The main difference
Boomerang is a personal email-productivity add-on that helps you schedule messages and reminds you to follow up from your own inbox. Outsales is an autonomous platform that writes and sends the follow-ups for you across many contacts, scores buy intent and manages the CRM. Different category: a personal email assistant vs an end-to-end sales system.
Choose Outsales if…
- You want one autonomous system for outbound, follow-up, CRM and intent
- You'd rather pay a flat $99/mo than per seat or for add-ons
- You want to keep your CRM and send from your own inbox
