Custom Mailing List Fields

Here’s a true power-user feature for those of you who’ve integrated BookFunnel with your mailing list provider. You can now send extra data along with the reader’s name and email address, like the book they received, which marketing effort brought them in, or where they came from (Source: BookFunnel!).

Target every Giveaway page on BookFunnel to a different list and segment them any way you like with custom fields. Oh, and of course, you can also use all of those cool new variables in your fields to pass along whatever else you could want.

How To Use Custom Mailing List Fields

  1. To send subscriber data in a custom field, you must first have created the field on your mailing list account. BookFunnel will not create a new field for you, but it will populate a field you have already created. Learn how to create a custom field on ActiveCampaign, Aweber, ConvertKit, MailChimp, and MailerLite.
  2. Create a new giveaway page or edit an existing giveaway page.
  3. Click Mailing List Settings and select your list.
  4. Scroll to the bottom of the form and click Advanced Settings.
  5. Check “Send custom fields when adding subscribers to my mailing list.”
  6. Add the name of the custom field.
  7. Add the value next to the custom field. This is the data we will pass along and it can be the book title, promotion name, or even a variable like {{date_time}}. Learn more about variables.
  8. Click Save and Close.


Why isn't my data showing up?

The field must exist on your mailing list already, and we will send data to it. BookFunnel will not create a new field for you, but we have helpfully link to each mailing list provider above and they will walk you through it in their Knowledge Base.

I checked the box to send custom fields and now it says “Source”. Can I delete “Source” and add something else?

You can delete the Source field or edit it to match the fields you have already created on your mailing list.

How do I find the name of my MailChimp field?

MailChimp allows you to set the “Field label,” but the merge tag is usually something like MMERGE9. The merge tag (not the field label) should be used on the BookFunnel giveaway page.

To find the name of the merge tag, view your list on your MailChimp dashboard. Click Settings and then select “List fields and *|MERGE|* tags”

Locate the field label and then find the tag on the right. The tag should be copied and pasted into the BookFunnel giveaway form under Advanced Settings.

Can I collect custom reader data like their birthday or favorite dessert?

This feature does not allow you to create new form fields. BookFunnel will only request the reader’s email address, and optionally their first and/or last name. These custom fields can be used to pass “secret fields”, which can be used for tracking purposes or segmenting subscribers.
