Cold email outreach platform with unlimited email accounts, automated warmup, deliverability monitoring, and a B2B lead database — built for high-volume sales teams and agencies.
Send cold emails at scale with unlimited accounts, automatic warmup, and deliverability protection — built for sales teams and agencies who need high-volume outreach.
Instantly is a sales engagement and lead intelligence platform built specifically for cold email outreach at scale. It targets B2B sales teams, lead generation agencies, recruiters, and founders who need to send high volumes of personalized outbound email without burning their sender reputation. Unlike traditional sales engagement tools that cap the number of inboxes you can connect, Instantly allows users to attach unlimited email accounts to a single workspace and rotate sends across them, which is the standard pattern for modern cold email operators trying to hit deliverability targets while sending thousands of emails per day.
The core of the product is the campaign builder, where users design multi-step sequences with conditional branching, A/B testing for subject lines and body copy, and spintax for natural variation across recipients. Sends are throttled and randomized across connected mailboxes through a feature Instantly calls inbox rotation, which spreads volume evenly to mimic human sending patterns. Every connected mailbox can be enrolled in the built-in warmup network, where mailboxes automatically exchange replies with thousands of other warmup accounts, mark messages as important, and remove them from spam — gradually establishing sender reputation with the major inbox providers.
Layered on top of campaigns is a deliverability suite that includes domain and DNS health checks (SPF, DKIM, DMARC), bounce detection, spam-word scanning, and a unified inbox where reply management happens. Instantly also bundles a B2B lead database with filtering by job title, industry, company size, technographics, and intent signals, which can push contacts directly into a campaign without an external enrichment tool. A built-in CRM tracks opportunities through pipeline stages with revenue attribution, so teams running outbound through Instantly do not need a separate Salesforce or HubSpot instance for top-of-funnel work.
More recent additions include AI-generated email copy, AI personalization at the line level using publicly available signals about each prospect, and an analytics layer that scores campaign and inbox performance. The platform's pricing model separates sending volume (Growth, Hypergrowth, Light Speed tiers) from lead database credits and from CRM seats, which gives heavy senders a way to scale email volume independently of contact data spend. Instantly is widely used by lead generation agencies running outreach on behalf of multiple clients, where the unlimited-inbox model and per-workspace separation are especially valuable.

Buy Instantly for team-based cold email at scale - saves 60-75% vs per-seat tools like Lemlist ($395/month) or Apollo ($395/month) for 5 users. The Hypergrowth plan ($97/month) provides unlimited accounts and users, making it ideal for agencies and high-volume sales teams. Skip if you need multichannel outreach or integrated CRM functionality.
Connect any number of Gmail, Outlook, or SMTP-based mailboxes to a single workspace. Campaign sends are automatically distributed and rotated across the connected pool, with per-inbox daily limits, ramp-up schedules, and random delays between sends to mimic human behavior. This is the mechanism behind Instantly's reputation for scaling outbound from one mailbox to dozens or hundreds without manual orchestration.
Every connected mailbox can be enrolled in Instantly's warmup pool, where it exchanges natural-looking conversation with thousands of other warmup accounts. Replies, opens, and inbox placement signals are generated automatically, with the goal of rescuing messages from spam and gradually establishing sender reputation. Warmup volume is configurable and runs continuously in the background.
DNS health checks for SPF, DKIM, and DMARC are surfaced inline on each connected domain, with guided fixes. Spam-word and content checks run on campaign copy before launch, and ongoing monitoring flags bounce rate spikes, blacklist hits, and inbox placement drift across major providers.
Built-in contact data with filters for job title, seniority, industry, company size, technographics, location, and intent signals. Leads can be pushed directly into a campaign in one click, eliminating the CSV import dance between a separate data tool and the sending platform. Credits are sold per plan with the option to top up.
Every reply from every connected mailbox lands in one shared inbox, where teammates can triage, assign, label, and respond. Auto-detection of out-of-office, bounces, and unsubscribes routes responses to the right state without manual sorting. Positive replies can be marked as interested and pushed into the CRM.
Opportunities created from positive replies flow into a Kanban-style pipeline with custom stages, deal values, and basic revenue attribution. Activity history pulls in the full email thread, and reporting rolls up campaign performance to dollars rather than just opens and clicks.
An AI assistant drafts campaign copy from a short product description and ICP, and a personalization layer generates per-prospect intro lines using publicly available signals. A campaign optimization model scores send-time, copy length, and sequence structure against historical performance.
