I have a lot of users who did not confirm the email with double-opt-in and are now in my not confirmed list. I found this post: https://sendy.co/forum/discussion/1641/the-script-i-use-to-import-contacts-via-api
But it would just send out the regular eMail when you signed up the first time.
In order to let the customer (especially older signups) know why I'm sending this confirmation again it would be great if someone knew how I could send an eMail with this list and make sure they would receive an extra special email with some text like:
"We are sending you this email because you signed up in the past but did not confirm the double opt-in. If you missed the email at the time you can do this now and receive our eMail."
Unfortunately I'm not good in coding but I think this would be helpful for a lot of people and would be really useful to get all the people to signup who missed the email or it went to their spam folder.
Thanks.
