Our take
Instantly wins for high-volume agency-style outbound where deliverability is the bottleneck. The warmup network + unified inbox + mailbox rotation are best-in-class. For corporate SDR teams using Outreach/Salesloft, Instantly is overkill. Founders sending 500-5000 emails/week from multiple mailboxes — this is the pick.
Who it's for: Agencies, founders, solo SDR teams doing high-volume cold email.
