Double Opt-In Verification Setup

Double opt-in ensures that new subscribers explicitly confirm their email address before receiving marketing campaigns, maintaining high domain reputation and virtually eliminating bounce rates and spam traps.

How Double Opt-In Works in MANZA

1. A visitor fills out an opt-in form on your site.
2. The contact is created with status `PENDING_CONFIRMATION`.
3. MANZA automatically sends a verification email containing a secure 1-click confirmation link.
4. When the subscriber clicks the link:
5. Their status changes to `ACTIVE`.
6. They receive assigned tags and list memberships.
7. Any welcome email or WhatsApp drip sequence is triggered.

Enabling Double Opt-In on a Form

1. Open Marketing Suite > Forms and edit your form.
2. Under Opt-In Settings, toggle:
3. Mode: Select `Double Opt-In (Recommended)`.
4. Select your Confirmation Email Template:
5. Choose a pre-built template or customize the body text.
6. Include the {{confirmation_url}} merge tag inside your call-to-action button.
7. Select your Sending Identity:
8. Choose your verified custom SMTP sender (e.g., newsletter@yourdomain.com).
9. Save your form settings.

Best Practices

• Deliverability: Keep the subject line clear and actionable (e.g., *"Please confirm your subscription to MANZA Insights"*).
• Expiration: Verification links remain valid for 48 hours. If unconfirmed, unverified contacts do not count against your email marketing quotas.
• Single Opt-In Fallback: For low-friction internal lead magnets or lead forms backed by WhatsApp phone verification, you can toggle `Single Opt-In` anytime.
