# When do you need to ask subscribers for permission again?

> Read when you need to ask existing subscribers for permission again and when it is not necessary.

Who you may and may not email is governed by the Dutch Telecommunications Act (Telecommunicatiewet). You can read about the conditions set by this law and the legal bases under the GDPR in [Legal bases for email marketing](/grondslagen-voor-verwerking).

## When do you need to ask for permission again?

Under the GDPR, you must be able to clearly demonstrate that the people you want to email have actually given permission for this. In the case of a customer relationship, you must be able to show when and how this person became a customer.

If you can look this up for each subscriber, you do not need to ask for permission again. Usually, one of these three situations applies:

| Situation                                                             | Ask for permission again |
| --------------------------------------------------------------------- | ------------------------ |
| You can look up that someone signed up for your newsletter            | Unnecessary              |
| You can look up that someone placed an order or requested information | Unnecessary              |
| You no longer know how someone ended up on your list                  | Possibly required        |
