Overview
Instantly vs Apollo: the short answer
Pick Apollo when finding contacts is the hard part. Pick Instantly when sending at volume is the hard part. Many teams use both. Published terms, October 2026.
| Instantly | Apollo | |
|---|---|---|
| Built for | Sending cold email from many mailboxes | Finding contacts, then sequencing and calling them |
| Pricing basis | Per plan, by contacts and monthly emails | Per seat; all seats on the same plan |
| Entry paid plan | $47/mo (Growth) | $65/seat/mo, or $49 billed annually (Basic) |
| Free option | 14-day trial | Free plan, plus 14-day trial of paid plans |
| Contact data | SuperSearch, on separate credits from $9/mo | Credits included with every seat |
| Mailboxes | Unlimited on every plan | 1 per user on Free and Basic; unlimited Google & Microsoft from Professional |
| Sending limit | Monthly emails per plan (5,000 to 500,000) | 250 a day on Free and Basic; unlimited from Professional |
| Warmup | Unlimited, every plan | Paid plans: 1 mailbox free, then 200 credits a month each |
| Multiple sending mailboxes | Unlimited, rotated within a campaign | From Professional |
| Dialer | Not on its pricing page | From Basic (credits apply) |
| CRM | Add-on, $47 or $97/mo | Deal management built in; Salesforce and HubSpot integrations |
If you already have a list, or buy one elsewhere, Instantly gives you more sending capacity per dollar because it doesn't limit mailboxes on any plan. If your reps need to find people, call them and track deals in one place, Apollo covers more of the job. The two overlap in the middle: Instantly sells a lead database and Apollo can send sequences, but neither is as strong at the other's core job.
What Apollo is
Apollo is a sales platform built around a B2B contact database. You filter by title, company, industry and more, reveal emails and phone numbers with credits, and add contacts to sequences of emails, calls and tasks. Each seat includes data credits, a unified inbox, Chrome, Gmail and Salesforce extensions, and from Basic a dialer and deal management. Every seat on an account must be on the same plan.
What Instantly is
Instantly is a cold email sending platform. You connect as many Google and Microsoft mailboxes as you like, warm them up inside Instantly and run campaigns that rotate sends across them, with replies in a shared inbox called Unibox. Plans are capped by uploaded contacts and monthly emails, not by mailboxes. Lead data (SuperSearch), the CRM and AI agents are separate subscriptions or add-ons.
Pricing
Apollo pricing vs Instantly pricing
Apollo charges per seat and bundles data credits. Instantly charges per plan for sending and sells data separately. From each vendor's pricing page, October 2026.
| Plan | Monthly billing | Annual (per mo) | Credits per seat | Mailboxes | Daily sends |
|---|---|---|---|---|---|
| Free | $0 | $0 | 75 a month | 1 per user, Gmail only | 250 |
| Basic | $65 | $49 | 2,500 a month | 1 per user | 250 |
| Professional | $99 | $79 | 4,000 a month | Unlimited Google & Microsoft + 5 SMTP per user | Unlimited |
| Organization | Annual only | $119 (min 3 seats) | 72,000 a year | Unlimited Google & Microsoft + 15 SMTP per user | Unlimited |
| Plan | Monthly billing | Annual (per mo) | Includes |
|---|---|---|---|
| Outreach: Growth | $47 | $37.60 | 1,000 contacts, 5,000 emails a month |
| Outreach: Hypergrowth | $97 | $77.60 | 25,000 contacts, 125,000 emails a month |
| Outreach: Light Speed | $358 | $286.30 | 100,000 contacts, 500,000 emails a month |
| Instantly Credits: Nano | $9 | — | 150 credits a month for SuperSearch |
| Instantly Credits: Growth | From $47 | — | 1,500 credits a month |
| Instantly Credits: Supersonic | From $97 | — | 5,000 credits a month |
Apollo's credits are pooled across the team, granted at the start of each billing cycle and don't roll over. On paid plans they also pay for warmup, domains and mailboxes bought through Apollo. Instantly Credits expire 2 months after purchase on monthly plans. Instantly's pricing page doesn't list a per-seat charge, but its help center says inviting team members needs Hypergrowth, Light Speed or a CRM plan.
Example: monthly cost for a team of 3 reps
Example, monthly billing at list prices. Apollo Basic includes 1 mailbox per user; Instantly Hypergrowth includes 125,000 emails a month and unlimited mailboxes. Growth credits are Instantly's 1,500-credit Instantly Credits plan. Mailboxes not included.
| Apollo Professional × 3 | $297 |
|---|---|
| Apollo Basic × 3 | $195 |
| Apollo Basic × 1 + Instantly Hypergrowth | $162 |
| Instantly Hypergrowth + Growth credits | $144 |

Deliverability
Apollo cold email: mailbox limits and deliverability
Cold email volume is limited by how many mailboxes you send from, not by the tool's plan cap. This is where the two differ most.
On Apollo Free and Basic, each user connects one mailbox and sends up to 250 emails a day. That 250 is a platform cap, not a safe pace for cold email. Jetmail plans around 30 cold emails per mailbox a day, about 660 a month over 22 sending days. At that pace, a 3-person team on Basic has 3 mailboxes and roughly 1,980 safe cold emails a month.
To send 25,000 cold emails a month you'd want about 38 mailboxes across 13 domains. On Apollo that means Professional or Organization, which allow unlimited Google and Microsoft mailboxes per user. On Instantly, every plan allows unlimited email accounts; Hypergrowth covers the volume.
| Deliverability feature | Instantly | Apollo |
|---|---|---|
| Warmup | Unlimited, every plan | Paid plans: 1 mailbox free, 200 credits/mo per extra mailbox |
| Multiple sending mailboxes | Unlimited, rotated automatically within a campaign | Unlimited Google & Microsoft per user from Professional |
| Bounce and reputation protection | Reputation protection and bounce detection, every plan | Reputation & bounce protection, every plan |
| Buy domains and mailboxes in-app | DFY Google $5/mo, pre-warmed $10/mo, domains $15/yr | Domains 1,500 credits/yr; Google mailboxes 800 credits/mo |

Why split data and sending
- One Apollo seat can supply the data while the sending runs in Instantly, so you don't pay per seat for sending.
- Instantly's unlimited email accounts make it simple to add mailboxes as volume grows.
- If your mailboxes and domains are independent of both tools, you can change either one without losing sending reputation.
Before you upload Apollo leads to Instantly
- Keep only addresses Apollo marks as verified, and test catch-all domains in small batches.
- Remove anyone already in an active Apollo sequence so nobody gets two sequences at once.
- Map the columns you personalize on (first name, company, title) before you upload.
- Check your Instantly plan's uploaded-contacts limit: 1,000 on Growth, 25,000 on Hypergrowth.
- Make sure every sending domain passes SPF, DKIM and DMARC. Check with the SPF checker.

Is Apollo or Instantly better for cold email?
For sending cold email at volume from many mailboxes, Instantly is built for the job: unlimited email accounts and warmup on every plan, priced by emails rather than seats. Apollo is better if you mainly need contact data, a dialer and sequences for a few reps in one tool.
Can Apollo replace Instantly?
For small teams, yes. Apollo has sequences, a unified inbox and warmup. The limit is mailboxes: Free and Basic allow one mailbox per user and 250 sends a day. Unlimited Google and Microsoft mailboxes start on Professional at $99 per seat a month ($79 billed annually).
How many mailboxes can I connect to Apollo?
As of October 2026, Apollo's pricing page lists 1 mailbox per user on Free and Basic, unlimited Google and Microsoft mailboxes plus 5 SMTP mailboxes per user on Professional, and unlimited plus 15 SMTP on Organization. The Free plan connects Gmail accounts only.
How much does Apollo cost?
Per seat, Apollo Basic is $65 a month or $49 billed annually, Professional is $99 or $79, and Organization is $119 a month on annual billing only, with at least 3 seats. There's also a free plan. All seats on an account must be on the same plan.
Does Instantly have a lead database like Apollo?
Yes. Instantly's SuperSearch is a B2B lead database, which Instantly says covers 450M+ contacts. It runs on Instantly Credits, a separate subscription from $9 a month for 150 credits, while Apollo bundles data credits into every seat.
Can I send Apollo leads through Instantly?
Yes. Build and verify the list in Apollo, export it as a CSV and upload it to an Instantly campaign. Keep the leads within Apollo's terms: its plans are for internal business use, and reselling the data isn't permitted.
