Smartlead vs Apollo

Reachkit makes a competing cold email tool. I checked every price here in October 2026 against Smartlead’s and Apollo’s own pages.

My verdict: pick by the job you do most. Apollo.io is strongest at finding people, with a large contact database, phone numbers and CRM sync, plus sequences to email them. Smartlead is strongest at sending, with no per-mailbox fees, warmup on every plan and client workspaces, plus its own lead data as an add-on. Finding leads in Apollo and sending through Smartlead works too, with catches I cover below.

Pick Smartlead if:

• You send from dozens of mailboxes and want warmup and rotation on every plan, with no fee per mailbox.
• You run outbound for clients and want white-label client workspaces, which cost $29 a month each on Pro and up.
• You want lead data bundled with volume: Unlimited Smart ($174 a month) includes 50,000 verified prospect emails.

Pick Apollo if:

• Your team prospects, calls and emails from one place, with mobile numbers, a dialer and two-way Salesforce or HubSpot sync.
• You build lists from intent topics, technologies, job postings or funding rounds.
• Each rep sends modest volume from their own mailbox, which Apollo’s free plan or a Basic seat covers.

Checked October 2026. USD, monthly billing, from each vendor’s public pages.

In Apollo the database is the product, while in Smartlead it’s an add-on to a sending tool, and that shapes how each charges for leads.

Apollo, which now calls itself an AI GTM system, reports 240M+ contacts and 30M companies. Its paid plans filter by technologies, job postings, funding and intent topics. A verified email costs 1 credit and a mobile number from 8, and Apollo’s help center rates its verified emails 91% accurate (its AI fact sheet says 98%).

Smartlead’s SmartProspect reports 300M+ verified business profiles, searched with filters like job role and company size and checked through a multi-source waterfall. Base and Pro pay a $59 monthly “quality upkeep” fee for 2,000 or 30,000 verified emails a month; Unlimited Smart and Unlimited Prime include 50,000 or 170,000. Phone-number enrichment arrived in July 2026.

Vendors count records differently, so test a sample from each instead of comparing headline sizes.

Both tools connect your own mailboxes or sell you new ones; Smartlead charges dollars for bought inboxes, Apollo charges credits.

Smartlead links Google or Outlook by sign-in and other providers via SMTP and IMAP, and its guidance keeps a new mailbox to 40 to 50 sends a day, counting warmup. Apollo connects the same ways, but Basic is limited to one mailbox per user, while Professional allows unlimited Google and Microsoft mailboxes plus five SMTP ones.

Smartlead’s SmartSenders buys new domains, configures their SPF, DKIM and DMARC records and hooks Google mailboxes up within 24 to 48 hours, for $4.50 a month each plus $13 per domain a year. Apollo has sold domains and mailboxes for credits since September 2025: 1,500 a year per domain, and 800 a month per Google mailbox or 1,500 per Microsoft one. It sets up the authentication and caps each bought mailbox at 200 emails a day.

Neither promises you can keep bought inboxes if you leave. Per Smartlead’s help center (October 2026), SmartSenders domains expire after one fixed year, with an option to auto-replace them, and can’t be used outside Smartlead. Apollo ties access to bought ones to an active plan and available credits, and advises six weeks of warmup first. Smartlead sells pre-warmed mailboxes ($9 a month) to skip it.

Smartlead gives you more deliverability instruments, while Apollo leans on guardrails that are on by default.

Smartlead includes warmup on every plan, in a pool whose tier rises with the plan, and rotates sends across a campaign’s mailboxes while keeping each lead on one mailbox. Paid add-ons cover dedicated IPs (SmartServers, $39 per server a month) and inbox placement testing (SmartDelivery, from $49). Since August 2026 it reconnects dropped mailboxes in one click, and since September it can auto-replace a mailbox that’s burning out. Per its help center (October 2026), open and click tracking start switched on in each campaign, though its SmartSenders FAQ advises turning both off for Infrainbox mailboxes.

Apollo outsources warmup to Warmbox: each paid seat covers one mailbox, and every extra mailbox costs 200 credits a month. Sequences pause at 6% bounces, catch-all addresses flagged as risky are kept out of sequences by default since September 2026, and paid plans scan sending domains against blocklists every week. Apollo advises switching tracking off without a custom tracking domain. Its placement tests cost no credits; some were marked temporarily unavailable in October 2026.

Apollo’s inbox sits inside a sales workspace, while Smartlead’s is built for many mailboxes and clients.

Smartlead’s Master Inbox gathers replies from every mailbox and client, with filters, bulk actions and reply assignment. Its help center (October 2026) puts the reply check at every 30 to 60 minutes, though a different article promises replies within a minute, and it rechecks just before each follow-up. The help center also lists team members from Pro, though some Smartlead pages say every plan has unlimited seats. White-label client logins run on your own domain and can be limited to Interested replies.

Every Apollo plan includes a unified inbox, with reply filters such as “willing to meet”. Around it sit a dialer, meeting scheduler, call recording, deals and workflows, built for sales teams. Smartlead added calling in February 2026 (SmartDialer, credits from $9 a month), and since July it can pull numbers from SmartProspect.

Both tools run AI inside the product, and both offer an official MCP server: the open protocol that lets assistants such as Claude or ChatGPT work inside other apps.

SmartAssistant, a chat agent on every Smartlead plan since May 2026, sets up campaigns, adds leads and drafts sequences; the Reply Agent drafts replies for you to review, and SmartAgents automate jobs like a daily client report. Apollo’s Assistant is unlimited on paid plans, and since September 2026 Professional and Organization add agents that find prospects and build sequences on a schedule, with your approval for each move.

Smartlead’s API and webhooks start on Pro, and its MCP server authenticates with your API key. Apollo’s MCP signs in with OAuth on every plan, Free included, and works with ChatGPT, Claude, Perplexity, Cursor and Replit; its developer docs put the API on all plans, though its pricing FAQ ties it to custom plans.

Running Apollo for lists and Smartlead for sending is a reasonable split; Smartlead’s own Apollo comparison says teams that need a full sales CRM may use both. Plan for three things:

• Moving leads. Smartlead’s integrations page lists no Apollo connector (October 2026), so leads move by CSV, Zapier, Make or the APIs. Exporting saved Apollo contacts is free; net-new ones with a verified email cost 1 credit each.
• Bounce refunds. Apollo refunds the credit when one of its verified emails bounces within 30 days, but only if you sent it through Apollo. Sending from Smartlead loses that, so I’d recheck big exports with Smartlead’s verification credits (from $32).
• Client work. Apollo’s terms say you may not “access the Platform on behalf of any person or entity other than you”, and its pricing FAQ says sharing its data with customers needs a separate agreement. Its partner program gives qualifying agencies a seat in each client’s own Apollo account instead.

At founder scale the split costs about the same as Smartlead alone. At agency scale, Unlimited Smart already includes 50,000 verified emails a month, so an Apollo seat earns its place through intent filters, enrichment and calling.

Smartlead costs less than Apollo in both setups, mainly because Apollo bills extra inboxes, warmup and domains in credits on top of seats. Assumptions: October 2026 list prices from each vendor’s site, paid monthly, before tax and Smartlead’s first-month discount; Google inboxes and all prospects bought through each tool; Apollo on Professional, because Basic is limited to a single mailbox per user. Apollo’s extra credits are a range, since it doesn’t say how its discount tiers apply.

Founder: one user with 10 inboxes across 5 domains, sending roughly 4,000 emails a month that reach 1,500 new prospects.

Base stores 2,000 contacts at most, so at 1,500 new a month you’d clear finished campaigns monthly or pay for Pro (about $203). Reachkit’s Growth plan fills its 5,000 by month four. With your own inboxes it’s about $98 on Smartlead, $99 on Apollo and $52 on Reachkit, plus mailbox fees. Apollo Basic for data ($65) plus Smartlead Base with bought inboxes comes to about $154.

Agency or team of three: three users, 60 inboxes across 20 domains, roughly 25,000 emails a month reaching 10,000 new prospects.

Reachkit’s first Scale tier holds 25,000 contacts, about 11 weeks’ worth at this pace; its $239 tier brings the total to about $564. Billed yearly, the founder pays about $142 a month on Smartlead, $206 to $209 on Apollo and $98 on Reachkit; the agency pays about $436 on Smartlead and $525 on Reachkit’s $239 tier, while on Apollo it needs more credits than the largest published tier.

Apollo has far more reviews and slightly higher scores; both score much lower on Trustpilot than G2. As of October 2026:

What people like. Smartlead users point to scale without per-mailbox fees and client workspaces, and Trustpilot’s AI summary says reviewers find its tools for managing multiple inboxes reliable. For Apollo, G2’s AI summary credits its verified-contact database, outreach features and Salesforce connection.

What they complain about. For Smartlead: support speed (a Smartlead help article puts typical support replies at 48 to 72 hours; its FAQ aims for 24), billing and cancellation in several 2026 Trustpilot reviews, and a learning curve that even a positive August 2026 Trustpilot review mentions. For Apollo: bounces on emails marked verified, credits consumed unpredictably (Apollo restored them for one Trustpilot reviewer), and an interface some G2 reviewers call overwhelming.

If neither fits, here’s how my own tool differs. Reachkit sets up the sending side for you, and its flat price per workspace includes verified lead data:

• A one-sentence brief becomes a drafted sequence and a sized audience from 500M+ profiles, at 1 credit per verified lead (the $39 Growth plan includes 1,000 a month).
• Google Workspace or Microsoft 365 inboxes set up for you at $5 each a month, on new domains at $15 a year, which start warming automatically.
• Cautious defaults: a ramp from 3 to 20 emails per inbox a day, open tracking off, verified CSV imports and a pause at 5% bounces.
• Unlimited teammates on every plan.

It does less than either tool in places: no white label, placement tests, dialer, phone numbers, intent data or Salesforce sync. Full breakdowns: Reachkit vs Smartlead and Reachkit vs Apollo.

Your own mailboxes, contacts and copy carry over in either direction; inboxes bought from either vendor stay tied to it.

• Mailboxes you own reconnect to the other tool by sign-in or over IMAP and SMTP, and their sender reputation goes with them. Switch off the old tool’s warmup first; Smartlead’s own advice is one sending platform per mailbox.
• Smartlead to Apollo: export each campaign’s leads as a CSV, plus the campaign inbox CSV with reply text. SmartSenders mailboxes can’t leave Smartlead, and Apollo needs Professional before a user can link a second mailbox.
• Apollo to Smartlead: saved contacts export free with flags like Replied, but without the messages themselves, so rebuild sequences by hand. Access to mailboxes bought from Apollo depends on an active plan and credits.
• Contracts: Smartlead’s terms call fees non-refundable, though its refund policy offers new customers a 7-day window. Apollo’s fees are non-refundable, and its annual plans renew unless you give notice 30 days before the term ends.

I’d decide by where the work is. If your team finds people, calls them and tracks deals, Apollo earns its seats, and its sequences are enough at modest volume. If you’re an agency or a founder sending from dozens of mailboxes, Smartlead is the stronger sending tool and cost less in both setups I priced. Pairing them works if you verify exports and check Apollo’s terms for client work. If you’d rather have the inboxes and first campaign set up for you, try Reachkit free for 30 days, no card needed.
