Your reputation. No roommates.
One verified domain per account. It reads like a restriction. It's the vetting.
Every provider will let you verify a domain. Most will let you verify fifty. That sounds generous. Think about who needs fifty.
An agency, sometimes. Mostly it's the accounts that plan to burn through them: verify one, send until the reputation is gone, verify the next. Fifty domains is a feature built for the sender you don't want to share a wire with.
Transmit gives you one. A domain you own, that you verified, that carries your name in the from line and your signature on every message. Your DKIM key, and you can bring your own. Your reputation. Nobody else's mail sits beside it, and nobody else's mistakes count against it.
What yours actually means
- The reputation that follows your domain is built by your mail alone. There is no shared sending domain to inherit a stranger's history from, and no pool to be dragged down by.
- We check the domain before the first send. A domain registered days ago doesn't get in. That isn't an address, it's a disposable, and disposables are how bad senders get onto a good line.
- Bounces and complaints are watched on your account, and enforced. A bad list gets paused before the inbox sees it. That isn't us policing you. That's us keeping your reputation worth having.
The inbox has a memory. It remembers who sent what from where, and it decides what to do with your next message based on that. Every provider that pools reputation is asking the inbox to remember you as part of a crowd. We'd rather it remembered you.
One domain. Your name on the door. It isn't a limit on you. It's a limit on the people who would otherwise be living in your building.
