Send
Mailing campaigns. Paced, suppression-aware, and they stop themselves.
No outreach domain yet
Campaigns send from outreach domains only, and every domain you have is transactional. A burnt outreach domain costs $14 and a re-registration; a burnt transactional domain takes down receipts and password resets for that product. Register a throwaway domain and add it under Domains before running anything.
No campaigns. One needs a list, a campaign template and a mailbox on an outreach domain.
Every send checks four things first: the domain’s plane, global suppression re-read per contact, the ledger of who has already been mailed, and the daily cap. A campaign whose bounce rate passes 5% stops and blocks itself.
