prime at $379 is worth a second look: it lists 3 SmartServers with OAuth and 3+ client workspaces included, which absorbs some of what the add-ons would otherwise cost separately. Whether it comes out ahead depends entirely on client count — but the comparison is plan-plus-add-ons versus plan-plus-add-ons, and never the two headline prices.

A previous version of this page stated that unlimited mailboxes were included on all plans.

Smartlead's pricing page does not state a mailbox or email-account allowance at all — not on any tier. That claim has been removed rather than corrected downward, because the honest position is that the number is unpublished.

If mailbox count is central to your setup — and for cold outreach at volume it usually is, since sends are spread across many sending addresses to protect deliverability — get it confirmed in writing before subscribing. It is the one figure this pricing page does not give you, and it is not a small one.

Everything above is arithmetic. The thing that decides whether a cold email tool is worth anything is whether the mail arrives, and no pricing page can tell you that.

Smartlead's warmup pooling — Premium on Unlimited Smart, with Ultrapremium eligibility, and SmartServers with OAuth on Prime — is aimed squarely at this, and it is the reason to pay for the upper tiers rather than the send counts. It is also unverifiable from the outside. Deliverability depends on your domains, your list quality and your copy at least as much as the platform, and any review claiming to have measured a vendor's inbox rate in general is describing one setup, not a property of the tool.

If you have not confirmed cold email is legal and appropriate for your market and list, the tooling question is premature. Consent rules differ sharply by jurisdiction, and a platform that sends efficiently makes a compliance mistake efficient too.

If your list is a few hundred people you already know, this is the wrong shape of tool. Sequencing infrastructure exists to solve volume, and at small scale it adds machinery to a job that a normal email client and a spreadsheet do without a subscription.

Base at $39 is a real entry price and the allowances are all published, which is more transparency than parts of this category offer.

But price it on the sends column and treat the plan names as marketing. 6,000 sends is 200 a day; "Unlimited" means contacts; whitelabeling is $29 per client workspace on top; and the mailbox count — the number that matters most for deliverability — is not on the page at all.

All plan prices, the 17% annual discount, contact, send and verification allowances, whitelabeling at $29/month per client workspace, SmartServers at $39/server/month, and the warmup pool tiers are from Smartlead's own pricing page, checked 10 August 2026. Email account and mailbox allowances are not stated on that page.
