Double Opt-In

What Double Opt-In Does

Double opt-in asks a person to confirm their email address before Mailrith treats the signup as Active. In Mailrith, double opt-in is configured on the form or landing page that collects the signup.

Use double opt-in when you need stronger proof that the email address owner asked to subscribe. It also helps protect deliverability because mistyped addresses and someone else's email address do not become Active unless the address owner confirms.

Mailrith saves the confirmation outcome and can show confirmation-link engagement from the Subscriber's History tab.

Set Up Double Opt-In On A Form

Set Up Double Opt-In On A Landing Page

4. Open Settings > Page Submit.

10. Submit the public landing page with a test email address and confirm that the Subscriber stays Unconfirmed until they click the confirmation link.

Confirmation Email And Success Page

The confirmation email should have one clear job: ask the Subscriber to click the confirmation link. Keep it short, remind the Subscriber what they asked to join, and avoid extra offers or unrelated links.

After the Subscriber clicks the confirmation link, Mailrith can show a success message or redirect them to a URL you provide.

• Success message: best for a simple confirmation, such as "Thank you for subscribing."
• Redirect URL: best for a welcome page, download page, webinar confirmation page, or onboarding screen.

Review Double Opt-In Activity

1. Click Subscribers in the left sidebar.
2. Search for the Subscriber by email address or name.
3. Click the Subscriber row to open the profile drawer.
4. Open History.
5. Review the signup and confirmation activity for that Subscriber.

Where Double Opt-In Applies

Double opt-in applies to the form or landing page where you turned it on. Subscriber tags still help with targeting and organization, but tags no longer decide whether a signup needs confirmation.

Public Mailrith form and landing-page submissions can use their own double opt-in settings. Zapier subscriber actions and Facebook Lead Ads sync do not expose a double opt-in switch and do not send these confirmation emails. Use a Mailrith form or landing page when a signup path must require confirmation before the Subscriber becomes Active.

Troubleshooting Double Opt-In

• The confirmation email is not sending: confirm the workspace has an enabled Email Delivery Connection.
• The form or page cannot be saved: make sure the confirmation subject and body are not blank when double opt-in is enabled.
• The link is missing from the email: add the confirmation link token back into the email body.
• The redirect URL is rejected: enter a complete URL that starts with https:// whenever possible.
• A Subscriber is still Unconfirmed: ask them to open the latest confirmation email and click the confirmation link.
