iris vs Instantly
iris is built around quality; Instantly is built around volume.
why iris?
one verified domain, not inbox rotation
iris sends from your verified domain only. Instantly's model rotates across many sender mailboxes to spread volume - effective at scale, but a different deliverability strategy than iris is set up for.
AI-drafted per contact, not high-volume sequences
Instantly is optimized for sending the same sequence to many contacts. iris is optimized for drafting different messages for each contact, then sending fewer of them.
social DMs in the same inbox
Instantly is email-only. iris threads email, Instagram, and Twitter conversations together per contact.
no warm-up tooling
iris doesn't ship inbox warm-up because the volumes iris sends don't require it. if you need warm-up, you probably need a different tool.
