Overview

What Smartlead is

Smartlead is a cold email sequencer. You connect as many Google, Outlook or SMTP mailboxes as you like, it warms them up, rotates sending across a campaign's mailboxes and collects replies in one master inbox. Around that it sells add-ons: verified prospect emails (SmartProspect), placement tests (SmartDelivery), dedicated servers, white-label client workspaces and a dialer.

The company behind it is 521 Products Pty Ltd, ACN 645 593 835, an Australian registered business that trades under the Smartlead and SmartProspect brands. Its terms are governed by New South Wales law, and its data processing addendum covers GDPR with EU standard contractual clauses.

Smartlead says it is used by more than 100,000 businesses. On Trustpilot the picture is split: a 2.9 score from 142 reviews, with about as many one-star as five-star ratings.

Add-ons and extra costs

Base at $39 is a test plan: 6,000 sends and 2,000 contacts a month, with no API, webhooks or team members. Pro at $94 adds the API and 90,000 sends; Unlimited Smart at $174 removes the contact cap and adds 150,000 sends. The full plan list with every slider step is in our Smartlead pricing breakdown.

Between Smart and Prime the pricing page has a plan slider: 240,000 sends cost $228 a month, 330,000 cost $282. Annual billing takes about 17% off, and new subscriptions can be refunded within 7 days.

Add-ons are where the bill grows: verified emails are $59 a month on Base and Pro, SmartServers $39 per server, placement tests from $49 and white-label workspaces $29 each.

25 cold emails per mailbox a day and 5 mailboxes per domain: 1,000 a day = 40 mailboxes, 8 domains, 22,000 emails a month; 5,000 a day = 200 mailboxes, 40 domains, 110,000 emails a month; 10,000 a day = 400 mailboxes, 80 domains, 220,000 emails a month (22 sending days). Monthly list prices on monthly billing; .com domains at $13 a year spread over 12 months.

Why each Smartlead plan

At 1,000 emails a day Pro covers the volume, so Smartlead is $94 of a $203 setup with our mailboxes. At 5,000 a day the 110,000 sends a month need Unlimited Smart, and at 10,000 the 240,000 slider step: $717 and $1,315 with Outreach2day mailboxes.

SmartSenders Google inboxes cost $4.50 each, so 200 of them are $900 a month against $500 for ours. They also work only inside Smartlead and their domains expire after a fixed 12 months with no renewal.

Outreach2day all-in drops the Smartlead plan: mailboxes, warmup and our sequencer in one bill, $543 a month at 5,000 emails a day. That fits email-only campaigns; Smartlead keeps the edge on add-ons like the dialer and client workspaces.

In detail

Is Smartlead legit?

Yes. Smartlead is run by 521 Products Pty Ltd (ACN 645 593 835), registered in Australia, with support at support@smartlead.ai. Its privacy policy lists data hosting in Australia, Singapore, India, Japan, the United States, Canada, Germany, Ireland and Sweden.

The Trustpilot score is low for a tool this size, 2.9 from 142 reviews, and the reviews split into very good and very bad. The terms you can check before paying: a 7-day refund on a new subscription, non-refundable add-ons, and SmartSenders mailboxes that stay inside Smartlead.

Smartlead vs Instantly

Both connect unlimited mailboxes with warmup and price by emails and contacts. Smartlead Pro is $94 for 90,000 sends and 30,000 contacts; Instantly Hypergrowth is $97 for 125,000 emails and 25,000 contacts. Smartlead keeps the API off Base and refunds new subscriptions within 7 days; Instantly has the API on every plan and refunds nothing.

At 5,000 emails a day with the same 200 Outreach2day mailboxes the two cost $717 and $727 a month, so the choice comes down to features and terms. Every line is in Instantly vs Smartlead.

API, MCP and our mailboxes in Smartlead

The API and webhooks start on Pro. Smartlead runs an official MCP server at mcp.smartlead.ai over SSE with your API key, so an assistant like Claude can read campaigns, leads and stats; our Smartlead MCP comparison sets its tools next to ours.

Outreach2day connects to Smartlead with an API key: warm mailboxes are added to your Smartlead account and reconnected if they drop (how the export works).
