We do not have a template asking for permission as it's part of our terms and conditions that contacts you import should already be permission-based. If you want to obtain permission from them again, we have a process called Confirmed Opt-in which means you send them an email asking them to confirm that they want to continue receiving your emails. If they do not respond, they will not get your emails again and you cannot manually add them back in as active contacts in your account. This applies to new sign ups and you can also send existing contacts a manual opt in email. Here are the links on how that works for your reference:
Please go over that so you can decide whether you want to do this process as it may reduce your contacts numbers if they do not confirm at all. Thanks Paul! Please let me know if you have any other questions
