Apollo.io Sales Engagement vs Close Compared

Apollo.io's sales engagement platform features, as its own product page lists them, are six connected products: sequences, a dialer, tasks, Book of Business, AI messaging and a meeting scheduler. Its pricing page decides which of them a team actually gets: the Free plan carries 2 sequences per team, and unlimited sequences start on Basic at $49 a seat a month billed annually. Close sits on the other side of the same run, as the CRM where a conversation gets recorded, and its tier that does outbound work is Growth, not the cheapest card on the page.

That gap between the headline price and the tier carrying the capability is the first thing to check when a team weighs Apollo.io against Close.

Apollo.io Sales Engagement Platform Features

Apollo's sales engagement page lists six connected products: Sequences for multi-channel outreach across email, calls and networking platforms, a Dialer, Tasks, Book of Business, AI Messaging and a Meeting Scheduler, all running on its deliverability suite. The same page marks Book of Business as coming soon. On the pricing page, Free carries 2 sequences per team, Basic unlimited sequences, and Professional adds A/Z testing.

The plan comparison is where the engagement limits live. Free and Basic both allow 1 mailbox per user and 250 email sends a day; Professional lifts sends to unlimited and allows unlimited Google and Microsoft mailboxes plus 5 SMTP mailboxes per user, Organization 15. Calling runs on credits: the page prices the US dialer at 2 credits per minute, an email at 1 credit and a phone number at 8, and sells an Advanced Dialer add-on with parallel, power, international dialing and local presence at $119 per team a month billed annually.

Tier	Sequences	Mailboxes, sends
Free, $0	2 per team	1 mailbox a user, 250 sends a day
Basic, $49	Unlimited	1 mailbox a user, 250 sends a day
Professional, $79	Unlimited, plus A/Z testing	Unlimited Google and Microsoft plus 5 SMTP; unlimited sends
Organization, $119	Unlimited, plus A/Z testing	Unlimited Google and Microsoft plus 15 SMTP; unlimited sends

Organization has a 3-seat minimum and is sold on annual billing only.

The Short Answer

Buy for the gap you can name. If deals are being worked and nobody can describe the pipeline, Close is the purchase. If the pipeline is fine and the top of it is empty, Apollo.io is the purchase. If both are true, the pipeline goes first.

Both vendors publish a rate, so the pair can be costed on paper before anyone books a call. Buying one first, running it for a quarter and adding the second only if the first leaves a gap you can point at is still the cheaper way in.

Where Each Tool Fits in Your Workflow

CRMs track the whole customer lifecycle and deal pipeline, while sales engagement platforms cover the outreach phase. Apollo.io is where the touch is orchestrated and measured; its homepage describes 240M+ contacts and 30M+ accounts behind it. Close is a CRM built around calling, SMS and email, and its pricing page now puts an AI sales agent it calls Chloe, with a monthly pool of AI credits, on every plan.

The seam between them is where most connected stacks break. Decide which system owns contact status before anything is connected, match the two on email address, and read fifty joined records by hand before the whole list goes near the connection.

What Each Side Does in a Cold Outbound Run

Neither of these tools sends cold volume for you. Close is where a conversation gets recorded once it exists, and Apollo.io is where the touch is orchestrated and measured. Cold sending itself happens on separate, warmed sending inventory, which is a different purchase again.

Worth stating the sending doctrine plainly, because it changes what either tool is worth: one message per campaign, and no follow up under it. A sequence step that lands beneath an ignored email is a bump, so the sequencing engine matters less than the list feeding it.

Bounce rate is the reason list quality is the lever. Cold volume goes out over shared sending inventory, so a dirty list costs reputation that every other campaign on that inventory pays for, not just the one that sent it.

Meetings are the other place the two categories separate. A meeting counts when it matches criteria agreed in writing before launch, and neither tool decides that. Close is where the agreed definition gets recorded against the account so the same standard survives a rep change.

Pricing Comparison

Apollo.io Pricing

The page opens on annual billing, labelled "Save 24%". On the Monthly tab Organization still shows $149 but is marked "Annual Only", so it cannot be bought month to month.

Close Pricing

Close's page opens on annual billing and labels it "SAVE UP TO 50%". Solo is capped at one user and "Limited to 10k leads", and the page offers a 30-day money-back guarantee.

What the Entry Price Does Not Buy

Close lists "Power dialer" on Growth and "Predictive dialer" on Scale, and both Solo and Essentials carry the line "Workflows not included". "Send bulk email" appears from Growth up. So the $9 on the front of the page buys a place to keep records, and the tier that does outbound work is Growth at $99 a user billed annually, or $109 monthly.

Apollo splits the same way. Its free card lists "2 Sequences" and its paid cards from Basic upward list "Unlimited Sequences", so the free tier is a place to look at the database rather than a place to run outbound from.

The practical consequence is the same either way. Take the number for the tier that carries the capability being compared, not the number at the top of the page, before either tool goes into a budget.

What the Pair Costs at a Realistic Team Size

The team below is invented, not a client. Five sellers, all needing a seat in both systems, no add-ons, no onboarding fee, and the same billing term on both sides.

Keep the billing term the same on both sides: mixing Close's monthly rate with Apollo's annual one understates the bill. Seat count is the variable that moves this most, and it moves it linearly, so the arithmetic scales cleanly in both directions. The argument worth having is whether the Close half is buying anything the Apollo half does not already do for this team.

Where the Two Overlap

The published lists collide on three classes, so the two sit closer together than a category label suggests. On outbound dialing, Apollo's pricing page lists a US dialer with credits applied, and Close lists a power dialer on Growth. On outbound email, Apollo lists sequences, and Close lists bulk email from Growth up. On workflow automation, both pages list automated workflows.

Read that as a decision rather than a feature win. On a house that sends one message per campaign, two systems able to mail the same list is something to settle once, by picking which one owns the send and turning the other one off for that job. This compares the wording of two vendor pages, so it says what each vendor chose to publish, not what either product can be made to do.

Integration Ecosystem

Apollo's pricing page lists Gmail and Microsoft email on Free and all email providers on paid plans, CRM integrations with Salesforce, HubSpot and Pipedrive, Outreach and Salesloft integrations, SendGrid and Mailgun, and LLM integrations through MCP. Close's integrations page lists HubSpot, Gmail, Microsoft 365, Zoom, Calendly, Zapier, Make, Clay, Gong and Reply among a long directory.

Neither Apollo's pricing and integrations pages nor Close's integrations page names a direct Apollo-to-Close integration. HubSpot appears on both, and both connect Gmail and Microsoft mail, so the shared ground is the mailbox and a CRM neither of them is.

Do You Need Both, and in Which Order?

Both on day one is rarely the right shape, and the order matters more than the answer either way. Buy the side that closes the gap you can name, run it for a quarter, then decide whether the second one is still worth its seat cost.

The failure to avoid is buying the second tool to fix a problem the first one was never going to solve. A pipeline nobody updates does not get fixed by better sequencing, and a list that bounces does not get fixed by a tidier deal board.

When to Choose Apollo.io

Choose Apollo.io first when the pipeline is clean and the top of it is empty, you already keep the record somewhere, and the bottleneck is running sequences and calls. Choose Close first when deals are being worked and nobody can describe the pipeline, or when a team that already sequences needs a system built around calling and SMS.

Rolling the Second Tool In Without Breaking the First

Write down which system owns each field before anything is connected. The common mess is two tools both claiming to own contact status, so a rep marks somebody as replied in one place and the other keeps mailing them.

Pick a matching key and stick to it. Email address is the only key that survives a job change badly but joins reliably; company name does not join at all across two systems that normalise it differently.

Run one segment through the connected pair before the whole list goes near it. Fifty records is enough to read by hand, and reading them by hand is what catches a mapping that looks right in a settings screen and is wrong in the data. Count the records that matched, the ones that duplicated and the ones that silently did neither, and widen only after the fifty read clean.

Using Both Together

Many sales teams use both a sales engagement platform and a CRM platform as part of their complete workflow. Apollo.io handles outreach orchestration while Close covers pipeline and deal tracking.

Because neither vendor's page names a direct integration between the two, plan the join before buying the second seat: a connector, the API on either side, or HubSpot where a team already runs it. The part worth deciding before they are connected is which system owns contact status. Two tools both convinced they own it is how somebody who replied keeps getting mailed.

The Decision Shortcut

If the pipeline is the thing nobody can describe, buy Close. If the top of the pipeline is empty, buy Apollo.io. If both are true, the pipeline goes first, because an outbound push into a system nobody maintains produces conversations that get lost rather than deals that close.

If neither is clearly true, buy neither this quarter and fix the list instead. That is the cheapest of the three options and it is the one most likely to move the number.

How These Figures Were Checked

Vendor figures on this page are attributed to the page they appear on, because vendors contradict themselves across their own surfaces.

• Close. Every figure was matched against Close's pricing page as it renders, in both billing states.
• Apollo.io. Every figure was matched against Apollo.io's pricing and sales engagement pages as they render, in both billing states.

Any arithmetic above is this page's own, done on those inputs and labelled illustrative where it appears.
