Short answer: Choose Smartlead if you are an agency that needs many client workspaces or unlimited stored contacts at high volume: workspaces are a $29 monthly add-on per client and the top plan has no contact cap. Choose Instantly if you want sending and a 450M+ lead database from one vendor, or you are a solo founder starting small. Prices checked October 9, 2026.
Key takeaways
- Entry prices are close: Smartlead Base is $39 a month and Instantly Growth is $47 a month, but neither entry plan includes webhooks.
- The first plan with webhooks costs almost the same on both: Smartlead Pro at $94 and Instantly Hypergrowth at $97 a month (checked October 9, 2026).
- For agencies, Smartlead sells white-label client workspaces at $29 a month each from Pro; Instantly includes a white-label client portal on Hypergrowth and Light Speed, but each separate workspace needs its own subscription.
- Lead data is bundled differently: Smartlead includes verified prospect emails in plan allowances (an add-on on Base and Pro), while Instantly sells lead credits as a separate subscription or bundle.

Smartlead and Instantly are the two cold email tools I get asked about most, usually as “which one is better?” The honest answer is that both send cold email well, both let you connect unlimited inboxes, and both warm them up. Where they differ is what each plan unlocks and how lead data is sold. So instead of a feature-by-feature beauty contest, this comparison maps the gates and prices three real team setups. Every price below was checked on both pricing pages on October 9, 2026.

Smartlead plans and prices (checked October 9, 2026)
| Smartlead plan | Monthly | Annual, per month | Contacts stored | Sends / month | Verified prospect emails / month |
|---|---|---|---|---|---|
| Base | $39 | $32.50 | 2,000 | 6,000 | 2,000 ($59/mo add-on) |
| Pro | $94 | $78.30 | 30,000 | 90,000 | 30,000 ($59/mo add-on) |
| Unlimited Smart | $174 | $144.50 | Unlimited | 150,000 | 50,000 (included) |
| Unlimited Prime | $379 | $314.60 | Unlimited | 500,000 | 170,000 (included) |
Smartlead counts stored contacts and emails sent as separate meters, so 2,000 contacts on Base can each receive three emails within the 6,000-send limit. Pro is the first plan with CRM access, API and webhooks, and the option to add client workspaces. Unlimited Prime adds three SmartServers (dedicated sending servers), three client workspaces, a dedicated manager and a private Slack channel. Add-ons include extra SmartServers at $39 per server per month, inbox placement testing (SmartDelivery) from $49 a month, and mailbox purchasing (SmartSenders) from $4.50 per mailbox per month plus $13 per domain per year for fresh Google or Outlook inboxes.
Instantly plans and prices (checked October 9, 2026)
Instantly splits its pricing into two subscriptions you can buy separately or as a bundle: Outreach (sending) and Credits (lead data and AI).
| Instantly plan | Monthly | Annual, per month | What you get |
|---|---|---|---|
| Outreach Growth | $47 | $37.60 | 5,000 emails, 1,000 uploaded contacts; Unibox preview-only |
| Outreach Hypergrowth | $97 | $77.60 | Up to 125,000 emails, 25,000 contacts; webhooks, full Unibox replies, team invites, white label |
| Outreach Light Speed | $358 | $286.30 | 500,000 emails, 100,000 contacts; SISR dedicated server and IP rotation |
| Credits Growth | $47 | $37.60 | 1,500-2,000 credits for SuperSearch, enrichment and AI agents |
| Credits Supersonic | $97 | $87.30 | 5,000-7,500 credits |
| Bundle Starter / Scale / Agency | $94 / $194 / $555 | $85 / $175 / $500 | Outreach plus credits; Agency adds 500,000 emails, 100,000 contacts and 10,000 credits |
A few details matter in practice. Instantly's pricing page lists Hypergrowth at 125,000 emails in the plan card and 100,000 in its comparison table, so plan on the lower figure until support confirms. Credits expire two months after purchase on monthly plans. Work-email enrichment uses about 1.5 credits per row, so the $47 Credits Growth plan covers roughly 1,000 to 1,300 enriched work emails a month (our estimate from Instantly's published rates). An Outreach add-on at $87 a month adds 25,000 contacts and 125,000 emails on eligible plans. Instantly also sells done-for-you Google accounts at $5 a month, pre-warmed ones at $10, and domains at $15 a year.

The feature-gate map: where each must-have unlocks
This is the table I wish both pricing pages showed. Pick the features you cannot live without, and read across to the cheapest plan that has them.
| Must-have | Cheapest Smartlead plan | Cheapest Instantly plan |
|---|---|---|
| Send from unlimited inboxes with warmup | Base, $39 | Growth, $47 |
| API access | Pro, $94 | Growth, $47 |
| Webhooks (push replies to a CRM or Slack instantly) | Pro, $94 | Hypergrowth, $97 |
| Reply to leads from the shared inbox | Master inbox listed as a core feature; plan gating not stated on the pricing page | Hypergrowth, $97 (Growth is preview-only) |
| Invite team members | Not per seat; check plan limits with Smartlead | Hypergrowth, $97 |
| White-label for clients | Pro, $94 + $29 per client workspace | Hypergrowth, $97 (client portal) |
| Dedicated sending servers / IPs | Pro + $39 per SmartServer; 3 included on Prime | Light Speed, $358 (SISR) |
| No cap on stored contacts | Unlimited Smart, $174 | Not on self-serve plans (top is 100,000; add-ons available) |
Monthly list prices, checked October 9, 2026 on each vendor's pricing page and help center.
Three teams, priced
Here is what the same job costs on each tool, using monthly list prices and the cheapest plan that meets every requirement. These are our calculations from the published prices, not quotes.
1. Solo founder: about 1,000 prospects and 4,000 emails a month
| Requirement | Smartlead | Instantly |
|---|---|---|
| Sending only, reply from the mailbox itself | Base: $39 | Growth: $47 |
| Plus replies pushed to a CRM by webhook | Pro: $94 | Hypergrowth: $97 |
| Plus about 1,000 found and verified emails | Base $39 + $59 add-on = $98 | Starter bundle: $94 |
Verdict: close to a tie. If you only need to send, Smartlead Base is the cheapest way in. If you want lead data and sending from one bill, Instantly's Starter bundle is simple. Before either, make sure your domains are set up correctly: read what SPF, DKIM and DMARC are and test your domain with the free email DNS checker.
2. Agency with five clients that each need their own space
| Setup | Smartlead | Instantly |
|---|---|---|
| One account, five branded client workspaces | Pro $94 + 5 x $29 = $239 (30,000 contacts, 90,000 sends shared) | Not a direct match: one Hypergrowth plan ($97) gives a white-label client portal, but clients see your shared workspace |
| Fully separate workspace per client | Unlimited Smart $174 + 5 x $29 = $319 (no contact cap) | 5 x Hypergrowth = $485 (each workspace needs its own subscription) |
Verdict: Smartlead's per-workspace pricing is built for agencies with many separate clients, and it gets cheaper relative to Instantly as the client count grows. Instantly works well for an agency that runs everything from one workspace and only needs a branded portal for client visibility. If you are weighing an agency against doing it yourself, see our view on choosing a cold email agency in the USA, or our guide to the CRM side of running a lead generation agency.
3. High-volume team: 500,000 sends a month
| Smartlead Unlimited Prime | Instantly Light Speed | |
|---|---|---|
| Monthly / annual per month | $379 / $314.60 | $358 / $286.30 |
| Contacts | Unlimited | 100,000 uploaded |
| Dedicated infrastructure | 3 SmartServers included | SISR server and IP rotation included |
| Lead data included | 170,000 verified prospect emails | None (Credits are separate; the $555 Agency bundle adds 10,000 credits) |
| Cost per 1,000 sends at full use | about $0.76 | about $0.72 |
Verdict: Instantly is a little cheaper on sending alone. Smartlead is better value if you need to store far more than 100,000 contacts or want verified emails included. At this volume the tool is the smaller cost; the inboxes and domains behind 500,000 sends are the bigger one. Size them with the cold email infrastructure calculator or see how we run managed cold email infrastructure.
Cost per 1,000 sends by plan
| Plan | Monthly price | Sends included | Cost per 1,000 sends at full use |
|---|---|---|---|
| Smartlead Base | $39 | 6,000 | $6.50 |
| Instantly Growth | $47 | 5,000 | $9.40 |
| Smartlead Pro | $94 | 90,000 | $1.04 |
| Instantly Hypergrowth | $97 | 100,000-125,000 | $0.78-$0.97 |
| Smartlead Unlimited Smart | $174 | 150,000 | $1.16 |
| Instantly Light Speed | $358 | 500,000 | $0.72 |
| Smartlead Unlimited Prime | $379 | 500,000 | $0.76 |
Two lessons. First, entry plans are expensive per email, so if you will send more than about 10,000 emails a month, compare the middle tiers. Second, the gap between the tools is small at every level; deliverability, list quality and copy will move your results far more than a few cents per thousand.
Warmup, deliverability and sending accounts
Both tools let you connect as many Google, Microsoft or SMTP inboxes as you like and rotate sending across them, and both run automated warmup. Smartlead puts each plan in a warmup pool tier (Foundation, Growth, Premium) and sells dedicated servers and placement testing as add-ons. Instantly includes reputation protection and bounce detection on all plans and reserves its SISR dedicated server and IP rotation for Light Speed. Neither tool can rescue a badly configured domain or a poor list, which is why we start every program with authentication checks and list verification; our older post on how deliverability works explains the basics.
Lead data: bundled allowance or separate credits
This is the biggest structural difference. Smartlead builds verified prospect emails into each plan's allowance (2,000 on Base up to 170,000 on Prime), but Base and Pro users pay a $59 monthly add-on to use them. Instantly keeps lead data in a separate Credits subscription that also powers its AI agents, so heavy AI use and heavy prospecting draw from the same pool. If you already buy data elsewhere (Apollo, ZoomInfo, a list provider), neither data option matters much and you can compare on sending alone.
Who should choose what
- Choose Smartlead if you are an agency with many clients that each need a separate, branded workspace, if you need unlimited stored contacts, or if you want verified emails inside your plan at higher tiers.
- Choose Instantly if you want sending, a large lead database and AI agents from one vendor with one login, if you are a founder starting with a bundle, or if you want the lowest list price at 500,000 sends.
- Either works for a growing in-house team on the middle tier: Smartlead Pro and Instantly Hypergrowth are within $3 of each other and both include webhooks. Run both trials with the same two inboxes and pick the inbox and reporting your reps prefer.
- Neither alone if you lack the time to build infrastructure, write copy and answer replies. That is a service problem, not a software one; our B2B lead generation service and pricing page show what the done-for-you route costs.
Where the replies go next
Whichever tool you pick, a positive reply is only useful if someone answers it the same day. Smartlead and Instantly both have inboxes for that, but teams with several reps often route positive replies into a separate CRM. Our own Tailr CRM turns positive replies from Smartlead or Instantly into assigned leads with follow-up tasks automatically. Once replies are flowing, the follow-up templates for prospects who go quiet and our B2B cold email templates keep the sequence moving. More comparisons and guides are on the cold email topic hub.
Bottom line
Smartlead and Instantly are closer than their marketing suggests. At the tier most teams actually need, with webhooks and full reply handling, they cost $94 and $97 a month. Pick Smartlead for agency workspaces and uncapped contacts; pick Instantly for an all-in-one data and sending bundle. Then spend your energy on the parts that decide results: domains, lists, copy and fast replies.

Frequently asked questions
Is Smartlead cheaper than Instantly?
At entry level, slightly: Smartlead Base is $39 a month versus $47 for Instantly Growth (monthly billing, checked October 9, 2026). The first plans with webhooks are almost level at $94 (Smartlead Pro) and $97 (Instantly Hypergrowth). At 500,000 sends a month, Instantly Light Speed is $358 versus $379 for Smartlead Unlimited Prime, but Smartlead's plan has no contact cap.
Which is better for agencies, Smartlead or Instantly?
Smartlead is usually the simpler fit for agencies running many separate clients: white-label client workspaces are a $29 monthly add-on each from the Pro plan, and Unlimited Prime includes three. Instantly offers a white-label client portal on Hypergrowth and Light Speed, but its help center says each separate workspace needs its own subscription, which adds up when clients need full separation.
Do Smartlead and Instantly both include unlimited email accounts and warmup?
Yes. Both pricing pages list unlimited email accounts on every plan, so you do not pay per mailbox to connect inboxes. Both include automated warmup. Smartlead places plans in different warmup pool tiers, from Foundation on Base to Premium on Unlimited Smart and Prime. You still pay your email provider for each mailbox you create.
Which tool has a bigger lead database?
Instantly says its SuperSearch database holds 450M+ B2B contacts, paid for with Instantly Credits on a separate subscription. Smartlead's help center describes SmartProspect as searching 300M+ verified business profiles, with verified prospect emails counted in each plan's allowance. Database size claims come from the vendors themselves; test a sample in your niche before relying on either.
Which plan do I need for webhooks or API access?
On Smartlead, API and webhooks start on the Pro plan ($94 a month); Base has neither. On Instantly, API access is listed on all Outreach plans, but webhooks start on Hypergrowth ($97 a month). If you want replies pushed into a CRM or Slack the moment they arrive, budget for the webhook tier.
Can I try Smartlead and Instantly for free?
Yes. Both offered free trials with no credit card on October 9, 2026. Instantly's pricing page lists a 14-day trial with 250 uploaded contacts and 1,000 emails. Smartlead's pricing page says every plan has a free trial and showed a first-month discount banner. Use the trial to test deliverability and the reply inbox, not just the editor.
Can I switch from Instantly to Smartlead or the other way?
Yes. Both connect standard Google, Microsoft and SMTP mailboxes, so you can reconnect the same inboxes. Export leads and campaign data as CSV, pause campaigns before moving, and rebuild sequences in the new tool. Do not run the same mailboxes in both tools at once, or you will double your daily sending and warmup volume.
Should I use Smartlead or Instantly as my CRM?
Both now offer CRM-style features (Smartlead's CRM access starts on Pro; Instantly sells CRM plans), and they work for tracking replies inside the tool. Teams with several reps, pipeline stages and reporting needs usually push positive replies into a separate sales CRM and keep the sending tool for sending.
