原文外掛簡介
Double Opt-In adds a mandatory email verification step to your Contact Form 7 and Avada forms.
When a visitor submits your form, the original mail is not sent immediately. Instead, the plugin:
Stores the submission in a secure database table.
Sends a confirmation email with a unique, time-limited link.
Only after the visitor clicks that link is the original form mail delivered.
This ensures:
Only valid, verified email addresses reach your inbox.
GDPR / DSGVO requirements are met with proper consent tracking, IP logging, and data retention.
Your database stays clean and reliable — no fake or mistyped addresses.
Seamless integration with Contact Form 7 and Avada Forms.
Enable Double Opt-In per form, customize confirmation emails with a visual editor, and manage data retention with ease.
How It Works
A visitor fills out your Contact Form 7 or Avada form and clicks submit.
The plugin intercepts the submission, stores the form data, and generates a unique hash.
A confirmation email is sent to the visitor’s email address containing a verification link.
The visitor clicks the link. The plugin verifies the hash, marks the opt-in as confirmed, and sends the original form mail (as if the form was just submitted).
The confirmed opt-in is logged in the admin dashboard with timestamps and IP addresses for full GDPR compliance.
