Instantly
Instantly powers our high-volume email campaigns with unlimited sender accounts, centralized master inboxes.
Why it’s in our stack:
Scaling cold email used to mean paying per seat for every single inbox you connected. Instantly changed the architecture of outbound by allowing unlimited sending accounts.
We use it to distribute sending volume safely across dozens of domains, protecting our clients' primary domains from spam filters. Their built-in automated warmup network and unified "Master Inbox" make managing responses across hundreds of campaigns incredibly efficient for our team.
