Overview
Instantly vs Smartlead at a glance
Instantly and Smartlead are the two most common cold email tools for sending at volume from many inboxes. Both price by contacts and monthly emails rather than per mailbox. Published terms, October 2026.
| Instantly | Smartlead | |
|---|---|---|
| Entry plan | Growth: $47/mo, 5,000 emails | Base: $39/mo, 6,000 emails |
| Email accounts | Unlimited, every plan | Unlimited, every plan |
| Warmup | Unlimited, every plan | Included; pool tier rises with plan |
| Inbox rotation | Unlimited accounts per campaign | Automatic across a campaign's mailboxes |
| Unified inbox | Unibox: preview on Growth, replies from Hypergrowth | Unified inbox; plan limits not published |
| API & webhooks | API on every plan; webhooks from Hypergrowth | From Pro; not on Base |
| Built-in CRM | Add-on: $47 or $97/mo | Included from Pro |
| White-label / clients | Hypergrowth and Light Speed | $29/mo per client from Pro; 3 on Prime |
| Lead database | SuperSearch, on separate credits from $9/mo | Verified prospect emails per plan |
| Free trial | 14 days, 1,000 emails, 250 contacts, no card | Yes, no card |
The short version: if you send fewer than 90,000 emails a month, Smartlead is the cheaper of the two on every tier. Between 90,000 and 125,000 emails a month, Instantly's $97 Hypergrowth plan undercuts Smartlead's $174 Unlimited Smart. At the top end the two are within $21 of each other. Features overlap heavily, so the deciding factors are usually agency workflow, whether you want a lead database in the same tool, and which interface your team likes after a trial.

Cost per 10,000 emails as your volume grows
Cheapest plan that covers the volume ÷ emails sent × 10,000, monthly billing. Example: 100,000 emails on Instantly Hypergrowth = $97 ÷ 100,000 × 10,000 = $9.70; on Smartlead it needs Unlimited Smart = $174 ÷ 100,000 × 10,000 = $17.40. At 150,000, Instantly needs Light Speed ($358), so its cost jumps to $23.87.
| Instantly, 5K | $94.00 |
|---|---|
| Instantly, 25K | $38.80 |
| Instantly, 50K | $19.40 |
| Instantly, 100K | $9.70 |

- 125,000 to 500,000: Smartlead Unlimited Smart ($174, 150,000 emails) fills the gap below Instantly Light Speed ($358). At 500,000 emails, Light Speed is $358 and Unlimited Prime $379.
Instantly's Hypergrowth email allowance
Features
Warmup, inbox rotation, agency features and API
On paper the two tools do the same job. The differences show up in which plan unlocks each feature and how add-ons are priced.
Warmup
Both include warmup at no extra cost. Instantly lists unlimited warmup on every plan. Smartlead includes it too, but the warmup pool you join depends on your plan: Foundation on Base, Growth on Pro and Premium on the two Unlimited plans. Warmup builds sending history; it doesn't replace authentication or sensible volume. More in the email warmup guide.
Inbox rotation
Both spread a campaign's sends across every mailbox you attach to it. Instantly says you can assign unlimited sending accounts to a single campaign and rotates between them; Smartlead rotates across all connected mailboxes in a campaign automatically. Since neither charges per mailbox, adding inboxes costs nothing on the tool side; the cost is the mailboxes themselves.
Agency and white-label
Instantly includes a white-label client portal on Hypergrowth and Light Speed: clients log in on your own subdomain with your logo, and its help center mentions no per-client fee. Separate Instantly workspaces each need their own subscription. Smartlead sells client workspaces with white-label branding for $29 a month each from Pro upwards, and Unlimited Prime includes 3.
API, webhooks and CRM
Instantly includes API access on every plan and adds webhooks from Hypergrowth; its CRM is a separate add-on at $47 or $97 a month. Smartlead Base has no API, webhooks or CRM access; all three arrive with Pro.
Leads and mailboxes inside the tool
Instantly's lead database, SuperSearch, runs on separate credits from $9 a month for 150 credits. Smartlead includes a monthly allowance of verified prospect emails on each plan, as a $59 add-on on Base and Pro. Both also sell mailboxes in the app. Instantly's done-for-you Google accounts are $5 a month each with domains at $15 a year, and Instantly keeps ownership of those domains. Smartlead's SmartSenders resells Google and Outlook mailboxes from $4.50 a month plus $13 a domain a year.
Whichever tool you pick, it needs mailboxes
Jetmail sets up Google and Microsoft mailboxes on domains you own, with SPF, DKIM and DMARC, and connects them to Instantly or Smartlead.
Verdict

Still undecided? Run the same campaign on each free trial with the same mailboxes and compare the workflow, not just the price. For the wider field, including lemlist, Apollo and Reply.io, see best cold email software and lemlist alternatives.
Setup
Switching between Instantly and Smartlead with your own mailboxes
The sending tool is the easy part to change. Mailboxes, domains and their reputation are the hard part, so keep them independent of the tool. A plan's email allowance needs enough mailboxes to send it safely. At about 30 cold emails per mailbox a day over 22 sending days (Jetmail's planning assumption):
| Plan allowance | Emails / month | Mailboxes needed | Domains | Jetmail / month* |
|---|---|---|---|---|
| Instantly Growth | 5,000 | 8 | 3 | $39 |
| Smartlead Base | 6,000 | 10 | 4 | $39 |
| Smartlead Pro | 90,000 | 137 | 46 | $410 |
| Instantly Hypergrowth | 125,000 | 190 | 64 | $569 |
| Smartlead Unlimited Smart | 150,000 | 228 | 76 | $683 |
*Standard Jetmail mailboxes, cheapest plan for that count, billed monthly. Domains billed separately. 3 mailboxes per domain.
