Pricing Comparison
Instantly.ai offers aggressive pricing starting at $30/month for unlimited email accounts, making it one of the cheapest options for volume cold email. The B2B lead database is an additional subscription. ProspectAI's custom all-inclusive pricing is higher but covers AI personalization, multi-channel execution, contact data, and managed infrastructure. Teams focused purely on email volume may find Instantly cheaper; teams focused on meeting quality and multi-channel outreach typically get better ROI from ProspectAI.
Who Should Choose Instantly.ai
Instantly.ai is the right choice for agencies and teams that prioritize sending volume across many email accounts at the lowest possible cost. If you're running high-volume email campaigns with your own templates and lead lists, and multi-channel outreach isn't a priority, Instantly's unlimited sending model is hard to beat on price.
Who Should Choose ProspectAI
ProspectAI is the right choice for teams that want quality over volume. If you want every email to be individually researched and personalized, coordinated with LinkedIn and phone touchpoints, and managed by an autonomous AI agent — rather than blasting templates across unlimited mailboxes — ProspectAI delivers more qualified meetings per dollar.
