When creating a new Custom Field you will have to choose its data type, using a drop-down menu.
You can choose any of the data types available:
Choosing the Text data type means that your custom field will necessarily be a text. This data type can be very useful on such occasions such as when you want to place your subscriber's first name, surname, location, etc. inside your email marketing campaign.
The Number data type is used for custom fields which should be containing numeric values. Wherever a number needs to be used as a custom field (e.g. counting the number of times a subscriber has clicked on a link or the number of times your customers have purchased a product from your site,) this is the data type you need to use.
- Date Time
The Data Time data type pertains to a date. This could be used for a range of things, from the date of subscription, an anniversary, to a subscriber's birthday or anything you can come up with. When you need to set a date as a custom field, this is the data type you are looking for.
- Single Select Dropdown
Are you asking your subscribers to make a choice out of a dropdown list? This is the custom field for this type of application. You will need to set the different options - and your users will be able to make a single selection out of those.
The Checkbox data type is of the Yes/No variety, as it leaves it to your subscriber to tick or not tick a box pertaining to a parameter you have previously defined. This data type can be used efficiently when asking your subscribers for their preference by adding options for them to choose between. They can then tick whichever they want and help you make your campaigns more efficient.
