They rent you a seat on shared IPs.We own the infrastructure.
Instantly and Smartlead send your email cheaply - on shared pools you fight spammers for. Ken runs on infrastructure we own and pre-checks every email against a replicated spam filter, so it reaches the inbox instead of the spam folder.
Cheap to Send. Costly to Land.
What They Are
Affordable email sequencers. They take your list and your copy and send it. Good at volume and price.
Where They Fall Short
Shared infrastructure means you compete with every other sender - including the spammers - for placement. No data, no real personalization, no qualification. The sticker price is just the start: domains, inboxes, verified lists, and warmup are all extra, often pushing the real cost to 5-10x. And when deliverability slips, it's on you to fix.
