Decision Guidance

Use Premium Inboxes when: You're an agency or business scaling cold email fast, lack technical team for DNS setup, and need stable inbox quality with unlimited replacement guarantees. Best for high-volume senders prioritizing deliverability.

Consider alternatives if: You have in-house engineering to handle DNS setup, limited budget with under 50 inboxes, or need sequencers not supported by Premium Inboxes.
