Instantly review: cold email infrastructure for founders
Instantly is the tool many founders and agencies use to run cold email properly: lots of sending inboxes, warmed up and rotated from one place. Here is what you get, what it really costs and who should skip it.
Quick answer
Is Instantly worth it?
Yes, if cold email is your main outbound channel. From $47/mo it gives you unlimited sending inboxes and warm-up, A/Z testing and deliverability protection, with a 14-day free trial and no card. Budget extra for lead data (sold as credits) and for your own sending domains. If you'd rather reach people already showing buying intent on LinkedIn, look at Gojiberry.
First-look score
The best-value way to run cold email properly, from one inbox to fifty.
Why this score: The best value once you're sending at volume, with unlimited inboxes and warm-up on every plan. It scores a little lower for founders because leads cost extra (credits from $47 a month), and new inboxes need about two weeks of warm-up before you can send.

What we like
- Unlimited sending accounts and warm-up on every plan, so scaling inboxes costs nothing extra
- Cheap to start: $47/mo, with a 14-day free trial and no card
- A/Z testing, analytics and bounce protection built in
- API, webhooks and integrations on every plan
Limitations
- Growth caps you at 1,000 uploaded contacts and 5,000 emails a month
- Lead data is a separate subscription (credits), so the real cost is often higher
- You still need to buy and set up sending domains and inboxes yourself (or pay for done-for-you ones)
Who should skip Instantly
- You don't have a defined list or ideal customer profile yet; volume won't fix targeting
- You mainly sell to UK sole traders or partnerships: PECR needs their prior consent for marketing email
- You want warm, signal-led conversations more than volume; start with an intent tool like Gojiberry
What Instantly does
Instantly is a cold email platform. You connect as many sending inboxes as you like, warm them up, and run multi-step sequences across all of them from one dashboard.
Every plan includes unlimited email accounts and unlimited warm-up. That’s the main reason founders and agencies choose it: adding inboxes to send more safely doesn’t raise your Instantly bill.
On top of sending, you get A/Z testing, campaign and account analytics, bounce detection, a global block list, and an API with webhooks.
The setup you’ll need
Instantly handles warm-up and rotation, but cold email at any volume still needs some groundwork:
- Separate sending domains. Never send cold email from your main domain.
- SPF, DKIM and DMARC set up on each sending domain.
- Time: warm new inboxes up for a couple of weeks before you start a campaign.
Budget for the domains and inboxes on top of your Instantly plan.
Pricing: what it really costs
| Plan | Monthly | Billed annually | Uploaded contacts | Emails a month |
|---|---|---|---|---|
| Growth | $47 | $37.60 | 1,000 | 5,000 |
| Hypergrowth | $97 | $77.60 | 25,000 | 125,000 |
| Lightspeed | $358 | $286.30 | 100,000 | 500,000 |
For most founders, Growth is enough to start. The first wall you’ll hit is the 1,000 uploaded contacts, and the jump to Hypergrowth is a big step up in both price and headroom.
Leads are extra: Instantly’s lead database runs on credits, from $47 a month for 1,500. You can also bring your own list from another source.
A UK note: who you can cold email
Under the UK’s PECR rules, you can send B2B cold email to limited companies and LLPs if you say who you are and make opting out easy. Sole traders and some partnerships count as individuals, so they need to have agreed to hear from you first. If your market is mostly sole traders, cold email is the wrong channel.
What our 30-day test will measure

Instantly or Gojiberry?
Instantly is for volume: you bring the list and it sends well. Gojiberry finds people already showing buying intent and reaches them mainly through LinkedIn. Read our Gojiberry vs Instantly comparison to see which to start with.
