Does Mission Inbox replace Instantly?

No. Instantly manages cold email campaigns, lead workflows and replies. Mission Inbox works underneath it as the sending infrastructure layer.

Can I send Instantly campaigns through Mission Inbox?

Yes, where the setup supports it, Instantly campaigns can be routed through Mission Inbox so your team can keep using Instantly while sending through dedicated infrastructure.

Why use Mission Inbox with Instantly?

Instantly helps teams run outbound campaigns. Mission Inbox gives teams more control over the infrastructure behind those campaigns, including domains, mailboxes, routing and monitoring.

Is this useful for agencies using Instantly?

Can I use different domains for different Instantly campaigns?

Yes. Teams can separate campaigns by domain, mailbox, client, team or sending environment, depending on how their Mission Inbox account is configured.
