Create a form
In Audience → Signup forms, create a form for an audience, choose the fields to show and write the confirmation message.
Share it
Every form has a hosted page you can link to from social profiles or your email signature, and an embed snippet for your website.
Double opt-in
With double opt-in on, new subscribers get a confirmation email and only become subscribed after clicking the link. It keeps typos and fake addresses off your list and gives you proof of consent. Confirmed signups can start an automation, such as a welcome series.
Spam protection
Forms include a hidden honeypot field and rate limiting, so bots are dropped without bothering real people with puzzles.
