# Merge Fields

Merge fields allow you to store personalised data from individual contacts, which you can then use to personalise campaigns in Mailchimp. 

The simplest example is first names or last names. Each merge field has a merge tag, for example \*|FNAME|\* for the merge field "First name". You can then use the merge tags as placeholders in campaigns to personalise them. However, this does not only work with names, but also with other information. 

In addition, the merge fields are not only used to personalise campaigns, but also to segment your audience. To stay with the (in this context meaningless) example: With the help of the merge fields, you could create a Mailchimp segment with all contacts with the first name "Anton" in order to target all Antons. As I said, the example makes little sense. With the following merge fields synchronised by beabee with Mailchimp, it makes more sense:

| beabee field                | Mailchimp merge field | Example      |
| --------------------------- | --------------------- | ------------ |
| First name                  | FNAME                 | John         |
| Last name                   | LNAME                 | Doe          |
| Contribution monthly amount | C\_MNTHAMT            | 5            |
| Contribution period         | C\_PERIOD             | annually     |
| Contribution description    | C\_DESC               | £60/annually |
| Referral code               | REFCODE               | WF301        |
| Polls code                  | POLLSCODE             | WF678        |

For example, you could use Merge Fields to segment your Mailchimp audience by contribution amount or differentiate between monthly and annually paying members.

To use the merge fields, you need to set them up once in Mailchimp. How to do that, you will learn on the next page.
