-- Pre-send email verification columns on contacts.

-- Suppression today is reactive: we only stop sending to an address *after* it
|
|
-- hard-bounces or complains, so every bad address costs a real bounce against
|
|
-- our sending reputation. These columns let the control plane verify an address
|
|
-- (syntax -> MX -> SMTP RCPT probe -> catch-all detection) before any worker
|
|
-- sends to it, turning a future hard bounce into a zero-cost pre-send drop.

|
-- status values mirror emailverify.Status: 'valid' | 'risky' | 'invalid' |
|

-- 'unknown'. New contacts default to 'unknown' so the verification scheduler
|
|
-- picks them up; the pre-send gate only ever drops 'invalid'.
