Apollo.io vs ContactOut: Cross-Category Comparison

ContactOut vs Apollo comes down to where the prospecting starts. ContactOut is a finder that works from a person: open a LinkedIn profile or a search result and it returns emails and phone numbers, metered by exports a month. Apollo works from a filter: a 240M-contact database, sequences to send from and a credit pool per seat. For a filtered list worked at volume, Apollo is the better fit; for named people who must each be reached, ContactOut is.

ContactOut vs Apollo: Which Is Better For Sales Prospecting?

For sales prospecting at volume, Apollo, because one seat builds the list, finds the contact and sends the sequence, on a published ladder from $0. ContactOut is better when the list is a set of named people and the hard part is getting a personal email or a mobile for each one. Its paid plans leave email lookups unlimited and cap exports instead, at 300 or 600 a month.

What Each Tool Is Built Around

ContactOut describes itself on its homepage as a finder of emails and phone numbers, with 800M people profiles, 150M personal emails, 200M work emails and 100M direct dials in its database, and a claim of email and phone numbers "for 75% of people online". Those are the vendor's own figures. The product surfaces it lists are a Chrome extension, a search portal, email campaigns, an API and data enrichment, and its own menu splits the use cases into sales and recruiting.

Apollo describes its data as 240M contacts and 30M companies, and its pricing page builds the rest of the workflow around that database: sequences, a deliverability suite with email warmup, waterfall enrichment, a US dialer on which credits apply, and domain and mailbox purchasing from the Basic plan up.

The practical difference is the starting point. A recruiter with a shortlist of twenty named people and a rep with a segment of two thousand companies are both prospecting, and they want opposite tools.

Pricing, Read Plan By Plan

Both vendors publish a real ladder, which makes this one of the few pairs that can be priced without a sales call.

Plan	Price	What the plan meters
ContactOut Free	$0	5 emails, 5 phones and 5 exports a day
ContactOut Email	$49 a month	Unlimited emails, 300 exports a month (list price $99)
ContactOut Email + Phone	$99 a month	Unlimited emails and phones, 600 exports a month (list price $199)
ContactOut Team / API	Contact us	Bulk license, 700 million+ profiles
Apollo Free	$0	900 credits per seat per year, granted monthly
Apollo Basic	$49 a seat	30,000 credits per seat per year, granted upfront
Apollo Professional	$79 a seat	48,000 credits per seat per year, granted upfront
Apollo Organization	$119 a seat	72,000 credits per seat per year, minimum 3 seats

ContactOut's paid plans each carry a "1 user per company limit", so the ladder above is a single-seat ladder; a team goes to the Team / API tier, which is priced by conversation. Its site navigation also advertises "unlimited sales users for $299" under its sales use case, which the pricing page itself does not list as a plan, so treat that as a question for the vendor rather than a price to budget.

How Each Meter Works

The two meters punish different habits, and reading them correctly is most of the buying decision.

ContactOut meters exports. On both paid plans, looking up emails costs nothing; what counts is how many contacts leave the tool each month, 300 on Email and 600 on Email + Phone. That suits a workflow of reading profiles one at a time and exporting only the people worth keeping, and it penalises bulk list building.

Apollo meters credits, and its own pricing FAQ prices the actions: accessing a contact's email uses 1 credit, a phone number uses 8, and data enrichment up to 9 per record. Each paid seat receives its year of credits upfront, 30,000 on Basic, so one Basic seat reaches 30,000 emails or 3,750 phone numbers a year. That suits list building at volume, and a year's allowance granted on day one means a team can front-load a campaign without waiting for a monthly refill.

Put the two meters on the same unit and a pattern appears. At list price, with the whole allowance used, an email from Apollo costs about 2 cents, while a phone number from Apollo and an exported contact from either ContactOut plan all land near 16 cents. Emails are where Apollo is cheapest; phones are where the two converge.

Which Is Better For Finding Personal Emails And Mobiles?

On the vendors' own descriptions, ContactOut is the one built for it. Its homepage leads with personal emails and direct dials as separate counts, and its Email + Phone plan makes phones unlimited to look up, capping only exports. Apollo charges 8 credits for a phone number against 1 for an email, so a team that mainly needs mobiles spends an Apollo seat's allowance eight times faster than one that needs emails.

A claim on a homepage is not a match rate on your list, though. The only coverage test that decides this is a sample of your own target accounts run through both, which is covered below.

What One Year Of Both Actually Costs

The numbers below are invented for the example; the prices are the ones each vendor publishes.

Two Apollo Basic seats are $49 per seat per month billed annually, so $98 a month and $1,176 for the year, with 30,000 credits per seat granted upfront. One ContactOut Email + Phone plan at $99 a month is $1,188 for the year and carries 600 exports a month, 7,200 for the year.

That second line more than doubles the annual cost of the stack, from $1,176 to $2,364, and the case for it cannot be volume, because the exports it buys are small next to Apollo's allowance. It has to be the specific people Apollo returns empty. If Apollo comes back with no address on an illustrative 15 percent of a 2,000-person list, that is 300 people, well inside a month of Email + Phone exports; at an illustrative 3 percent it is 60 people, and $1,188 a year is a lot to pay for sixty addresses.

Where The Two Overlap, And Where They Do Not

Both find work emails and both find phone numbers, so the databases overlap plainly. ContactOut also lists email campaigns and a list builder on its Email plan, and Apollo lists prospecting, Gmail and Salesforce extensions for working from a profile. The overlap is real on both sides.

The separation is the centre of gravity. Apollo's plan cards carry the sending side: unlimited sequences from Basic, a deliverability suite with email warmup, and domain and mailbox purchasing. ContactOut's centre stays on the person in front of you. That is why the two rarely compete on a whole workflow; they compete on individual rows, and the miss rate on a real list decides it.

On integrations, the pages read today say less than most comparisons claim. Apollo's plan cards list CRM integrations and Salesforce and Gmail extensions. ContactOut's pricing page names "Salesforce + ATS integrations" on its Team / API tier; its integrations page sits behind a login, so no fuller list is repeated here.

When To Choose Apollo, ContactOut, Or Both

Apollo first, for most sales teams, because one seat covers building, enriching and sending, and a team that cannot fill a wave does not have a coverage problem yet. ContactOut earns its line when a named list keeps coming back short, particularly on personal emails and mobiles for people whose company records are thin.

The order flips for recruiting-style work. If the job is to reach a specific named set of people rather than a filtered segment, the profile-first workflow is the primary tool and the sending platform is secondary, and a ContactOut plan plus a modest sending setup is a sensible stack.

What to avoid is buying both to cover the same rows. Two subscriptions asked the same question about the same people is the most common form of overlapping spend on this shelf.

What Each Side Does In A Cold Outbound Run

A cold outbound run has a fixed shape: build the list, resolve and verify a mailbox for every person on it, then send. Apollo covers more of that run than its category label suggests, because the seat that sends the sequence also searches, reveals and enriches. ContactOut covers the resolving step, and on its paid plans it also offers campaigns of its own.

RevenueFlow runs one message per campaign, so there are no bump steps and no thread replies scheduled behind the first send. A prospect who does not answer is re-approached later in a new campaign with a different angle, never with a second message stacked under the one they ignored. Reading the reply and booking the meeting sit outside both products; a meeting counts when it matches criteria agreed in writing before launch, and that is the number worth measuring either purchase against.

Using Both Together

Run ContactOut against the rows Apollo already failed on, not against a fresh list. A finder tested on easy rows always looks good, and the only rows that justify a second subscription are the hard ones. Verify every address outside both tools before it is sent to, because a bounce costs the sending domain rather than the data provider.

Whichever order the two arrive in, keep the sending inventory out of the test. Sender domains, mailbox warmup and daily caps are their own project, and a stack change made in the same week as a sending change leaves nothing to attribute a bounce rate to. Change one layer, let a full wave run, then change the next. And export what the incumbent already found before any subscription lapses: contact records bought once are cheap to keep and expensive to buy twice.

Decision Framework

1. Name the gap before naming a tool. Write down which stage is costing meetings: a list that runs out, addresses that bounce, or people Apollo has no address for.
2. Read the meter, not the headline. ContactOut caps exports and leaves lookups unlimited; Apollo grants a year of credits per seat upfront.
3. Price the whole year. Apollo's Organization tier carries a three-seat minimum, and ContactOut's paid plans are one user per company.
4. Trial on the accounts being sold to. Coverage is a property of a segment, not of a database, so a sample of the target list is the only test worth running.
5. Measure at the pipeline, not per tool. Both products feed one funnel, so the honest measure is meetings booked against criteria fixed in advance.

The Short Version

Filtered segments, volume, one seat doing everything: Apollo. A named list of people who have to be reached individually: ContactOut, and the $49 Email plan first. Both, when a measured miss rate on the real list is high enough that 600 exports a month get used.
