Pricing takeaway

Apollo's per-user pricing adds up fast for teams. A team of 3 on Apollo Basic costs $147/mo. On Professional, that becomes $237/mo. Organization requires a minimum of 3 users at $357/mo. A team of 5 on Professional costs $395/mo. SendKit Essential at $99/mo covers all 5 users with dedicated IPs, 75K emails, and no per-user fees. SendKit Plus at $249/mo gives that team 250K emails and 100K leads. Apollo's free tier is a genuine advantage for individuals testing the platform, and the 275M+ database is unmatched. But for team-based outbound at scale, SendKit's flat pricing model is significantly more predictable.

Infrastructure and Deliverability

Apollo.io is primarily a sales intelligence and CRM platform that added outbound sequencing. The outreach features are capable, but the infrastructure is designed for a broad sales platform rather than a dedicated cold email tool. SendKit assigns dedicated IPs to every account on every plan from $99/mo.

Your sending reputation is fully isolated. Apollo runs on shared infrastructure across all tiers, from Free through Organization. There is no dedicated IP option advertised on any Apollo plan.

Apollo does include a deliverability suite on Basic ($49/user/mo) and above, which covers warmup and email health features. This is a solid addition. But it operates on top of shared infrastructure, which means your deliverability still depends partly on other Apollo users on your IP cluster.

SendKit bundles inbox placement testing, blacklist monitoring, auto mailbox protection, and email validation into every plan. Based on our review of Apollo's feature pages, they offer warmup and deliverability monitoring but we could not find equivalent inbox placement testing or blacklist monitoring as dedicated features. Auto mailbox protection that automatically pauses sending when bounce rates spike is another SendKit feature without an Apollo equivalent.

Apollo's strength is not infrastructure. It is the 275M+ contact database, waterfall enrichment, advanced filters, and the sales intelligence layer. If you already have strong deliverability practices and your primary need is prospect data, Apollo delivers enormous value.

If you need the infrastructure itself to protect your sender reputation, SendKit is purpose-built for that.

Lead Database and Sales Intelligence

This is where Apollo genuinely excels, and it deserves credit. Apollo's 275M+ contact database with advanced filters, waterfall enrichment, and intent signals is one of the most comprehensive prospecting tools available. The ability to search by job title, company size, industry, technology stack, and dozens of other filters makes it a powerful platform for building targeted prospect lists.

The credit system determines how much data you can access. The Free plan gives you 900 credits per year. Basic provides 30,000 credits per year.

Professional provides 48,000. Organization provides 72,000. Each email lookup or enrichment costs credits, so teams doing heavy prospecting can burn through their allocation quickly.

Additional credits cost extra. Apollo also offers website visitor identification as an add-on, which shows you which companies visit your site. This intent data layer adds context to outbound targeting that most cold email tools cannot provide.

SendKit has a built-in lead finder with a 700M+ contact database. SendKit allocates 500 finder credits on Essential, 1,000 on Plus, and 2,000 on Pro. Apollo's advantage is not just database size but the sales intelligence layer: intent signals, waterfall enrichment, and company alerts that SendKit does not offer.

For teams that depend on intent-driven prospecting, Apollo is the stronger choice. For teams that need solid prospecting with dedicated sending infrastructure, SendKit covers both.

Pricing Breakdown

Apollo's per-user pricing creates a cost curve that scales with team size. We calculated the numbers for common team sizes to make this concrete. A solo user on Apollo Basic pays $49/mo.

That is cheaper than SendKit Essential at $99/mo. For individuals, Apollo's pricing wins, especially with the free tier available for initial testing. But the math shifts as your team grows.

A team of 3 on Apollo Basic: $147/mo. On Professional: $237/mo. On Organization: $357/mo (minimum 3 users required).

A team of 5 on Professional: $395/mo. A team of 5 on Organization: $595/mo. A team of 10 on Professional: $790/mo.

SendKit Essential at $99/mo covers the entire team regardless of size. SendKit Plus at $249/mo gives that same team 250,000 emails and 100,000 leads. No per-user charges.

No minimum user requirements. For a team of 5, SendKit Plus at $249/mo is 37% cheaper than Apollo Professional at $395/mo, and SendKit includes dedicated IPs while Apollo runs shared infrastructure. For a team of 10, the gap widens further: $249/mo vs $790/mo.

The flip side: Apollo's per-user pricing includes access to their 275M+ database with credits at each tier. If your team relies heavily on Apollo's prospecting data, the per-user cost includes access to sales intelligence features (intent signals, waterfall enrichment) that SendKit does not offer. The question is whether that data access justifies the per-user premium.

Features and Workflow

Apollo is built as a full sales platform. Beyond sequences and email, it includes a CRM, automated workflows, call recordings (Professional and above), A/Z testing, customizable reports, and SSO on the Organization tier. The platform covers the entire sales workflow from prospecting to closing.

SendKit is built as a cold email and outbound platform with deliverability at the center. The feature set is focused: sequences with conditional logic, A/B testing, a built-in dialer, CRM, unified inbox, lead finder, AI reply tagging, and comprehensive deliverability tooling. What SendKit does not have is the sales intelligence layer that Apollo offers.

Apollo's A/Z testing on Professional plans is worth highlighting. While most platforms offer A/B testing with 2 variants, A/Z testing lets you test many more variants simultaneously. This is useful for teams running aggressive optimization across subject lines, openers, and CTAs.

Apollo also includes a US dialer on Professional ($79/user/mo) with an international dialer and parallel dialer available as add-ons. SendKit includes a native dialer on every plan from $99/mo with no add-on charges. For calling capabilities, SendKit is more accessible since the dialer is included at every tier.

One area where SendKit has a technical edge: webhooks with 6 event types and HMAC signature verification. This matters for teams running custom integrations or syncing campaign events to external systems in real time. Apollo offers API access on paid plans, but the webhook implementation is less detailed from what we found in their documentation.

Who Should Choose What

We recommend Apollo if you need a sales intelligence platform that combines a 275M+ lead database, CRM, and outbound sequencing in one tool. Apollo is the right choice for sales teams that rely on prospect data, intent signals, and waterfall enrichment to build their pipeline. The free tier is also genuinely useful for individuals testing outbound for the first time.

We recommend SendKit if email deliverability is your top priority and you want flat, predictable pricing that does not scale with team size. Dedicated IPs on every plan, isolated infrastructure, and bundled deliverability tools make SendKit the better choice for teams where inbox placement directly affects revenue. For teams of 3 or more, SendKit's pricing model saves significant money compared to Apollo's per-user structure.

Agencies should look at SendKit. White-label is available from the Pro plan at $499/mo. The Agency plan at $899/mo adds custom reports, 2.5 million emails, and a dedicated account manager.

Apollo does not offer white-label capabilities. Some teams use both platforms together. Apollo for prospecting and data enrichment, SendKit for sending the actual campaigns with dedicated IP protection.

This gives you the best database with the best infrastructure, though it means managing two subscriptions.
