Seventh FeedCold email and B2B outreach tools compared: Instantly vs Salesrobot vs Gojiberry AI vs Prosp
Data as of 2026-11-11. Rechecked every quarter.
Outbound teams usually split between high-volume cold email with rotating mailboxes and warm-signal outreach on LinkedIn. We compared four platforms across both approaches: Instantly ($37/mo), Salesrobot ($99/mo), Gojiberry AI ($79/mo), and Prosp ($59/mo).
Instantly remains the standard for pure cold email volume because it charges a flat fee for unlimited sending mailboxes and warmup. Salesrobot and Prosp add LinkedIn sequence steps (including automated voice notes) when prospects ignore email. Gojiberry AI filters prospects by 15+ buying signals before sending so you contact fewer leads with higher reply rates.
