Instantly Interactive Demo
Explore a demo of Instantly, a cold email platform that lets you connect unlimited sending accounts, warm them up automatically, and manage all replies in a unified inbox.
What is Instantly?
Instantly is a cold email platform founded in 2021, built around the premise that cold email scale requires sending from many accounts simultaneously rather than burning a single domain. The platform lets you connect an unlimited number of sending accounts on its paid plans, which means teams can spread campaign volume across dozens of inboxes rather than sending thousands of emails from one address. This approach became common practice as email deliverability tightened and domain reputation became harder to maintain at volume.
Every connected account goes through Instantly's built-in warmup process, which simulates natural email activity to build sender reputation before live campaigns start. The warmup network exchanges real emails between accounts in the system, generating positive engagement signals that tell inbox providers the account is a legitimate sender.
Instantly's Unibox consolidates replies from all connected accounts into a single view, so a team managing outreach across twenty sending addresses doesn't need to check each one separately. The platform also has a built-in B2B lead database for prospecting. Growth plan starts at $37/month, Hypergrowth at $97/month. HubSpot and Pipedrive integrations are available for CRM sync.
How to get started with Instantly
- 1
Connect your sending accounts
Sign up at instantly.ai and add your sending accounts by connecting them via Google or Outlook OAuth, or through SMTP. Instantly supports G Suite, Outlook, and most custom domain setups. Add as many accounts as your sending infrastructure includes.
- 2
Start the warmup process
Enable warmup for each connected account. Instantly's warmup network begins exchanging and replying to emails automatically. New accounts typically need two to four weeks of warmup before they're ready for cold campaigns. You can monitor warmup health scores for each account in the dashboard.
- 3
Build or import your prospect list
Search Instantly's lead database or import a CSV with your own prospect data. Map columns to campaign variables like first name, company, and any custom fields you want to use in personalization. Review the list for duplicates or invalid emails before launching.
- 4
Create your campaign and sequence
Write your email sequence with as many steps and follow-ups as you need. Use variables to personalize each email. Set the sending schedule, daily send limits per account, and which accounts will run this campaign. Instantly distributes sends across selected accounts automatically.

Monitor replies in Unibox
Once the campaign is live, replies from all accounts appear in Unibox. Filter by campaign, reply sentiment, or account to prioritize follow-up. Move interested prospects to a pipeline stage or push them to your CRM integration for the sales team to pick up.
Who is Instantly most useful for?
Outbound sales teams and growth hackers running high-volume cold email campaigns who have moved past the point where a single domain can handle their sending needs. Instantly's unlimited account model is built specifically for this use case: connecting ten, twenty, or fifty inboxes and distributing campaign sends across all of them to protect deliverability.
Agencies running cold email campaigns for multiple clients. Each client gets their own set of sending accounts and campaigns within the same Instantly workspace. Unibox lets the agency see all replies in one place and respond without juggling separate email accounts manually. If you want to walk a new client through how their campaign is set up before it goes live, Supademo lets you build an interactive overview of the Instantly configuration that they can review on their own.
Founders and small sales teams doing their own outbound prospecting without a dedicated SDR. Instantly's lead database means you can go from finding prospects to sending emails within the platform, without a separate enrichment tool. The warmup automation handles deliverability maintenance in the background, so there's no manual setup required beyond connecting the accounts.
Instantly competes with cold email tools and outreach platforms that vary in their approach to deliverability, multichannel support, and prospecting data.
Goes beyond email with LinkedIn and phone steps in the same sequence. Less focused on the unlimited-account infrastructure model. Better suited for teams that want coordinated outreach across channels rather than pure cold email scale.

Direct competitor to Instantly with a similar unlimited-account model and built-in warmup. Slightly different pricing structure and interface. Many high-volume senders test both before committing to one.
One of the earlier cold email tools, with a simpler interface and lower sending volume than Instantly. Includes phone dialer integration and LinkedIn steps on higher plans. Better suited to smaller outbound programs that don't need the scale of unlimited accounts.
FAQs on Instantly
Commonly asked questions about Instantly. Have more? Reach out and our team will be happy to help.
How many email accounts can I connect to Instantly?
Instantly's paid plans support unlimited connected sending accounts. The Growth plan at $37/month and Hypergrowth plan at $97/month both include this. The difference between plans is primarily email volume limits, advanced analytics, and feature access.
How does Instantly's email warmup work?
Instantly's warmup network sends emails between connected accounts in the system and automatically replies to them with positive engagement. This tells inbox providers like Gmail and Outlook that the account is active and generating legitimate engagement before you start sending real campaign emails from it.
What is Unibox in Instantly?
Instantly's Unibox is a unified inbox that aggregates replies from all your connected sending accounts in one place. Instead of checking each email account separately, you see all campaign replies in a single interface, filter by campaign or account, and respond directly without leaving the platform.
Does Instantly have a built-in lead database?
Instantly includes a B2B lead database that lets you search for prospects by job title, company size, industry, and other criteria directly within the platform. The database can be used to build prospect lists that feed directly into campaigns, though many teams supplement it with dedicated enrichment tools like Clay for more precise targeting.
How does Instantly compare to Lemlist?
Lemlist supports multichannel sequences including LinkedIn and phone steps alongside email, while Instantly focuses primarily on email. Instantly's unlimited account model and warmup infrastructure is more developed for pure email volume. Lemlist is the better fit if you need coordinated touchpoints across channels.
Can Instantly sync replies to my CRM?
Instantly integrates with HubSpot and Pipedrive for CRM sync. You can configure it to create or update contacts when someone replies and log email activity to the corresponding deal or contact record, keeping your CRM current without manual data entry.
