**Delivery** is what a custom sends after someone comes through: a note saying
their answers arrived, and the link to their personalised video once it's ready.
Up to three messages — two emails and a text.

None of it is compulsory. Turn it all off and your customs still work; the
results still exist, and you can hand them to your own tools instead with
[outbound webhooks](/en/customs/automation/outbound-webhooks/).

Two things to know before you rely on it. Delivery settings belong to a
published version, so a change you don't publish reaches nobody. And text
messages are charged per message, so they stay off until you switch SMS on for
your workspace.

Emails go out from a Custom One address until you send from your own domain —
see [Email domains](/en/settings/email-domains/).

- [What gets sent](/en/customs/delivery/what-gets-sent/) — the three messages,
  and why none of them is compulsory.
- [When each one goes out](/en/customs/delivery/when-each-one-goes-out/) —
  immediate for the first, a wait you choose for the second.
- [Quiet hours](/en/customs/delivery/quiet-hours/) — hold overnight messages
  until morning.
- [Personalising with variables](/en/customs/delivery/personalising-with-variables/)
  — fill in each person's name, phone and result link.
- [The delivery SMS](/en/customs/delivery/the-delivery-sms/) — what it takes to
  turn a text message on.
- [Why a message didn't arrive](/en/customs/delivery/why-a-message-didnt-arrive/)
  — the checks that explain almost every one.
