⚠️
Deliverability: platform tools reduce risk, they do not guarantee inbox

Domain reputation, sending ramp, list hygiene, and email content determine inbox placement more than any platform feature. Verify domain health and blacklist status before attributing low reply rates to the tool.

How to Choose

Which tier fits your team: 3 decision criteria

One variable narrows the field fast: whether the engagement platform must also govern deal management and forecasting. If yes, only Outreach or Salesloft qualify. If no, the remaining five tools cover sequence execution at significantly lower cost.
