Apollo vs Instantly (2026): What ChatGPT, Claude & Gemini Say

AI models name Apollo more often. Apollo appears in 50 of 50 recorded answers and Instantly in 41 of 50. First place is where they split: Apollo is the first tracked tool named in 32 of 50 answers, Instantly in 1 of 50. All ten models name Apollo in every answer. Instantly matches that in five models and falls to 2 of 5 in Claude.

These are counts of what AI answers name in the 2026-09 edition. They are not a verdict on which product is better.

TL;DR

• Apollo is named more often, and it is named earlier. Instantly is present in most answers but opens almost none of them.
• Instantly holds level with Apollo in five of the ten models. Claude, Claude Opus 5 and ChatGPT are where it drops out.
• The captured comparison pages price Apollo per seat and Instantly per workspace.
• The models and the guides divide the job the same way. Apollo is pitched as data plus multichannel outreach, Instantly as the high-volume sending layer.
• A buyer who needs contact data in the same plan has the stronger case for Apollo. A buyer who only needs to send cold email at volume has the stronger case for Instantly.

How often do AI models recommend Apollo and Instantly?

Apollo leads on every number the panel records. Instantly leads on none.

Apollo is the category leader, so its row is also the reference row. Clay is shown because it sits between the two.

Share is the share of answers that named the product. Named first is the count of answers where it appeared before any other tracked product. Average position is where it sat, on average, in the order of tracked products an answer named.

On presence the gap is modest. Instantly is in most answers. On order the gap is wide. Instantly (82% named, 2% named first) carries the widest named-versus-first gap of all 20 tracked products, at 80 points. Apollo’s gap is 36 points. Put plainly, the models treat Instantly as a tool to list and Apollo as the tool to open with. The full category table is on the AI outbound index.

Which models prefer Apollo, and which prefer Instantly?

No model names Instantly more often than Apollo. What varies is how often each model leaves Instantly out.

Five models name both products in all five answers: GPT-5.6 Sol, GPT-5.6 Luna, Gemini, Gemini 3.5 Flash and Perplexity. In those models the question is never whether Instantly appears. It is where it appears, and on average Apollo sits well ahead of it.

The sharpest disagreement is Claude. It names Apollo in 5 of 5 answers and Instantly in 2 of 5, which is Instantly 40% for that model. Claude Opus 5 and ChatGPT each name Instantly in 3 of 5. Claude Fable 5 and Sonar Reasoning Pro each name it in 4 of 5.

By family the pattern holds. Apollo is named in every answer from all four families. Instantly 100% across Google’s 10 answers, Instantly 90% across Perplexity’s 10, Instantly 86.7% across OpenAI’s 15, and Instantly 60% across Anthropic’s 15. The Anthropic family is where a buyer asking about outbound tools is most likely to see Apollo without Instantly.

Every model’s most-named product in this category is Apollo. The models agree on the leader, and the families agree too.

What do the answers say about each?

The recorded answers mostly split the two by job. Five short extracts from the run:

“If you’re an early-stage founder, start with Apollo.”

GPT-5.6 Sol, answering the founder prompt that asks what to use and why.

“Best default for an early-stage startup: Instantly.”

ChatGPT, answering the prompt about automating cold email at a startup. The answer opens with Instantly.

“if your priority is pure cold-email sending at scale, Instantly is the better fit.”

Perplexity, on the same cold email prompt, after naming Apollo.io as the default for an all-in-one tool.

“For a solo founder doing outbound yourself, Apollo or Instantly are recommended because they offer free tiers, self-serve setup, and low friction.”

Claude, relaying a source it retrieved. The captured Saleshandy guide records no free plan for Instantly, so this relayed claim is contested.

“If you need stronger deliverability or an all‑in‑one stack with built‑in CRM, pair Apollo with Instantly.ai or use Saleshandy alone.”

Sonar Reasoning Pro, on the cold email prompt.

The same division shows up in structure. GPT-5.6 Sol’s comparison answer files Apollo with Clay under prospecting data and enrichment, and Instantly with Smartlead under high-volume email infrastructure.

How do Apollo and Instantly differ?

They are priced on different units and pitched at different buyers. The panel measures names, not prices, so every point in this section comes from a captured comparison page. Vendor records at Apollo and Instantly hold the measured counts.

Pricing model. Saleshandy’s comparison table lists Apollo as priced per seat and Instantly as flat, per workspace. Salesforge describes Apollo’s model as per-user plus credit-based, with cost scaling with team size. It describes Instantly’s as workspace-based, with a flat fee and unlimited seats. Apollo has a free plan, according to lemlist. Saleshandy records a trial and no free plan for Instantly.

What the plan includes. Saleshandy lists Apollo’s contact database as included in the plan. It describes Instantly’s database as a separate subscription from its outreach plans. lemlist says Instantly buyers now purchase Leads, Campaigns and CRM separately. Saleshandy also notes that Apollo credits are annual, shared across the team, and do not roll over.

Who each is for. lemlist’s table places Instantly with individuals and small teams and Apollo with large teams. Salesforge lists Instantly for agencies, cold email freelancers and growth teams scaling volume. It lists Apollo for SDR teams, sales organisations and outbound pipelines that need data plus outreach.

What each is named for. rb2b calls Apollo an all-in-one sales platform covering prospecting through to engagement. lemlist notes that Apollo sends Slack or email alerts when buying intent signals are detected. rb2b describes Instantly as focused on simplifying high-volume email campaigns. lemlist prefers Instantly on warm-up because it has a dedicated warm-up feature.

Where the pages disagree. Saleshandy says Apollo does have warm-up, and that it runs through a third party, Warmbox.ai. Salesforge calls Instantly email-only in its overview. The same Salesforge page later lists email, calling and SMS for Instantly. Saleshandy lists email, calls, SMS and web visitors as Instantly’s channels. Check the current product before relying on any single guide’s feature list.

When should you pick Apollo?

Pick Apollo when you want contact data and outreach in one plan, and when being the tool AI answers open with matters to you.

• Every one of the ten models names it in all five answers, and 32 of 50 answers name it first. A buyer asking any model in this panel will see it, usually at the top.
• The contact database comes inside the plan, as the pricing section above records, so data and sequences sit under one seat.
• Its sequences hold email, LinkedIn and call steps together, according to Saleshandy.
• lemlist places it with sales intelligence and lead generation.

The trade-off is cost per head. The per-seat, credit-based model recorded above grows with team size.

When should you pick Instantly?

Pick Instantly when the job is cold email at volume across many inboxes, and you would rather pay per workspace than per seat.

• It is named in 41 of 50 answers, and five of the ten models name it every time. It is a standard part of the answer set, even though it opens only 1 of 50 answers.
• The flat workspace fee recorded above does not grow with headcount.
• Saleshandy lists unlimited email accounts on every Instantly tier.

The trade-off in the captured pages is data. rb2b notes that paying separately for lead generation and email outreach might not suit smaller teams. In the recorded answers, Instantly is often positioned as the sending layer beside a data tool, not as a replacement for one. ChatGPT’s cold email answer is the exception quoted above, where it comes first.

How this sits against the Apollo vs Instantly guides

The four captured guides compare features and prices. Each is published by a company that sells a product of its own, and each promotes that product inside the comparison. No affiliate disclosure appears in the captured text of any of them.

rb2b. Written by Adam Robinson. It closes by presenting RB2B’s website visitor identification as something neither tool offers.

lemlist. Written by Rémi Kokabi. Its FAQ gives Apollo sales intelligence, large teams and buyer intent data, and gives Instantly email-focused outreach with strong warm-up. It then recommends lemlist as the best overall option. Lemlist is one of the 20 products this panel tracks. It is named in 7 of 50 answers.

Saleshandy. Written by Dhruv Patel. It carries the clearest pricing-model table and corrects its own earlier claim that Apollo dropped email warm-up. It presents Saleshandy as the answer when both fall short. Saleshandy is also tracked here. It is named in 8 of 50 answers and first in 3 of 50.

Salesforge. Written by Daniel Sanchez and presented as tested findings. It argues for Salesforge and Warmforge as a separate deliverability and personalisation layer. salesforge.ai is also one of the hosts the models cite most in this category, with 34 citations across the recorded answers.

The results page also held a Reddit thread that could not be captured, Instantly’s own comparison page, a G2 comparison and a three-way guide from DevCommX. None of those were read for this page.

Those guides compare features. This page counts what AI answers name. It adds the named and named-first counts, the model-by-model split, and the places where a model repeats a claim that a captured guide disputes.

How the sample was built

10 models x 5 fixed prompts = 50 recorded answers. Each model answered each prompt once. The five questions, verbatim:

• What is the best AI outbound sales or prospecting tool for a founder doing outbound? Name specific products.
• Which AI outbound sales or prospecting tool would you recommend to a founder doing outbound in 2026?
• Compare the top AI outbound sales or prospecting tool options right now.
• I’m a founder doing outbound and I need an AI outbound sales or prospecting tool. What should I use and why?
• Best AI outbound sales or prospecting tool to automate cold email at a startup?

The ten models come from four families. OpenAI supplies GPT-5.6 Sol, ChatGPT and GPT-5.6 Luna, for 15 answers. Anthropic supplies Claude Opus 5, Claude and Claude Fable 5, for 15 answers. Google supplies Gemini and Gemini 3.5 Flash, for 10 answers. Perplexity supplies Perplexity and Sonar Reasoning Pro, for 10 answers. The panel tracks 20 products in AI outbound and prospecting, and all 20 were named at least once. The full method is on the method page.

What these counts cannot tell you

The counts measure presence in AI answers. They say nothing about deliverability, data accuracy, support, uptime or fit with a particular stack. Being named is not the same as being recommended, because an answer can name a product only to warn against it. Each model answered each prompt once, in English, through its API, which can differ from what a consumer chat app returns. This is one dated snapshot, the 2026-09 edition. Products are matched by name, so a mention under an unexpected spelling can be missed. One of the five prompts asks specifically about cold email, and prompt wording shapes which tools appear. The feature and pricing points above are the captured guides’ own claims, not tests by MEMETIK.

Frequently asked questions

Who is Apollo’s biggest competitor?

In this panel, it is Clay. Clay is named in 44 of 50 answers and first in 7 of 50, second to Apollo on both counts. Instantly is third on named count, at 41 of 50. Competitor here means named alongside Apollo in AI answers, not market share.

Who are Instantly.ai’s main competitors?

By the counts, Smartlead is its closest match. Smartlead is named in 39 of 50 answers, and its model-by-model pattern tracks Instantly’s closely: both are named in all five answers from GPT-5.6 Sol, GPT-5.6 Luna, Gemini, Gemini 3.5 Flash and Perplexity. GPT-5.6 Sol also groups the two together as high-volume email infrastructure. Apollo and Clay are named more often than either.

Does Apollo AI actually work?

This panel does not test that. It records that all ten models name Apollo in every answer and that 32 of 50 answers name it first. That is visibility, not performance. The captured guides raise their own caveats. The rb2b reviewer reports occasionally hitting outdated email contacts in Apollo’s data.

Is there anything better than Apollo?

The counts cannot rank products on quality. They show that no tracked product is named more often than Apollo or first more often. The closest is Clay. One GPT-5.6 Sol answer, to the prompt asking a founder to name specific products, picks Clay as its top choice.

Can you use Apollo and Instantly together?

Yes. lemlist says some teams use Apollo for lead data and research, then export contacts to Instantly for email sequences. It adds that this raises complexity and cost. Sonar Reasoning Pro’s cold email answer suggests the same pairing when stronger deliverability is the priority.
