Instantly

Cold email infrastructure: unlimited accounts, warmup, and AI sequences — Apollo's more deliverability-native cousin for teams whose product is the send, not the database.

Product preview

Overview

Instantly is the sender Apollo is not: warmup, many inboxes, the unibox, AI that writes the sequence. Lemlist and Smartlead sit in the same aisle. Data still has to come from somewhere.

Deliverability is the product and the risk. If the job is 'the email must land,' this is the OS. If the job is 'find the person,' Apollo or Clay is the other tab.
