Instantly is designed to send high volumes of cold email across many mailboxes. FollowThroo sends less volume by design and spreads the sequence across email, LinkedIn and WhatsApp, pacing each channel to its own limits.
Instantly's pricing page does not list LinkedIn or WhatsApp. In FollowThroo they are ordinary sequence steps, and a reply on either stops the email follow-ups too.
Instantly includes a large B2B lead database. FollowThroo does not sell data; leads come from LinkedIn through the Chrome extension, CSV imports and inbound sources.
