How can I remove Email Confirmation, Date of birth, Phone fields from Registration form
For legal reasons, of course. Nowadays GDPR must be taken very serious, you can't allow people under a certain age to join your site, this is why we need a dob. Phone is not mandatory as far as i can remember.Why would anyone wanna enter the phone, DOB for signing up for an email marketing platform?
Some fields are required and the platform expects to get them, so it will be tricky to go around this.Would I be able to have it removed from a dev without breaking stuff from future updates?
You can create customer group and assign delivery server to group then in Backend > Settings > Customers > Registration you can choose a group where the customer will be moved after registration.No, I mean when someone registered a new account and they want to blast out email campaign, we will need to set the delivery server manually for them or it can be set automatically?
