Pick Instantly if you want the easiest cold email tool with a big built in lead database, unlimited inbox placement tests and a white label client portal on its $97 Hypergrowth plan. Pick Smartlead if you are an agency that needs each client in its own workspace for $29 a month, or you want verified leads bundled into the plan price from Unlimited Smart ($174) up. Both include unlimited email accounts and unlimited warmup on every plan. Entry prices are close: $47 a month for Instantly Growth against $39 for Smartlead Base, but both entry plans leave out things most teams need, such as webhooks on Instantly and API, CRM and client workspaces on Smartlead.
Prices and features checked on each vendor’s own site on 19 October 2026. Neither vendor paid for or reviewed this article.
What is the difference between Instantly and Smartlead?
Both are cold email platforms. You connect as many sending mailboxes as you like, both tools warm them up, rotate sends across them and put every reply into one inbox. Neither charges per mailbox or per seat for sending, which is why both are popular with recruiters and agencies who send from dozens of domains.
Instantly is built as an all in one sales platform. On top of sending, it sells a 450M+ contact lead database (SuperSearch), a built in CRM with calls and SMS, and AI agents that write and reply for you. Lead data and AI run on a separate “Instantly Credits” subscription. The Instantly homepage says 50,000+ sales teams use it.
Smartlead is built around agencies and deliverability. Its plans are priced by send volume, include verified leads from its SmartProspect database, and add client workspaces, white label and dedicated sending servers as paid add ons. The Smartlead homepage says more than 100,000 businesses use it.

How much do Instantly and Smartlead cost in 2026?
Here are the published sending plans. Instantly takes 20% off for yearly billing on its outreach plans. Smartlead takes about 17% off.
| Plan | Monthly | Yearly billing (per month) | Emails a month | Contacts |
|---|---|---|---|---|
| Instantly Growth | $47 | $37.60 | 5,000 | 1,000 |
| Instantly Hypergrowth | $97 | $77.60 | 100,000 or 125,000 (see below) | 25,000 |
| Instantly Light Speed | $358 | $286.30 | 500,000 | 100,000 |
| Instantly Enterprise | Quote only | Quote only | 500,000+ | 100,000+ |
| Smartlead Base | $39 | $32.50 | 6,000 | 2,000 |
| Smartlead Pro | $94 | $78.30 | 90,000 | 30,000 |
| Smartlead Unlimited Smart | $174 | $144.50 | 150,000 | Unlimited |
| Smartlead Unlimited Prime | $379 | $314.60 | 500,000 | Unlimited |
Check both before you buy: the Instantly pricing page and the Smartlead pricing page. Smartlead’s yearly rates come from its pricing file, dated 28 July 2026. The live page rounds them to $32, $78, $144 and $315.
How many emails does Instantly Hypergrowth really include?
It depends which Instantly page you read. The Hypergrowth plan card and Instantly’s pricing file say 125,000 emails a month. The feature comparison table on the same pricing page, and the Scale bundle, say 100,000. Ask Instantly to confirm the limit in writing if you plan to send more than 100,000 a month on that plan.
What add ons are not in the sticker price?
This is where the two tools differ most. Instantly sells lead data and AI as a second subscription. Smartlead sells agency and infrastructure features as add ons.
| Add on | Instantly | Smartlead |
|---|---|---|
| Lead data | Credits: $9 (150), $47 (1,500), $97 (5,000), from $197 (10,000+) | $59 a month on Base and Pro; included on Unlimited plans |
| Extra volume | $87 a month for 125,000 more emails and 25,000 more contacts | Move up a plan |
| Client workspaces | Each workspace needs its own subscription | $29 a month each, from Pro |
| Dedicated servers | SISR included on Light Speed | $39 per server a month; 3 included on Prime |
| Inbox placement testing | Included | $49, $174 or $599 a month |
| Email verification | Separate verification product; price not on the pricing page | Credit packs from $32 |
| Done for you mailboxes | $4 to $10 per mailbox a month, domains $15 a year | $3.99 to $9 per mailbox a month, domains $13 to $19 a year |
One Instantly gotcha: per its pricing file, unused credits expire 2 months after purchase on monthly plans, or 1 year after on yearly plans. One Smartlead gotcha: the homepage promises “unlimited leads” with “no storage fees”, but Base caps you at 2,000 stored contacts and Pro at 30,000. Only the two Unlimited plans remove the cap.
What does each one cost per year by team size?
This is a Work Insiders calculation from the published yearly rates above, using the cheapest plan that covers each setup. Smartlead workspace add ons are counted at $29 a month, since no yearly discount is published for them. Lead data is left out.
| Setup | Instantly (yearly) | Smartlead (yearly) | Cheaper |
|---|---|---|---|
| Solo recruiter, 5,000 emails a month | $451.20 (Growth) | $390 (Base) | Smartlead by $61.20 |
| Small desk, 50,000 emails, needs inbox replies and webhooks | $931.20 (Hypergrowth) | $939.60 (Pro) | Instantly by $8.40 |
| Agency, 3 clients kept fully separate, 120,000 emails total | $2,793.60 (3 Hypergrowth workspaces) | $2,778 (Unlimited Smart plus 3 workspaces) | Smartlead by $15.60 |
| Agency, 5 clients, 400,000 emails total | $3,435.60 (Light Speed, one workspace and client portal) | $4,471.20 (Prime plus 2 extra workspaces) | Instantly by $1,035.60 |
The last row comes with a catch. Instantly’s portal puts all five clients in one workspace, and its white label docs say clients with campaign access see every campaign in that workspace. If clients must not see each other, you need one Instantly workspace per client, each with its own subscription, and Smartlead becomes the cheaper option.
Which is better for agencies managing clients?
Smartlead, for most agencies with more than a couple of clients. Each client gets its own workspace for $29 a month, and the Master Inbox page describes white labeled client dashboards, reply assignment to teammates and internal notes. Prime includes 3 client workspaces, a dedicated manager and a private Slack channel.
Instantly’s agency setup is cheaper if your clients can share a view. On Hypergrowth and Light Speed you can add unlimited client logins to a branded portal on your own subdomain, and choose whether each client sees campaigns, Unibox, analytics, CRM or the blocklist. But you cannot limit a client to their own campaigns, and the workspace docs confirm each separate workspace needs its own paid plan. Inviting team members also needs Hypergrowth or above.
Can I run my agency on the entry plans?
Not really, on either tool. Smartlead Base has no CRM, no API or webhooks and no client workspaces. Instantly Growth shows Unibox replies in preview only, has no webhooks and does not include team invites or the client portal. Budget for Smartlead Pro or Instantly Hypergrowth as the real starting point.
Which has the better lead database?
Instantly has the bigger and more flexible one. Its lead finder page claims 450M+ verified contacts, with keyword search, lookalike search from a client’s domain, and waterfall work email enrichment across 5+ providers. You pay with credits: about 0.5 credits per enriched row and about 1.5 for a work email, per its pricing file. That suits recruiters who build niche lists, such as hiring managers at companies in one city.
Smartlead’s SmartProspect page claims 300M+ profiles, triple verified, with “no per lead fees”. It calls the leads free, but there is a $59 a month “quality upkeep fee” on Base and Pro. On Unlimited Smart (50,000 verified emails a month) and Prime (170,000), it is included. If you send high volume and do not need deep filters, that bundle is good value.
Which has better deliverability tools?
Both cover the basics on every plan: unlimited warmup, inbox rotation, bounce protection and a global blocklist. Neither can promise inbox placement, and both deliverability claims below are the vendors’ own.
Instantly’s warmup page says its pool has over 1,000,000 real accounts, with a slow ramp and read emulation. Its inbox placement tool tests Gmail, Outlook and Yahoo and checks 400+ blacklists and SPF, DKIM and DMARC. You get unlimited one time tests on Growth and unlimited automated tests on Hypergrowth, with no extra fee. Light Speed adds private servers and IP rotation (SISR).
Smartlead’s warmup page describes a private, vetted pool with auto pause on bounce spikes, and the pool tier improves as you move up plans. Placement testing is the paid SmartDelivery add on, and dedicated servers cost $39 each a month. Smartlead suggests at least 2 weeks of warmup for an existing mailbox and 1 to 2 months for a new domain.
Whichever you choose, check your setup first with our free SPF DKIM DMARC checker and run your copy through the cold email spam checker. For more sending tools, see our deliverability category.
Which is better for API, webhooks and AI agents?
Smartlead has the stronger reputation with technical agencies. Its API page offers up to 25 named API keys, webhooks on reply, bounce and unsubscribe, native HubSpot, Salesforce, Pipedrive and Zoho links, and Zapier, Make and n8n. Its MCP server lists 170 actions. The catch: none of this is on Base.
Instantly includes API access on every plan, with webhooks from Hypergrowth. Its developer docs cover API v2, OAuth for Google and Microsoft accounts, sub workspace management, a TypeScript SDK, a CLI and an MCP server. Its homepage shows a ChatGPT connector, with Claude marked “coming soon”.
Who should choose Instantly?
- Recruiters who want to build niche lists and send from one tool.
- Small desks that want unlimited placement tests with no add on fee.
- Agencies whose clients can share one portal view.
- Teams that want a built in CRM with calls and SMS.
Who should choose Smartlead?
- Agencies that need each client fully separate and white labeled.
- High volume senders who want verified leads included in the plan.
- Technical teams building on the API, webhooks and MCP.
- Solo recruiters on a tight budget who only need basic sending (Base).
What are the best alternatives to Instantly and Smartlead?

| Tool | What it does differently | Best for |
|---|---|---|
| Email and LinkedIn steps in one sequence | Teams that want one multichannel tool | |
| Cold email sequencer with unlimited mailboxes | Budget conscious small teams | |
| Sending platform aimed at high volume agencies | Agencies sending millions a month | |
| Cold email with warmup and agency workspaces | Agencies trying a newer option | |
| Simpler sequencer with safety limits built in | Recruiters sending lower volume |

How should you trial both?
Both start free with no card. Instantly’s 14 day trial caps you at 1,000 emails and 250 contacts, so plan a small test. Smartlead does not publish its trial length, but offers 50% off the first paid month.
Use separate mailboxes in each tool so the results do not mix. Warm them for at least 2 weeks before sending. Then run the same list type, the same copy and the same daily limits in both. Score inbox placement, replies per 100 sends and how long it took to set up a client view.
Quick answers
Is Smartlead cheaper than Instantly?
At the entry level, yes: $390 a year for Smartlead Base against $451.20 for Instantly Growth on yearly billing. At mid size they are within $10 a year. For large agencies happy with one shared portal, Instantly Light Speed is about $1,036 a year cheaper than Smartlead Prime with 5 client workspaces.
Do both tools allow unlimited email accounts?
Yes. Both include unlimited sending accounts and unlimited warmup on every plan. Limits are on emails sent and contacts stored, not mailboxes.
Does Instantly include leads?
Not in the outreach plan. SuperSearch leads use Instantly Credits, a separate subscription from $9 a month, unless you buy a bundle such as Starter at $94 a month. Credits expire after 2 months on monthly billing.
Which one has white label for agencies?
Both. Instantly includes a branded client portal on Hypergrowth and Light Speed. Smartlead charges $29 a month per white labeled client workspace from Pro, with 3 included on Prime.
Do the entry plans include API access?
Instantly Growth includes the API but not webhooks. Smartlead Base includes neither; both start on Pro.
Which is better for recruiters?
A recruiter doing business development on one desk will usually get more from Instantly, because list building and sending sit in one place. A recruitment agency running outreach for several brands or clients will usually prefer Smartlead’s separate workspaces.
Is there a long contract?
No. Both offer monthly or yearly billing. Smartlead states there is no lock in and you can cancel any time.
