One of the requirements of GDPR is that you should get explicit consent from your subscribers. This feature will let you add a consent checkbox to your MailMunch opt-in forms.
Step 1) Create or Edit your Opt-In Form
Go to edit your opt-in form and then go to the "Fields" step.
Step 2) Click "Add New Field"
It will show you the options for fields that you can add to your form. Choose an existing consent field or click "New Consent Field".
Step 3) Change Legal Text
Step 4) That's it!
The consent field will be added to your form!
Step 5) Proof of Consent
Once the subscribers have given explicit consent, you can see the proof on their subscriber page.
