Lists and contacts

Collecting and grouping contacts, importing them, and letting people sign up themselves.

A contact is someone who can receive your newsletters. A list is a group of contacts. You always send to a list, never to individual contacts, so you need at least one.

One contact can sit in several lists. Someone can unsubscribe from one list and stay subscribed to another.

Lists

You create them under Lists. A list has a name, and you immediately see how many contacts are in it and how many people have unsubscribed.

Two options are worth calling out:

Per list you can also set a description in Dutch and English. That text appears as the heading above the signup form.

Adding contacts

There are three ways.

By hand

Under Contacts you add someone with an email address, first name and last name, and attach them to one or more lists.

Importing a CSV

Upload a CSV with columns for email address, first name and last name. You first see how many valid addresses were found, and only then do you actually import.

While importing you choose which lists the contacts are attached to. Addresses that previously unsubscribed are skipped, so you cannot accidentally pull them back in. Afterwards you see exactly how many were added, how many were already there and how many were skipped.

Letting people sign up themselves

The cleanest way, and the one that produces the best list. Every list has its own signup link that you can share anywhere.

Signing up uses double opt-in: someone enters their email address, gets a mail with a confirmation link, and only joins the list after clicking it. They can then optionally add their name. That way you know the address exists and that its owner signed up themselves.

The form on your own website

To put the signup form on your own site there are three variants, all found on the list itself:

On the iframe, change lang=nl or lang=en to pick the language.

Who is on a list, and how they got there

In the list overview, click the contact count of a list to see the members of that one list. Per person you get the status, the source, the date they subscribed and, if they left, the date and reason they unsubscribed.

The source tells you how someone ended up on the list:

An unsubscribe carries the same kind of detail: the unsubscribe page, the unsubscribe button in the mail client, unsubscribing from everything, an undeliverable address, a spam complaint, or by hand.

You can filter on status and on source, and export the list as a CSV including every date and reason. That gets you, in a few clicks, who signed up through the signup form and who unsubscribed from the mail.

Memberships from before September 2026 have no source and show as Unknown. That is not a mistake, the information simply was not recorded back then.

Managing contacts

In the contacts overview you can search, sort and filter by list. Per contact you see which lists they are attached to, and you can toggle that. Hover a list label to see the status, the source and the date. Filter on a list and the source appears as its own column.

One thing to watch: unticking a list in the edit window removes the whole membership, source and signup date included. To only unsubscribe someone while keeping that history, click the list label in the overview instead.

Someone who unsubscribed from everything gets a clear label. They receive no newsletter from your page at all, whichever lists they appear in. That is deliberate: respecting an unsubscribe is not optional.

Addresses that hard bounce or file a spam complaint are suppressed automatically. That protects your sender reputation, and with it whether your mail arrives at all.

Exporting data

You can export the data of a single contact, or of all your contacts at once. The single-contact export is exactly what you need when someone files a subject access request under the GDPR, and it holds the subscribe and unsubscribe source per list.

The all-contacts export has an extra column naming the source per list. For more detail, such as the separate dates and the unsubscribe reason, use the export on a list's members screen.
