Instantly is excellent at sending cold email at scale. If what you are missing is the list, the writing and the time to run it, here is how DemandSwarm compares.
Instantly is a sending platform. You connect as many email accounts as you like, it warms them up, rotates sending across them and tracks results. Its outreach plans run from $47 to $358 a month, and the higher plans include an AI agent that helps with replies.
It is a strong choice for someone who likes to run outreach hands-on: building lists, writing sequences, testing subject lines and managing mailboxes. Many agencies and growth teams use it for exactly that.
DemandSwarm does the work around the sending. You describe who might buy from you; the swarm finds those businesses, picks the right person at each one, and writes a short email from what that business's own website says.
It also builds and runs the sending network for you, with separate domains and gradual warm-up, and it puts replies on a board with an answer drafted. You spend your time on the businesses that wrote back.
