Short answer: In the Instantly AI vs Apollo.io choice, pick Instantly if cold email volume is the job and Apollo.io if you want one tool for contact data, sequences and calls. Instantly starts at $47 a month for sending and charges separately for lead credits. Apollo.io has a free plan and charges per user, from $65 a month on Basic.
Both appear on our best AI lead generation agents page. Our Instantly review calls it the pick for cold email. Our Apollo.io review calls it the best all-in-one. This post puts them side by side so you can see which pricing shape fits your outreach.

Who is each one for?
Instantly is for teams that send a lot of cold email. The product centers on sending: unlimited email accounts and warmup on the outreach plans, a lead finder and agents that write and reply. Instantly describes its homepage Copilot as a way to find leads, write copy and generate campaigns. If you run several domains and inboxes, this is the shape you want.
Apollo.io is for sales teams that want data and outreach in one place. It combines a B2B contact database, an AI assistant, email sequences and, on higher plans, a dialer and automated workflows. A founder or a small team of reps can find a contact, email them and call them without leaving the tool.
Neither is a fully hands-off AI SDR. If you want an agent to run outbound for you end to end, look at the AI SDR options on our lead generation page instead.
How does pricing compare?
The pricing models differ, so a single “cheapest” answer misleads. Instantly sells outreach and lead credits as separate things. Apollo.io sells seats with credits attached.
Instantly pricing
All figures come from Instantly’s pricing page. Annual prices are shown per month.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Outreach Growth | $47 | $37.60 | 5,000 emails a month, 1,000 uploaded contacts, unlimited email accounts and warmup |
| Bundle Starter | $94 | $85 | 5,000 emails, 1,000 contacts, 1,500 credits a month, AI Sales Agent |
| Bundle Scale | $194 | $175 | 100,000 emails, 25,000 contacts, 5,000 credits a month, AI Reply Agent |
Credits plans start at $47 a month for 1,500 to 2,000 credits. Bigger tiers and an Enterprise plan with custom pricing sit above these. Instantly shows conflicting prices for some mid tiers on its page, so confirm at checkout before you budget for one.
Instantly offers a free trial and says no credit card is required. The pricing page does not state how long it lasts, so check the sign-up screen.
Apollo.io pricing
Apollo’s own pricing page lists four plans: Free, Basic, Professional and Custom. At the time of our check the page did not show dollar amounts to us, so the prices below come from our Apollo.io page, which we built from Apollo’s site in October 2026. Confirm them on Apollo’s pricing page before you buy.
| Plan | Monthly, per user | Billed yearly, per user | What you get |
|---|---|---|---|
| Free | $0 | $0 | 900 credits per seat per year, 2 sequences, AI Assistant (5 chats) |
| Basic | $65 | $49 | 2,500 credits a month, unlimited sequences |
| Professional | $99 | $79 | 4,000 credits a month, dialer, automated workflows |
Apollo says credits are pooled across your team, granted at the start of each billing cycle and do not roll over. Annual billing means a 12-month commitment. All seats on an account must be on the same plan.
What it costs in practice
Three reps on Apollo.io Basic billed yearly pay $147 a month in total, because the price is per user. One person sending high-volume cold email from many inboxes pays Instantly $47 a month on Outreach Growth or $37.60 billed yearly, and adds credits only if they use its lead finder.
So Apollo.io costs more as your team grows, while Instantly costs more as your sending volume and credit use grow.
Where does each one win?
Where Instantly wins
- Sending infrastructure. Unlimited email accounts and warmup on the outreach plans.
- Price for a solo sender. The lowest paid plan is $47 a month, and it is the lowest paid starting price among the seven agents on our lead generation page.
- Volume. The Scale bundle allows 100,000 emails a month.
- Reply handling. The Scale bundle adds the AI Reply Agent and a unified inbox for replies.
Where Apollo.io wins
- Free start. The free plan has no time limit, so you can test the database before paying.
- One tool for the whole motion. Sequences, an AI assistant and a dialer sit together, so reps do not stitch tools.
- Team features. Admins can set per-user credit caps, and credits are pooled across the team.
- Calling. The dialer starts on the Professional plan. Instantly is built around email.
Where credits can surprise you
Both tools meter lead data with credits, and both reset on a schedule.
On Instantly, outreach and credits are billed separately unless you buy a bundle. Our Instantly page notes that the AI Sales and AI Reply agents use 5 credits per lead or reply, and that unused credits on monthly plans expire two months after purchase.
On Apollo.io, unused credits expire at the end of each billing cycle. Enriching a contact consumes credits, so a team that enriches heavily can hit the cap before the month ends.
If your plan depends on large lead lists, do the math on credits before you compare the headline prices.
How do the AI features differ?
Instantly’s AI sits on the sending side. Its AI Sales Agent is part of the Starter bundle and its AI Reply Agent arrives with Scale. The idea is that the agent writes the outreach and handles replies while you set the rules.
Apollo.io’s AI sits on the research side. Apollo says an AI Assistant is included on every plan, and our page notes agents that can run outbound jobs on a schedule. The free plan limits you to 5 assistant chats, so you will feel the cap quickly if you lean on it.
In both cases the AI draws on credits, so heavier use costs more. Read the output before it goes out under your name.
What neither does
Neither tool fixes a bad offer or a weak list. Both can send email that lands in spam if your domains are poorly set up, and both leave compliance to you, including opt-out rules in the countries you email.
Neither is a full CRM replacement for a large sales team, and neither writes strategy for you. Treat the AI features as drafting help that you review. For a wider view of what agents can do and where they stop, read our AI agents for beginners guide.
Which should you choose?
- You send cold email at high volume from several inboxes: Instantly.
- You are a solo founder who wants to test for free first: Apollo.io’s free plan, then decide.
- You have a team of reps who also call: Apollo.io Professional.
- You want the cheapest paid start: Instantly Outreach Growth at $47 a month.
- You need a lead database and sending in one bill: Instantly’s Starter bundle or Apollo.io Basic, depending on whether you count by seat or by volume.
- You want custom enrichment workflows: neither; look at Clay.
