In my website I already have a multiple customers, so I have used Advanced Import addon to import all customers in a bulk. But here problem is the customer did’t receive confirmation email as well as welcome email.
Yes, it’s correct, the import just updates the database. You can import on a specific list and then create an email to send a welcome message or a request for confirmation.
Thank you for the quick response, how to create an email to send a request for confirmation mail, because initially i have set status as “not confirmed”
Create a newsletter and set it to be sent to not confirmed. In that newsletter you need to add a button with link {subscription_confirm_url} (it’s a placeholder) so that button, once clicked, will confirm the specific subscriber.
