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 cold email outreach platform designed for high-volume senders who need to scale campaigns across dozens or hundreds of email accounts while maintaining inbox deliverability. The platform's core differentiator is unlimited email accounts on every plan — you can connect as many Gmail, Outlook, and custom SMTP accounts as you want without per-seat charges, enabling massive sending scale through account rotation. Instantly's automated warmup system gradually increases sending volume on new accounts by generating realistic email conversations between your accounts and Instantly's warmup network, building sender reputation before campaigns launch. The deliverability monitoring suite tracks bounce rates, spam complaints, and sender reputation per account in real-time, automatically pausing problematic accounts before they damage domain health. Campaign sequences support multi-step follow-ups with conditional logic, A/B testing (on Hypergrowth+ plans), and personalization using custom variables from imported CSV data. The Unibox aggregates responses from all connected accounts into a single inbox with sentiment analysis and auto-categorization. Beyond outreach, Instantly offers a B2B lead database with verified contacts and a lightweight CRM for managing deals — each sold as separate product lines with independent pricing. The Growth plan starts at $47/month with 1,000 uploaded contacts and 5,000 emails monthly. The Hypergrowth plan ($97/month) expands to 25,000 contacts and 100,000 emails with premium support and A/B testing. Light Speed ($358/month) adds 500,000+ emails, 100,000+ contacts, and the SISR system for dedicated IP pools and automatic IP rotation. Annual billing reduces prices by roughly 20%. The real cost is often higher than the base price since most users also need the leads database and additional email accounts/domains.

Instantly is the go-to platform for high-volume cold email outreach, offering unlimited email accounts, automated warmup, and deliverability monitoring at competitive prices starting at $47/month. It excels for agencies and sales teams sending thousands of emails daily across many accounts. The main limitations are email-only focus (no multi-channel), A/B testing locked behind the $97 tier, and real costs that are higher than advertised when factoring in necessary add-ons. For pure email outreach at scale, it's hard to beat on value.
Connect unlimited Gmail, Outlook, and custom SMTP email accounts on every plan with automatic rotation across accounts during campaign sending.
Use Case:
An agency managing outreach for 15 clients connects 10 email accounts per client (150 total) and rotates sending across all accounts to maximize deliverability and daily volume.
Proprietary warmup system that gradually increases sending volume on new accounts by generating realistic email conversations with Instantly's warmup network, building sender reputation over 2-4 weeks.
Use Case:
Warming 20 new domains simultaneously before a product launch, ramping each from 10 to 200+ daily emails while maintaining 95%+ inbox placement rates.
Real-time tracking of bounce rates, spam scores, and deliverability metrics per account with automatic pausing of problematic accounts before they damage domain reputation.
Use Case:
Detecting when a specific email account's spam score rises above threshold and automatically pausing it while alerting the team, preventing reputation damage across the entire domain.
Centralized inbox aggregating responses from all connected email accounts with threading, sentiment analysis, auto-categorization, and quick-reply functionality.
Use Case:
Managing replies from 75+ email accounts in one view, quickly identifying positive responses and qualified leads without switching between dozens of email inboxes.
Email sequences with configurable follow-up steps, conditional logic, A/B subject line and body testing, timezone-aware scheduling, and personalization variables from CSV imports.
Use Case:
Creating a 5-step follow-up sequence that adjusts messaging based on whether the prospect opened previous emails, with A/B testing two different value propositions.
Server & IP Sharding and Rotation system (Light Speed plan) that assigns dedicated IP pools to your campaigns with automatic rotation of flagged IPs to maintain deliverability.
Use Case:
Enterprise teams sending 500,000+ emails monthly who need isolated IP reputation and automatic failover when individual IPs get flagged by email providers.

Instantly works with these platforms and services:
We believe in transparent reviews. Here's what Instantly doesn't handle well:
There's no limit on any plan. Users commonly connect 50-200+ accounts across Gmail, Outlook, and custom SMTP. The platform handles automatic rotation across accounts during sending. The practical limit is how many email accounts you can create and manage — each needs proper SPF/DKIM/DMARC configuration.
Typically 2-4 weeks for new domains. The warmup system gradually increases from ~10 to 200+ daily emails per account, generating realistic conversations with Instantly's warmup network. Fresh domains need the full warmup period; established domains with existing reputation can ramp faster.
The outreach plans start at $47/month, but most serious users spend $76-150+ monthly. You'll likely need the Hypergrowth plan ($97) for A/B testing, plus the leads database for finding prospects (separate pricing), plus the cost of purchasing and maintaining multiple sending domains ($10-15/year each) and email accounts.
Yes, you can connect any SMTP server including G Suite, Office 365, and dedicated email services like SendGrid or Amazon SES. Setup requires SMTP credentials and proper SPF/DKIM authentication. Custom SMTP gives more control over sending infrastructure but requires more technical configuration.
Instantly's key advantage is unlimited email accounts on every plan — Lemlist charges per seat. Apollo offers a broader platform with built-in prospecting, CRM, and multi-channel outreach but at higher prices. Instantly is the most cost-effective choice for pure email outreach at high volume; Apollo wins for all-in-one sales workflows.
