Instantly review
High-volume cold email platform with unlimited inboxes and built-in warm-up.
Instantly is a cold email platform built for volume. Unlimited email accounts, automated warm-up, inbox rotation, and a lead database. The go-to sequencer for agencies and teams sending 10K+ emails per month.

The bottom line on Instantly.
Instantly is our primary sequencer for high-volume cold email. The unlimited inbox model makes it the most cost-effective option for agencies, and the warm-up network is solid. Not the most feature-rich platform, but it does volume sending better than anyone else at this price point.
Best for
- ✓Agencies managing multiple client campaigns
- ✓High-volume senders (10K+ emails/month)
- ✓Teams that want simple setup without complexity
Not for
- ✕Enterprise teams needing CRM-native workflows
