A signup people trust
Quick recallWhere do people trust you most?Think of your answer, then open.
Right after they bought or booked. The confirmation page or the first message after a booking is a good place to ask.
A signup form has one job: get a yes from the right person, with an address that works. Every extra field loses people you wanted.
What the form needs
A heading that names the offer ("Get the 10 minute morning routine", not "Subscribe"), one line on what comes after ("Plus one short email a week. Unsubscribe any time."), an email field, a button that says what happens ("Send me the routine"), and your name or logo. Leave out phone, birthday and "how did you hear about us". Ask later.
Good email tools send a short email after signup with a button to confirm. It costs a few signups from people who never click. It gives you addresses that work, proof the person agreed, and a better chance of reaching the inbox.
Where Postfjord fits today
Postfjord has its own email, under Create, then Emails, with signup forms that ask people to confirm. Sending needs a paid plan and a saved sender. These steps work on every plan:
- The Ask for their email in the DM step saves the address on the contact.
- In Contacts, filter by Has email to see everyone you collected, then press Export CSV to take the list to your email tool.
- For Mailchimp, go to Settings, Apps, connect it, turn on Keep your Mailchimp list updated, and leave New people confirm by email first ticked.

Do it
- Sketch your form on paper: heading, one line, email field, button.
- Cross out every other field.
- Press the button below and check how many addresses your automations collected.
- In Contacts, filter by Has email.
