Instantly AI
Cold email automation platform with AI writing and unlimited sending accounts
From $47/mo
What is Instantly AI?
Instantly AI is built for serious cold email infrastructure — the tool of choice for lead generation agencies and outbound-heavy sales teams who need to send thousands of emails per day without landing in spam. Its key differentiator is unlimited email accounts on a single plan, allowing teams to spread email volume across multiple sending addresses and warm them up automatically to maintain deliverability.
The AI Writer generates campaign sequences from a brief description of your offer and target audience. The AI can personalize emails using company and prospect data, and the Spintax feature creates infinite variations of email copy to avoid spam filter pattern matching. Campaign analytics show open rates, reply rates, and conversion data at the campaign and account level.
The Lead Finder database (450M+ B2B leads, sold as Instantly credits) allows you to find and contact leads without leaving Instantly — a full cold outreach workflow in one platform. The Outreach Growth plan costs $47/month on monthly billing (checked 4 October 2026), with cheaper rates on annual billing. For agencies running 10+ campaigns simultaneously, it is significantly cheaper and more capable than most alternatives.
