Amplemarket vs Apollo: Which Should You Choose?

Amplemarket and Apollo both sell a B2B contact database with outreach built on top of it. What separates them is the shape of the commitment. 

The decision comes down to what a small sales team weighs most: entry-tier contents, data reliability, what’s gated higher, and how long you’re locked in. Here’s a look at each platform.

What is Amplemarket?

Amplemarket is an AI-native sales engagement platform that puts contact data, multichannel outreach, buying signals, and deliverability tooling under one subscription. Underneath sits a 200M+ contact database that Amplemarket verifies itself, plus 100+ buying-signal detectors that fire at the contact level and feed a 7-channel outreach engine. On top sits Duo, a suite of agents for research, copywriting, voice, reply handling, and intent monitoring, positioned as a copilot with one-click approval rather than an autonomous SDR. It sells to mid-market B2B outbound teams, with the strongest reported fit at 2 to 10 salespeople running Salesforce or HubSpot.

Pros

• Verified data on every plan: Amplemarket states that all 3 tiers get the same 200M+ AI-verified contacts, 70M+ records refreshed weekly, sub-3% average bounce rates, and 96.5% phone-number accuracy. Nothing about data quality is held back for higher tiers.
• Signals that fire at the contact level: 100+ buying-signal detectors track individual people rather than only accounts, which independent reviewers single out as the platform’s genuinely differentiated capability.
• Consolidation savings with named numbers behind them: Amplemarket reports that switching teams typically retire 3 to 5 separate tools, and cites LILT cutting tooling costs 56% and Agilyx saving $100,000 a year.
• Compliance and CRM sync included at the entry tier: GDPR, CCPA, and SOC 2 apply to every plan. Bi-directional Salesforce and HubSpot sync ships at all 3 tiers rather than sitting behind an upgrade.

Cons

• Annual contracts only, with no monthly path: Multiple independent reviews confirm there’s no month-to-month option, so the minimum commitment is $7,200. There’s a 14-day trial, but you have to book a demo to get access to it.
• The autonomous pieces sit above the entry tier: Duo Copilot and Copywriter are on every plan, but Duo Voice requires Growth, and Duo Inbox, which handles replies automatically, is limited to Elite. The agentic reply handling that makes the product feel hands-off isn’t available at $600 a month.
• International data quality draws mixed reviews: Several independent reviews cite weaker accuracy outside the US, with one reviewer reporting bounce rates reaching 65% on non-US contacts. 

Pricing

Startup is $600 a month on an annual term with 2 user seats included, and it’s the only tier Amplemarket publishes a price for. Growth and Elite are quote-only and raise the included seats to 4 and 10, so a team growing from 3 to 5 people crosses a tier boundary rather than adding a seat. Every plan is annual. Amplemarket publishes phone credit top-ups at $0.50 each, though per-seat pricing beyond the included minimums isn’t listed.

What is Apollo?

Apollo bundles a B2B contact database, sequencing, a dialer, and enrichment into one per-seat subscription, and it’s the default self-serve way into the data category. Apollo publishes a database of 275M+ contacts. The commercial mechanism is a unified credit pool: Every reveal costs a credit, the pool is shared across the team, and unused credits expire at the end of the cycle. Feature access tracks the tiers closely, with the US dialer and call recording starting at Professional and the international dialer, custom reports, and SSO reserved for Organization.

Teams pick it for all-in-one convenience at a price nothing else in the category matches. It serves everyone from solo founders on the free tier up to mid-market sales teams.

Pros

• Free tier that tests the thing you need to test: The free plan opens the contact database with basic filters and the Chrome extension, so you can check coverage for your specific ICP before spending anything.
• Self-serve signup with monthly billing on the lower tiers: Basic and Professional can be bought month to month, which is unusual in a category where most data platforms sell annual contracts only.
• Everything on one bill at a low entry price: Email sequencing, a built-in dialer, intent data, and contact enrichment all ship from $49 per user a month on annual billing. Waterfall enrichment and email warmup are included from Basic.
• Intent topics bundled into the paid tiers: 6 intent topics on Basic rising to 12 on Organization, licensed as part of the plan rather than charged per topic.

Cons

• Credits expire with no rollover: Apollo’s credits FAQ states that credits don’t carry into the following cycle or upon renewal. On annual billing the full year is granted upfront, so unused credits are forfeited at the 12-month mark. Independent analyses flag credit expiration as one of the most common post-signup surprises.
• Data accuracy is the recurring theme, and fixing it costs a second tool: Multiple independent reviews report real-world accuracy around 65–70% and email bounce rates of 20–30% across G2 and Trustpilot. Several conclude that teams need a supplementary verification tool alongside it. That’s a line item the pricing page doesn’t show.
• Organization carries a 3-seat minimum: The page leads with $119 per seat a month, but there’s no single-seat option, so the real entry is $357 a month. The international dialer, custom reports, call transcripts, and SSO all live at that tier, and plans can’t be mixed inside one account.

Pricing

Apollo runs Free, Basic at $49 per user a month, Professional at $79, and Organization at $119 with a 3-seat minimum, all on annual billing. Monthly billing adds roughly 20% and is available on Basic and Professional, which keeps the trial cost low for a small team. Credits are pooled across the team and expire at the end of the cycle, and top-up rates don’t appear on the public pricing page.

Amplemarket or Apollo: Which should you choose?

Both tools solve the same problem. The decision comes down to how much certainty you need before you commit, and how much of the outbound workflow you want in one place. 

One rewards a team that already knows outbound works for them. The other rewards a team still finding out.

Choose Amplemarket if…

Bad contact data is the thing breaking your outbound

If your last 3 campaigns died on bounces and bad numbers, the fix isn’t a bigger list. Amplemarket verifies its own database and publishes what that buys you: 70M+ records refreshed weekly, sub-3% average bounce rates, and 96.5% phone-number accuracy. Those figures apply at every tier rather than only the top plan.

That matters most for a team doing phone-led outbound, where a wrong number costs a dial and a wrong dial costs the hour. It’s worth checking coverage for your specific region first, since independent reviewers report the accuracy advantage is strongest on US contacts.

You’re consolidating 3 or 4 outbound tools into one contract

The $600 entry price reads differently when you’re already paying for a data provider, a sequencer, a deliverability tool, and a LinkedIn automation tool separately. Amplemarket reports that switching teams typically retire 3 to 5 tools. Named customers put numbers on it: LILT cut tooling costs 56% and Agilyx saved $100,000 a year.

Signals, sequences, deliverability, and bi-directional CRM sync all sit on the same subscription, so there’s one renewal and one security review. The 2-seat minimum means you need at least 2 people for the math to work.

Choose Apollo if…

You want to test coverage for your ICP before spending anything

The free tier opens the contact database with basic filters and the Chrome extension. That’s enough to answer the only question that matters at the start: Does this platform have the people you sell to? Run 20 searches against your actual ICP and you’ll know inside an afternoon.

That makes Apollo the lowest-risk first purchase in the data category. There’s also a 14-day trial on Professional when you’re ready to test sequencing and the dialer. Nothing else at this end of the market lets you validate coverage before a sales conversation.

You’re a small team that needs data, sequencing, and a dialer on one bill

At $49 per user a month, you get contact data, email sequencing, waterfall enrichment, email warmup, and 6 intent topics. Professional at $79 adds the US dialer and lifts the sending caps. For a founder-led team of 3, that’s $147 a month on annual billing, or $177 month to month if you’d rather keep the option to cancel.

Apollo also runs a startup discount program. Budget for a verification tool alongside it, since independent reviews put real-world data accuracy around 65 to 70%.

Why AiSDR might be a smarter third option

Both tools hand your team a database and a place to send from. Someone still has to decide who’s worth chasing, write the campaigns, and keep the sequences honest week after week. 

AiSDR is built around that gap. Ami AI runs the strategy, finds the people, and executes the outreach, and it measures success in meetings that show up. 

Ami AI Strategist

The gap both tools leave is strategy. Amplemarket’s Duo is a copilot waiting for your approval, and Apollo hands you filters and a sequence builder. You’re still the one deciding which audiences are worth the effort. Ami closes that.

It reviews your offer, your CRM data, and your past campaigns, and then suggests specific audiences and niches for Live AI search to investigate, based on your goals. It takes about 20 minutes for Ami to analyze your site and build a campaign with messaging angles, sequences, and targeting parameters. You review and launch in 2 clicks.

Ami is trained on 20,000+ campaigns AiSDR has run, so the plays come from what worked rather than from a blank canvas. 80% of AiSDR customers use AI Strategist rather than building campaigns by hand, and campaign execution runs 6x faster than manual.

Live AI search

The second gap is what happens to a database between the day it was collected and the day you email it. Independent reviews report Apollo’s real-world accuracy at 65 to 70% with bounce rates of 20 to 30%, and Amplemarket’s own advantage narrows outside the US. AiSDR takes a different route and builds lists on demand.

Live AI search finds any audience from a plain-text query, including ultra-niche ICPs that filter menus can’t express. The contact data it returns is valid as of today rather than pulled from storage. Ami decides what to look for and Live AI search goes and finds it.

The list gets built against your current campaign rather than drawn from a fixed pool. For a team whose ICP is hard to describe in checkboxes, that’s the difference between a workable list and a compromise.

Intent & CRM data

Timing is the other half of the problem, and both named tools do real work here. AiSDR puts website visitors, LinkedIn profile visitors, LinkedIn social engagement, and LinkedIn keywords together as signals in one place. Your team can see why an account is worth a message right now.

Through its HubSpot and Salesforce integrations, AiSDR scores and enriches your account data for inbound and outbound leads. It then reaches out only to the accounts that qualify. Native HubSpot sync ships on Solo. LinkedIn signals start on Explore, and website visitor tracking and Salesforce sync start on Scale.

Prospects are found through public, verifiable signals that they have the problem you solve, including posts about the issue and trigger events that create urgency. That’s a large part of why AiSDR sees a 9.22% response rate and a 5.63% positive response rate, with 1 to 3 meetings per 100 targeted leads.

Campaign Builder with multichannel conditional sequencing

Channel breadth is where tier gates bite on both tools. Duo Voice needs Growth and Duo Inbox is Elite-only, and Apollo’s US dialer starts at Professional with international calling held back to Organization.

AiSDR’s Campaign Builder runs email, LinkedIn messages, connection requests, InMails, and calls in one flow. You can drop in AI-generated video, voice notes, text, and memes as mediums inside the same sequence. AI video and AI voice notes start on Scale. The interface is drag-and-drop with conditional logic when a campaign needs it.

Behind it, AiSDR handles the infrastructure agencies charge thousands for: lookalike mailboxes, continuous warmup, bi-weekly deliverability tests, and inbox health monitoring. The AI handles replies, objections, and follow-ups until the goal is met. That replaces 8+ standalone tools, and most teams launch their first campaign in about 30 minutes.
