Boomerang review

Boomerang started as a send-later tool for Gmail and still centers on follow-up rather than analytics. Its response tracking brings a message back to your inbox if nobody replies by a date you choose, which for many salespeople matters more than knowing about an open. The plan table also lists read receipts and click tracking, plus meeting scheduling with Meeting Poll, bookable schedules and suggested times written into one email. The free Basic plan allows 10 message credits a month, and new accounts get a 30-day trial of Boomerang Professional without a credit card. Personal costs $4.98 per month billed annually but supports only Gmail accounts, so anyone on Google Workspace needs Pro at $14.98. Premium at $49.98 is the top tier, and the plan table lists Salesforce and CRM integration among its features. Boomerang does not work in Outlook through this product, and its tracking reports are lighter than Yesware's or Mailbutler's.
