How do you collect an email address inside a chat?

Ask for it with a collect step that validates the answer, save it to the contact, then subscribe them to email so you have a channel with no messaging window.

Do this in almost every Instagram and WhatsApp flow. It is the single most valuable thing a chat conversation can produce, because those channels close after 24 hours and email does not. A contact who gave you an email address is reachable next month; one who did not, is not.

The build:

1. Collect the email, with validation on, so a typo is caught while they are

still in the conversation.

1. Set custom field or save to the contact record.
2. Subscribe to email, so they are a real recipient rather than a stored

string.

1. Continue, and say what they will get.

Two things that change the completion rate more than the wording.

Ask after you have given something. An email request as the second message reads as a toll. The same request after the answer they came for reads as a convenience.

Say what it is for, in one clause. "So I can send the guide" converts. "To stay in touch" does not.

If the collect step keeps failing validation, look at what people are actually sending. Some paste with a trailing space, some send their handle instead. A short retry message that repeats the example fixes most of it.
